Depress clutch pedal fully and accelerator about half-way. Engage starter, releasing it as soon as engine
has started. Keep clutch depressed until engine runs smoothly. After engine has started, run it at approximately
1000 RPM. If oil pressure is not indicated within 10-15 seconds, make immediate shutdown, and check lubrication
system. High oil pressure at start-up is not cause for concern. If engine is maintaining oil pressure and the other
systems that should be functioning appear normal, continue to run engine at approximately 1000 RPM until
coolant temperature is at 140° F or above. Do not race engine for faster warmup.
When water temperature is too low, the cylinder walls retard heating of air during compression and delays
ignition. This causes incomplete combustion detonation, excessive exhaust smoke and high fuel consumption.
If engine does not start within 30 seconds, allow starting motor to cool and battery to recover for a minute
or two before trying again.
After warmup, the engine should come up to normal operating temperature after driving or operating the
crane. Under normal conditions, oil pressure should remain in a range of 40 to 60 pounds. Coolant temperature
should be in the range of 170° to 185° F.
AID TO COLD WEATHER STARTING
The correct grade of oil for the prevailing ambient temperature should be used in the crankcase to prevent
hard cranking. The diesel fuel should have a pour point of 10°F less than the lowest expected temperature. In
case of emergency, white kerosene may be added to the fuel to bring the pour point down to the required
temperature in order to prevent clogging of filters and small passages by wax crystals. The addition of kerosene is
NOT recommended for general use.
