Komatsu — Before Starting Engine

OM2026.1 Safety - Section 2 General Safety Page 2-5 PRECAUTIONS DURING OPERATION BEFORE STARTING ENGINE SAFETY AT WORKSITE Before starting the engine, thoroughly check the area for any unusual conditions that could be dangerous. Examine the road surface in the jobsite and determine the best and safest method of operation. Choose an area where the ground is as horizontal and firm as possible before carrying out the operation. If you need to operate on a road, protect pedestrians and cars by designating a person for worksite traffic duty or by installing fences around the worksite. Check the river bed condition, and depth and flow of water before crossing shallow parts of river.

NEVER be in water which is in excess of the permissible water depth. The operator must check personally the work position, roads to be used, and existence of obstacles before starting operations. Always determine the travel roads in the worksite and maintain them so that it is always safe for the machines to travel. FIRE PREVENTION Thoroughly remove wood chips, leaves, paper and other flammable things accumulated in the engine compartment. They could cause a fire. Check fuel, lubrication, and hydraulic systems for leaks. Have any leaks repaired. Wipe up any excess oil, fuel or other flammable fluids. Be sure a fire extinguisher is present and working.

Do not operate the machine near any flame. Do not leave tools or spare parts lying around in the operator’s compartment. They may damage or break the control levers or switches. Always put them in the tool box on the right side of the machine. IN OPERATOR’S CAB Keep the cab floor, controls, steps and handrails free of oil, grease, snow, and excess dirt. Check the seat belt, buckle and hardware for damage or wear. Replace any worn or damaged parts. Always use seat belts when operating your machine. VENTILATION FOR ENCLOSED AREAS If it is necessary to start the engine within an enclosed area, provide adequate ventilation. Exhaust fumes from the engine can KILL.

KEEP MIRRORS, WINDOWS, AND LIGHTS CLEAN Remove any dirt from the surface of the windows or lights to ensure good visibility. Adjust the rear view mirror to a position where the operator can see best from the operator’s seat, and keep the surface of the mirror clean. If any glass should break, replace it with a new part. Check that the machine is equipped with the head lamps and working lamps needed for the operating conditions. Check that all the lamps light up properly.
