Warming Up Operation In Cold Weather - Hitachi ZW 310-6 Operator's Manual

Warming Up Operation in Cold Weather

IMPORTANT: Right after the engine starts, the engine
speed will be kept to slow idle speed for maximum 35
seconds even if accelerator pedal (3) is operated.
d
WARNING: After starting the engine, start the
machine operation only after confirming that the
engine speed changes by operating accelerator pedal
(3).
Otherwise, the machine or the front attachment may
unexpectedly start moving, possibly causing accidents
such as crash.
d
CAUTION: If the hydraulic oil temperature is low,
perform cold weather warm up. Operate the machine
only after the loader front operating speed becomes
normal. Operating the machine without warming up
operation causes damage to the engine and hydraulic
components. Be sure to perform warm up, not only
to protect the hydraulic components from being
damaged, but also to ensure safe operation.
f
NOTE: Illuminations such as headlight, work light or room
light may become dim during the engine preheat operation at
cold temperature.
1. Run the engine at slow idle speed for more than 5
minutes.
If the [Warming Up Operation] in the multi-monitor
setting menu is set to "ON" (enabled), the engine speed
automatically increases from slow idle to 1000 min
(rpm) and enters warm-up mode when hydraulic oil
temperature is 0 °C or lower.
Further, when either hydraulic oil temperature becomes
30 °C or higher, or engine coolant temperature becomes
40 °C or higher, the warm-up mode is automatically
canceled, and the engine runs in slow idle mode.
(Do not operate the machine until the needle of coolant
temperature gauge (1) starts swinging.)
