Safety instructions  
WARNING. Read and understand all instructions.  
Failure to follow all instructions listed below may result  
in electric shock, fire and/or serious injury. The term  
“power tool” in all of the warnings below refers to your  
mains-operated (corded) power tool or battery-operated  
(cordless) power tool.  
If devices are provided for the connection of dust  
extraction and collection facilities ensure that these  
are connected and properly used. Use of these  
devices can reduce dust-related hazards.  
Power tool use and care  
Do not force the power tool. Use the correct power  
tool for your application. The correct power tool will  
do the job better and safer at the rate for which it  
was designed.

Store idle power tools out of the reach of children and  
do not allow persons unfamiliar with the power tool  
or these instructions to operate the power tool. Power  
tools are dangerous in the hands of untrained users.  
Take care not to spill fuel. When refuelling the line  
trimmer ensure that the motor has been switched off.  
Prevent the spilling of fuel as this may also ignite with the  
hot motor. Never refuel whilst the engine running.  
Maintain power tools. Check for misalignment or binding  
of moving parts, breakage of parts and any other condition  
that may affect the power tool’s operation. If damaged,  
have the power tool repaired before use. Many accidents  
are caused by poorly maintained power tools.  
Be careful where you store the line trimmer. Store the  
line trimmer in a dry area away from flammable liquids.  
Keep your distance. The line trimmer emits exhaust  
fumes. Ensure bystanders keep a safe distance.  
Ensure you use oil-mix fuel. Ensure that you mix  
40 parts unleaded fuel to 1 part 2-stroke oil. If not, the  
engine will overheat and cause damage to your line  
trimmer.  
Keep cutting tools sharp and clean.  
Properly maintained cutting tools with sharp cutting  
edges are less likely to bind and are easier to control.  
Use the power tool, accessories and tool bits etc.,  
in accordance with these instructions and in the  
manner intended for the particular type of power  
tool, taking into account the working conditions  
and the work to be performed. Use of the power tool  
for operations different from intended could result in a  
hazardous situation.

Note. The cutting spool and line is directly connected to  
the motor and will always be rotating when the motor is  
operating.  
Operating the line trimmer  
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.  
IMPORTANT. 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.  
2. Move the ignition switch (6) to  
the off position marked STOP.  
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.  
3. The engine will now stop.  
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.  
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.  
Note. If grass becomes wrapped around the spool, stop  
the engine, disconnect the spark plug wire, and remove  
the grass.  
Note. Prolonged cutting not at full throttle may result in oil  
dripping from the muffler.

Feeding the line  
Tips for cutting  
WARNING. 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.  
Note. 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.  
Note. 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.  
IMPORTANT. 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.  
WARNING. 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.  
Note. All protective devices of the machine as well as  
protective equipment must be maintained in good operation  
condition during the period of use.  
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  
Note. 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.  
wrapped tightly and neatly.  
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.

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.  
Maintenance  
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.  
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.  
Heavy deposits should  
be washed out in suitable  
detergent.  
Note. 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.  
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  
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.  
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.  
11. To install the spool, line and housing, refer to ‘Fitting the  
spool’ section of this manual.  
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.  
Note. On start up test the operation of the bump feed to  
ensure the line feeds correctly.  
When the filter is dirty, replace the filter.  
CAUTION. 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.  
When the inside of the fuel tank is dirty, it can be cleaned  
by rinsing the tank out with petrol.  
WARNING. 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.  
WARNING. In high-speed rotation, parts could be projected  
at very high speed and could involve serious injury and  
damages to persons and property.
