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.

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 Checking, Cleaning and Replacing the 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. • Always pre-mix the fuel before

placing it in the fuel tank.

Adequately fill the fuel tank with the correct fuel type.

- Use non-ethanol unleaded mixed at a 25:1 ratio with 2-stroke engine oil (higher RON values and good quality 2-stroke oil will provide best engine performance). Do not use old or contaminated fuel/oil. Fuel/oil mix ratio examples are shown below.

Petrol (Litre)	1	2	5	10		Gas (US Gal)	0.5	1	2	3
Oil (Millilitre)	40	80	200	400		Oil (Fl. Oz)	2.56	5.12	10.24	15.36

1. Place the machine in a horizontal position on a flat and level surface with the fuel filler cap facing up.
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 machine away from the spillage before starting the engine.

Priming the Fuel System

When an engine is new or has been completely run out of fuel it may be necessary to "prime" the fuel system before attempting to start the engine. This means removing any air from the fuel line. To prime:

1. Ensure the fuel tank is filled with fuel.
2. Press the fuel primer (A) bulb repeatedly until you feel resistance or pressure in the bulb – this indicates that it is full of fuel. Fuel will also be visible in the fuel intake tube.

Attaching the Piling Socket Adaptor

Do not use the machine without a piling socket adaptor attached.

Screw the required piling socket adaptor (1) to the thread on the end of the hammer case (B) (rotate right) and firmly tighten by hand.

Engine Starting and Stopping

Starting the Engine

1. PRIME – If necessary, "prime" the fuel system.
2. CHOKE – If the engine is cold, place the choke (E) in the "COLD" position. If the engine is warm or the ambient temperature is high, place the choke in the "RUN" position.
3. IGNITION – Place the engine ON/OFF switch (F) in the "ON" ("I") position.
4. START – Slowly pull out the starter cord (G) until you feel it engage with the engine, then pull it out rapidly. The engine should start. Allow the starter cord to rewind slowly – do not let it "snap" back.
5. WARM-UP – Allow the engine to warm-up and run smoothly. If choke is being applied, gradually move the choke (E) to the "RUN" position.

If the engine does not start, repeat step 4 onward. If the engine fails to start after several attempts, refer to Troubleshooting.

Stopping the Engine

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

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.

Post Driver Operation

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 driving posts. Do not attempt to drive posts into set concrete, rock, tree roots, or other extremely hard surfaces. • Do not use the machine without a piling socket attached.

The machine is used for driving "star pickets" and hollow metal posts etc into the ground. For example, to erect simple fencing etc. The machine operates by driving a "hammer" against the top of the post many times per second, effectively forcing it into the ground. The machine is designed for manual operation, where the operator both holds and controls it. Note the following:

• Place the post/star picket into the required position before driving it.
• Adjust the throttle, which controls the hammer action, only when ready to begin driving the post.
• Hold the machine as straight as possible when in use to ensure that posts are driven in vertically.

To drive a post:

1. Start the machine and allow it to warm up.
2. Position the post in the required location.
3. Place the machine over the post so that it rests on it.
4. Adjust the throttle for the desired hammering speed.
5. Drive the post into the ground as required – there is no need to push down on the machine.
6. Release the throttle – this disengages the hammer action.
7. Lift the machine from the post.

Using the Throttle and Adjusting Hammer Speed

The throttle (H) is used to adjust the engine speed, which in turns controls speed of the hammer action. To adjust the throttle, grip the throttle handle (I) so that the throttle safety switch (J) is pushed in – this allows the throttle to be adjusted – squeeze to increase engine speed. The throttle features a limiting screw (K) that stops it from being opened further. Note the following:

• The throttle safety switch must be pushed in, in order to adjust the throttle. When the throttle safety switch is released it is no longer possible to adjust the throttle.
• It is recommended to set the limiting screw when an effective engine/hammer speed is attained. Turn the screw right to reduce the throttle opening limit (slower speed). Turn the screw left to increase the throttle opening limit (faster speed). The hardness of the material that the posts are being driven into may require adjustment of engine/hammer speed for best performance.

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 described may be beyond the scope of some users. For procedures that you are not comfortable with or have the tools or experience for, have the unit serviced by a service centre or qualified technician.

To keep the engine performing at optimal efficiency, regular checks and maintenance is required. Proper care and maintenance ensures best performance and longest service life.

