5-4.
ENGINE STARTUP AND SHUTDOWN.
Normal Engine Starting. The following procedure covers starting the diesel engine
5-4.1
from the carrier cab. Starting the diesel engine from the superstructure follows a similar procedure
except that there must be at least 85 psi (586.1 kPa) in the air system to operate the diesel engine
throttle pedal in the superstructure cab.
WARNING
Before starting the engine, ensure the PARK BRAKE
is applied and the SWING BRAKE switch in the
superstructure cab is ON (brake engaged).
CAUTION
Never crank the engine for more than 30 seconds at
a time. If the engine fails to start after 30 seconds,
allow the starter motor to cool for approximately two
minutes between attempts.
NOTE
The engine will not crank unless the Transmission
Shift Lever (6, Figure 5-1) is in the neutral (N).
Since the superstructure engine throttle is air
operated, the diesel engine should be started from
the carrier cab when the crane air pressure is below
85 psi (586.1 kPa). Otherwise, the engine must idle
until air pressure builds up.
a.
If diesel engine is cold, disengage the main hydraulic pump via the Hydraulic
Pump Disconnect Control (5).
b.
Turn the IGNITION Switch (50) to START and release immediately when the
engine starts. If the diesel engine does not start (less than 30 second
cranking time) and must be re-cranked, wait at least 3 seconds to allow the
starter pinion and ring gear to stop turning.
c.
Check engine instruments for proper indications.
CAUTION
Both air system pressures must be in normal
operating range prior to disengaging parking brake.
Otherwise, service air brakes may not operate
properly when applied.
If oil pressure and/or temperature indicator(s) do not
display proper readings, shut down the engine and
correct the malfunction.
