14.6 Steering

If you have difficulty steering the unit, you will need to adjust the steering levers with the special
adjusters.
If the above adjustment does not create enough cable tension, follow the steps below:

14.7 Tracks

14.7.1 Tightening

With use, tracks tend to loosen. When operating with loose
tracks, they tend to slip over the driving wheel causing it to
jump its housing or to work in precarious situation, thus
damaging wear to the housing.
To check track tightness, proceed as follows:
a. Set the machine on a flat surface with compact ground,
better on an asphalt or stone pavement.
b. Lift the machine and set it on blocks or supports rated for
the weight of the machine so that the tracks are
approximately 100mm off the ground.
c. Measure the track midline vs. the horizontal line. The
reading must not be more than 10 - 15mm.
If the distance is greater, proceed as follows:
a. Use the tipping handle to tip the dump box and set it on
blocks or supports rated for the weight of the box.
b. Loosen the locknut A. Tighten bolt B until the correct
tightness is restored.
c. Secure bolt B by tightening locknut A thoroughly.
d. Return the dump box to its original position
WARNING
The adjustment of the chains affect the brakes. Please with great caution proceed as a chain spanned
loss of braking action results.
If the adjustment does not allow further adjustment more, the chain should be replaced.
e. Tilting bring back to the starting position.

1. Loosen the jam nut (3) by turning it counter clockwise with 10
mm wrench.
2. Unscrew the adjust nut (4) to eliminate the play in the cable,
which can occur after initial use or normal wear. Be very careful
not to unscrew the adjust nut too much because this can create
another problem: the loss of traction.
3. Then retighten the lock nut (3).
