Operation - Section 3
Page 3-6
LOADING
1. Pull into the loading area with caution. Remain at
a safe distance while truck ahead is being loaded.
2. Do not drive over unprotected power cables.
3. When approaching or leaving a loading area,
watch out for other vehicles and for personnel
working in the area.
4. When pulling in under a loader or shovel, follow
''Spotter'' or ''Shovel Operator'' signals. The truck
operator may speed up loading operations by
observing the location and loading cycle of the
truck being loaded ahead, then follow a similiar
pattern.
5. Operator should remain in truck cab with engine
running while truck is being loaded.
Place Transmission Range Selector in ''Neutral''
and apply the Brake Lock Switch.
If operator must leave truck cab during loading,
engine must be shut down and parking brake
applied. DO NOT use emergency brake for parking.
Remain far enough away from truck to avoid being
struck by flying material.
6. When truck is loaded, pull away from shovel as
quickly as possible, but with extreme caution.
HAULING
1. Always stay alert! If unfamiliar with the road, drive
with extreme caution.
2. Govern truck speed by the road conditions,
weather and visibility.
3. Operate truck so it is under control at all times.
4. Use extreme caution when approaching a haul
road intersection. Maintain a safe distance from
oncoming vehicles.
5. Obey all road signs.
6. Always dim headlights when meeting oncoming
vehicles.
7. Maintain a safe distance when following another
vehicle. Never approach another vehicle from the
rear, in the same lane, closer than 15 m (50 ft).
When operating on a down grade, stay at least 30
m (100 ft) away.
8. Before starting down a grade, maintain a speed
that will insure safe operation and provide effec-
tive retarding under all conditions.
When descending a known grade with a loaded
truck, the operator should adjust the speed of the
truck if necessary, to preselect a transmission
gear range, so that operation can be maintained
within the speeds listed on the Retarding Capac-
ity decal located inside the cab on the left front
cab post (Shown below). Either the retarder con-
trol lever or the foot-operated brake pedal can be
used to control the speed of the truck.
Retarder Operation
Two lists are provided on the Retarding Capacity
decal, one a continuous rating and the second a
short-length rating. Both lists are matched to the
truck at maximum Gross Vehicle Weight.
The continuous numbers on the chart indicate the
combination of speeds and grades which the
vehicle can safely negotiate for unlimited time or
distance.
The short-length numbers listed on the chart indi-
cate the combination of speeds and grades which
the vehicle can safely negotiate for three minutes.
These speeds are faster than the continuous val-
ues, reflecting the thermal capacity of various
system components. System components can
accept heating at a higher-than-continuous rate
for a short period of time, beyond which the sys-
tem would become over-temperature.
