OPERATING PROCEDURES GRT9165 OPERATOR MANUAL
4-8 Published 7-23-2020, Control # 668-02
Diesel Fuel
Diesel fuel with low temperature characteristics is required to
operate the engine when ambient temperatures get near or
below 0°C (32°F). Refer to the applicable engine manual for
proper specifications.
Use correct grade of fuel for prevailing temperature. Diesel
fuel should have a cloud point of 6°C (10°F) less than the
lowest expected temperature. In case of emergency,
kerosene may be added to the fuel to bring the cloud point
down to the required temperature.This will minimize clogging
of filters and small passages by wax crystals. Addition of
kerosene is NOT recommended for general use. Refer to
Arctic Lubricants and Conditions, page 6-5 of this operator
manual.
ENGINE OPERATION
Start-up and shutdown procedures for most diesel engines
are generally the same. Therefore, the following procedures
can be applied, except where specific differences are noted.
(Refer to applicable engine manufacturer’s manual for
detailed procedures).
Jump Starting Hazard
Do not attempt to jump start the crane.
This crane has multiple computer systems (crane control,
RCL, engine & transmission control) that are highly
susceptible to voltage/amperage surges in the electrical
system.
The batteries should be completely disconnected from the
crane electrical system and charged using a battery charger
of appropriate voltage level or replace the batteries with fully
charged batteries. Refer to Charging the Batteries, page 4-8.
Charging the Batteries
When charging the batteries, do not turn on the battery
charger until the charging leads have been connected to the
battery(s). Also, if the battery(s) are frozen, do not attempt to
charge them. Remove the battery(s) from the crane, allow
them to thaw, and then charge the battery(s) to full capacity.
“Slow charging” is preferred to “fast charging”. Fast charging
saves time but risks overheating the battery(s). Slow
charging at six (6) amps or less develops less heat inside the
battery and breaks up the sulfate on the battery plates more
efficiently to bring the battery up to full charge. The use of a
“smart charger” that automatically adjusts the charging
amperage rate is recommended.
Start-Up Procedure
1. Make an under-the-hood inspection for fuel, oil, and
coolant leaks, worn drive belts, and trash build-up.
2. Use the correct grade of oil in the crankcase for the
prevailing temperature to prevent hard cranking.
3. Make sure diesel fuel has a cloud point of 6°C (10°F)
less than the lowest expected temperature. In case of an
emergency, white kerosene can be added to the fuel to
bring the pour point down to the required temperature.
This will prevent clogging of filters and small passages
by wax crystals. The addition of kerosene is NOT
recommended for general use.
4. Make sure battery disconnect switch handle is in the ON
position.
5. Make sure emergency stop switch is not pressed.
6. Make sure parking brake is set to On position and the
transmission shift lever is positioned to Neutral.
NOTE: Engine will not crank unless transmission shift
lever is in neutral.
CAUTION
Engine Damage Hazard!
If Ultra Low Sulfur fuel is not used in engines that require
it, engine performance will quickly deteriorate and the
engine may stop running. The engine warranty will also
be voided.
CAUTION
Do not jump start the crane with a different vehicle,
portable power pack, or other power source. The surge
of power from these sources can damage the crane
electronic controls and computer systems. Jump
starting the crane batteries with a different vehicle
while the engine is running can also damage the donor
vehicle electronics.
DANGER
Diesel engine exhaust can be harmful to your health. Only
operate engine in a well ventilated area or vent exhaust
outside.
CAUTION
Never crank engine for more than 30 seconds during an
attempted start. If engine does not start after 30 seconds,
allow starter motor to cool for two minutes before
attempting another start.
If engine does not start after four attempts, correct
malfunction before attempting another start.
