Frequently Asked Questions - Hercules HDS800 Baumr-AG

What type of engine oil should I use for the Hercules HDS800?

Use SAE 10W-30 automotive engine oil for general use. The engine oil capacity is approximately 1.1 litres. Always check the level with the dipstick and ensure it is at or near the maximum mark.

How do I start the petrol engine on the HDS800?

1. Ensure fuel tap is ON. 2. Set choke to COLD if engine is cold. 3. Turn ignition switch to ON. 4. Set throttle just off SLOW. 5. Pull starter cord slowly until resistance, then pull rapidly. Allow cord to rewind slowly. Warm up and adjust choke to HOT.

What hydraulic oil is recommended and how do I check the level?

Use 10WT AW32, ASLE H-150, or ISO 32 hydraulic oil. The capacity is approximately 22 litres. Check the level via the sight glass on the rear of the oil tank when the machine is on level ground. Level should be at 70–80% full.

Can I use the log splitter in vertical and horizontal positions?

Yes, the HDS800 can operate in both horizontal and vertical positions. To switch, pull the spring-loaded release pin and lift the ram assembly to the vertical position. Ensure the ram is locked securely before use. Do not change position while the engine is running.

What safety precautions should I take when using this log splitter?

Always read the manual. Operate only outdoors to avoid carbon monoxide poisoning. Keep bystanders at least 30 m away. Wear safety goggles, hearing protection, gloves, and steel-toe boots. Keep hands away from moving parts and splitting wedges. Never operate under the influence of drugs or alcohol.

How do I maintain the hydraulic system?

Check hydraulic oil level before each use. Lubricate the ram slide with grease. Inspect hoses and fittings for leaks or damage. Change hydraulic oil every 200 hours or if it appears milky. Use only recommended oil type. Relieve pressure before maintenance.

What are the towing requirements for the HDS800?

Ensure the ram is locked in horizontal position. Secure the tow arm to the vehicle hitch. Raise the jockey wheel. Connect trailer lights to the vehicle. Check tyre pressure. Do not tow on public roads. Follow local laws.

Why won't the engine start?

Check fuel tank level and ensure fuel tap is ON. Verify ignition switch is ON. If the engine is flooded, set choke to HOT and pull starter cord with ignition OFF to clear excess fuel. Check spark plug for carbon buildup or damage. Ensure engine oil level is correct.

What should I do if a log gets jammed on the wedge?

Do not fully retract the ram. Release pressure and insert a wooden wedge under the log at the log stop. Use the splitter to push the log over the wedge to free it. Alternatively, use a crowbar. Never strike the log to free it.

How do I store the log splitter long-term?

Clean the machine. Drain the fuel system. Remove spark plug, pour 10 ml of clean engine oil into the cylinder, and pull starter cord to distribute. Reinstall spark plug. Store in a dry, well-ventilated area out of reach of children.

different models may exist. Failure to follow the checklist and carry out the procedures correctly may result in making the product warranty void. The product is NOT supplied with engine oil, although traces of oil from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the engine before use – see Engine Oil. Failure to add engine oil will void the product warranty.

Assembly - HDS800 / HPS800

2 or more persons are required for assembly. • Suitable tools (not supplied) are required for correct assembly. • Check all parts have been supplied and are in good condition before assembly. • Washers are to be placed under nuts unless otherwise stated. • Firmly secure all

1. Attach the tow bar assembly (A) to the mounting bracket at the top of the oil tank assembly (B) using 2 M12x100 bolts (C), 2 M12 washers (D) and M12 nuts (E). Once attached, lower the jockey wheel (1) before continuing assembly.

1. Connect the oil supply hose (F) to the oil tank port (2) and secure it using the supplied hose clamp.

1. Remove the split pin (G), M20 castellated nut (H) and M20 washer (I) from the axle on either end of the oil tank assembly. Remove any dust covers from the wheel (J) hubs – be careful not to allow any dirt etc to get into the wheel bearings. Then, slide each wheel onto the axle – be careful not to allow the bearings to come out of the wheel hub. Place a M20 washer onto the axle, then the M20 castellated nut. After tightening the nut, insert a split pin through the nut and axle, then bend the pin legs to prevent it from falling out. Install the hub caps (K) to seal the bearings – these may require tapping on with a mallet or soft hammer etc.

1. Remove the pre-assembled nuts from the rear lamps (L), then run the lamp wiring through the hole in the lamp mounting (3) on each mudguard (M), then secure the lamps using the previously removed nuts.

NOTE: the wiring for the right-hand side tail light is longer than for the left side.

