OM3020.1 12/99 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. 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 truck. Only qualified operators or technicians should attempt to operate or maintain the Komatsu Truck.
Safe practices start before the operator gets to the equipment! 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. When walking to and from the truck, maintain a safe distance from all machines even if the operator is visible.
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. 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, or scheduled for maintenance. UNSCHEDULED downtime and loss of production can be reduced. 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. ! DANGER ! HIGH VOLTAGE MAY BE PRESENT ON THIS TRUCK! DO NOT OPEN ANY ELECTRICAL CABINET DOORS ON THIS TRUCK WHEN THE ENGINE IS RUNNING!
NEVER CLIMB ON ANY POWER CABLES OR USE POWER CABLES FOR HANDHOLDS OR FOOTHOLDS, UNLESS THE ENGINE HAS BEEN SHUT DOWN AND SYSTEM HAS BEEN VERIFIED AT “REST”! 1. Start at left front of truck. While performing the walk around inspection, visually inspect all lights and safety equipment for external damage from rocks or misuse. Make sure lenses are clean and unbroken. 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 that all suspension attaching hardware is secure and inspect mounting key area for evidence of wear. Check that the suspension extension (exposed piston rod) is correct, and that there are no leaks. 3. With engine stopped, check engine oil level. If dark, turn on service light. 4. Inspect 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. 5. Inspect anchor end of steering cylinder for proper greasing and for security.
