6. Make a tension adjustment to the rubber
track according to "Check /Adjust Rubber
Track Tension" on page 5-64.
7. Ensure that adequate engagement and
tension of the rubber track, sprocket, and
idler are obtained.
8. See "OUTRIGGER STOWING" on page 4-45
to stow the outriggers and lower the machine
on the ground.
Checking After Starting Engine
Check the followings in this section after starting
the engine and before starting the first work every
day.
CAUTION ： The checkups described in this
section should be carried out after starting the
machine.
See "STARTING ENGINE" on page 4-15 and
later to execute the engine startup, travelling
operations, outrigger operations and crane
operations.
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.
Especially, with the new machine or when a new
part was installed, "initial slack" appears with 5 to
30 hours of driving after adjusting the tension to
the specified value.
Adjust the tension frequently until the period of
"initial slack" passes. This will prevent "rubber
track from coming off due to insufficient tension on
the rubber track".