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.

Harsh operating environments such as extreme temperatures, dust etc may necessitate more frequent maintenance. • Maintenance frequencies are based on general factors including a m use of approximately 300 hours per year. Apply common-sense when following the maintenance be based on your actual use of the product. • Keep reasonable records of maintenance activities for ce. Failure to follow the maintenance schedule, using incorrect or non-compatible accessories placements parts, or general negligence may result in making the product warranty void.

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 reduce performance

and 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 engine breather may be connected to the air intake assembly – this may lead to a build-up of oil in the air filter over extended use and is normal. The air filter requires regular maintenance as per the maintenance schedule.

Air Filter 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.

Air Filter Removal/Installation

To remove the air filter:

1. Place the machine in an upright position on a flat and level surface.
2. Unscrew the air filter cover screw (B) (rotate left) until the air filter cover (A) can be removed.
3. Pull the air filter element (C) from the air intake assembly.

To install the air filter:

1. Insert the air filter element into the air intake assembly.
2. Re-install the air filter cover and secure it with the air filter cover screw (rotate right).

Fuel Strainer

A dirty or blocked fuel strainer will restrict fuel flow, which can reduce performance and be mistaken as fuel system problems. Check the condition of the fuel strainer before adjusting engine idle speed,

where applicable. • If the fuel strainer is no longer serviceable, replace it.

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

Fuel Strainer Inspection and Cleaning

Inspect the fuel strainer for dirtiness and debris etc. Clean or replace the strainer as necessary. To clean fuel strainers:

• Wash the strainer in clean solvent.
• If possible, use compressed air to assist in removing any blockages. Blow air into the strainer from where it connects to the tube.

Fuel Strainer Removal/Installation

To remove the fuel strainer:

1. Place the machine in a horizontal position on a flat and level surface with the fuel filler cap facing up.
2. Remove the fuel tank cap (rotate left) and empty the fuel tank (A).
3. Use a hooked object to capture the fuel intake tube (B) inside the fuel tank and gently pull it from the tank.

4. The strainer (C) is installed on the end of the tube – to remove it, twist and pull it from the end of the tube. To install the strainer:

5. Firmly push the strainer onto the fuel intake tube.

6. Place the tube back inside the fuel tank – it should rest along the bottom of the tank.

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.

Spark Plug 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.

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.

Engine Tuning Guidelines

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. • 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. • Improper tuning can lead to engine failure – engine failure due to improper tuning is not covered under warranty. • If you cannot tune the engine, contact an authorised service centre for assistance or have the machine checked by a small engine specialist. • The carburettor is supplied factory-set and should run properly. Engine tuning should be attempted only if the machine shows signs of requiring adjustment. • A tachometer is recommended for setting engine idle and full throttle speeds.

The engine must be maintained in a reasonable "state of tune" to ensure best performance and safety. If the engine is running roughly, emitting excessive smoke, not revving properly, not idling properly, showing signs of reduced power, not responding crisply to the throttle etc, it may require "tuning". Basic tuning for 2-stroke engines is not difficult, however, care should be taken in understanding the tuning process and learning how to recognise the symptoms for when engine tuning is required and where and how to make adjustments. Note that factors such as altitude, fuel mixture, ambient temperature etc may all affect engine running characteristics. There are two basic engine conditions that determine improper tune:

• Rich - An adjustment that is too rich will cause the engine to smoke, have insufficient power, result in additional carbon build up and may damage the engine. The proportion of fuel in the air/fuel mixture is so high that the fuel does not burn well. The partially burned mixture is expelled into the exhaust and exits the engine as smoke. Carbon build-up may affect the performance of the spark arrestor (if equipped) and cylinder ports if run for a period of time. Outside of carburetor adjustments this can also be caused by having too much oil mixed with the fuel, and/or old fuel.
• Lean - An adjustment that is too lean will also cause the engine to have insufficient power and is more likely to damage the engine than a rich mixture. The proportion of fuel in the air/fuel mixture is so low that there is not enough fuel to burn. Lean running causes the cylinder temperature to rise, which often leads to engine seizure, and for excessive revving which may result in connecting rod bearing failure. Other causes for a lean running condition include lack of oil in the fuel mix, and when the fuel tank runs empty.

