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. AFTER ENGINE HAS STARTED 1. 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 re- suming 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 indi- cates and have problem corrected before resum- ing truck operation. 2. 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, retarder control lever, parking brake switch, brake lock switch, and emergency brake switch. Activate each circuit individually with the engine running and with the hydraulic circuit fully charged. 1. Always sound the warning horn before moving the truck. When backing the truck, give back-up sig- nal (three blasts on horn); when starting forward, two blasts on horn. These signals must be given each time the truck is moved forward or back- ward. Look to the rear before backing the truck. Watch for and obey ground spotter’s hand signals before making any reverse movements.
Spotter should have a clear view of the total area at the rear of the truck. If any application or release of any brake circuit does not appear proper or if sluggishness is ap- parent on application or release, shut the engine down and notify maintenance personnel. Do not operate truck until brake circuit in question is fully operational. 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. Keep a firm grip on steering wheel at all times. 3. 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 warning lights. If warning lights come on, shut down the engine immediately and determine the cause. 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 pat- tern. Match the truck speed to haul road condi- tions and slow the truck in any congested area. Obey the spotter’s signals at shovel and dump. 4. Insure headlights, worklights and taillights are in proper working order. Good visibility may prevent an accident. Check operation of windshield wiper and washer. 5.
Do not allow engine to run at ‘‘Idle’’ for extended periods of time. 6. Check parking brake periodically during working shift. Use parking brake for parking only . Do not attempt to apply parking brake while truck is moving! 5. When truck body is in dump position, do not allow anyone beneath it, unless body-up retaining de- vice is in place. 6. Do not use the fire extinguisher for any purpose other than putting out a fire! If extinguisher is discharged, report the occurrence so the used unit can be refilled or replaced. 7. Apply the Brake Lock Switch at the shovel and dump areas. 8. Proceed slowly on rough terrain to avoid deep ruts or large obstacles.
Avoid traveling close to soft edges and the edge of fill area. 7. Do not allow unauthorized personnel to ride in the truck. Do not allow anyone to ride on the ladder or on the deck of the truck. 9. Truck operation requires concentrated effort by the driver. Avoid distractions of any kind while operating the truck. 8. Do not leave truck unattended while engine is running.
