STOP THE ENGINE BEFORE CARRYING OUT INSPECTION AND MAINTENANCE When carrying out inspection and maintenance, always stop on a flat firm road surface where there is no danger of falling rocks, landslides, or floods. Then lower the work equipment to the ground, set the safety lock levers to the LOCK position, and stop the engine. If it is necessary to run the engine when carrying out mainte- nance, such as when cleaning the inside of the radiator, place the safety lock lever at the LOCK position and carry out the operation with two workers. One worker should sit in the operator’s seat so that he can stop the engine immediately if necessary.
He should also be extremely careful not to touch any lever by mistake. Touch the levers only when they have to be operated. The worker carrying out the maintenance should be extremely careful not to touch or get caught in the moving parts.
