5. If necessary in cold weather, disengage engine clutch as
shown in Figure 3-18
. This step will disconnect pumps
from engine and aid in cold weather startup.
6. Turn ignition switch to START.
7. Increase engine speed as necessary to keep engine
running after it starts.
Reminder: Engine speed cannot be increased while the
following faults are on. Engine speed can be reduced,
but cannot be increased again until the faults are off.
See Page 3-53
for fault identification.
• Fault 40, High Vacuum
• Fault 61, Dirty Return Filter
8. If engine clutch is disengaged, decrease engine speed
to low idle and engage engine clutch within 20 minutes
after starting engine.
NOTE: Engine clutch may be engaged when temperature
of hydraulic oil is above 0°F (-18°C).
Hydraulic tank heaters are designed to keep the
temperature of hydraulic oil in the tank at a
minimum of 0°F (-18°C).
9. Run engine at low idle until hydraulic oil temperature is
at least 60°F (16°C).
NOTE: It is normal for engine and crane faults to appear
when engine is started. Faults should go away as
soon as engine oil pressure and hydraulic oil
temperature rise to normal (if no other faults exist).
CAUTION
Avoid Engine Clutch Damage!
Observe following precautions for engine clutch:
• Decrease engine speed to idle before engaging or
disengaging clutch
• Do not run engine longer than twenty minutes with
clutch disengaged
• Disengage and engage clutch several times monthly
with engine running
CAUTION
Starter Motor Damage!
If engine does not start after 30 seconds of cranking, wait
a few minutes so starter motor cools before trying again.

CAUTION
Machinery Damage!
Do not operate crane when engine and crane faults exist.
If faults do not go away soon after engine is started or
come on during operation, immediately proceed as
follows:
• Determine fault on Main display, Information screen
• Land loads, if possible, and park all functions
• Move all control handles to off
• Stop engine
• Correct cause of fault
Mast Assist Damage!
Prevent damage to mast assist arms and cylinders during
cold weather:
• Do not attempt to lower live mast with boom hoist until
temperature of hydraulic oil is 60°F (16°C)
• Once oil is at specified temperature, fully extend and
retract mast assist cylinders twice to fill cylinders with
warm oil
• Cylinders and arms will bend under weight of mast if
this precaution is not taken
Machinery Damage!
• Continuous operation with hydraulic oil temperature
above 180°F (82°C) can result in damage to hydraulic
components. Troubleshoot hydraulic system if oil
temperature exceeds 180°F (82°C)
