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, and lower the boom.
2.
Shut off the engine and remove the key.
3.
Using a water hose or pressure washer, remove
dirt from each track system.
Important:
Use care when using a high-pressure
washer, because it can damage decals, the engine,
and electrical and hydraulic systems, and it can
deplete grease. Ensure that the fuel-tank cap and
oil cap/dipstick are secure to avoid getting water
in the engine. Keep water away from electrical
items and hydraulic valves.
Important:
Ensure that you fully clean the road
wheels and the drive wheel (
). The road
wheels should rotate freely when clean.
