Carry out the warm-up operation for the hydraulic
equipment until the hydraulic oil temperature monitor
displays the proper temperature. (When the hydraulic
oil temperature is low, the low temperature display
shown in the figure on the right is given.

The warm-up operation for the hydraulic equipment is
necessary not only for the circuit between the pump
and cylinders and between the pump and motor, but
also for the control circuits. Do not carry out the opera-
tion just for one cylinder or motor, or the operation just
in one direction. Carry out the operation in all direc-
tions for all the work equipment (boom, arm and
bucket), swing, travel, and attachment (if equipped).
