is released before the engine starts, turn the key
switch “OFF” and repeat the procedure.
4. Follow steps 5 -7 as listed in “Starting The
Engine”.
Refer to the engine operator manual for additional cold
starting procedures.
If the battery becomes discharged and has insufficient
power to start the engine, jumper cables can be used
for starting assistance. Refer to the jump starting
instructions in the
Service and Storage chapter of this
manual for safe jump starting procedures.
STOPPING
The following procedure is the recommended
sequence for stopping the machine:
1. Bring the machine to a stop on a level surface.
Avoid parking on a slope, but if necessary park
across the slope and block the wheels.
2. Fully retract the boom and lower the attachment
to the ground.
3. Idle the engine for at least 2 minutes for gradual
cooling.
IMPORTANT: If and Exhaust Filter Cleaning has
just been performed, increase the engine idle time
to 4 minutes.
4. Place controls in neutral. Apply the parking brake.
5. Turn the ignition switch key to the “OFF” posi-
tion. Remove the key.
6. Unfasten the seatbelt, and grasp the handholds
while climbing out of the operator’s compart-
ment.
FIRST TIME OPERATION
Make sure the engine is warm, and then go through the
following procedures:
Place the travel lever in Forward or Reverse and select
a speed range. Switch off the parking brake and move
ahead slowly, while testing the steering and brakes.
Stop and operate all boom, attachment tool functions
and frame leveling controls, checking for smooth
response.
Apply the service brakes, stop the machine and move
the travel lever to the opposite direction.
Shifting to the next higher gear may be done at any
engine speed while the machine is in motion.
DO NOT overspeed the engine when down-shifting.
Allow the machine to slow down before shifting to the
next lower gear.
ENGINE SHUTDOWN PROTECTION
The engine is equipped with a WARNING and SHUT-
DOWN feature to warn of low engine oil pressure and
high engine coolant temperature. If the problem is not
corrected, the engine power will be reduced automati-
cally, or the engine will shut down.
Engine Oil Pressure
There are two low oil pressure protection features:
Low Oil Pressure WARNING, and Low Oil Pressure
SHUTDOWN.
At the Low Oil Pressure WARNING set-point, the
warning lamp in the engine override switch and the
amber lamp in the exhaust filter gauge will flash and a
slow engine power derate will begin. But if the oil
pressure rises above the Low Oil Pressure WARNING
set-point, power will slowly increase until the engine is
back to full power. The lamp in the switch and exhaust
filter gauge will continue to flash until the power has
returned to normal, even if the fault condition has been
corrected and the recovery is in process.
At the Low Oil Pressure SHUTDOWN set-point, the
lamp in the engine override switch and the amber lamp
in the exhaust filter gauge will light continously, and a
fast engine power derate will begin. If the oil pressure
does not rise above the SHUTDOWN set-point within
30 seconds, the engine will shut down. However, if the
oil pressure rises above the Low Oil Pressure SHUT-
DOWN set-point within 30 seconds, then the power
derate speed will revert to the Low Oil Pressure
WARNING speed of reaction.
CAUTION
Be sure the area used for test-running is clear
of spectators and obstructions. Initially, oper-
ate the machine with an empty attachment
tool.