1. Attach each mudguard to the oil tank using 3 M10x30 bolts (N), M10 rubber washers (O), M10 washers (P) and M10 nuts (Q). Place the rubber washers between the mudguard and the oil tank.

1. Attach the engine mounting bracket (R) to the oil tank mounting (4) using 4 M10x30 bolts (N), M10 washers (P) and M10 nuts (Q).

1. Remove the hinge pin (5) and R-clip (6) from the underside of the hydraulic ram assembly (S). Lower the hydraulic ram assembly onto the oil tank, so the hinge pin is aligned with the pivot (7) on the ram mounting (8). Re-install the hinge pin so the hydraulic ram assembly is secured, then insert the R-clip to

prevent the pin from falling out. Ensure that the spring-loaded pin (9) engages with the hydraulic ram assembly to lock it in the horizontal position.

When making the high-pressure hose connections, it is ESSENTIAL that O-rings are correctly installed and that the connector internals are absolutely clean. • The hydraulic ram may be supplied pre-filled with oil – be aware that when removing the hose plugs that oil may escape from the hose.

1. Remove the dust cover from the oil tank "return" hose connector / filter (10), then install a 17mm O-ring (T) to the connector. Remove the plastic sealing plug from the "return" hose (11) connector (hose with 90° elbow at the end). Note that there may be an O-ring behind the plug – do not make a connection using 2 O-rings. Connect the hose to the oil tank connector and firmly secure it. Ensure that the hose is routed as shown – this will prevent the hose being stressed when the hydraulic ram is used in the vertical position.

1. Slide the pump coupling spacer (U) onto the engine (V) output shaft (12), then place the woodruff key (W) into the slot in the output shaft. Then, slide the pump coupling (X) onto the output shaft (because of the woodruff key, the coupling will fit on one way only).

1. Bring the pump assembly (Y) into position against the engine. Ensure that the pump couplings engage as shown, then attach the pump assembly to the engine using 4 M8x25 bolts (Z), M8 washers (AA) and M8 spring washers (BB). The engine is now ready to be mounted to the machine.

Before tightening the pump assembly mounting bolts, pull the engine starter cord several times (remove the spark plug first to make spinning the engine easier) and check that the engine-pump operates smoothly. If not, adjust the position of the pump as required. When the coupling operates y, tighten the fasteners.

1. Place 4 rubber engine mounts (EE) and M10 large washers (FF) onto the engine mounting bracket (R), as shown. Carefully lower the engine onto the mounts and secure it using 4 M10x75 bolts (GG), inserted from under the engine mounting brackets, M10 washers (P) and M10 nuts (Q).

1. Connect the oil supply hose (F) (from oil tank) to the pump inlet port (13) and secure it using the hose clamp.

1. Remove the dust cover from the oil pump "outlet" hose connector (14), then install a 17mm O-ring (T) to the connector. Remove the plastic sealing plug from the "outlet" hose (15) connector. Note that there may be an O-ring behind the plug – do not make a connection using 2 O-rings. Connect the hose to the oil pump connector and firmly secure it. Ensure that the hose is routed as shown – this will prevent the hose being stressed when the hydraulic ram is used in the vertical position.

1. Attach the log cradle with log table mounts (HH) to the right-hand side of the hydraulic ram assembly using 4 M10x30 bolts (N), M10 washers (P) and M10 nuts (Q).

1. Attach engine (T) to the rear frame (G) using the 4 previously removed M8x65 bolts, washers, spring washers and nuts.

Engine Oil

Four-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe or irreparable damage may occur if the engine is allowed to run without engine oil. The engine oil level requires regular maintenance. Check the engine oil level and ensure that the oil level is at or just under the maximum level indicator.

Always check the engine oil level before starting the engine. See Engine Oil.

Air Filter

The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal damage to it. The air filter requires regular maintenance.

Always check the air filter before starting the engine. See Air Filter.

Fuel

Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other ignition sources. • The engine must be cool before refuelling.

Adequately fill the fuel tank with the correct fuel type.

• For petrol engines, use non-ethanol unleaded petrol (higher RON values will provide best engine performance). Do not use old or contaminated fuel.
• For diesel engines, use commercial non-bio diesel fuel. Do not use old or contaminated fuel.

1. Place the machine on a flat and level surface.
2. Clean the machine around the fuel filler so that no dirt or other material enters the engine when the cap is removed.
3. Remove (rotate left) the fuel filler cap.
4. Using a funnel, carefully fill the tank with fuel. Do not fill above the top of the strainer (if equipped) or otherwise overfill the tank.
5. When finished, reinstall (rotate right) the fuel filler cap until firm. Wipe away any residual fuel from the machine. If fuel has been spilt, move the pump away from the spillage before starting the engine.

