CLUTCH ENGAGEMENT

• The clutch is to be engaged and

disengaged at low engine speeds only.

NEVER ENGAGE OR DISENGAGE

THE PTO/CLUTCH AT ENGINE

SPEEDS IN EXCESS OF 1200 RPM.

Engagement or disengagement of the

clutch at elevated engine speeds can

cause severe clutch damage. This is not

warrantable. Please refer to the clutch

manufacturers’ manual for clutch

adjustment procedures.

• To engage the clutch:

− Engine must be below 1200 RPM

− Infeed chute must be clear of

material

− Feed control bar must be in the stop

(middle) position

− Bring the cutter disk up to speed by

controlling the engagement handle to

slowly engage the clutch. If handle

is bumped or released to quickly, the

clutch will engage to fast and clutch

damage could occur. The Stein

clutch is a spring force clutch and

does not take as much force as an

over-center clutch.

− The clutch is engage fully when the

handle is in a vertical position.

− New clutches or new facings require

several frequent adjustments until the

friction facings have “worn in”. (See

the clutch section for information on

making adjustments.)
