Checking function of accumulator
For details of handling the accumulator, see Section "Accumula-
tor (2-37)".
Accumulator for travel damper
When the travel damper switch is ON, the hydraulic spring effect
of the accumulator absorbs the up-and-down motion of the
machine during travel and reduces the swaying.
Drive the machine and compare the up-and-down movement of
the machine during travel when the travel damper switch is ON
and when it is OFF.
If there is no change in the up-and-down movement of the
machine, the gas pressure in the accumulator has probably
dropped.
Please contact your KOMATSU distributor to have the accumu-
lator inspected.
REMARK
Carry out the inspection with the speed range set to 2 - 4, with
the machine traveling at a speed of at least 5 km/h. If the speed
range is 1st or the machine is traveling at a speed of less than
5 km/h, the E.C.S.S. will not be actuated even if the E.C.S.S.
switch is turned ON.
Accumulator for brake damper
When the brake pedal is depressed, the hydraulic spring effect
of the accumulator actuates the brake smoothly.
If any change is felt in the smoothness of the brake operation
during daily operations, the gas pressure in the accumulator has
probably dropped.
Please contact your KOMATSU distributor to have the accumu-
lator inspected.
REMARK
Even if there is any change in the smoothness, there is no drop
in the braking force or brake performance.
