Prior to use, it is necessary to assemble the safety guard

(3) and cutting spool (1) to the lower shaft (5b) and join the lower shaft (5b) to the upper shaft (5a).

Before assembling the line trimmer, ensure the protective plastic sleeve is removed from the shaft of the trimmer.

Fitting the safety guard


If the Bump Feed knob is fitted, remove the bump feed knob on the end of the spindle prior to fitting the guard.

To remove the bump feed knob, turn the bump knob (18) in an anti-clockwise direction.

1. Slide the safety guard (3) down from the top of the lower shaft (5b), in the orientation shown. Slide it down to the bottom of the shaft (you may need to rotate it to get it past the bend) and locate it over the bracket at the bottom of the shaft.

2. Place the hex nut into the hex shape recess on the guard.

Slide the screw through the side of the safety guard and tighten with the Allen key provided.

Joining the shaft

1. Depress the location pin and insert the lower shaft (5b) into the upper shaft (5a). Rotate the lower shaft until the pin locates positively into the hole in the upper shaft.

2. Tighten the shaft locking knob (21) to secure both shafts in place.

Fitting the spool

1. Slide the raised section of the spool (1) onto the end of the shaft. Ensure the large hex recess on the rear of the spool fits fully over the large hex drive on the base of the spindle.

2. With your fingers, push the spool fully into the housing and screw the bump knob (18) onto the end of the shaft by turning it in a clockwise direction.

Screw the bump knob onto the shaft until it’s tight. Once tight, ensure the bump knob springs back freely when pushed.


Ensure to remove any packing tape from the spool.

3. Once the spool is fully inserted and the lines are fully through the eyelets, pull firmly on each line to disengage the lines from the spool notches. Ensure the lines are fully clear of the spool notches and the line is passing through the eyelets directly to the spool.


Fitting the secondary handle


Before each use, ensure the secondary handle cannot swivel by tightening the secondary handle locking knob. Over time, the knob may vibrate loose.

1. The line trimmer has been pre-packed with the secondary handle facing in the opposite direction to where it must sit during use.

2. Rotate the secondary handle by 180°.

pre-packed position rotate 180º

3. Slide the 6mm x 35mm long hex head bolt through both holes in the underside of the handle. Ensure the hex head of the bolt is fully located in the hex recess in the side of the handle.

4. Fit the small flat washer on the end of the thread and then secure the handle using the yellow knob to tighten on the previously fitted handle bolt.

The handle can be positioned up and down the shaft to suit the operators comfort. operational position

Mixing the fuel


IMPORTANT. Use good quality air cooled 2-stroke engine oil.

This product is powered by a 2-stroke engine and requires pre-mixing fuel with 2-stroke oil.

1. Use fresh unleaded petrol.

You must use 2-stroke oil specifically made for heavily stressed two-stroke engines.

2. Mix the petrol and oil in an approved container. Never mix fuel directly in the line trimmer fuel tank. Use the fuel mixing bottle included with this product.


Mixing has been made easy by including markings on the container included. For example, if unleaded fuel is filled to the ‘400’ mark in the “GAS”

40:1 column of the container, place oil in the container until it reaches the next mark (in the 40:1 OIL markings of the container). Therefore, 400ml of fuel would mean 10ml of oil must be added.


Never use any type of pre-mixed fuel/oil direct from fuel stations. This may include special blends intended for use in mopeds, motorcycles, etc.

3. Mix the fuel thoroughly and also each time before fuelling.

4. Always pre-mix in small quantities. Never mix quantities larger than what will be used in a 30-day period.

Note. The mixing bottle provided is NOT for the storage of fuel. This container is solely for mixing of fuel only.

Ensure to keep this container in a safe storage location, empty of fuel and out of reach of Children.


Filling The Tank


Always shut off the engine before fuelling. Never add fuel to a machine with a running or hot engine. Move at least 9 m (30 ft.) away from the refuelling site before starting engine. Do not smoke when refuelling or operating the line trimmer.


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

1. Place the line trimmer upright on the ground or on a sturdy bench and wipe any debris from around the fuel cap.

2. Unscrew the fuel tank cap and pour the mixture into the tank with the aid of a funnel.

• Never operate the line trimmer unless it is properly assembled and in good working condition.

• Do not use petrol which contains ethanol or methanol as it may damage the fuel lines and other engine parts.

• Mix only enough fuel for your immediate needs. Do not store pre-mixed fuel.

Starting the line trimmer

Choke control

Start position (choke closed).

Run position (choke open).

1. Move the ignition switch (6) to the ‘on’ position marked with a



3. Be careful not to spill any mixture. If this happens, wipe the spill with a clean rag.

4. Start the engine at least nine metres (30ft) away from the area where the fuel tank has been filled up in order to avoid any risk of fire.

• Always use extreme care when handling fuel! Fuel is highly flammable.

• Never attempt to fuel the line trimmer if the fuel system components are damaged or are leaking.

• Never attempt the refuel the engine while it is running or still warm, allow it to cool before fuelling.

• Never smoke or light any fires near the line trimmer or fuels.

