OPERATING PROCEDURES
Revised: October 20053 - 2RT700
Once the pre-start inspection has been completed, the
engine may be started. At ambient temperatures over
32 deg. F. on Cummins Engines, follow the starting
procedure below:
1. Open the governor to the idle position.
2. Move the transmission shift lever to the neutral po-
sition.
3. Put the parking brake switch in the “ON” position.
4. Turn the ignition switch to the “ON” position.
5. Turn the ignition switch to the “START” position to
start the engine.
Release the ignition switch key as soon as the engine
starts. If the engine stalls during the start-up proce-
dure, allow the engine to stop revolving before re-en-
gaging the starter.
Do not engage the starter motor for more than 30 sec-
onds at a time. Should the engine fail to start within 30
seconds, allow the starter motor to cool for 2 minutes
before attempting to start the engine again.
Once the engine is started, check the gauges for prop-
er readings. If the gauges do not register normal read-
ings, stop the engine and determine the cause. Avoid
full Throttle operation when the engine is cold. Always
allow the engine to reach normal operating tempera-
ture before commencing operations.
NOTE: On machines equipped with a turbocharged
engine, the oil pressure gauge MUST register 10 psi
(60 kpa) at idle speed to ensure full lubrication of turbo-
charger.
STARTING THE ENGINE
RATED CAPACITY INDICATOR
The RCI will indicate an overload condition with an au-
dible alarm and the exterior RCI lamp above the cab
door will flash. All boom functions will be disabled ex-
cept boom retract and winch down. Move the load into
an acceptable condition to stop alarms and continue
normal crane operation. (See RCI Section for further
details.)
3RD WRAP
Winch down function will be disabled when less than 3
wraps of rope are available on the winch. You must re-
tract boom or winch up.
OPERATOR’S ARMREST
When Operator’s left arm rest is raised, all functions
are disabled. Lower arm rest to resume normal crane
operation.
ANTI-TWO BLOCK SYSTEM Inspect all anti-two
block switches found on boom, jib and auxiliary sheave
heads for damage. Check the freedom of counter-
weight attached to these switches; and also, that coun-
terweight is attached around correct line of hoisting
cable in the proper manner. Inspect all electrical con-
nections and wires as well as the entire length of cable
attached to the cable reel and it’s connections for evi-
dence of excessive wear, damage or improper installa-
tion. Check spring loaded cable reel for proper tension
and to insure that reel is free to rotate. Verify visual and
audible warning devices by lifting each of the counter-
weights.
NOTE: A warning light will appear on the dash mount-
ed panel and an audible signal will be heard when
switch is in ON position.
