4.8.1.i
CHECKING AND ADJUSTING THE FRONT
WHEEL TOE-IN
This check must be carried out according to time intervals fixed by
the operator, since any anomaly regarding the wheel toe-in is due
to impacts or vibrations that depend on the type of surface on
which the machine works.
Another reason that should lead the operator to perform this
check is the excessive wear of the front tyres.
The machine has been designed with a toe-in equal to 0 mm.
Every adjustment must restore this value and must be carried out
on the coupling bars (1) after loosening the nuts (2) that lock
them.
(Use 27 and 19 mm wrenches).
During this check and the relevant adjustment, it is advisable to
check also the conditions of the articulated heads (3); if a consid-
erable slack is observed, change them immediately.
4.8.1.j
CHECKING THE BRAKING EFFICIENCY
IMPORTANT
q
During running-in, check the braking efficiency after the
first 100 hours of operation.
q
Perform this check on firm, level ground, with no people or
obstacles around.
This check must be carried out after setting the work equipment in
the travel or transport position and engaging all the safety locks.
1 - Connect the brake pedals (2) with the pin (1).
2 - Release the parking brake and start the engine (see "3.6.2
3 - Engage the 2
nd
speed and the forward gear.
4 - Accelerate until reaching the maximum speed.
5 - Press the brake pedals. The machine must brake smoothly,
on a straight line, and the tension of the pedals must be con-
stant.
Otherwise, contact your Komatsu Dealer.
