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. Lower the boom and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
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 sprocket (Figure 45).

Checking and Adjusting the Track
Tension
Service Interval: After the first 50 hours
Every 100 hours
To check the tension of each track, place 45 lb (20.4 kg)
on the track midway between the front road wheel and
3. Track
the drive sprocket. The track should flex no more than
1/4 to 3/8 inch (0.6 to 1 cm). If it does, adjust the track
tension using the following procedure:
1. Stop the machine in on a level surface and set the
parking brake.
2. Stop the engine, lower the boom, remove the key,
and wait for all moving parts to stop before leaving
the operating position.
3. Loosen the jam nut on the track tensioning bolt and
the clamp bolts on the tension arm (Figure 47).

2. Jam nut
4. Torque the tensioning bolt to 24 to 30 ft-lb (32.5 to
40 N-m) to tighten the track (Figure 47).
5. Ensure that the track deflects less than 1/4 to 3/8
inch (0.6 to 1 cm) when 45 lb (20.6 kg) 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 75 ft-lb (102
N-m).
