OPERATING THE ENGINE
Cold Weather Warm Up
IMPORTANT: At starting the engine, the engine RPM
(min
-1
) is kept at low idle for maximum 35 seconds to
warm up the coolant or hydraulic oil.
After this period, the engine RPM will increase by
applying the accelerator pedal (3).
IMPORTANT: Do not idle the engine for excessively long
periods of time.
Long periods of idling (more than 10 minutes) can
damage an engine because combustion chamber
temperatures drop so low the fuel can not burn
completely.
This will cause carbon to form in the injector spray
holes and on the piston rings and can result in stuck
valves.
d
WARNING: Do not operate the machine while the
engine RPM is being kept at low idle, otherwise, the
machine or the front attachment could unexpectedly
move that may result in serious injury.
d
CAUTION: In case the hydraulic oil temperature is low,
perform cold weather warm up. Operate the machine
only after loading linkage speed is normal. Operating
the machine without warming up first 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.
1. Run the engine at slow idle speed for more than 5~10
minutes to warm up.
If the [Warm Up Operation] in the multi-monitor
setting menu is set to "ON" (enabled), the engine speed
automatically increases from slow idle to 1000 min
-1
(rpm) and enters warm-up mode when hydraulic oil
temperature is 0 °C (32 °F) or lower.
Further, when either hydraulic oil temperature reaches
30 °C (86 °F) or higher, or engine coolant temperature
reaches 40 °C (104 °F) 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 moving.)
f
NOTE:
At this time, do not operate the engine in slow or fast speed.
Use medium engine speeds for safe and quick warm up.
Refer to page 1-67 for Warm Up Operation setting menu.
When auto idling-stop setting is ON, the engine may stop
during warm up. To avoid this situation, deactivate the auto
idling-stop or set the auto idling-stop activating time longer.
Refer to page 1-53 for Auto Idling Stop setting menu.
