MACHINE OPERATION SAFETY PRECAUTIONS

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.
1. Always look to the rear before backing the truck. Watch for and obey ground spotter's hand signals 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 com-
partment while truck is in operation.
3. Check 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 traffic 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!
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. 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 similar pattern.
5. When being loaded, operator should stay in truck cab with engine running. Place Selector Switch in "Neutral"
and apply Wheel Brake Lock.
6. When loaded, pull away from shovel as quickly as possible but with extreme caution.
7.
8.
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 seri-
ous damage to wheel motors! If truck does not begin to move within 10
seconds after depressing throttle pedal (Selector Switch in a drive posi-
tion), release throttle pedal and allow wheels to regain traction before
accelerating engine again.
Do not use "Brake Lock" or "Emergency Brake" (if equipped) for park-
ing.With engine stopped, hydraulic pressure will bleed down, allowing
brakes to release!
