OM3006.1 04/98 Operation - Section 3 Operating Instructions Page 3-1 OPERATING INSTRUCTIONS PREPARING FOR OPERATION 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 operator before attempting to start the engine. 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 routine. SAFETY IS THINKING AHEAD 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. Prevention is the best safety program. Prevent a po- tential accident by knowing the employer’s safety re- quirements and all necessary job site regulations, as well as use and care of the safety equipment on the KOMATSU 530M Haulpak Truck. Only qualified operators or technicians should attempt to operate or maintain the 530M Truck. 2. Move behind the front of the left front tire, inspect the hub and the oil disc 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 and inspect for evidence of wear. Check that the suspension extension (exposed piston rod) 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 haz- ard. 3. With engine stopped, check engine oil level. Check that the engine oil filters or oil lines to filters are not leaking. 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. 4. Inspect fan and air conditioner belts for correct tension, obvious wear, and tracking. Inspect fan guard for security and condition. When walking to and from the truck, maintain a safe distance from all machines even if the opera- tor is visible. 5. 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. 6. 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 the tie-rod pivots and steer- ing cylinder for proper greasing, and for security of all parts. Inspect for any hydraulic leaks. At The Truck - Ground Level Walk Around Inspection At the beginning of each shift, a careful walk around inspection of the truck should be made before the operator attempts engine start-up. A walk around in- spection is a systematic ground level inspection of the truck and its components to insure that the truck is safe to operate before entering the operator’s cab. 7. Inspect sight glass for transmission oil level. Check pumps on front of transmission for leakage and that all parts are secure.
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. 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. 8. Move to the side of the hydraulic tank and check the hydraulic fluid level for both the hydraulic tank and brake cooling oil. Oil should be visible in sight glass with engine stopped and body down. 9.
Move on around the hydraulic tank and in front of the rear dual tires, inspect the hoist cylinder for any damage and leaks. Inspect both upper and lower hoist cylinder pins for security, and for proper greasing. If problems or potential problems are found during the ‘‘walk-around’’, be sure to notify maintenance. Vehicle breakdowns and UNSCHEDULED downtime and loss of production can be reduced.
