Installation Instructions
Burnish PTO Clutch
After installing the PTO box and the attachment to be
used with the PTO box, the electric clutch must be burnished. The purpose of burnishing the electric clutch is
to burn off coatings on parts that are there to prevent
corrosion before initial use. Burnishing is necessary to
assure correct stopping times.
1. Select a safe area to operate the PTO. With the
parking brake engaged, the PTO switch disengaged,
and an operator in the seat, start the tractor engine.
Run the engine at full throttle.
2. Engage the PTO switch and run the attachment for
fifteen seconds. Disengage the PTO switch and wait
for the PTO to stop.
3. Repeat step 2 ten times.
