Centrifugal clutch
The centrifugal clutch has the purpose of
transferring the power between the engine and
the cutting equipment. As the name implies it
works according to the centrifugal principle.
This principle implies that the clutch's friction
shoes are slung outwards towards the clutch
drum at a specific engine speed. When the friction
against the drum becomes suf ficient it is driven
round at the same speed as the engine.
There is a certain degree of slip between the
clutch and the clutch drum during acceleration,
but also in the reverse case if the cutting equipment
should stick. This avoids irregular load alternations
on the crankshaft.
The engagement speed is carefully tested to that the
engine can run at idling speed without the cutting
equipment rotating.
!
WARNING!
Never start or test run the engine if the clutch
cover is removed. The clutch can come loose
and cause personal injury.
