The centrifugal clutch has the task of transferring the power from the engine to the cutting equipment's
drive axle. As the name implies, it works according to a centrifugal principle.
This means the clutch's friction shoes are thrown outwards towards the clutch drum at a certain engine
speed. When the friction against the drum is sufficiently great it drives the drive shaft at the same
speed as the engine.
Some slipping occurs between the clutch and the clutch drum when accelerating as well as in the
reversed situation when the cutting equipment jams. Thereby preventing abnormal load changes on the
crankshaft.
The engagement speed has been carefully tested so that the engine can idle without the cutting
equipment's drive shaft rotating.

damage.
Dismantling
The centrifugal clutch is bolted to the
flywheel.
Follow the detailed instructions in the
chapter "Electrical system" when the
clutch is to be dismantled.
Twist apart the clutch.
Inspect the different parts with regard
to wear or damage.
Pay special attention to the ends of the
springs, which in addition to wear, can
also show signs of cracking.
Assembly
Connect the clutch shoes together with
the spring.
NOTE!
Both clutch shoes should be
replaced even if only one of them
is showing signs of heavy wear.
This is to avoid engine vibration
caused by imbalance in the clutch.
Bolt the clutch on the flywheel. Do not
forget the washers (A).
Note the slots on the washer lie closest
to the flywheel. Align with the
equivalent pins on the flywheel.
