Before starting the engine, look around and under the machine to check for loose nuts and bolts, or leakage of oil,
fuel, or coolant, and check condition of the work equipment and hydraulic system. Also check for loose wiring,
play, and accumulation of dust at places with high temperatures.
WARNING

Leakage of oil or fuel, or accumulation of flammable material around high temperature parts, such as
the engine muffler or turbocharger, may cause fire.
Check carefully, and if any abnormality is found, repair it or contact your Komatsu distributor.