Before any engine tuning:

• Service the air filter.
• Service the spark plug.
- Use fresh fuel.

Carburettor Adjustments

The carburettor has 3 adjustments available:

• Idle Speed – Controls how open the throttle is when the throttle is released. If idle speed is set too low, the engine will stop when the throttle is released due to a lack of air/fuel mixture. If idle speed is set too high, the engine will run when the throttle is released, however, at a speed that will engage the clutch and cause the hammer action to activate – this is a dangerous condition that should never be allowed.
• Low Speed Mixture – Controls the proportion of fuel in the air/fuel mixture at idle speed. If the low speed mixture is too rich, the engine will load up when idling and then stop. If the low speed mixture is too lean, the engine will race or surge when idling and then stop.
• High Speed Mixture – Controls the proportion of fuel in the air/fuel mixture at working speed. If the high speed mixture is too rich, the engine may not reach the speed necessary for maximum power, emit excessive smoke and respond poorly to throttle movement. If the high speed mixture is too lean, the

engine may reach speeds where bearing failure and piston seizure are likely. It will also lack power and tend to run very hot.

The adjustment screws are generally located on the starter cord side of the unit. The high speed and low speed mixture screws are general marked "L" and "H", respectively. In the adjacent image, idle speed is (A), low speed mixture is (B) and high speed mixture is (C).

Factory Settings

Each adjustment screw has a general "factory setting", which is measured from the adjustment screw being rotated "IN" (right / clockwise) until fully seated (but not tight). From this point, the setting is made by counting the number of full rotations of the screw "OUT" (rotate left / anti-clockwise). Factory settings are:

• Idle Speed – Approximately 5 turns out.
• Low Speed Mixture – Approximately 2.5 turn out.
  • High Speed Mixture – Approximately 2 turns out.

Use the factory settings as the basis for tuning. Set all adjustment screws to factory settings, then test the engine before further tuning. Use a suitable flat-blade screwdriver and ensure that the screwdriver is properly engaged with the adjustment screw before rotating.

Tuning

1. Start and allow the engine to idle uintil it is warmed up – tuning a cold engine will result in rich running when the engine is warm. If the engine does not idle, use the throttle to keep the engine running ("blip" the throttle; do not run the engine continuously at high speed).
2. Adjust Idle Speed – Rotate the adjustment screw one quarter ( 14 ) turn at a time – rotate "IN" (right / clockwise) to increase idle speed; rotate "OUT" (left / anti-clockwise) to reduce idle speed. Set the speed so the engine idles as fast as possible without engaging the clutch. Never set the idle so the driving action activates when the throttle is released. If the engine will not idle, adjust the low speed mixture (step 3).
3. Adjust Low Speed Mixture – Rotate the adjustment screw one quarter ( 14 ) turn at a time – rotate "IN" (right / clockwise) to lean the low speed mixture; rotate "OUT" (left / anti-clockwise) to richen low speed mixture. Rotate the screw IN until the engine begins surging or wants to stop – this is the lean adjustment position. Make a note of the number of rotations of the screw to reach the lean adjustment position. Then, rotate the adjustment screw OUT – the engine should start running better. Keep rotating the screw OUT until the engine starts to load up – this is the rich adjustment position. Make a note of the number of rotations of the screw to reach the rich adjustment position and compare it to the lean adjustment position. Then, rotate the screw IN to a position where the engine idles best – it should be about midway between the rich and lean position settings. At this point, you may have to re-adjust idle speed (step 2).
4. Adjust High Speed Mixture – Rotate the adjustment screw one quarter ( 14 ) turn at a time – rotate "IN" (right / clockwise) to lean the high speed mixture; rotate "OUT" (left / anti-clockwise) to richen high speed mixture. Rotate the screw OUT until the engine begins slowing and running roughly at full throttle. Then, rotate the adjustment screw IN – the engine should start running better. Keep rotating the screw IN until the engine reaches maximum speed. Then, rotate the screw OUT one eighth (1/8) to one quarter ( 14 ) of a turn to richen the air/fuel mixture for engine cooling purposes.

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.
• Avoid exposing the equipment to direct sunlight, particularly during transportation.
• 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:

• Drain the fuel system. It is advised to have the fuel tank as empty as possible before draining.
  a. 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.
  b. 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.
