Before Use Checklist

Ensure that you carry out all procedures below before starting the engine or operating the equipment. All procedures described are generic in nature and slight variations between

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

2 or more persons are required for assembly. • Suitable tools are required for correct assembly. • Check all parts have been supplied and are in good condition before commencing assembly. • Firmly secure all fasteners. • Occasionally, additional fasteners

may come supplied, however, these are not used for this machine configuration.

1. Place the depth adjustment handle (A) over the depth adjustment shaft (B). Ensure that the spring (C) is facing outward.
2. Place a M8 washer (D) in position, and insert a M8x25 bolt (E) through the slot in the handle and screw it in (rotate right) to the depth adjustment shaft approximately 10mm. Pull the end of the spring over the bolt, then screw the bolt in further (there is no need to "tighten" the bolt as the spring tension should prevent it from loosening).

1. Slide the end of the chain arm (F) onto the bar (G) at the front of the machine. Using a suitable spanner and Allen key, back-off (rotate left) the chain tensioning bolts (F1) on either side of the chain arm so they are as far back as possible.

1. The chain and cutting teeth assembly (H) needs to be "split" in order to be installed. Find the removable link (H1) in the chain – it has split pins (H2) to retain the link pins (H3). Remove both split pins (do not damage or discard them), then using a suitable pin punch and hammer, drive 1 link pin through the chain link from the split pin side. Remove 1 nut, spring washer and bolt (H4) from the split pin side of the tooth plate (H5), then remove the link plate (H6) from the split pin side – the chain is now split.

1. Pull the chain around the drive shaft housing underneath the machine (at this stage run the chain next to the drive gear, and ensure that the cutting teeth are facing forward) so the free end of the chain will lie along the top of the chain arm. Lift the chain onto the drive gear so the links engage with the drive gear teeth. Rest the chain on the ridge running the length of the chain arm.
2. Hold the chain in position so it does not roll back around the drive gear, then pull the free end of the chain over the idler gear at the front end of the chain arm. Bring the two ends of the chain together, then drive the previously removed link pin through the chain link so the chain is again joined. Place the link plate over the two link pins, then re-insert the split pins through the link pins. Bend the legs of the split pins around so the pins cannot fall out. Re-insert the previously removed bolt through the tooth plate and link plate, then secure it using a spring washer and nut. Use the spanners to firmly tighten (rotate right) the nut.

1. Using a suitable spanner and Allen key, advance (rotate right) the chain tensioning bolts (F1) on either side of the chain arm to increase tension on the chain. Tension the chain so there is approximately 10 to 20mm of slack in it when you pull it down from the underside of the chain arm at its centre. When tension is correct, tighten the nut (F2) against the welded nut (F3) on both sides.
2. Bring the guide wheel assembly (I) into position next to the chain arm (left side of the machine when standing behind it). Attach the guide wheel assembly to the plate on the chain arm side using 2 M8x25 bolts (E), 4 washers (D), 2 spring washers (J) and 2 nuts (K). The bolts should pass through a washer, plate, guide wheel assembly, washer, spring washer, then nut. Note that it may be necessary to change the chain arm depth position in order to have access to the bolt holes.

1. On the drive cover side, attach the guide wheel assembly using 2 M8x25 bolts (E), 2 washers (D) and 2 spring washers (J). The bolts should pass through a spring washer, washer, guide wheel assembly, then into the plate. Firmly tighten (rotate right) all fasteners using the spanners.

1. Attach the front guard (L) to the mounting plate (M) above the chain arm using 2 M10x50 bolts (N), washers (O) and spring washers (P). The bolts should pass through a spring washer, washer, front guard, then into the plate. Firmly tighten (rotate right) the fasteners using the spanner.

1. Attach the side guard (Q) to the inside of the soil ejection chute (R) using 4 M6x20 bolts (S), washers (T), spring washers (U) and nuts (V). The bolts should pass through a washer, chute, guard, spring washer, then nut. Firmly tighten (rotate right) the fasteners using the spanners.

When assembly is complete, the machine should look similar to below.

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.

