MACHINE OPERATION SAFETY PRE-
CAUTIONS
After the truck engine is started and all systems are
functioning properly, the operator must follow all local
safety rules to insure safe machine operation.
If any of the red warning lights come "On" or if
any gauge reads in the red area during truck
operation, a malfunction is indicated. Stop truck
as soon as safety permits, shut down engine if
problem indicates and have problem corrected
before resuming truck operation.
Operating truck with stalled or free spinning
wheel motors may cause serious damage to
wheel motors! If truck does not begin to move
within 10 seconds after depressing throttle pedal
(Selector Switch in a drive position), release
throttle pedal and allow wheels to regain traction
before accelerating engine again.
1. Always look to the rear before backing the truck.
Watch for and obey ground spotter's hand sig-
nals before making any reverse movements.
Sound the warning horn (3 blasts). Spotter
should have a clear view of the total area at the
rear of the truck.
2. Operate the truck only while properly seated
with seat belt fastened. Keep hands and feet
inside the cab compartment while truck is in
operation.
3. Check gauges and instruments frequently dur-
ing 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 haul road conditions
and slow the truck in any congested area. Keep
a firm grip on steering wheel at all times.
6. Do not allow engine to run at "Idle" for extended
periods of time.
7. Check parking brake periodically during shift.
Use parking brake ONLY for parking. Do not
use park brake for loading / dumping. Do not
attempt to apply parking brake while truck is
moving!
A3-24
Do not use "Brake Lock" or "Emergency Brake"
(if equipped) for parking. With engine stopped,
hydraulic pressure will bleed down, allowing
brakes to release!
MACHINE OPERATION ON THE HAUL
ROAD
General Safety and Operating Instructions
8. Check brake lock performance periodically for
safe loading and dump operation.
9. Proceed slowly on rough terrain to avoid deep
ruts or large obstacles. Avoid traveling close to
soft edges and the edge of fill area.
10. Truck operation requires concentrated effort by
the driver. Avoid distractions of any kind while
operating the truck.
1. Always stay alert! If unfamiliar with the road,
drive with extreme caution. Cab doors should
remain closed at all times if truck is in motion or
unattended.
2. Obey all road signs. Operate truck so it is under
control at all times. Govern 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. Initial propulsion with a loaded truck should
begin from a level surface whenever possible,
but when there are circumstances where start-
ing on a hill or grade cannot be avoided, refer to
the "STARTING ON A GRADE WITH A
LOADED TRUCK" procedure.
4. When backing the truck, give back-up signal
(three blasts on the horn); when starting for-
ward, two blasts on the horn. These signals
must be given each time the truck is moved for-
ward or backward.
5. Use extreme caution when approaching a haul
road intersection. Maintain a safe distance from
oncoming vehicles.
6. Maintain a safe distance when following another
vehicle. Never approach another vehicle from
the rear, in the same lane, closer than 50 ft. (15
m). When driving on a down grade, this dis-
tance should not be less than 100 ft. (30 m).
