Komatsu — OPERATING INSTRUCTIONS

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 before the operator attempts engine start-up. 1. When walking to and from the truck, BE ALERT, remain a safe distance from all other machines even if the operator is visible. 2. Check for any oil or coolant leaks. When checking coolant in radiator, relieve pressure slowly before removing radiator cap. If engine has been running, allow coolant to cool, before removing the fill cap or draining radiator. Serious burns may result if coolant is not allowed to cool. 3.

Check tires for cuts, damage or "bubbles". Check tires for low pressure periodically during shift. If truck has been run on a "flat", the tire must be cooled before parking truck inside . 4. Visually inspect all headlights, worklights and taillights and safety equipment for external damage from rocks or misuse. Make sure lenses are clean. 5. Always use handrails and ladder when mounting or dismounting the truck. Clean ladder and handrails of any foreign material, such as ice, snow, oil and mud. Always mount and dismount the truck facing the truck. Never attempt to mount or dismount the truck while it is in motion. 6.

Dirt or trash buildup, specifically in the operator’s cab, should be cleared. Do not carry tools or supplies in cab of truck or on the deck. 7. Insure steering wheel, controls and pedals are free of any oil, grease or mud. 8. Insure adequate ventilation before start-up if the truck is in an enclosure. Exhaust fumes are dangerous!
