FUEL
Petrol is very ammable. Do not use or fuel the multicutter near a
ame, sparks or while smoking. Allow the engine to cool before
re-fuelling. Fuel the engine at least 3m away from your work area.
• Use a ratio of 25:1 unleaded petrol to mineral oil. Mix well in an
appropriate mixing bottle. For semi-synthetic or synthetic oils check
the oil manufacturer's guidelines to determine the correct ratio.
• 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 a separate can and only stored for 4-6 weeks. If the
multicutter 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.

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. Nuts are usually already fitted in the lower handle.
Washers should be located under the screw heads.
Attaching the Shoulder Harness:
• Connect the latch on the shoulder harness to the harness loop,
located on the upper shaft.
• Adjust the strap length to a comfortable position, making sure that
any excess strap is secure.
Fitting the Attachments:
• The attachments connect to the power unit by means of a coupler device.
• Loosen the rotating knob on the coupler of the power unit shaft.
• Push in the button on the attachment shaft.
• Align the button with the guide recess on the coupler and slide the two shafts together
to connect the slot and socket inside the shafts.
• Rotate the attachment shaft until the button locks in the positioning hole.
• Tighten the rotating 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.

Hedgetrimmer Attachment:
• Locate the bracket on the plane of the gear head and position the locking screw (3) through
the adjusting hole in the bracket.
• Use the two Screws (25) and at washer (26) to attach the bracket to the gear head.
• Use the locking knob (4) to fasten the bracket onto the assistant gear head (6).
Check the tightness of the bracket locking screws (25) before every use of the
hedgetrimmer.
The hedgetrimmer can be adjusted to six different cutting angles to suit all applications.
Operating the Hedgetrimmer:
• Always have a rm footing and use two hands.
• It is advisable to cut a hedge from the bottom up sweeping the cutter bar in an arc as you
move along the hedge. The double edged cutter blades allows use by left or right handed
operators.
• To cut the top of the hedge, hold the cutter bar at an angle of 0-10 degrees as you swing
the hedge trimmer horizontally. Sweep the cutter bar in an arc towards the outside of the
hedge so that the cuttings are swept onto the ground.
• Pay special attention when cutting hedges which are laid out along a wire fence. If the
blades make contact with the wire damage may occur.
• Do not use the hedge trimmer for long periods of time - take a break of 10-15 mins after
every 50 mins of use or after using one tank of fuel.
• If the blades hit a stone, wire or other foreign object, turn off the engine and check for any
damage to the blades immediately. Replace any damaged blades before continuing.
• Do not attempt to remove any twigs or branches jammed in the cutter blades without rst
turning the engine off.

Brushcutter Attachment:

Page 11
ASSEMBLY, cont’d
Operating the Brushcutter:
• Operate the throttle trigger with your right hand and hold the barrier handle with your left
hand.
• Always keep a rm grip with both hands during operation.
• The brushcutter should be held at a comfortable position with the trigger handle about hip
height. Adjust the harness to suit.
• Maintain a rm footing in case the machine hits a solid object and kicks back.
• Do not use the brushcutter near fencing, posts, buildings or other immoveable objects -
use the line trimmer attachment.
• Best results are obtained if you cut from right to left in a broad sweeping action.
• If a hard object is hit, stop the machine and inspect for any damage straight away.
• Never attempt to sharpen the blade. It is reversible so should be turned over when blunt.
The blade must remain balanced. Always check for any damage before use and replace
a damaged blade immediately.
To avoid burns from the hot engine, never operate the unit with the bottom of the
engine above waist level or on the operator's left side.Always position the unit on the
user's right side.

ASSEMBLY, cont’d
Line Trimmer Attachment:
• Slide the shield onto the attachment shaft and t over
the bracket, as in Fig. 11.
• Fix the bolt through the holes in the tabs on the shield
and the slots in the bracket on the attachment shaft.
• Secure, as shown in Fig. 11, using the at washer,
lock washer and nut.
• Tighten securely and remove the protective packaging
from the line cut-off blade.
Operating the Line Trimmer:
• Operate the throttle trigger with your right hand and hold the barrier handle with your
left hand.
• Always keep a rm grip with both hands during operation.
• The line trimmer should be held at a comfortable position with the trigger handle about
hip height. Adjust the harness to suit.
• Maintain a rm footing in case the machine hits a solid object and kicks back.
• Cut tall grass from the top down to prevent the grass wrapping around the shaft
housing and string head which may cause overheating and damage. If grass becomes
entangled stop the engine completely and remove the grass.
• 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.

