7. Shut the engine off by using the engine stop
button located on the center console. Leave the
key switch in the ON position. This allows the
steering accumulators to retain their hydraulic
charge.
q If the warning light and buzzer do activate,
turn the key switch OFF and notify
maintenance personnel. DO NOT operate
the truck until the problem is corrected.
q If the steering accumulators are adequately
charged, the low steering pressure warning
light and the low accumulator precharge
warning light will not illuminate. Continue to
the next step.
8. Turn the steering wheel from stop to stop. The
front wheels must turn fully to the left and to the
right. Eventually, the low steering pressure
warning light will illuminate and the warning
buzzer will sound. This is normal.
If the front wheels cannot be turned fully to the
left and right, or if the warning light and buzzer
do not activate, immediately notify maintenance
personnel. DO NOT operate the truck until the
problem is corrected.
If the truck passes this test, the emergency steering
system is functioning properly.

Additional Guidelines

1. When the truck body is raised, DO NOT allow
anyone below it unless the body-up retaining
cable is in place.
2. DO NOT use the fire extinguisher for any pur-
pose other than putting out a fire! If an extin-
guisher is discharged, report the occurrence so
the used unit can be refilled or replaced.
3. DO NOT allow unauthorized personnel to ride
in the truck. DO NOT allow anyone to ride on
the ladder or outside of the truck cab. Passen-
gers must be belted into the passenger seat
during travel.
DO NOT leave the truck unattended while the engine
is running. Move the directional control lever to
PARK, then shut the engine off before getting out of
the cab.
MACHINE OPERATION SAFETY
PRECAUTIONS
After the truck engine is started and all the systems are
functioning properly, the operator must follow all the
local safety rules to ensure safe machine operation.
If any of the red warning lights come on, or if any
gauge reads in the red area during truck opera-
tion, a malfunction is indicated. Stop the truck as
soon as safety permits, shut the engine off, and
have the problem corrected before resuming
truck operation.
Operating the truck with stalled or free spinning
wheel motors may cause serious damage to the
wheel motors! If the truck does not begin to move
within 10 seconds after depressing the throttle
pedal (selector switch in a drive position), release
the throttle pedal. Allow the wheels to regain trac-
tion before accelerating the engine again.
1. Look to the rear before backing the truck.
Watch for and obey the ground spotter's hand
signals before reversing. Sound the warning
horn three times. The spotter must have a clear
view of the total area at the rear of the truck.
2. Operate the truck only while properly seated
with the seat belt fastened. Keep hands and
feet inside the cab compartment while the truck
is in operation.
3. Check the gauges and instruments frequently
during operation for proper readings.
4. Observe all regulations pertaining to the job
site's traffic pattern. Be alert to any unusual traf-
fic pattern. Obey the spotter's signals.
5. Match the truck speed to the haul road condi-
tions. Slow the truck in congested areas. Keep a
firm grip on the steering wheel at all times.
6. DO NOT allow the engine to idle for extended
periods of time.
7. Check the parking brake periodically during the
shift while the truck is stopped. Use the parking
brake only for parking. DO NOT use the parking
brake for loading/dumping.