Hydraulic Oil

The hydraulic system requires adequate hydraulic oil of the correct type to operate safely and efficiently. The machine is shipped without hydraulic oil although some oil may be supplied. Check the hydraulic oil level and ensure that it is at the recommended level. See Hydraulic Oil.

Engine Starting

Before starting the engine, ensure that you have followed all procedures described in the Before Use Checklist. Failure to follow the checklist and carry out the procedures

correctly may result in making the product warranty void. The product is NOT supplied with engine oil, although traces of oil from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the engine before use – see Engine Oil. Failure to add engine oil will void the product warranty.

Different models may feature variations in design; for example, some have different engine types etc. The following procedures and images are typical to all models, however, the position or appearance of controls etc may vary. All major engine controls are identified on the machine by way of stickers or other markings.

Starting Petrol Engines

1. FUEL – Place the fuel tap (A) in the "ON" position (to the right).
2. CHOKE – If the engine is cold, place the choke (B) in the "COLD" position (to the left). If the engine is warm or ambient temperature is high, place in the "HOT" position (to the right).
3. IGNITION – Place the engine ON/OFF switch (C) or key switch (if equipped) in the "ON" ("I") position. For key switches, the "OFF" position allows the key to be removed. The "ON" position is reached when the key is rotated to the right from the "OFF" position.
4. THROTTLE – Place the throttle control (D) just off the "SLOW" position.
5. START – Slowly pull out the starter cord (E) until you feel it engage with the engine, then pull it out rapidly (use both hands if necessary). The engine should start. Allow the starter cord to rewind slowly – do not let it "snap" back.
6. WARM-UP – Allow the engine to warm-up and run smoothly. If choke is being applied, place the choke (B) in the "HOT" position.
7. THROTTLE – Adjust the throttle control (D) for the required engine speed.

If the engine does not start, repeat step 5 onward. If the engine fails to start after several attempts, refer to Troubleshooting.

Video Tutorial:

Starting Petrol Engines

Starting Diesel Engines

1. FUEL – Place the fuel tap (A) in the "ON" position.

2. THROTTLE – Place the throttle control (B) in the "RUN" position (down). Some models use a screw to secure the throttle in position – to adjust, loosen the screw and move it to the required position, then tighten it again.

3. TOP DEAD CENTRE – Slowly pull out the starter cord (D) until you feel it engage with the engine, then allow it to return to the retracted position.

4. DECOMPRESS – Place the decompression lever (C) in the "down" position, otherwise you may not be able to start the engine.

5. START – Rapidly pull the starter cord (D) (use both hands if necessary). The engine should start. Allow the starter cord to rewind slowly – do not let it "snap" back to the engine. Each time you use the starter cord, place the engine at "top dead centre" (step 3) and the decompression lever in the "down" position (step 4) first.

6. WARM-UP – Allow the engine to warm-up and run smoothly.

7. THROTTLE – Adjust the throttle control (B) for the required engine speed. Some models use a screw to secure the throttle in position – to adjust, loosen the screw and move it to the required position, then tighten it again.

If the engine does not start, repeat step 3 onward. If the engine fails to start after several attempts, refer to Troubleshooting.

Video Tutorial:

Pull-Starting Diesel Engines

Stopping the Engine

1. Place the throttle control in the "SLOW" position. For diesels, loosen the throttle control – it should automatically return to the engine OFF position (up).
2. If equipped, place the engine ON/OFF switch in the "OFF" position.
3. If equipped, place the fuel tap in the "OFF" position.

Environmental Considerations

Altitude – If the engine is being used in altitudes at or above 1500m (approximately 5000'), adjustments to the fuel system may be required. This is because there is less oxygen in the air as altitude increases, which effectively "enriches" the ratio of fuel to air going into the engine, and the higher the altitude, the richer the fuel mixture becomes. If the engine is being permanently operated at high altitude, it is recommended to have an authorised service centre make the necessary fuel system adjustments. If the engine is used occasionally at altitude (not extreme altitudes), no adjustments should be required, however, a slight decrease in engine performance can be expected.

