
Tension the tracks as specified:
1. Apply grease (2) to the grease nipple
(1).
(1) Grease nipple
(2) Grease gun
2. Tension the track in the lifted position, so
that the distance "A" (clearance between
the track roller and the inside surface of
the track) is 0.4 to 0.6in. (10 to 15mm)
(see illustration). In this case, the track
seam is positioned on the top center
between the idler and the sprocket.
DANGER
To avoid serious injury or death:

Do not work under the machine
in this condition.

For your safety do not rely
on
hydraulically supported
devices, they may leak down
and suddenly drop or be
accidentally lowered.
(1) Seam (Mark “oo”) (A) 0.4 to 0.6 in. (10 to 15 mm)
IMPORTANT:

Make sure that no obstacles, such as
stones are caught in the track. Remove
such obstacles before adjusting the track
tension.

Track seam
The ends of the rubber track are joined
with a seam. When adjusting the tracks,
the seam must be positioned on the
top center between the idler and the
sprocket.
If the seam is positioned incorrectly, the
tracks will be tensioned to loosely, and a
further readjustment will be necessary.

Rotate the track after adjustment one to
two times to check the tension.

Additionally following points are to be
observed when adjusting rubber tracks.
1) If the track slackens more than 0.98 in.
(25mm), readjust them.
2) Check track tension 30 hours after
initial use and readjust if necessary.
Check and adjust thereafter every 50
service hours.
