Cleaning the Tracks
1.
Park the machine on a level surface and engage
the parking brake.
2.
With the bucket installed and pointing down,
lower it into the ground so that the front of the
traction unit lifts off the ground a few centimeters
(inches).
3.
Shut off the engine and remove the key.
4.
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
traction unit. Do not use high pressure water
between the drive sprocket and the traction unit or
you may damage the motor seals. High-pressure
washing can damage the electrical system and
hydraulic valves or deplete grease.
Important:
Ensure that you fully clean the road
wheels, the front wheel, and the drive sprocket
(Figure
55). The road wheels should rotate freely
when clean.
