[TENSION ADJUSTMENT]
If the “tension check” of the rubber track found the tension lower than standard tension of the rubber track,
make adjustments as described below.
Working with the loose rubber track (the tension of the rubber track at 15 mm or more) will cause run-off or
early wear of the core metal.
• LOOSE TENSION (INCREASE TENSION)
• Have a grease gun (pump) ready.
1. Inject the grease from the grease valve (1) using the grease gun.
2. Perform the following tasks to verify the proper tension.
(1) See “Operation 2.24 Outrigger Stowing Operation” to stow
the outriggers and lower the machine on the ground.
(2) Move the machine forward/backward.
(3) See “Operation 2.14 Outrigger Setting Operation” to set the
outriggers and raise the crawlers again for about 50mm from
the ground.
3. Perform the “tension check” of the rubber track again.
If the tension is not appropriate, make another adjustment.
4. See “Operation 2.24 Outrigger Stowing Operation” to stow the
outriggers and lower the machine on the ground.
