Operating Instructions

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
present 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 con-
trols will cause the engine to increase to 1650
rpm. Normal engine rpm for haul road/retarding
operation is 1250 rpm.
11. When the maximum truck speed is reached,
haul trucks equipped with Statex III w/fuel
enhancement (fuel saver) system will experi-
ence a decrease in engine rpm.
NOTE: This is different from trucks equipped with
Statex II or Statex III without fuel enhancement,
which increase rpm upon reaching the speed limit.

PASSING

1. DO NOT pass another truck on a hill or blind
curve!
2. Before passing, ensure the road ahead is clear.
If a disabled truck is blocking your lane, slow
down and pass with extreme caution.
3. Use only the areas designated for passing.
