MacDon PW8 Pick-Up Header - Manual (Page 79)

OPERATION
3.12.7 Driveline
Clutch
The header to combine driveline contains a radial pin
clutch (A) to provide protection against overload. When an
obstruction encounters the auger and creates an overload,
the clutch will slip and emit a rattling sound and pulsating
motion when slippage occurs.
Frequent slippage for more than two or three seconds may
result in clutch damage.
IMPORTANT:
Prolonged operation of the header with the clutch
slipping will cause damage to the header and/or
clutch.
If the clutch becomes permanently damaged, refer to
Replacing Driveline Clutch, page 100 .

Guard
DANGER
To avoid serious injury or death, do not operate machine if guard is missing or not in place.
The driveline guard (A) normally remains attached to
the driveline. Tethers (light chains) (B) on either end of
the driveline guard prevent rotation of the guard. The
guard can be removed from the driveline for maintenance
purposes. See Section
Removing Driveline Guard, page
