OM3043 06/06 Operation - Section 30 Operating Instructions Page 30-1 OPERATING INSTRUCTIONS PREPARING FOR OPERATION 2. Move behind the front left tire. Check the hub and brake assemblies for leaks, and any abnor- mal wear or signs of damage. Check the oil level in the front wheel hub sight gauge. Refill, if necessary. The safest trucks are those which have been prop- erly prepared for operation. At the beginning of each shift, a careful inspection of the truck must be com- pleted by the operator before starting the engine. 3. With the engine stopped, check the engine oil level. If necessary, use the service light to illu- minate the area.
Ensure the light is turned off when the inspection of this area is complete. SAFETY IS THINKING AHEAD Prevention is the best way to avoid an accident. Pre- vent potential accidents by knowing the employer's safety requirements and all necessary job site regu- lations. In addition, know the proper use and care of all the safety equipment on the truck. Operators or technicians must be qualified to operate or maintain a Komatsu truck. 4. Inspect the fan and air conditioner belts for cor- rect tension and tracking. Also, check for belt wear or damage. Verify the fan guard bolts are installed and properly tightened. Safe practices start before the operator gets to the truck!
Refer to Section 20, General Safety, for safety guidelines. 5. Ensure the anchor end of the steering cylinder pin is properly greased and tightened. 6. Move outboard of the front wheel and inspect the attaching lugs/wedges to ensure they are properly tightened. Replace any parts that are missing. WALK-AROUND INSPECTION At the beginning of each shift, perform a careful walk- around inspection of the truck before engine start-up. A walk-around inspection is a ground level check of the truck and its components to ensure the truck is safe to operate. Inspect the tires for damage. Check for proper inflation. 7. Move behind the rear of the front wheel.
Ensure the suspension protective boot is in good condi- tion. Verify all suspension attaching hardware bolts are completely tightened. Inspect the mounting key area for evidence of wear. Verify the suspension extension (exposed piston rod) is correct. Check for leaks. Start at the left front corner of the truck (see illustra- tion, next page.) Move in a counterclockwise direc- tion, around the truck, and back to the starting point. Inspection of the truck before every shift can help avoid many potential problems. Downtime and loss of production can be reduced by scheduled maintenance. Check for leaks around the hub and brakes. Also, check for any unusual wear conditions or damage.
Local work practices may prevent an operator from performing all tasks suggested here. To the extent permitted, the operator must follow this or a similar routine. Ensure the rod end of the steering cylinder is properly greased. Verify all mounting hardware is properly tightened. Check for any hydraulic leaks. 1. Start at the left front of the truck. During the walk-around inspection, visually inspect all lights and safety equipment for external dam- age. Ensure all light housing lenses are clean and unbroken. Empty the dust pans on the left side air clean- ers. Ensure the battery box covers are in place and securely fastened.
