Read and understand the owner’s manual and labels afxed to
the line trimmer. Learn its application and limitations as well
as the specic potential hazards. Retain these instructions for
reference.
• Use sturdy footwear and a helmet with eye and ear protection.
Protect exposed parts of your body. Wear heavy duty gloves,
preferably made of leather.
• Do not wear loose clothing or jewellery. Keep hair, clothing and
gloves away from moving parts.
• Do not operate the line trimmer if you are tired, ill or under the
inuence of alcohol or drugs.
• Do not smoke when using the line trimmer and ensure caution
when handling fuel. We recommend you fuel the machine at least
3m away from where you wish to work in case any spilt fuel ignites
when starting the engine.
• Ensure that bystanders, children and pets keep well away when
starting or trimming - at least 15m.
• Inspectthelinetrimmer, and in particular the trimming head, before
use for any worn or damaged parts. Do not use until the parts are
repaired or replaced.
• Before starting the engine make sure the trimming head is not
in contact with anything and have a clear work area and secure
footing.
• The line trimmer should not be stored in direct sunlight, or
exposed to high temperatures or damp and wet conditions.
• Clean the trimmer after each use and, if storing for a prolonged
period, drain down the fuel in the tank. Remove the spark plug
and put a few drops of oil into the cylinder before pulling the
starter a couple of times to distribute the oil evenly. Replace the
spark plug.

FUEL
Petrol is very ammable. Do not fuel or use the chainsaw near a
flame, sparks or while smoking. Allow the engine to cool before
re-fuelling. Fuel the engine at least 3m away from your work area.
• Use aratio of 25:1 unleaded petrol to 2-stroke mineral oil, for synthetic
or semi-synthetic use the oil maker's ratio. Mix in the mixing bottle.
• Unscrew the fuel cap, and fuel the machine to 80% capacity. Fas-
ten the fuel cap tightly and wipe up any spillage.
• Ensure that any stored petrol/oil mixture (2-stroke) is clearly
marked in separate can and only stored for 4-6 weeks. If the line
trimmer is not going to be used for a long period, drain the mixture
from the fuel tank, start the engine and drain the carburettor of
any remaining fuel.
• Dispose of any unwanted 2-stroke mixture at an authorised recy-
cling point.

ASSEMBLY AND OPERATION
Assembling the Loop Handle:
• Disassemble the loop handle.
• Position the upper handle over the upper shaft just in front of
the xed rubber grip. The lower handle locates on the under-
side of the shaft and should line up with the four screw holes on
the upper handle. Secure with four screws, washers and nuts.
Attaching the Shoulder Harness:
• Connect the latch on the shoulder harness to the harness eye,
located on the upper shaft.
• Adjust the strap to a comfortable position.
Joining the Bent Shaft to the Upper Shaft:
• The attachment connects to the power unit by means of a
coupler device.
• Loosen the knob on the coupler of the upper shaft.
• Push in the button on the bent shaft.
• Align the button with the guide recess on the coupler and slide
the two shafts together.
• Rotate the lower shaft until the button locks in the positioning
hole.
• Tighten the knob securely.
Note: If the button does not release completely in the positioning
hole, the shafts are not locked in place. Slightly rotate from side to
side until the button locks.
Attaching the Shield to the Curved Shaft:
• Slide the shield onto the attachment shaft and t over the
bracket.
• Fix the bolt through the holes in the tabs on the shield and the
slots in the bracket on the attachment shaft.
• Secure using the at washer, lock washer and nut.
• Tighten securely and remove the protective packaging from the
line cut-off blade.

Starting the Trimmer:
• Move the ignition switch to the “on” position.
• Move the choke lever upwards to the “start” position (for cold start only).
• Push the primer bulb 10 times until the petrol/oil mixture lls the primer bulb.
• Squeeze the safety lever, then the throttle, finally push in the throttle lock button with
your thumb.
• Pull the recoil starter 2-3 times until the engine res.
• Push the choke lever down to the “run” position and pull the starter again until the
engine res. Squeeze the throttle to release the throttle lock.
• Allow the engine to run idle for about 10 seconds to warm it up.
Note: If restarting a warm engine there is no need to move the choke lever or
prime the primer bulb.
Stopping the Trimmer:
• Release the throttle trigger and allow the engine to idle for a few moments.
• Move the ignition switch to the “off” position.
Note: The blade/spool will continue to rotate for a few seconds after the engine has
stopped.
During the rst 10 hours of work run the engine at a moderate speed.
After the rst 2 hours, ensure that all nuts, bolts and screws are
securely tightened.
To Operate:
Always position the unit on the operator’s right side. Using it on the left side will expose
the user to the exhaust and hot surfaces which can result in burns.
Hold the trimmer with your right hand on the rear handle and your left hand on the loop
handle. Keep a rm grip with both hands. The machine should be held at a comfortable
position with the trigger handle about hip height.
Cut tall grass from the top down to prevent the grass wrapping around the shaft housing
and string head which may cause damage from overheating. If grass becomes entangled
stop the engine completely, disconnect the spark plug wire and remove the grass.

REPLACEMENT OF LINE
Follow these steps to replace the cutting line:
• Stop the engine.
• Lay the trimmer on the oor so that the cutting head is facing up.
• Remove the bump knob/retaining cap by turning it anti-clock-
wise.
• Remove empty spool being careful not to lose the spring behind
the head.
• Clean the head thoroughly and inspect for any worn or damaged
parts.
To reload the spool with line:-
• Cut two lengths of spare line 3 metres long.
• Position each line in the two holes located in the centre of the
spool and wind in the direction of the arrow on the spool.
• Wind the line on until you have about 15cm left.
• Secure the lines into the slots on the tabs.
• Insert the lines on the spool into the eyelets on the trimmer head.
• Place the spool on the drive shaft.
• Release the lines from the tabs by sharply pulling each line while
pushing down on the spool.
• Push down on the spool to reveal the drive shaft.
• Place the bump knob/retaining cap on the drive shaft.
• Secure the knob/retaining cap by turning it clockwise.
If you need to replace the whole spool, follow the instructions above,
omitting the references to relling the line.

MAINTENANCE
Before carrying out any maintenance, ensure that the trimmer
engine is at a complete standstill.
Air Filter:
Accumulated dust in the air lter will reduce engine efciency,
increase fuel consumption and allow abrasive particles to pass
into the engine.
Remove and clean the air lter regularly to ensure optimum per-
formance.
• Remove the cover by pressing in the sides and lifting it off.
• Tap the lter to remove light surface dust.
• Heavy deposits should be washed out in soapy water. Allow
the filter to dry completely.
Fuel Filter:
Check the fuel lter periodically but be careful not to allow dust
to enter the fuel tank.
• The fuel tank is tted with a lter which is situated at the free
end of the fuel pipe and can be extracted by using a piece of
hooked wire.
• If the lter is dirty replace it straightaway.
• If the inside of the fuel tank is dirty rinse out with petrol.
Spark Plug:
Check the spark plug after every 10-15 hours of use.
• Remove the spark plug cover.
• Using the plug spanner supplied, remove the spark plug by
turning it anti-clockwise.
• Clean and adjust the gap to 0.6-0.7mm.
• Replace the spark plug if it is damaged or visibly worn.
• Install the new/cleaned spark plug to nger tightness then
tighten fully with the spanner.
Servicing:
• We recommend that your petrol line trimmer is serviced after
15 hours of use and thereafter every 2 years.