Temperature – If the engine is being used in extremely cold or hot environments; for example, desert or snow conditions, the type of engine oil may need to be changed to suit environmental temperatures. Oil thickens as the temperature decreases and thins as temperature increases, which means that if the engine oil is not suited to the temperature its ability to properly lubricate the engine may be affected. Use the following chart to determine the correct engine oil:

Log Splitter Operation

The machine must be operated by one person only. Do not allow helpers or bystanders within 30m (90') of the machine. Bystanders should wear eye protection. • Make sure there are no nails or foreign objects in logs to be split. • Log ends must be cut square. • Branches must be cut off flush with the trunk. • Always split logs in the direction of the wood grain. • Do not load or unload logs whilst the ram is moving. • Crush / amputation hazard - keep hands away from moving parts and from splits/cracks that open in logs. • Do not remove jammed logs by hand. • Ensure that when initially retracting the ram that the timber has split and is separated from the wedge. If timber becomes jammed on the wedge and moves up when retracting the ram, do NOT fully retract the ram as this may cause injury and/or damage the machine. Remove the timber from the wedge before fully retracting the ram. • Do not change the machine set-up between vertical and horizontal when the machine is running or timber is loaded into the machine. • Ensure that the hydraulic ram assembly is locked into position before using the machine. • Before use, check the hydraulic oil level with the ram in the fully retracted position. • Make sure all fittings are secure before applying pressure. • Make sure the hydraulic hoses do not touch any hot surfaces or are in or near the splitting area. • To avoid serious bodily injury, inspect the hydraulic system (hoses, fittings and connections, and hydraulic pump) before operating the machine. Very high fluid pressure and temperatures are created in the hydraulic system. Hydraulic fluid will escape through the smallest opening and can puncture skin and cause severe injury and blood poisoning. Never check for leaks with your hands or any other body part while the hydraulic system is pressurised – use a piece of wood or other hard material that any leak will be visible on. Seek medical attention immediately if injured by hydraulic fluid. • The hydraulic oil needs to be above -12°C (10°F) before starting the engine. Cold hydraulic oil can damage the hydraulic pump. If the air temperature is below 0°C (32°F), allow the oil to warm up by extending and returning the wedge several times before splitting wood.

Note that once the engine is running, the hydraulic pumping action of the machine activates. When the engine is idling (slowest continuous running speed), the hydraulic pressure is minimal. As you increase engine speed (use the engine throttle control), the hydraulic pressure increases. Note the following recommendations:

• Operate the engine at a sufficient speed to provide the desired hydraulic pressure. This may vary on the size of the timber and species etc.
• Set-up and operate the machine on a dry and level surfaces with good footing. Do not work on mud, loose, or slippery ground surfaces, and chock the wheels before use.

• Lower the support leg (if equipped) from the towing arm position:

• Unlock the support leg (AA) from the towing position by removing the locking pin (BB).

• Swing the leg down to the low position, then secure it with the locking pin.

- Maintain a clearance of at least 2.5m (7') around the machine at all times to any combustible material.

- For suitable wood types, use the 4-way splitting wedge (CC) (if equipped). To attach, place it over the standard wedge (DD), then secure it using the winged bolt (EE) (tighten by hand only).

Splitting Logs

1. Place the log on the slide/work table (A), with one end up against the non-moving part – that is, log stop (1A) or wedge (1B).
2. Operate the hydraulic ram using the ram control lever (2). Move the lever in the direction of the log stop and hold it there for the hydraulic ram/wedge to push the forward.
3. Push the wedge into the log until it splits, then release the lever.
4. When the wedge is free from the log, move the ram control lever in the reverse direction to retract the ram/wedge.

Ensure that when initially retracting the ram that the timber has split and is separated from the wedge. If timber becomes jammed on the wedge and moves up when retracting the ram, do NOT fully retract the ram as this may cause injury and/or damage the machine. Remove the timber from the wedge before fully retracting the ram. • If the log is not splitting, do NOT keep pressure against the log for more than 5 seconds. This places additional stresses on the machine and may damage it or the hydraulic system. In such cases rotate the log 90° and attempt to split it again. If this is not successful, the log may be too hard for the capacity of the machine and should be discarded

Working with Logs

• Always set logs firmly on the slide / work table.
- Ensure that logs will not twist, rock or slip while being split.
- Ensure that logs have good contact with the splitting wedge. Splitting against the top of the wedge may break the wedge or otherwise damage the machine. Use the adjacent diagram for the safest method of splitting logs with slanted faces

Extracting Jammed Logs

• Release pushing pressure against the log. Do NOT fully retract the ram/wedge.
• Insert a wooden wedge under the log at the log stop, narrow edge under the end of the log.
• Use the log splitter to push the log over the wedge to release it. Various sized wedges may need to be tried. A crowbar can also be used to lever the log from the wedge. Do not strike the jammed log to free as this may damage the machine or launch the log.

Setting-Up the Machine in the Vertical / Horizontal Position

Some model machines can be used in the horizontal or vertical position for splitting. The vertical set-up is generally better suited to larger pieces of timber. To use the vertical set-up:

1. Secure the machine in the work position with the wheels chocked.
2. Pull out and hold the spring-loaded release pin (A).
3. Whilst the release pin is in the unlocked position, use the handles to lift the top of the hydraulic ram assembly and rotate it until it is in the vertical position.

