Before starting the engine, walk around the machine and look at the underside of chassis for anything unusual like
loose bolts and nuts, leakage of fuel, oil and coolant. Also check the condition of the work equipment and the
hydraulic system.
Also check for loose wiring, play, and collection of dust at places that reach high temperature.
WARNING
q
Always hang a warning sign on the work equipment control levers.
q
Spilled fuel or oil or accumulation of flammable materials around the battery or other high-temperature
parts of the engine, such as the engine muffler or turbocharger will cause fire on the machine. Always
check thoroughly and repair any problems or contact your Komatsu distributor.
