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, and lower the hydraulic lift.
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.

Checking and Adjusting the Track
Tension
Service Interval: After the first 50 hours
Every 100 hours
To check the tension of each track, place 20.4 kg (45
lb) on the track midway between the front road wheel
and the drive wheel. The track should flex no more
than 0.6 to 1 cm (1/4 to 3/8 inch). If it does, adjust the
track tension using the following procedure:
1. Park the machine on a level surface, engage the
parking brake, and lower the hydraulic lift.
2. Shut off the engine and remove the key.
3. Loosen the jam nut on the track tensioning bolt
and the clamp bolts on the tension arm
48).

2. Jam nut
4. Torque the tensioning bolt to 32.5 to 40 N∙m (24
to 30 ft-lb) to tighten the track
5. Ensure that the track deflects less than 0.6 to 1
cm (1/4 to 3/8 inch) when 20.6 kg (45 lb) of force
is applied to the track span. Adjust the torque on
the tensioning bolt as needed.
6. Tighten the jam nut.
7. Tighten the clamp bolts and torque to 102 N∙m
(75 ft-lb).