• Always transport and store fuels in an approved container.

• Never place flammable material close to the engine muffler.

• Never operate the line trimmer without a properly functioning muffler and spark plug cover installed.


2. Move the choke lever (14) upwards to the start position

(cold start).

Note. This is not required if the engine is already warm.

3. Push the primer bulb 10 times, until the primer bulb fills with fuel/oil mixture.

4. Squeeze the safety lever (13) and the throttle trigger (8) and engage the throttle lock button (20). Release the throttle trigger. With the throttle lock button engaged, the throttle will be partially open ready for starting.

5. Pull the recoil starter until you hear the engine starting or trying to start. (Under full choke it may only run for 1 or 2 seconds).

6. Push the choke lever half way down and allow the motor to warm up. Restart if the motor stops.

7. Once the engine is fully warm push the choke down fully to the run position (warm start) and pull the throttle trigger and release. This will release the throttle lock.

8. To increase the speed of the cutting line, squeeze the safety lever (13) first, and then squeeze the throttle trigger.

To reduce the speed of the cutting line release the throttle lever.


The cutting spool and line is directly connected to the motor and will always be rotating when the motor is operating.

Stopping the line trimmer

WARNING. The spool and line will rotate whenever the motor is operating.

1. Release the throttle trigger (8) and allow the engine to idle for a few moments.

2. Move the ignition switch (6) to the off position marked STOP.

3. The engine will now stop.

Running in the engine

1. During the first 2–3 hours of work, run the engine at a moderate RPM.

2. We advise you in any case not to maintain your engine at a high speed as the different components must settle with each other during the process of running in the engine.


3. It is at the end of the running in period that the engine will reach its maximum power.

4. After the first two hours of work, stop and make sure that all nuts and screws are securely fastened, and tighten them if necessary.

Use of the petrol line trimmer

This petrol line trimmer is only made to cut grass, small bushes, and shrubs.

• Always use the shoulder strap (17), when using the tool to avoid serious personal injury.

• Perform a few accelerations of the motor without reaching maximum speed and without working to make sure that everything is in good working order.

• Start the engine only when you are close to the working area.

• Place yourself in a well balanced position, stable on both feet.

Operating the line trimmer


Petrol line trimmers transmit vibrations to the operator during use. These vibrations can generate increased fatigue. For this reason, we recommend taking regular breaks during work. We also recommend taking a break after a few hours of work to rest the engine. If abnormal noise or vibration occurs during operation, turn the line trimmer off immediately and have the problem corrected.

1. Keep a firm grip on the trimmer with both hands while in operation. The trimmer should be held at a comfortable position with the rear handle about hip height.

2. Always operate the trimmer at full throttle. Cut tall grass from the top down to prevent grass from wrapping around the spool which may cause the trimmer to overheat.


If grass becomes wrapped around the spool, stop the engine, disconnect the spark plug wire, and remove the grass.


Prolonged cutting not at full throttle may result in oil dripping from the muffler.

Feeding the line


The engine of the petrol line trimmer must be at a complete stop during assembling, repair and cleaning operations that could be necessary.

The line trimmer has a bump feed mechanism which releases the line without having to stop the engine.

1. To release additional line, lightly tap the cutting line and spool assembly (1) on the ground while operating the unit at high speed.


Always keep the line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

2. Each time the head is bumped it releases approximately

2cm of line. Release the line until it strikes the cut off knife (2). This may require several taps.


The cut off knife (2) on the safety guard (3) will automatically cut off any excess line. For best results tap the head on hard soil or bare ground. Never bump the spool head on concrete as it may crack the spool housing.


Do not hit stones (even small ones), piles of earth, and small pieces of wood or anything else that could be hidden or poorly visible in the grass. If you hit a large object by accident, or if you block the cutting tool due to overloading or having the cutter jammed with grass, you must stop the engine.


All protective devices of the machine as well as protective equipment must be maintained in good operation condition during the period of use.


If the line is too short you may not be able to advance the line by tapping it on the ground. If this is the case, stop the engine and manually advance the line.

Advancing the line manually

1. Push the bump knob in while pulling on both lines to manually advance the line.

2. Release the bump knob and again pull on both lines to advance the line further.

3. If the line still does not advance remove the spool and check the lay of the line. It may be twisted or trapped under over saying line.


Tips for cutting


Beware of bystanders at all times

• Cut the grass like you are in a corridor about 1.5m wide.

Move step by step, moving the machine from left to right and vice-versa. Make sure at each step that you are still well balanced on your feet

• Keep the line trimmer tilted towards the area being cut

• Let the tip of the line do the cutting. Never force the spool into uncut grass.

• Running the line into fences, stone and brick walls, curbs, and wood causes extra line wear, even breakage.

Replacement of the cutting line

1. Stop the engine.

2. Put the petrol line trimmer on the floor in a way that the cutting line and spool assembly (1) is facing up.

3. Open the cutting line and spool assembly (1) by holding the spool housing firmly while rotating the bump knob anti-clockwise.

4. Remove the bump knob completely and remove the spool from the spool shaft. Discard any short lengths of remaining cutting line.

5. Take a 4 metre length of Ø2mm line and halve it.

6. Place the half way mark of the line into the notch in the spool.

7. Wrap the line around the inside of the spool in an anti clockwise direction (following the directional arrows on the spool). Ensure the line is wrapped tightly and neatly.

8. When there is approximately 150mm of line left, lock one of the lines into one of the line location notches in the spool head and the other into the opposing notch.

9. With the spring fitted onto the shaft of the spool holder insert the spool back into the holder. As you insert the spool, thread the lines through the eyelets and pull firmly to disengage from the notch in the spool.


When inserting the spool into the housing, the spool may need to be rotated slightly so as to locate into the housing. Before the spool is fully inserted into the housing, ensure the lines are free of the notches.

10. Once the spool is fully inserted and the lines are fully through the eyelets, pull firmly on each line to disengage the lines from the spool notches. Ensure the lines are fully clear of the spool notches and the line is passing through the eyelets directly to the spool.

11. To install the spool, line and housing, refer to ‘Fitting the spool’ section of this manual.


On start up test the operation of the bump feed to ensure the line feeds correctly.


After changing the line spool, run the petrol line trimmer under no load for at least a minute to make sure that the line and the tool are both operating correctly. Use only the line spool as recommended by the manufacturer.


Never use steel threads and/or three teeth blade other than those provided by the manufacturer.

Always use tools in perfect condition, free of damage.


In high-speed rotation, parts could be projected at very high speed and could involve serious injury and damages to persons and property.



Air filter

Accumulated dust in the air filter will reduce engine efficiency. Increase fuel consumption and allow abrasive particles to pass into the engine. Remove the air filter as often as necessary to maintain a clean condition.

• Remove filter cover (12) by pressing in the sides and lifting it off.

• Light surface dust can readily be removed by tapping the filter.

• Heavy deposits should be washed out in suitable detergent.

• Squeeze out the remaining water an allow the filter to completely dry.

• Add a drop of thin oil to the filter and replace it.

Fuel Filter

• Fuel tank (7) is fitted with a filter.

• Filter is situated at the free end of fuel pipe and can be picked out through fuel port with a piece of hooked wire or the like.

• Check the fuel filter periodically. Do not allow dust to enter the fuel tank. Clogged filter will cause difficulty when starting engine or abnormalities in engine performance.

• When the filter is dirty, replace the filter.

• When the inside of the fuel tank is dirty, it can be cleaned by rinsing the tank out with petrol.

Checking the spark plug

Check the spark plug every 10–15 hours of use.

1. Remove the spark plug cover.

2. Use the spark plug wrench to remove the spark plug, by turning it counter-clockwise.

3. Clean and adjust the spark plug gap to 0.6 – 0.7mm.

Replace any damaged or visibly worn plug with a NGK


CJ7Y spark plug, as listed in the specifications table.

4. Install the spark plug finger tight in the cylinder head, then tighten it firmly with the spark plug wrench.


• It is recommended once you first use your petrol line trimmer to get it serviced after 15 hours of use.

• From thereafter, service the petrol line trimmer every 2 years.

Storage and maintenance after use

• When you finish working, clean the petrol line trimmer completely, making sure there is no grass or dirt wrapped in the cutting tools, and put it back into its package in order to avoid its hurting you or other people during transport.

• Be aware to not hit or cut the fuel tank (7) while you put it onto the ground. Do not let the petrol line trimmer fall down to the floor or it may damage the machine.

• Store the petrol line trimmer away from direct sunlight.

• Do not store in a nylon bag as this can encourage the formation of mould.

• At the end of the season, give the petrol line trimmer an overall cleaning and a thorough check.

• Do not leave the petrol line trimmer resting on the floor for extended periods as it could cause the shape of the guard to alter, posing a safety risk. Hang it off the floor by the top handgrip.

Whenever the machine is not used for a long period of time, proceed as follows:

• Empty the fuel tank completely.

• Protect all metal engine parts from corrosion by coating them with oil.

• Remove the spark plug, put a few drops of oil into the cylinder and then pull the recoil starter 2 to 3 times in order to distribute the oil evenly. Replace the spark plug.



Power loss or sudden stopping of the engine

• Check whether the fuel tank is empty.

• The mixture does not reach the carburettor.

Clean the fuel filter in the fuel tank.

• There is water in the mixture. Drain and rinse all the fuel system.

• The air filter is dirty. Clean the air filter.

• There are carbon deposits in the cylinder exhaust pipe or the muffler. Clean those or change the muffler.

Bad quality cut

• Overloaded cutting due to too high grass or too thick for engine power.

• Wrapped vegetal material on the cutting tool.

Line will not advance

• Line welded to itself. Lubricate with silicone spray.

• Not enough line on the spool. Install more line. Refer to

“Replacement of the cutting line” earlier in this manual.

• Line worn too short. Pull lines while alternately pressing down on and releasing bump knob.

• Line tangled on spool. Remove line from the spool and rewind. Refer to “Replacement of the cutting line” earlier in this manual.

• Engine speed too slow. Advance line at full throttle.