- Use non-ethanol unleaded petrol (higher RON values will provide best engine performance). 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.

Greasing Drive Shafts

Components that REQUIRE greasing will have grease nipples. Grease at all places marked in the diagrams below before use. It is recommended to grease applicable components approximately every 3 months, possibly more frequently if used often. Users will require a grease gun and grease - normal automotive wheel bearing grease is suitable. Attach the grease gun hose to the nipple and inject one squeeze of grease.

Grease at all places marked below.

Engine Starting and Stopping

Engine Starting

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) in the "ON" ("I") position, and secondary ON/OFF switch in the "ON" position.

4. THROTTLE – Place the throttle control (D) just off the "SLOW"

position. To move the throttle, press and hold the button at the top of the lever, move it to the required position, then release the button.

1. 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.

1. WARM-UP – Allow the engine to warm-up and run smoothly. If choke is being applied, place the choke (B) in the "HOT" position.

2. 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

Note that there is a secondary engine ON/OFF switch located on the left handlebar. To place it in the ON position, pull the lever and hold in this position, then rotate the metal clip over so it is between the lever and switch housing. Release the lever – the clip should remain in the ON position.

Stopping the Engine

To stop the engine, release the throttle and place the engine ON/OFF switch in the "OFF" position.

Emergency Stopping

To stop the engine in an emergency, pull the secondary ON/OFF switch lever (A), or push the emergency stop button (B) on the end of the handlebar. After using the button, rotate it right (clockwise) until it "pops" up.

Environmental Considerations

Altitude – If the engine is being used in altitudes at or above 1500m (approximately 5000'), adjustments to the carburettor 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 authorized service centre make the necessary carburettor 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 chart to determine the correct engine oil.

Trencher Operation

Trenchers are high-speed, fast-cutting equipment with exposed teeth that can cause serious or fatal injury if not used correctly or without taking proper safety

precautions. It is extremely important that you read and fully understand the information in this section and all other safety warnings / recommendations and usage instructions before using the equipment. • Before use, ensure that there are no electrical cables, gas or water pipes etc or other buried or unseen hazards in the work area. Contact the applicable utility providers for assistance. • The machine should be operated on ground that is suitable for trenching by machine. • Do not attempt to trench through concrete, rock, tree roots, heavy clay or other hard or problematic surfaces. If you come across material that cannot be trenched by the machine, use some other method to remove the material before continuing trenching (for example, a jackhammer etc) • Do not use attachments or accessories beyond those supplied with the machine. • Augers and auger tips are consumable parts, and are not covered under warranty.

The machine is used for digging and clearing narrow trenches, up to 600mm deep, in suitable ground material. The machine is designed for manual operation, where the operator both holds and controls it. Note the following:

• Adjust the throttle, which engages the trenching chain and controls its speed, only when ready to begin trenching.
• Guide the machine as straight as possible when in use to ensure straight trenches.
• Depending on the softness of the ground material and the depth of trench, it may require several passes at greater depths each time to complete the trench.
• Always check the trenching chain and cutting teeth before trenching. Replace any worn or damaged components. Do not use if damaged in any way.
• If the machine is getting "stuck" during trenching, reduce depth and/or investigate other resons such as suitability of the ground material, obstacles etc.
• When moving the machine, disengage the wheel locks, then push down on the handlebars to raise the trenching arm, then move the machine.

To trench:

1. Position the machine in the required location, with the front of the machine at the end of the trench – that is, trenching is performed by moving the machine backwards.
2. Start the machine and allow it to warm up.
3. Set the trenching arm to the required depth. It may be necessary to hold the trenching arm up by putting weight on the handlebar.
4. Engage the wheel locks.
5. Use the throttle to increase engine speed and drive the trenching chain.
6. Holding the handlebar firmly with both hands, carefully lower the trenching arm into the ground, Allow the cutting teeth to "dig in" to the ground material.
7. When the guide wheel contacts the ground the trench is at full depth. Put weight on the handlebar to raise the trenching arm, then disengage the wheel locks and move the machine backwards 100 to 150mm (4 to 6").
8. Repeat steps 4 to 7 as necessary to cut the trench.
9. When finished, stop the engine and raise the trenching arm.

