MAINTENANCE
Replacing the drive belt
•
First release the two bolts and then the adjuster screw to
release the belt tension.
•
Now unscrew the bolts and dismantle the belt guard.
•
Remove the belt from the belt pulley.
•
The cutting head is now loose and can be removed from
the machine. Remove the rear belt guard by releasing the
two screws holding the guard.
•
Replace the drive belt.
•
Assemble in the reverse order as set out for dismantling.
Carburetor
The carburettor is equipped with fixed needles to ensure the
machine always receives the correct mixture of fuel and air.
When the engine lacks power or accelerates poorly, do the
following:
•
Check the air filter and replace if necessary. When this
does not help, contact an authorised service workshop.
Adjusting the idle speed
•
Start the engine and check the idling setting. When the
carburettor is set correctly the cutting blade should be still
while engine is idling.
•
Adjust the idle speed using the T screw. When an
adjustment is necessary, first turn the screw clockwise
until the blade starts to rotate. Now turn the screw anti-
clockwise until the blade stops rotating.
Rec. idle speed: 2700 rpm
Starter
Checking the starter cord
•
Loosen the screws that hold the starter against the
crankcase and remove the starter.
•
Pull the cord out about 30 cm and lift it into the cut-out in
the periphery of the starter pulley. When the cord is intact:
Release the spring tension by letting the pulley rotate
slowly backwards.
!
WARNING! Never start the engine when the
belt pulley and clutch are removed for
maintenance. Do not start the machine
without the cutting arm or cutting head
fitted. Otherwise the clutch could come
loose and cause personal injuries.
!
CAUTION! If the idle speed cannot be
adjusted so that the cutting attachment
stops, contact your dealer/service
workshop. Do not use the machine until it
has been correctly adjusted or repaired.
!
WARNING! When the recoil spring is wound
up in the starter housing it is under tension
and can, if handled carelessly, pop out and
cause personal injury.
Always be careful when changing the recoil
spring or the starter cord. Always wear
protective goggles.