Page 13
To replace the line or spool:
• 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-clockwise.
• Remove the 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,
as in Fig. 13, and wind in the direction of the arrow on the spool
(see Fig. 12) keeping the line tight at all times, as in Fig.14.
• Wind the line on until you have about 15cm left then secure the lines
into the slots on the tabs, as shown in Fig. 15.
• Insert the lines on the spool into the eyelets on the trimmer head as
in Fig. 16
• 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 then place the
bump knob/retaining cap onto the drive shaft as in Fig. 17.
• 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.
REPLACEMENT OF SPOOL AND LINE

Page 14
REPLACEMENT OF PRUNER CHAIN
• Remove the sprocket wheel cover (34).
• Remove the guide bar and chain.
• Remove the old chain and replace with the new chain.
• Mount the guide bar and then t the saw chain around the bar and sprocket, paying
particular attention to the correct direction of the chain.
• Fit the chain tensioner into the lower hole of the guide bar (24).
• Attach the sprocket wheel cover and loosely tighten the nut.
• Turn the chain tensioner clockwise until the chain ts snugly onto the guide bar.
• Tighten the sprocket wheel cover nut, then using gloves, pull the chain around the guide
bar to check that the chain has the correct tension without any tight spots.
• Fill the chain oil reservoir with chain oil and before cutting,run the chain at medium
speed to make sure chain oil is thrown off. This ensures that the chain is being
lubricated.
It is very important to maintain proper chain tension as incorrect chain tension can
cause the guide bar to wear and the chain to come off.
Operating the Pruner:
• The Pruner is equipped with a low kickback chain, however, sometimes kickback can
occur so always hold the unit rmly in both hands.
• Thin branches can be cut off with a single cut but if the branch is long it is preferable to
cut it off in several pieces.
• For larger branches follow the diagrams below for a safe clean cut. Make the rst cut
from underneath and cut through one third to half ofthe branch.
• Do not work at an angle higher than 60 degrees as there is a danger of being injured by
branches falling without warning.
Before every use, check the level of the chain oil in the reservoir.

Page 15
Starting the Multicutter:
• Move the ignition switch to the “on” position (Fig. O).
• Move the choke lever upwards to the “start” position (for cold start only) (Fig. P).
• Push the primer bulb 10 times until the petrol/oil mixture lls the primer bulb (Fig. Q).
• Squeeze the safety lever, then the throttle; push in the throttle lock button with your
thumb.
• Pull the recoil starter 2-3 times until the engine res (Fig R).
• Push the choke lever down to the “run” position and pull the starter again until the
engine starts. Squeeze the throttle to release the throttle lock.
Warning: failure to push the choke to the "run" position after the engine has fired
will flood the engine.
• 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 Multicutter:
• Release the throttle trigger and allow the engine to idle for a few moments.
• Move the ignition switch to the “off” position (Fig. T).
Note: The attachments may 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.
Ensure that all nuts, bolts and screws are securely tightened before every use of the
Multicutter.
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.
OPERATION

Page 16
MAINTENANCE
The engine of the multicutter must be at a complete stop during assembling,
cleaning and any maintenance that may be necessary.
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 performance.
• Remove the air lter cover by releasing the securing screws 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 any damaged or visibly worn spark plug.
• Install the new/cleaned spark plug to nger tightness and tighten fully with the spanner.
Servicing:
• We recommend that your petrol multicutter is serviced after 15 hours of use and
thereafter every 2 years.
When you nish working, clean the multicutter completely, removing any dirt and making
sure there is no grass wrapped around the cutting tools. Replace the blade covers on the
hedgetrimmer and pruner.
Be careful not to hit or damage the fuel tank when you put the machine on the ground.
Store away from direct sunlight and preferably hang the multicutter off the oor by the top
handgrip.
If storing for a long period, drain completely of fuel and oil all metal engine parts to protect
them from rusting.
Remove the spark plug, put a few drops of oil into the cylinder and pull the recoil starter a
few times to distribute the oil. Replace the spark plug.
You must periodically check that all screws are securely tightened. Failure to regularly check
the machine may affect performance and operator safety.
