OPERATION
IN COLD AREAS
(Ambient temperature below 10°C (50°F))
NOTICE
Do not perform operations or suddenly operate the levers when the
hydraulic oil is at a low temperature. Always perform the warming-up
operation until the hydraulic oil temperature monitor displays the green
range. This will help extend the machine life.
Do not suddenly accelerate the engine before the machine reaches full
operating temperature.
Do not run the engine at low or high idle for more than 20 minutes. This
will cause oil leaks from the turbocharger oil supply piping.
If it is necessary to run the engine at idling, apply a load from time to
time or run the engine at a mid-range speed.
If engine oil pressure caution lamp (3) flashes or the buzzer sounds
intermittently, stop the engine and check for the cause.
1.
Turn fuel control dial (1) to the center position between LOW
IDLE (MIN) and HIGH IDLE (MAX) and run the engine at
medium speed for about 5 minutes with no load.
2. Blade control lever (2) to the full RAISE position, then hold the
lever in position, and operate slowly to the left tilt relief and right
tilt relief positions for 5 minutes.
3. Finally, operate blade control lever (4) and ripper control lever
to operate the blade and ripper cylinders several times.
If the oil temperature in the work equipment is not properly
raised, there will be a time lag in the response of the work
equipment and steering.
4.
After warm-up is completed, check gauges and caution lamps
for proper operation. If any problem is found, repair it.
Continue to run the engine under a light load until engine
coolant temperature gauge indicator (4) is within the green
range (B).
(A): White range
(B): Green range
(C): Red range
REMARK
If the power train oil temperature is not raised sufficiently, it will take
longer to accelerate to the maximum speed.
5. Check for abnormal exhaust gas color, noise, or vibration. If any problem is found, contact your Komatsu
distributor.
