OM3037 Operation - Section 3 Operating Instructions Page 3-1 OPERATING INSTRUCTIONS PREPARING FOR OPERATION Local work practices may prevent an operator from performing all tasks suggested here, but to the extent permitted, the operator should follow this or similar rou- tine. The safest trucks are those which have been properly prepared for operation. At the beginning of each shift, a careful check of the truck should be made by the oper- ator before attempting to start the engine. 1. Start at left front of truck (see illustration, next page). While performing the walk around inspec- tion, visually inspect all lights and safety equip- ment for external damage from rocks or misuse.
Make sure lenses are clean and unbroken. SAFETY IS THINKING AHEAD Prevention is the best safety program. Prevent poten- tial accidents by knowing all of the employer's safety requirements, all necessary job site regulations, as well as the use and care of the safety equipment on the truck. Only qualified operators or technicians should attempt to operate or maintain the truck. Empty the dust pans on the left side air cleaner assemblies. 2. Move behind the front of the left front tire, inspect the hub and brake assemblies for leaks and any abnormal conditions. Safe practices start before the operator gets to the equipment!
Check that all suspension attaching hardware is secure, the suspension extension is correct, and that there are no leaks. Wear the proper clothing. Loose fitting clothing, unbuttoned sleeves and jackets, jewelry, etc., can catch on a protrusion and cause a potential hazard. Always use the personal safety equipment pro- vided for the operator such as hard hat, safety shoes, safety glasses or goggles. There are some conditions when protective hearing devices should also be worn for operator safety. When walking to and from the truck, maintain a safe distance from all machines even if the operator is visible. 3. With engine stopped, swing access ladder down.
If dark, turn on service light located to the right, just above ladder by hand rail. Check engine oil level. 4. Inspect fan and air conditioner belts for correct tension, obvious wear, and tracking. Inspect fan guard for security and condition. When leaving this point, be sure ladder is up and secure, and turn off service light(s), if used. 5. Inspect anchor end of steering cylinder for proper greasing and for security. At The Truck - Ground Level Walk Around Inspection 6. Move outboard of the front wheel, and inspect attaching lugs/wedges to be sure all are tight and complete. Check tires for cuts, damage or “bub- bles” and that inflation appears to be correct.
Check sight glass for front wheel oil level. At the beginning of each shift, a careful walk around inspection of the truck should be made before the oper- ator attempts engine start-up. A walk around inspection is a systematic ground level inspection of the truck and its components to insure that the truck is safe to oper- ate before entering the operator's cab. 7. Move behind the rear of the front wheel, inspect for leaks at hub or brakes or any unusual condi- tions. Inspect suspension hardware to be sure it is all in place. Inspect live end of steering cylinder for proper greasing, and for security of all parts. Inspect for any hydraulic leaks.
Start at the left front corner of the truck (see illustration, next page), and move in a counter-clockwise direction, front-to-rear, across the rear, and continuing forward up the opposite side of the truck to the original starting point. Swing hydraulic tank inspection ladder down. Inspect sight glass on hydraulic reservoir, engine should be stopped and body down, and fluid should appear in lower sight glass. If these steps are taken in sequence, and are repeated from the same point and in the same direction before every shift, many potential problems may be avoided, or scheduled for maintenance. UNSCHEDULED down- time and loss of production can be reduced. 8.
Before leaving hydraulic tank be sure that ladder is up and secure.
