General Safety & Operation

A03048

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.

LOADING

1. Pull into the loading area with caution. Remain

at a safe distance while the truck ahead is being
loaded.

2. DO NOT drive over unprotected power cables.
3. When approaching or leaving a loading area,

watch for other vehicles and for personnel work-
ing in the area.

4. When pulling in under a loader or shovel, follow

the spotter or shovel operator signals. The truck
operator may speed up loading by observing the
location and loading cycle of the truck being
loaded ahead. Then follow a similar pattern.

5. When the truck is being loaded, the operator

must stay in the truck cab with the engine on.
Place the selector switch in NEUTRAL, and
apply the brake lock.

6. When loaded, drive away from the shovel

quickly, but with extreme caution.

HAULING

1. Stay alert! Drive with extreme caution. Cab doors

must remain closed at all times if the truck is in
motion or unattended.

2. Obey all road signs. Operate the truck in a con-

trolled manner. Govern the truck speed by the
road conditions, weather, and visibility. Report
haul road conditions immediately. Muddy or icy
roads, pot holes, or other obstructions can pres-
ent hazards.

3. When backing the truck, give the back-up signal

three sounds of the horn. When starting for-
ward, two sounds of the horn. These signals
must be given each time the truck is moved for-
ward or backward.

4. Use extreme caution when approaching a haul

road intersection. Maintain a safe distance from
oncoming vehicles.

5. Maintain a safe distance of 15 m (50 ft) when

following another vehicle. When driving down-
hill, maintain a distance of 30 m (100 ft).

6. DO NOT stop or park on a haul road unless

unavoidable. If you must stop, move the truck to
a safe place, apply the parking brake, and shut
the engine off before leaving the cab. Chock the
wheels securely, and notify maintenance per-
sonnel for assistance.

7. Before starting up or down a grade, maintain a

speed that will ensure safe driving and provide
effective retarding. Refer to the grade/speed
decal in the operator's cab.

8. When operating the truck in darkness, or when

visibility is poor, DO NOT move the truck unless
all the headlights, clearance lights, and tail
lights are on. DO NOT back the truck if the
back-up horn or lights are inoperative. Dim the
headlights when meeting oncoming vehicles.

9. If the emergency steering light and/or low brake

pressure warning light illuminate during opera-
tion, immediately steer the truck to a safe stop-
ping area, away from other traffic.

10. The Statex III w/fuel enhancement system mon-

itors wheel motor, ambient, and static exciter
temperatures. If any one of these values is out-
side the limits established, the Statex III controls
will cause the engine to increase to 1,650 rpm.
Normal engine rpm for haul road/retarding oper-
ation is 1,250 rpm.
