POSSIBLE DANGEROUS SEPARATION OF THE TRACK FROM THE TEETH.
Replacing Rubber Tracks

face utilizing the outriggers.
2. Remove the screws and remove cover 3 as shown

3. To loosen the track, slowly unscrew valve 1 in a
counter-clockwise direction. Do NOT exceed one
(1) rotation.
4. Allow grease to drain. If grease does not drain,
slowly rotate the track.
5. Insert three steel pipes 4 between the rollers of the
track. Turn the driving wheel backwards 5 to
engage the track tensioning wheel. Apply an out-
ward force 6 to lift the track from the track tension-
ing wheel.
