OM3037 Operation - Section 3 Operating Instructions Page 3-5 AFTER ENGINE HAS STARTED MACHINE OPERATION SAFETY PRECAUTIONS 1. After engine has started, do not accelerate engine speed or drive truck until low pressure and warn- ing systems are normal, and the coolant tempera- ture is at least 160°F (71°C). 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. 2. Become thoroughly familiar with steering and emergency controls. Test the truck steering in extreme right and left directions. If the steering system is not operating properly, shut engine down immediately.
Determine the steering sys- tem problem and have repairs made before resuming operation. If any of the red warning lights turn “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 indi- cates and have problem corrected before resuming truck operation. 3. Operate each of the truck's brake circuits at least twice prior to operating and moving the truck. These circuits include individual activation from the operator's cab of the service brake, parking brake, and brake lock (also emergency brake, if equipped).
With the engine running and with the hydraulic circuit fully charged, activate each cir- cuit individually. If any application or release of any brake circuit appears sluggish or improper, or if warning alarms are activated on application or release, shut the engine down and notify mainte- nance personnel. Do not operate truck until brake circuit in question is fully operational. 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 acceler- ating engine again.
4. Check gauges, warning lights and instruments before moving the truck to insure proper system operation and proper instrument functioning. Give special attention to braking and steering circuit hydraulic warning lights. If warning lights come on, shut down the engine immediately and deter- mine the cause. 1. Always look to the rear before backing the truck. Watch for and obey ground spotter's hand sign 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. 5. Insure headlights, worklights and taillights are in proper working order. Good visibility may prevent an accident.
Check operation of windshield wiper. 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. 6. When truck body is in dump position, do not allow anyone beneath it unless body-up retaining pin or cable is in place. 3. Check gauges and instruments frequently during operation for proper readings. 7. Do not use the fire extinguisher for any purpose other than putting out a fire! If extinguisher is dis- charged, report the occurrence so the used unit can be refilled or replaced. 4. Observe all regulations pertaining to the job site's traffic pattern. Be alert to any unusual traffic pat- tern.
Obey the spotter's signals. 8. Do not allow unauthorized personnel to ride in the truck. Do not allow anyone to ride on the ladder of the truck. 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. 9. Do not leave truck unattended while engine is run- ning. Shut down engine before getting out of cab. 6. Do not allow engine to run at “Idle” for extended periods of time.
