3. Check the gauges, warning lights, and instru-
ments before moving the truck to ensure proper
system operation and proper instrument func-
tioning. Observe the braking and steering circuit
hydraulic warning lights. If the warning lights
come on, shut the engine off immediately and
determine the cause.
4. Ensure the headlights, work lights, and taillights
are in proper working order. Good visibility may
prevent an accident. Check the operation of the
windshield wipers.
5. When the truck body is in the dump position,
DO NOT allow anyone beneath it unless the
body-up retaining pin or cable is in place.
6. DO NOT allow unauthorized personnel to ride
in the truck. DO NOT allow anyone to ride on
the stairs or ladder of the truck.
7. DO NOT leave the truck unattended while the
engine is on. Shut the engine off, and apply the
parking brake 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.
DO NOT use the brake lock for parking. With the
engine stopped, hydraulic pressure will bleed-
down, allowing the brakes to release!
8. Check the brake lock performance periodically
for safe loading and dumping.
9. Proceed slowly on rough terrain to avoid deep
ruts or large obstacles. Avoid traveling close to
the soft edges and the edge of the fill area.
10. Truck operation requires concentrated effort by
the driver. Avoid distractions of any kind while
operating the truck.
11. Before driving the truck, ensure the tires are
properly inflated. If the truck has been driven
with an under-inflated tire, do not park the truck
inside a building until the tire has cooled to
ambient temperature.