Adjusting Handlebar Position

1. Rotate the locking handle (A) left (anti-clockwise) until the top section of the handle (B) can be rotated.
2. Move the handle to the required position – where it is comfortable for you to hold, and to raise the front of the machine. Generally, waist height is a good starting point.
3. Rotate the locking handle right (clockwise) until the handlebar assembly is firmly held.

Adjusting Trench Depth

1. Pull the depth adjustment handle (C) upward so it disengages from the setting plate (D).
2. Move the handle forward to increase trench depth, or backward to reduce depth as required. Note that it may be necessary to raise the front of the machine off the ground to allow the trenching arm to drop.
3. Release the depth adjustment handle, ensuring that the tab at its bottom is fully engaged in a slot in the setting plate.

Using the Wheel Locks

The wheels use spring-loaded pins to lock them in position while trenching. This is to help reduce forward "creep" caused by the digging action of the cutting teeth.

1. Pull and hold the lever on the right handlebar (E) to disengage the wheel locking pins.
2. Move the machine as required.
3. Release the lever. Note that there may be a small amount of movement before the locking pins fully engage.

The wheel lock mechanism comes factory set, however, can be adjusted, if required (for example, if the locking pins are not fully

disengaging). Before adjusting, visually inspect the wheel lock on each side of the machine – whilst looking at the mechanism, pull the wheel lock lever (E) and check if the locking pin (F) is retracting fully from the

holes in the wheel hub (G). Release the lever – the locking pin should enter the hole in the hub sufficiently to prevent the wheel from rotating. If the cables require adjustment:

• If adjustment is required for one wheel only, loosen the lock nut (H). Rotate the adjusting screw (I) "IN" (right / clockwise) to reduce how much the locking pin retracts when the lever is pulled; rotate "OUT" (left / anti-clockwise) to increase locking pin retraction. When adjustment is complete, tighten the lock nut.
• If adjustment is required equally for both wheels, use spanners to loosen lock nuts (J) at the rear of the machine – there is a second on the inside of the plate (K). Rotate the adjusting screw (L) "IN" (right / clockwise) to reduce how much the locking pins retracts when the lever is pulled; rotate "OUT" (left / anti-clockwise) to increase locking pin retraction. When adjustment is complete, tighten the lock nuts.

Using the Throttle

The throttle lever (F), located on the handlebar column, is used to adjust the engine speed, which in turn engages the trenching chain. To adjust the throttle, press and hold the button at the top of the lever, rotate the lever to the required position, then release the button.

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.

**** Briggs & Stratton "EXi" engines do NOT require engine oil changes; just ensure that oil level is correct.

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.

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.

CHECK OIL WHEN ENGINE LEVEL

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. Tapping the filter element against a hard surface and brushing the pleats using a soft brush may also help remove debris from 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

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).

To install the air filter:

1. Re-install the filter element and ensure it is seated correctly on the air intake assembly.
2. Re-install (rotate right) the wing nut and tighten by hand so that the filter element is secure. Do not over-tighten.
3. Re-install the filter cover and secure it with the wing nut (rotate right). Tighten the nut by hand. Do not over-tighten.

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.

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.

1. 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 (A) from the terminal on top of the spark plug (B).
2. If accessible, 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 engine ON/OFF switch in the "OFF" position.

- Drain the fuel tank before transportation or storage.

Preparing for Transport and Storage

• Drain the fuel system by allowing the engine to run until it stops.
• Ensure the engine ON/OFF switch is in the "OFF" position.
• Ensure the fuel tap is in the "OFF" position.
• Avoid exposing the equipment to direct sunlight, particularly during transportation.
• Remove the tillers (if installed) and install the wheels.
• Ensure the equipment is secure and upright during transport.
• 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:

• Unscrew (rotate left) the carburettor drain plug. Use a suitable container to catch the draining fuel, and allow the fuel to drain. Store the drained fuel in a properly sealed container.
  • Re-install (rotate right) the carburettor drain plug and tighten.
• Remove the spark plug and put 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.
