Checking function of accumulator
For details of handling the accumulator, see Section "Accumula-
tor (2-34)".
Accumulator for E.C.S.S.
When the E.C.S.S. 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 E.C.S.S. 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.
