WARNING
q
Stop the machine on firm and level ground, raise the
front and rear wheels until they are not in contact with
the ground any longer and engage all the safety locks
before stopping the engine.
q
Secure the machine in this position by applying bearing
blocks under the front part of the frame.
FRONT CHAINS
After raising the front part of the machine and securing it in this
position with safety blocks, mark a point on the outer perimeter
of the front rim and, moving the wheel, make sure that the
point moves of a distance included between 2 and 6 mm. This
range determines the correct tension of the chain.
Repeat this operation also for the opposite wheel.
REAR CHAINS
After raising the rear part of the machine and securing it in this
position with safety blocks, mark a point on the outer perimeter
of the rear rim and, moving the wheel, make sure that the point
moves of a distance included between 2 and 6 mm. This range
determines the correct tension of the chain.
Repeat this operation also for the opposite wheel.
IMPORTANT
q
Check the tension on the front and rear wheels and if
the slack exceeds 6 mm, contact your Komatsu Dealer.
