OPERATING CONTROLS AND PROCEDURES RT770E OPERATOR MANUAL
3-26 Published 04-04-2017, Control # 446-09
Use the correct grade of oil for the prevailing temperature in
the crankcase to prevent hard cranking. Diesel fuel should
have a cloud point of 6°C (10°F) less than the lowest
expected temperature. In case of emergency, white
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. The addition of
kerosene is NOT recommended for general use.
Battery Disconnect Switch
Ensure Battery Disconnect Switch handle (1) (Figure 3-15) is
in the ON position (handle shown in the OFF position)
Warm Engine
NOTE: The engine ECM monitors the engine and, under
certain conditions, cycles the air heater on and off
at start-up and during operation.
The engine is equipped with an electric air heater grid at the
air inlet elbow to aid in cold starting and reduce white smoke
at start-up. In the preheat mode, the engine should not be
cranked until the Wait-to-Start lamp turns off.
1. Ensure the parking brake is set to On, position the
transmission to neutral, and depress the service brake
foot pedal.
NOTE: The engine will not crank unless the transmission
shift lever is in neutral and the service brake foot
pedal is depressed.
The buzzer will sound upon turning the Ignition
Switch to START and turn off after proper hydraulic
oil pressure is reached.
2. Turn the Ignition switch to START and release
immediately when the engine starts. Do not push or hold
the throttle down. The ECM will automatically provide
the proper amount of fuel to start the engine.
3. Immediately check the engine instruments and warning
lights for proper indication after starting.
4. Allow the engine to warm up at least five minutes before
applying a load. Do not race the engine for a faster warm
up.
Cold Engine
NOTE: The engine ECM monitors the engine and, under
certain conditions, cycles the air heater on and off
at start-up and during operation.
The engine is equipped with an electric air heater grid at the
air inlet elbow to aid in cold starting and reduce white smoke
at start-up. In the preheat mode, the engine should not be
cranked until the Wait-to-Start lamp turns off.
1. Prior to starting a cold engine, ensure the Crane
Function switch is positioned to OFF.
2. Ensure the parking brake is set and position the
transmission in neutral.
NOTE: The engine will not crank unless the transmission is
in neutral.
CAUTION
Machine Damage Hazard!
Never crank the engine for more than 30 seconds during
an attempted start. If the engine fails to start after 30
seconds, stop and allow the starter motor to cool for
approximately two minutes before attempting another
start.
If the engine fails to start after four attempts, correct the
malfunction before attempting further starts.
CAUTION
Engine Damage Hazard!
If any warning light stays on or indicator(s) do not display
proper readings, shut down the engine and correct the
malfunction before resuming operation.
WARNING
Risk of Explosion!
Do not spray starting fluid into the air inlet. The spray will
contact the heater elements and could explode causing
personal injury.
