MAINTENANCE
26 – English
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.
Carburettor
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
!
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! Contact your dealer/service
workshop, if the idle setting cannot be
adjusted so that the blades are
stationary. Do not use the machine until
it has been properly adjusted or repaired.
