OM3070 Operation - Section 30 Operating Instructions Page 30-1 OPERATING INSTRUCTIONS PREPARING FOR OPERATION 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. High voltage may be present on this truck! DO NOT open any electrical cabinet doors on this truck while 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 the system has been verified to be de-energized by a qualified electrician.
SAFETY IS THINKING talkAHEAD 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. 3. 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. Safe practices start before the operator gets to the truck! Refer to Section 20, General Safety, for safety guidelines.
WALK AROUND INSPECTION 4. With the engine (5, Figure 30-1) stopped, check the engine oil level. If necessary, use the ser- vice light to illuminate the area. Ensure the light is turned off when the inspection of this area is complete. 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. 5. Inspect the fan and air conditioner belts for cor- rect tension and tracking. Also, check for belt wear or damage.
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. Verify the fan guard bolts are installed and properly tightened. Inspection of the truck before every shift can help avoid many potential problems. Downtime and loss of production can be reduced by scheduled maintenance. 6. Ensure the anchor end of the steering cylinder pin is properly greased and tightened. 7. Move outboard of the front wheel and inspect the attaching lugs/wedges to ensure they are properly tightened. Replace any parts that are missing.
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. Inspect the tires for damage. Check for proper inflation. 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. 2. Empty the dust pans on the left side air clean- ers. Ensure the battery box covers are in place and securely fastened. Inspect the battery box cover for damage. Verify it is securely attached.
