OPERATIONS AND CHECKS AFTER STARTING ENGINE 3
WARNING
q
If there has been any abnormal actuation or trouble, turn the starting switch key to the OFF position.
q
If the work equipment is operated without sufficiently warming up the machine, the response of the
work equipment to the movement of the control levers will be slow and may not move as the operator
desires. Always warm the machine to full operating temperature, particulary in cold areas.
WARMING UP OPERATIONS 3
NOTICE
q
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.
q
Do not run the engine at low or high idle for more than
20 minutes. This will cause oil leaks from the turbo-
charger 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.
q
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
idling (MIN) and high idling (MAX) positions and run the
engine at a mid-range speed for 5 minutes under no load.
2. After warm-up is completed, check gauges and caution
lamps for proper operation. If any abnormality is found,
repair it.
Continue to run the engine under a light load until engine
coolant temperature gauge indicator (2) is within the green
range (B).
(A): White range
(B): Green range
