• SET the choke lever to the “START” position.

•

Left hand SQUEEZING the throttle trigger.

Right hand PULL the starter rope with a quick firm and consistent upward motion until the engine fires or starts and runs.

Note: If difficulties with starting are experienced (this may occur in colder conditions) refer to troubleshooting section in this manual.

•

Move the choke lever to “RUN” position.

Allow engine to warm up for 5-20 seconds.

MIXING THE FUEL (Fig. 3)

• This product is powered by a 2-stroke engine and requires pre-mixing petrol and 2-stroke oil. Pre-mix unleaded petrol and

2-stroke engine oil in a clean container approved for petrol.

• This engine is certified lo operate on unleaded petrol intended for automotive use with an octane rating of 90 {[R + M] / 2) or higher.

• Do not use any type of pre-mixed petrol fall from fuel service stations, this includes the pre-mixed petrol I oil intended for use in mopeds, motorcycles, etc.

• Use synthetic 2-stroke oil only. Do not use automotive all or

2-stroke outboard all.

• Mix 2% synthetic 2-stroke oil into the petrol. This is a 50:1 ratio.

• Mix the fuel thoroughly and also each time before fueling.

• Mix in small quantities. Do not mix quantities larger than usable in a 30 day period. Synthetic 2-stroke oil containing a fuel stabilizer is recommended.

To start a warm engine:

With the engine switch on “RUN” position, PULL the starter rope with a quick firm and consistent upward motion until the engine starts.

To slop the engine:

OPERATING THE TRIMMER

Hold the trimmer with the right hand on the rear handle and the left hand on the front handle. Keep a firm grip with both hands while in operation. Trimmer should be held at a comfortable position with the rear handle about hip height.

Always operate trimmer at full throttle. Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and bump head which may cause damage from overheating. If grass becomes wrapped around the bump head, stop the engine, disconnect the spark plug wire, and remove the grass. Prolonged cutting at partial throttle will result in oil dripping from the silencer.

FILLING THE TANK

• Clean surface around fuel cap to prevent contamination.

• Loosen fuel cap slowly to release pressure and to keep fuel from escaping around the cap.

• Carefully pour fuel mixture into the tank. Avoid spillage.

• Prior to replacing the fuel cap, clean and inspect the gasket.

• Immediately replace fuel cap end hand lighten.

• Wipe up any fuel spillage. Move 9m away from refuelling site before starting engine.

NOTE: It is normal for smoke to be emitted from a new engine during and after first use.

WARNING

Always shut off engine before fuelling. Never add fuel to a machine with a running or hot engine. Move at least gm from refuelling site before starling engine. Do not smoke!

Maintenance

WARNING

Use only original manufacturer’s replacement parts, accessories and attachments. Failure to do so can cause possible injury, poor performance and may void your warranty.

• You may make adjustments and repairs described here. For other repairs, have the trimmer serviced by an authorised service agent.

• Consequences of improper maintenance may include excess carbon deposits resulting in loss of performance and discharge of black oily residue dripping from the muffler.

• Make sure all guards, straps, deflectors and handles are properly and securely attached to avoid the risk of personal injury.

CLEANING THE EXHAUST PORT AND MUFFLER

Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port and muffler may become blocked with carbon deposits. If you notice a power loss with your petrol powered tool, a qualified service technician will need to remove these deposits to restore performance.

SPARK ARRESTOR

This machine is fitted with a spark arrestor to help prevent fires. The spark arrestor is fitted at the muffler discharging port. To ensure proper performance of your product, tile spark arrestor must be cleaned or replaced every 25 hours or each year. Please contact your nearest service dealer for a new spark arrestor. To find your nearest service dealer please visit our website.

CLEANING AIR FILTER

A dirty air filter will cause starting difficulty, loss of performance, and shorten the life span of the engine. Check the air filter monthly. For best performance, replace the air filter at least once a year.

• Loosen the air filter cover by turning the fixing knob counter clockwise.

• Remove the airbox cover and the air filter

• Clean the foam filter element with warm soapy water. Rinse and let dry.

NOTE: If the foam filter element is damaged, it should be replaced.

• Apply a light coat of engine oil to the roam filter element, then squeeze it out.

• Reinstall the air filter.

NOTE: Make sure the filter is seated properly inside the cover.

Installing the filter incorrectly will allow dirt to enter the engine, causing rapid engine wear.

• Reinstall the airbox cover and tighten the fixing knob to secure.

FUEL TANK

WARNING

A leaking fuel cap is a fire hazard and must be replaced immediately.

The fuel cap contains a sealing gasket and a check valve to ventilate built up fuel gasses. A clogged check valve will cause poor engine performance. If performance improves when the fuel cap is loosened, the check valve may be faulty. Replace fuel cap if required.

The fuel supplied to the engine is passed through a filler to remove any contaminants from entering the engine.

Contaminants in the fuel can cause poor performance and damage to the engine.

The fuel filter is a non-serviceable item and if needed should be replaced by an AUTHORISED SERVICE CENTRE.

SPARK PLUG REPLACEMENT (Fig. 9)

This engine uses an NGK BPMR7A spark plug with 0.5mm electrode gap. Use an exact replacement and replace annually.

IDLE SPEED ADJUSTMENT (Flg.10)

If idle speed is too high and needs adjustment, turn the idle speed screw counterclockwise to reduce the engine speed.

If the idle speed is too low and needs adjustment, turn the idle speed screw clockwise to increase engine speed.

NOTE: The engine should be at normal operating temperature before making adjustments to the idle speed.

STORING THE PRODUCT
