OPERATION
IC75 ENG 3-4
WARMING UP THE MACHINE
IMPORTANT
Do not increase the engine speed quickly when
hydraulic oil is cool (below 20
°
).
The proper hydraulic oil temperature is
approximately 50
°
C to 80
°
C. If you should carry
out works at low temperature, warm up the engine
until the hydraulic oil temperature rises to
approximately 20
°
C before starting works.
1. Idle the engine for approximately 10 minutes to warm it
up after starting it.
2. If the hydraulic oil temperature is low, continue
warming up for approximately 3 to 5 minutes with the
dump lever to the “Lower” position to increase the
hydraulic oil temperature, when it is low.
3. Move the machine forward and backward and raise
and lower the body several times to warm up the
mechanisms.
