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.

Adequately fill the fuel tank with the correct fuel type.

• Use non-ethanol unleaded mixed at a 30:1 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.

To fill or top up fuel:

1. Place the machine in a horizontal position with the fuel filler cap facing up 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.

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 may also be visible in the fuel intake tube.

Engine Starting and Hedge Trimmer Operation

Starting the Engine

1. PRIME – If necessary, "prime" the fuel system.

2. CHOKE – If the engine is cold, place the choke (B) in the "COLD" position. If the engine is warm or the ambient temperature is high, place the choke in the "RUN" position.

3. IGNITION – Slide the engine ON/OFF switch (C) away from the "STOP" position.

4. START – Slowly pull out the starter cord (D) 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 (B) 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 "STOP" 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.

Hedge Trimmer Operation

Before use, ensure that there are no electrical cables or unseen hazards in the work area. •

Do not use the machine if the cutting blades are damaged or blunt. • Always hold the machine firmly using both hands and machine handles. • Always maintain sure footing and do not attempt to over-reach. • Do not attempt to cut through material that is over 10mm (3/8") diameter or too tough for the machine / cutting blades. • Clean and lubricate the cutting blades after every use.

The machine is used for trimming hedges and shrubs. Note the following:

• Adjust how quickly you move the blade across the hedge according to the hedge density. A sweeping,

circular motion when cutting generally provides acceptable results.

• Use a string-line to create straight hedging – pull the string taught between the start and end of the

hedging and use this as a guide for where to cut to.

• It is recommended to trim the sides of hedges so that the top of the hedge is lightly narrower than the

bottom – this helps promote more even growth.

Using the Throttle

The throttle (E) is used to adjust the engine speed, which in turns controls blade engagement and speed. To adjust the throttle, grip the handle (F) so that the throttle safety switch (G) is pushed in – this allows the throttle to be adjusted – squeeze to increase engine speed. Note the following:

• The throttle safety switch must be pushed in to adjust the

throttle. When the throttle safety switch is released it is no longer possible to adjust the throttle.

• It is recommended to use the machine at full throttle. The

machine requires a minimum engine speed for the internal clutch to engage and begin reciprocating the cutting blades.

Rotating the Handle

The handle can be rotated 90° to either the left or right, from the central position. This is to assist in trimming hedge sides etc and helps reduce fatigue. To rotate the handle, push down and hold the handle rotation lock (H) then rotate the handle in the required direction until it "clicks" into 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 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

maximum use of approximately 300 hours per year. Apply common-sense when following the maintenance

schedule based on your actual use of the product. • Keep reasonable records of maintenance activities for

reference. 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.

Checking, Cleaning or Replacing the 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:

Checking, Cleaning or Replacing the 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 with the fuel filler cap facing up on a flat and level surface.

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 fuel 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 fuel strainer:

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

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

Maintaining the 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.

3. 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.

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.

Greasing the Gearbox

The gearbox is used to activate the cutting blades. The gearbox internals operate at high speed and requires lubrication. It is recommended to grease the gearbox approximately every 6 months, possibly more frequently if used often. A grease gun and grease is required – normal automotive wheel bearing grease is suitable. To grease the gearbox:

1. Place the machine in a horizontal position on a flat and level surface.

2. Attach the grease gun hose to the nipple (A) under the engine and inject one squeeze of grease.

Cleaning and Lubricating the Blades

The cutting blades must be cleaned and lubricated after every use. Failure to do so will reduce

cutting performance and may also cause the blades to seize and damage the machine. Faults or

failure resulting from not maintaining the cutting blades correctly is not covered under warranty.

1. Place the machine in a horizontal position on a flat and level surface.

2. Use a non-metallic brush to remove debris from all surfaces of the cutting blades. Wipe away any sap

etc from all blade surfaces and ensure the blades are dry.

3. Spray the cutting blades with spray lubricant or wipe down with light machine oil.

4. Keep the blades protected using the blade sheath.