To revert to the horizontal position, use the handles to gently lower the hydraulic ram assembly, pull out and hold the spring-loaded release pin so that the ram assembly fully lowers, then release the pin. Ensure the ram assembly is held securely before proceeding.

Towing

Before towing, ensure the axle nuts are tight and the axle nut split pins and securely in place. • Ensure that the tyres are inflated to the pressure marked on the tyre wall. • Do not tow if the tyres are worn, damaged or do not hold air pressure. • Do not tow the machine in the vertical position. Ensure that the hydraulic ram assembly is locked in the horizontal position before towing. • Do not carry passengers, or allow any person to sit or stand on the machine. • Always fully secure the machine to the towing vehicle hitch before towing. • Use caution when towing. Tow with an appropriate vehicle, and avoid slopes, ditches etc. Refer to the towing vehicle owner's manual for correct safety and towing instructions. • Do NOT tow on public roads.

HDS800 / HPS800

1. If required, lower the hydraulic ram assembly. Ensure the ram assembly is held securely before proceeding.

2. Place the tow ball socket over the towing vehicle tow ball and secure it. Rotate the jockey wheel (A) height adjustor (B) to raise/lower the tow ball socket a needed.

3. Raise the jockey wheel:

a. Pull out and hold the spring-loaded release pin (C).
b. Whilst the release pin is in the unlocked position, swing the jockey wheel up to the horizontal position, then release the pin, ensuring that is fully enters its horizontal position locating hole.

1. Connect the trailer electrical connection to the towing vehicle and ensure that the trailer lamps operate correctly.

HPS500

1. Raise the front support leg and secure it in the towing position:

a. Unlock the front support leg (A) by removing the locking pin (B).
b. Swing the leg up to the horizontal towing arm position, then secure it with the locking pin.

1. Hitch the towing arm securely to the towing vehicle, then place the hitch pin in the locked position.

Maintenance

Running combustion engines in confined areas CAN KILL IN MINUTES. Engine exhaust fumes contain carbon-monoxide – a deadly gas that you cannot smell or see. NEVER run a combustion engine in confined areas EVEN IF windows and doors are open. ONLY run combustion engines OUTDOORS and away from doors, windows and vents. Petrol / fuel / gasoline is extremely flammable – keep clear of naked flames or other ignition sources. Do not have the engine running during inspection and maintenance unless specifically required. • The engine should be cool enough to touch before performing maintenance activities. • Some maintenance activities may be beyond the scope of some users. Do NOT attempt procedures that you are not comfortable with, or do not have the necessary tools, experience or knowledge for – take the unit to an authorised service centre or qualified technician for servicing. • Harsh operating environments such as extreme temperatures, dust etc may necessitate more frequent maintenance. • Failure to follow the maintenance schedule, using incorrect or non-compatible accessories or replacements parts, or general negligence may result in making the product warranty void.

To keep the machine performing at optimal efficiency, regular checks and maintenance is required. The maintenance schedule below specifies preventative maintenance checks and necessary maintenance tasks and how often they should be performed. The schedule applies to multiple engines; some engines may not include some components, so maintenance on those components is not applicable.

Maintenance Schedule

Use the following maintenance schedule for a list of regular maintenance tasks and how often they need to be performed. Maintenance frequency is based on average usage. Be aware of how much the machine is used and be sure to follow the schedule according to time or usage, whichever comes first.

Towards the end of this document is a form you can use for maintenance record keeping. It is recommended that you keep a reference of all maintenance.

Major Servicing and "Heavy-Duty" Usage - For engines that are subject to "heavy-duty" use, which can be defined as being used under loads of 85% or more and / or in use more than

approximately 300 hours per year (for example, generators and water pumps), more frequent "Major Service" maintenance is required. In addition to normal service requirements, and as with many smaller machine and off-road bike engines, the following parts (as applicable for petrol, diesel or 2-stroke engines) may require replacement during a major service:

- Piston rings.

• Big-end bearings.

- Small-end bearings.

• Gudgeon pin.

- Oil rings.

• Gaskets and seals.

- Valve seats.

Inspection of the following items is required:

- Piston for cracks and stress fractures.

• Bore for wear requiring reconditioning.

• Full machine for broken, worn or loose parts.

Failure to follow the maintenance schedule, using incorrect or non-compatible accessories or replacements parts, or general negligence may result in making the product warranty void.

