SERVICE & MAINTENANCE
WARNING
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE,
AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
5.11 DRIVE BELTS
Check the condition of the drive belt annually or after
every 25 hours of operation, whichever comes first. If the
belt is cracked, worn, frayed, or stretched, replace it. To
replace the belt:
1.
Disengage PTO and shut off tractor engine.
2. Remove PTO shaft from tractor and disconnect
machine from three-point hitch.
3. Remove the round shield connected to the belt guard
that covers the PTO shaft by removing the two 5/16"
nuts.
4. Remove the PTO shaft from the chipper/shredder by
loosening the two set screws and pulling the shaft off.
5. Install new belts and make sure pulleys are alligned
to within 1/16". If not, adjust pulleys.
6. Reinstall belt shields and guards. Install PTO shaft
and tighten the two set screws. Install PTO shield.
Never run PTO without all shields in place.
1. Loosen and remove the 3/8" carriage bolt securing
the knife access cover.
5.12 REMOVING THE ROTOR
The rotor weighs in excess of 100 lbs. It is extremely
important to support the rotor to prevent it from falling
or shifting as the shaft is removed.
WARNING
2. Open the access cover, exposing the chipper
shredder compartment.
3. Loosen the bushing bolts holding the drive pulley to
the shaft and remove the pulley.
4. Loosen the set screw in the lock collars. Using a
punch and hammer, tap the lock collars in a direction
opposite of normal rotation so that they can be
removed.
5. Unbolt bearings and lift rotor out of machine.
6. Remove bearings from rotor shaft.
7. Re-install rotor assembly and bearings and tighten
bolts to proper torque.
5.13 PTO DRIVELINE LUBRICATION
1.
Every 8 hours, lubricate PTO cross journals. Make
sure grease purges through all four bearings.
2. Every 8 hours, lubricate PTO inner tubes. Telescoping
members must have lubrication to operate
successfully. Telescoping members without fittings
should be pulled apart and grease should be added
manually with a brush.
3. Every 8 hours, lubricate the PTO shield retaining
bearing. Molded nipples on the guard near each
guard bearing are intended as grease fittings and
should be lubricated every 8 hours of operation.
To prevent personal injury or property damage:
Disconnect the PTO driveline from the source providing
power or disconnect the driveline from the chipper
and make sure that all moving parts have come to a
complete stop, before servicing, adjusting or repairing.
