suddenly drop or be accidentally lowered.
To avoid personal injury or death:
A When lifting the machine itself with an
attachment, place a safety block or safety post

caught in the track. Remove such obstacles before
adjusting the track tension.
A 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 midway between the idler and
the sprocket.
If the seam is positioned incorrectly, the tracks will be
tensioned too loosely, and a further readjustment will
be necessary.
A Rotate the track after adjustment one to two times to
check the tension.
A Additionally following points are to be observed when
adjusting rubber tracks.
(1) If the track loosen more than 50 mm (2.0 in.),
readjust them.
(2) Check track tension 50 hours after initial use and
readjust
thereafter every 50 service hours.
A If there is a SP mark, the adjustment is possible at all
positions.
BSpecial Information when Using Rubber
Tracks
1. When turning, make a slow swing turn. Avoid spin
turns to reduce lug wear and entry of dirt.
2. The relief valve may be activated if too much dirt and
sand clog the tracks. In this case move the machine for
a short distance straight backwards to let the earth and
sand fall off, then a turn can be made.