Hydraulic System

Very high fluid pressure and temperatures are created in the hydraulic system. Hydraulic fluid will escape through the smallest opening and can puncture skin and cause severe injury and blood poisoning. Never check for leaks with your hands or any other body part while the hydraulic system is pressurised – use a piece of wood or other hard material that any leak will be visible on. Seek medical attention immediately if injured by hydraulic fluid. • Before performing any maintenance, relieve any hydraulic pressure – with the engine OFF, use the ram control lever to move the ram forward and back until it no longer moves (the pressure is released). • If any hydraulic system components are damaged or show signs of wear, replace them before using the machine. Do NOT remove the hydraulic oil fill cap when the system is pressurised, the engine is running or the oil is hot. • Always check the oil level before using the machine and ensure it is at or close to the recommended level. • Oil should be replaced approximately every 200 hours of machine use or if it has a milky or cloudy appearance, which indicates that it has absorbed considerable moisture. Before changing oil, ensure that it is cool enough to not cause burns. • Suitable hydraulic oil is 10W AW-32, ASLE H-150, or ISO 32. • Before first use, add and hydraulic oil and double-check oil level.

• Before each use, check all hydraulic hoses, connections and fittings for signs of wear or damage or leaks. Ensure all hydraulic connections and fittings are secure.
• Lubricate the hydraulic ram slide (A) and edges with grease before each use and ensure it is clean and free of debris after each use.

Checking and Changing Hydraulic Oil – HDS800 / HPS800

Close-up of a red mechanical component with a labeled point A pointing to a specific area (no text or symbols on the object itself)

Check oil temperature from the sight glass at the rear of the hydraulic oil tank – the temperature is indicated by the height of the red mercury column with regard to the scales on the glass.

To check hydraulic oil level:

1. Place the machine on a flat and level surface.
2. View the oil level using the oil sight glass on the back of the hydraulic oil tank. Note that the scale on the sight glass refers to oil temperature, not level.
3. Ensure that the oil level is at approximately 70 to 80% full. If the oil level is low, add additional oil until the correct level is reached. If the oil level is too high, drain some oil until the correct level is reached.

To change the hydraulic oil:

1. Place the machine on a suitable surface that is flat and level and have a container ready to catch drained oil.
2. Unscrew (rotate left) and remove the drain plug (A) and washer from the underside of the hydraulic oil tank.

3. When all oil is drained, clean the drain plug and washer and then reinstall them. Screw in fully (rotate right) and firmly tighten.

4. Remove (rotate left) the oil filler cap (B) from the top of the hydraulic oil tank.

5. Using a funnel, carefully add oil to the hydraulic oil tank until the recommended level is reached (approximately 20 litres). Double-check the oil level.

6. When finished, re-install (rotate right) the oil filler cap until firm. Wipe off any residual oil from the machine.

1. Start the engine and extend and retract the ram several times to remove any air from the hoses.

Checking and Changing Hydraulic Oil – HPS500

To check hydraulic oil level:

1. Place the machine on a flat and level surface.
2. Unscrew the oil filler cap/dipstick (A) and check how far up the dipstick oil can be seen. Note that the oil filler cap/dipstick must be fully screwed in for a correct oil level reading.
3. Ensure that the oil level is at approximately 70 to 80% full; that is, the oil level up approximately 34 the length of the dipstick. If the oil level is low, add additional oil until the correct level is reached. If the oil level is too high, drain some oil until the correct level is reached.

To change the hydraulic oil:

1. Place the machine on a suitable surface that is flat and level and have a container ready to catch drained oil.
2. Disconnect (rotate left) the high-pressure hose (B) at the rear of the machine and allow oil to drain from the tank and hose. Be careful not to lose the O-ring in the connector.
3. When all oil is drained, clean the hose connections and O-ring and then reinstall them. Screw the connector in fully (rotate right) and firmly tighten.
4. Remove (rotate left) the oil filler cap (A) from the top of the hydraulic oil tank.
5. Using a funnel, carefully add oil to the hydraulic oil tank until the recommended level is reached (approximately 5 litres). Double-check the oil level.
6. When finished, re-install (rotate right) the oil filler cap until firm. Wipe off any residual oil from the machine.
7. Start the engine and extend and retract the ram several times to remove any air from the hoses.

Engine Oil

Engines are NOT supplied with engine oil, although traces of oil from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the

engine before use. Failure to add engine oil will void the product warranty. • Always check engine oil level when the machine is in an upright position on a flat and level surface. • Do not use used or contaminated engine oils. • Use only engine oils of the correct type (see Specifications). • Perform the first oil change within the first 20 hours of use. Subsequently, change the oil every 20 hours of use. • It is recommended that the engine be warm, but not hot, when performing oil changes. When the oil is warm it drains faster. • Using dirty or incorrect engine oil may cause engine damage and void any warranty • Always use suitable tools. • Always dispose of used oil in an environmentally responsible manner and according to regulations. • Some engines feature oil level detection, which will prevent the engine being started or automatically stop a running engine if there is insufficient oil. • Always check the oil level and ensure is at or near the "MAX" indicator before using the machine. • Some models may have 2 oil drain plugs and fillers on either side of the engine – it does not matter which one is used.

