Servicing the Tracks

Cleaning the Tracks
Service Interval: Before each use or daily
Check the tracks for excessive wear and clean them
periodically. If the tracks are worn, replace them.
1. Park the machine on a level surface, engage
the parking brake (if applicable), and lower the
grinder.
2. Shut off the engine and remove the key.
3. Using a water hose or pressure washer, remove
dirt from each track system.
Important:
Ensure that you use high-pressure
water to wash only the track area. Do not use
a high-pressure washer to clean the rest of the
machine. High-pressure washing can damage the
electrical system and hydraulic valves or deplete
grease.
Important:
Ensure that you fully clean the road
wheels and the drive wheel
wheels should rotate freely when clean.
