HOW TO OPERATE CARRIER
2.
◆
Steps to be taken after engine
has started
★
Do not make engine to accelerate abruptly before it has been warmed
up.
After the engine has started, do not rush into
crawling the crane but take the steps as fol-
lows:
Warm up
the engine
for about 5
minutes
CAUTION
3
Check the engine for unusual vibration
and noise, bad odor, and for color of
exhaust gas.
1
Make sure that each warning lamp does
not light after the engine has started.
If any one of the lamps lights, stop the engine
to find the cause.
2
After idling the engine at a lower speed
for about 5 minutes to warm it up,
shift each operation lever with the accelera-
tor pedal depressed halfway to warm up the
hydraulic system.
The warming-up allows not only the lubricant
to circulate well enough through each operat-
ing section but also allows the engine to be
warmed up gradually to raise temperature of
both water and oil which in turn creates the
better operating conditions.
4
Check the hydraulic equipment and the
engine for oil leakage.