4-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe or irreparable damage may occur if the engine is allowed to run without engine oil. The engine oil level requires regular maintenance as per the maintenance schedule.

Checking and Changing Engine Oil

To check engine oil level:

1. Place the machine on a flat and level surface.

2. Clean the machine around the oil filler cap (A) so that no dirt or other material enters the engine when the cap is removed.

3. Remove the oil filler cap (rotate left) until fully unscrewed. For machines without a dipstick, the oil level is determined by how close the oil is to the edge of the filler hole (B). For machines equipped with an oil level dipstick:

a. Remove the dipstick (C) and wipe clean with a piece of cloth or paper.
b. Insert the dipstick into the oil filler but do not screw it in.

c. Remove and inspect the dipstick – the oil level is determined by where oil can be seen on it.

1. Ensure that the oil level is at or just under the "maximum". If the oil level is low, add additional oil until the correct level is reached. If the oil level is too high, drain some oil until the correct level is reached.

2. When finished, re-install (rotate right) the oil filler cap until firm. Wipe off any residual oil from the machine.

To change the engine oil:

1. Place the machine on a suitable work surface that is flat and level and have a container ready to catch drained oil.
2. Clean the machine around the oil drain plug (D) and oil filler cap/dipstick so that no dirt or other material enters the engine when the plug or cap is removed.
3. Unscrew (rotate left) and remove the drain plug and washer.
4. Tilt the machine and drain all oil from the engine. Once drained, allow the machine to sit level again.
5. Clean the drain plug and washer and then reinstall them. Screw in fully (rotate right) and firmly tighten.
6. Remove the oil filler cap (rotate left) until fully unscrewed. Wipe the oil level indicator clean with a piece of cloth or paper.
7. Using a funnel, carefully add oil to the engine until the "maximum" level is reached. Double-check the oil level (described above).
8. When finished, re-install (rotate right) the oil filler cap until firm. Wipe off any residual oil from the machine.

Air Filter

Operating the machine without a functional air filter may cause severe engine damage and will void any warranty. • A dirty or oil saturated air filter will restrict air flow, which can be mistaken as fuel

system problems. Check the condition of the air filter before adjusting engine idle speed, where applicable. • If the air filter is damaged (torn, broken, disintegrating), replace it.

The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal damage to it. The air filter requires regular maintenance as per the maintenance schedule.

Inspection and Cleaning

Inspect the air filter for dirtiness and debris, damage etc. Clean or replace the filter element as necessary. To clean air filters:

• For foam filters, wash the filter in warm water and mild detergent, then rinse and allow to dry.
• For paper filters, use compressed air to blow particles from it. The air should be blown from the engine side of the filter.
• Clean all other air filter assembly components using water and mild detergent, then dry them.
• For foam filters, place a few drops of clean engine oil on the filter then squeeze it a few times to spread the oil through the filter material and remove any excess oil.

Removal/Installation – Petrol Engines

To remove the air filter:

1. Unscrew (rotate left) the wing nut (B) securing the air filter cover (C) and remove the cover from the air intake assembly (A).
2. Unscrew (rotate left) the wing nut (D) and remove the filter element (E).

Spark Plug

If the spark plug is damaged (cracked insulator, broken or eroded electrodes etc), replace it. • Always use spark plugs of the correct "heat range" - see Specifications. Spark plug maintenance is applicable to diesel engines.

The spark plug is used to ignite the air/fuel mixture inside the engine. The spark plug has electrodes on one end and an electrical terminal on the other. The spark plug requires regular maintenance.

Cleaning and Gap Checking

The spark plug should be checked and cleaned as per the maintenance schedule.

1. Remove any carbon deposits on the spark plug (A) electrodes (B) with a wire brush.
2. Clean the spark plug threads and the electrical terminal (C) on the top.

To check and adjust the spark plug "gap":

1. Use "feeler" or "thickness" gauges (X) to measure the existing gap. The gauge must drag a little when being slid between the electrodes (2) – this means the measurement is fairly accurate.
2. Adjust the gap to within specification (see Specifications). If the gap needs to be reduced, gently tap the electrode as required. If the gap needs to be increased, use pliers to gently pull the electrode as required.
3. Measure the gap again and ensure it is within the specified range before re-installing the spark plug.

