Initial Maintenance
Warning!
These maintenance practices must be followed every hour for the first eight hours of
operation; the practices must also be performed every hour for the first eight hours following the
removal/replacement of any of the components named in this section. Check daily thereafter.
1. Tighten the clutch bolts holding the slip clutch to the input shaft of the gearbox.
Caution! Failure to tighten the keeper bolts will shorten the life of the slip clutch hub.
2. Check for debris deposited between the blade bar and the blades. Debris found jamming or
locking the blades must be removed to insure that the blade may pivot freely on the blade bolt.
Danger!
Failure to maintain freely pivoting blades will cause severe vibration or blade breakage
which will result in injury or death. Blades that are bent or deformed may not pivot and must be
replaced.
3. Tighten blade bolts and blade bar nut. See Tightening Blade Bolt section on Page 23.
Warning! Failure to tighten blade bolts and blade bar nut can cause blade bolts, blades, or output
shafts to break, which can result in injury or death.
4. Check for debris deposited around the output shaft or tailwheel axle.
5. Tighten gearbox mounting bolts.
Caution!
Failure to keep the gearbox bolts tightened can cause the blades to strike the bottom of
the cutter deck or break the output shaft of the gearbox.
