Servicing the Tracks
Service Interval: After the first 50 hours—Check and
adjust the track tension.
Before each use or daily—Clean the
tracks.
Before each use or daily—Check the
tracks for excessive wear (If the tracks
are worn, replace them.)
Every 100 hours—Check and adjust
the track tension.
Every 250 hours/Yearly (whichever
comes first)—Check and grease the
road wheels.
Cleaning the Tracks
1. With a bucket on the loader arms, lower the bucket
to the ground so that the front of the traction unit
lifts off of the ground a few inches.
2. Stop 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
traction unit. High-pressure washing can damage
the electrical system and hydraulic valves or deplete
grease.
Important:
Ensure that you fully clean the road
wheels, the tension wheel, and the drive sprocket
(Figure 45). The road wheels should rotate freely
when clean.

There should be 2-3/4 inches (7 cm) between the tension
nut and the back of the tension tube (Figure 46). If not,
adjust the track tension using the following procedure:
