Grinder Maintenance
Replacing the Teeth
Service Interval: Before each use or daily—Check the
condition of the teeth and rotate or
replace any that are worn or damaged.
Due to the high amount of wear placed on the teeth, you will
need to rotate and replace them periodically.

2. Tooth holder
Each tooth is indexed with 3 positions so you can rotate it
twice, exposing a new sharp edge before replacing the tooth.
To rotate a tooth, loosen the nut securing the tooth (Figure
57). Push the tooth forward and rotate it one third of a turn,
bringing an unused edge to the outside. Torque the nut
securing the toothth to 37 to 45 N-m (27 to 33 ft-lb).
To replace a tooth, remove the nut securing the tooth to
remove it, then install a new tooth and nut in the same
position (Figure 57). Torque the nut securing the tooth to
37 to 45 N-m (27 to 33 ft-lb).

Cleaning
Removing Debris from the
Machine
Important: Operating the engine with blocked screens,
dirty or plugged cooling fins, and/or cooling shrouds
removed, will result in engine damage from overheating.
1. Lower the grinder.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Wipe away debris from the air cleaner.
4. Clean any debris build-up on the engine with a brush
or blower.
Important: It is preferable to blow dirt out, rather
than washing it out. If water is used, keep it away
from electrical items and hydraulic valves. Do
not use a high-pressure washer. High-pressure
washing can damage the electrical system and
hydraulic valves or deplete grease.
5. Clean debris from the oil cooler.
