Servicing the Tracks
Service Interval: Before each use or daily—Check the track
tension.
WARNING
Grease in the hydraulic track is highly pressurized;
ensure that the track-tension grease valve is not
loosened more than 1 revolution at a time.
If you remove the track-tension grease valve (found
in the hydraulic-track tensioner) or loosen it too
much, grease can be released and may cause
serious injury or death.
Tightening the Track Tension
If the track seems loose, tighten the track tension as follows:
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Remove dirt and debris found around the track-tension
grease valve (
Figure 139 ).
Important:
Ensure that the area surrounding
the track-tension grease valve is clean before
beginning to adjust the track tension.
3. Remove the retaining bolts and cover that house the
track-tension grease valve.
4. Apply grease to the fitting until the tension reaches
31,026 kPa (4,500 psi) as shown in
Figure 139 .
