TRACK TENSION ADJUSTMENT - Continued
Adjust the hard throttle so engine idles at 750-850 rpm to maintain hydraulic pressure. Allow engine to idle for
five minutes so that the vehicle will settle into a constant position.
Every time the tracks are loosened by track loosening switch, adjust tension in both tracks
one at a time using the steps listed below.
Move track loosening switch (Figure 2, Item 1) momentarily (two to three seconds) to loosen both tracks.
Vehicle will move slightly as track adjust cylinders retract.

Record measurement from middle of top of No. 4 roadwheel to track.
Dismount vehicle and inspect track. The track should just touch the top of No. 3 roadwheel, and should be
