MAINTENANCE

Replacing the drive belt

!

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.

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

!

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.

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
