Turn fuel control dial (2) to Low idle (MIN) position.
The engine automatic warm-up is cancelled, and the en-
gine speed is lowered.
REMARK
Turbo protect function takes priority over the engine automatic warm-up.
When the turbo protect function activates, run the engine at low idle even the engine coolant temperature is
30 °C or less. Then the engine automatic warm-up starts automatically to increase the engine speed.
For details of the turbocharger protect function, see “TURBOCHARGER PROTECTION FUNCTION (3-174)”.

WARNING
• Before performing the warm-up operation for the hy-
draulic equipment, set the swing lock switch on, check
on the monitor that the swing lock is actuated, then
start the warm-up operation.
• When warming up the hydraulic equipment, check that
there is no person or obstacle in the surrounding area,
then sound the horn and start the operation.
• Perform the warm-up operation for the hydraulic
equipment until the hydraulic oil temperature caution
lamp displays the proper temperature. (When the hy-
draulic oil temperature is low, the low temperature dis-
play shown in the figure is given.)
• Display (A) when temperature is proper: Caution
lamp background (C) is blue.
• Display (B) when temperature is low: Caution lamp
background (C) is white.)
• 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 perform the opera-
tion just for one cylinder or motor, or the operation
just in one direction. Perform the operation in all direc-
tions for all the work equipment (boom, arm and buck-
et), swing, travel, and attachment (if equipped).
• Before operating the travel lever, check the direction
of the track frame.
