section should be carried out after starting

Check / Adjust Rubber Track Tension
CAUTION:
• Set the outriggers and raise the rubber track
for about 50 mm from the ground when
checking/adjusting the tension of the rubber
tracks.
• The standard tension of the rubber track is
that the clearance between the wheel tread
of the track roller at centre and the shoulder
of the rubber track is 5 to 10 mm.
• If the tension is not sufficient even after
injecting the grease, the rubber track or the
sealing of the tension adjustment cylinder
needs to be changed.
Contact us or our sales service agency for
the judgement of whether to replace, repair,
or keep the rubber track.
The rubber tracks are worn out differently
depending on the working conditions and soil
quality. Regularly check the wear and tension of
the rubber tracks.
