OM3043 Operation - Section 3 Operating Instructions Page 30-1 OPERATING INSTRUCTIONS Preparing for Operation permitted, the operator should follow this or similar routine. The safest trucks are those which have been prop- erly 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. 1. Start at left front of truck. While performing the walk around inspection, visually inspect all lights and safety equipment for external dam- age from rocks or misuse. Make sure lenses are clean and unbroken. Safety is Thinking Ahead Prevention is the best safety program.
Prevent a potential accident by knowing the employer's safety requirements, all necessary job site regulations, as well as use and care of the safety equipment on the Komatsu Truck. Only qualified operators or techni- cians should attempt to operate or maintain the Komatsu Truck. Empty the dust pans on the left side air cleaner assemblies. Be sure battery box covers are in place and secure. 2. Move behind the front of the left front tire, inspect the hub and brake assemblies for leaks and any abnormal conditions. Check front wheel hub oil sight gauge for oil level. Safe practices start before the operator gets to the equipment!
Check that all suspension attaching hardware is secure and inspect mounting key area for evi- dence 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 hazard. Always use the personal safety equipment provided 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. 3. With engine stopped, check engine oil level. If dark, turn on service light. 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 to turn off service light, if used. When walking to and from the truck, maintain a safe distance from all machines even if the operator is visible. 5. Inspect anchor end of steering cylinder for proper greasing and for security. 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 bubbles and that inflation appears to be correct.
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 inspection 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. 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 cylin- der for proper greasing, and for security of all parts. Inspect for any hydraulic leaks.
Start at the left front corner of the truck (see illustra- tion, next page), and move in a counter-clockwise direction, front-to-rear, across the rear, and continu- ing forward up the opposite side of the truck to the original starting point. 8. Inspect sight glass on hydraulic tank. With engine stopped and body down, hydraulic fluid should be visible in upper sight glass. If these steps are taken in sequence, and are repeated from the same point and in the same direc- tion before every shift, many potential problems may be avoided, or scheduled for maintenance. UNSCHEDULED downtime and loss of production can be reduced. 9.
Move on around the hydraulic tank and in front of the rear dual tires, inspect the hoist cylinder for any damage and leaks, also that lower guard is in place. Inspect both upper and lower hoist cylinder pins for security, and for proper greasing. Local work practices may prevent an operator from performing all tasks suggested here, but to the extent
