1. Adjusting the electric clutch
This adjustment should be done every 500 hours of
operation or annually, whichever comes first. In case
the machine is heavily used, air gap settings should be
checked more often.
The electric clutch serves 2 functions in the operation
of the mower:
• Starting and stopping the power flow to the cutter
blades.
• The clutch also acts as a brake to assist in stopping
blade rotation when the PTO is switched off or the
operator presence control is interrupted.
When the clutch is disengaged, the air gap between the
armature and rotor should be within the specification
below.
Air gap 0.4 mm (0.015 in.)
