MAINTENANCE
Press on the belt tensioner with your thumb to tension the 
belt. Now tighten the screw holding the belt tensioner.
Fit the belt cover.
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.
Changing a broken or worn starter cord
Remove any remnants of the old starter cord and check 
that the return spring works. Insert the new starter cord 
through the hole in the starter housing and in the cord 
pulley. 
!
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.