Removal/Installation

1. Pull the electrical lead (B) from the terminal on top of the spark plug (A).
2. Clean the area around the spark plug so that no dirt or other material can enter the engine when the spark plug is removed.
3. Use the spark plug tool (C) to remove the spark plug (rotate left).

To re-install the spark plug:

1. Place the spark plug in its hole and screw it in (rotate right) until "finger tight".
2. Use the spark plug tool to tighten the spark plug approximately one quarter turn (do not over-tighten).
3. Place the electrical lead over the spark plug terminal and push it down so that it connects firmly with the terminal

Transportation and Storage

Always ensure that the machine is cool enough to touch before transporting or storing. • Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or

other ignition sources. • Always transport the machine with the fuel tap and engine ON/OFF switch in the "OFF" position. • Drain the fuel tank before transportation or storage.

Preparing for Transport and Storage

• Clean the machine down by removing debris, dirt etc before storing it.
• Drain the fuel system. It is advised to have the fuel tank as empty as possible before draining.

a. Place the fuel tap in the "OFF" position.
b. Unscrew (rotate left) the carburettor drain plug. Use a suitable container to catch the draining fuel.
c. Place the fuel tap in the "ON" position and allow the fuel to drain. Store the drained fuel in a properly sealed container.
d. Place the fuel tap in the "OFF" position.
e. Re-install (rotate right) the carburettor drain plug and tighten.

• Lightly lubricate all machine surfaces and moving parts to prevent corrosion.
- Store the unit in a dry, well-ventilated area and out of the reach of children.

Long Term Storage

Follow the normal procedures for storage, then:

• Remove the spark plug and pour 10ml of clean engine oil into the cylinder. Pull the starter cord slowly to distribute the oil. Re-install the spark plug.
  • Cover the equipment to protect it.

Troubleshooting

Running combustion engines in confined areas CAN KILL IN MINUTES. Engine exhaust fumes contain carbon-monoxide – a deadly gas that you cannot smell or see. NEVER run a combustion engine in confined areas EVEN IF windows and doors are open. ONLY run combustion engines OUTDOORS and away from doors, windows and vents.

Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other ignition

sources. • The product is NOT supplied with engine oil, although traces of oil from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the engine before use – see Engine Oil. Failure to add engine oil will void the product warranty. • Do not have the engine running during inspection and maintenance unless specifically required. • The engine should be cool enough to touch before performing maintenance activities. • Some maintenance activities may be beyond the scope of some users. Do NOT attempt procedures that you are not comfortable with, or do not have the necessary tools, experience or knowledge for – take the unit to an authorised service centre or qualified technician for servicing.

The following information may assist in identifying a problem and rectifying it.

Difficulty starting the engine.

Possible Fault	Action
Lack of fuel	Check that there is fuel in the tank and the fuel tap is in the "ON" position. • To further check if fuel is reaching the carburettor, remove the carburettor drain plug and check if fuel drains.
Engine "OFF"	Ensure engine ON/OFF switch is in the "ON" position.
Carbon build-up on spark plug	Remove the spark plug and clean any carbon from the electrodes before re-installing it. Not applicable to diesel engines.
Spark plug faulty	Remove the spark plug, then reconnect the plug lead to it. Place fuel tap in the "OFF" position and the engine ON/OFF switch in "ON" position. Touch the spark plug electrode to a part of the engine crankcase, away from the spark plug hole, and attempt to start the engine – a spark should be visible across the electrodes as the engine is rotated. If no spark is visible, replace the spark plug. Not applicable to diesel engines.
Engine "flooded" with fuel	Place the choke in "HOT" or "RUN" position. Leave the ON/OFF switch in the "OFF" position. Pull the starter cord several times to assist clearing excess fuel from engine before attempting to start engine.
Not enough or too much engine oil	Check oil level and ensure that the level is at or just below the recommended maximum level.

Engine starts but does not idle.

Possible Fault	Action
Blocked air filter	Perform anair filter service.
Idle speed requires adjustment	Adjust idle speed until engine runs smoothly and at a reasonable speed when idling. For fuel-injected models, idle speed adjustment should not be required.

Difficulty restarting the engine after use or engine stops suddenly during use.

Possible Fault	Action
No fuel or engine oil	Check fuel level and ensure adequate fuel is available. For some engines, an engine oil sensor will automatically switch off the engine or prevent starting if a low engine oil level is detected.
Overheating	Allow engine to cool before restarting. If possible, improve engine cooling, such as operating in lower temperatures.
Carbon build-up on spark plug	Perform a sparkplug service. Not applicable to diesel engines.
