5. Turn ignition switch to START.
The engine has an ether start system that automatically
injects a preset volume of ether into engine, when the
ambient temperature is below a preset degree.
CAUTION
Starter Motor Damage!
If engine does not start after cranking 30 seconds, wait 2
minutes so starter motors can cool before trying again.
6. Increase engine speed as necessary to keep engine
running after engine starts. Allow engine to run until it
begins to warm up.
WARNING
Engine Damage!
Engine must have adequate oil pressure within 15
se co nds a fte r s tart ing . If no t, sh ut do wn en gine
immediately to avoid damage.
7. If disengaged, set engine speed at 1,300 RPM and
engage engine clutch slowly to give engine time to
take on added hydraulic load.
8. It is normal for engine speed to drop to as low as 400
RPM as clutch is engaged (due to increased load of
pumps and pump drive):
• If engine stalls, disconnect clutch and allow a longer
warm-up period.
• If engine remains running, engine speed should
increase above 600 RPM within 5 seconds. If it
doesn't, stop engine or disengage clutch
immediately to avoid pump drive damage.

It is also normal for system fault alert and engine
warning/diagnostic lights to come on after engine starts.
Alert and lights should go off as engine oil pressure,

hydraulic oil pressure, and hydraulic oil temperature rise
Disengaged
to normal – if no other faults exist.
Once clutch is engaged (and engine remains running),
decrease engine speed as low as possible (above 600
RPM) without stalling engine to give system fault alert
and engine warning/diagnostic lights time to turn
off.

9. Run engine at low idle until hydraulic oil temperature is
Engaged
at least 60°F (16°C) and all faults are off.
FIGURE 3-17
Do not run engine below 600 RPM for longer than 5
seconds with clutch engaged. Serious damage to pump
drive will result.
Do not operate crane when system fault alert or engine
warning/diagnostic lights are on. If faults don't turn off
after startup or come on during operation, proceed as
follows:
•
•
•
•
•
Continuous operation with hydraulic oil temperature
above 180°F (82°C) can damage hydraulic components.
Troubleshoot hydraulic system if oil temperature exceeds
180°F (82°C).
10. Confirm current selected crane mode or select and
confirm another crane mode. Load drums and boom
hoist are inoperable until this step is performed
(operating limit alert will come on and CONFIRM MODE
will appear on digital display if operation is attempted).
Prevent damage to live mast assist arms and cylinders
during cold weather:
•
•
Cylinders and arms will bend under weight of live mast if
this precaution is not taken.

OPERATING CONTROLS AND PROCEDURES
CAUTION
Machinery Damage!
Determine fault on digital display
Land loads if possible. Otherwise, apply drum brakes
and park all functions
Move all control handles to off
Stop engine
Correct cause of fault
CAUTION
Mast Assist Damage!
Do not attempt to lower live mast with boom hoist until
temperature of hydraulic oil is 60°F (16°C).
Once oil is at above temperature, fully extend and
retract live mast cylinders twice to fill with warm oil.
