CAUTION:
Do not use any automated clutch engagement device which continues to apply pressure to the hand lever after
clutch is engaged. To prevent excessive wear to clutch sliding sleeve and other clutch parts, the hand lever should
be allowed to rest in a vertical position with no external force applied to it once clutch is engaged.
4.0 OPERATION
4.1
Where high inertia loads must be started, engaging the clutch at idle speed may stall the
engine. High inertia loads may be brought up to speed by engaging the clutch for short
periods, (1 second) at intervals long enough to prevent excessive heat buildup in the
friction discs. With extremely high loads, the engine may have to be operated at higher
speeds while engaging the clutch. However, with a combination of clutch control and
careful use of engine speed, a much smoother transition can be achieved by allowing the
clutch to slip. Variations in engine revs are not immediately translated into changes in
drive shaft rotation speed, but rather the friction on the clutch plate allows the drive shaft
to gradually equalize with the speed of the engine.
4.2
Do not engage clutch above 1100 RPM.
4.3
Once the load is turning with the clutch fully engaged, the engine RPM may be
increased.
CAUTION:
UNDER NO CIRCUMSTANCES should the clutch be slipped for more than four seconds maximum
without either fully engaging the clutch or completely disengaging the clutch to allow it to cool. Any
excessive vibration in the PTO should be cause for investigation. All rotating parts of the WPT PTO
are balanced at the factory.
