Before starting the engine, walk around the machine and look to the underside of chassis for anything unusual like looseness of the bolts and nuts, leakage of fuel, oil and cooling water. Also check the condition of the work equip- ment and the hydraulic system.

Check also for loose wiring, play, and collection of dust at places which reach high temperature.

WARNING

Remove any flammable materials from around the battery or engine muffler, turbocharger, or other high temperature engine parts. Leakage of fuel or oil will cause the machine to catch fire. Check carefully, and be sure to repair any abnormalities, or please contact your Komatsu distributor.

Always carry out the items in this section before starting the engine each day.

1. Check for damage, wear, play in work equipment, cylinders, linkage and hoses.

Check that there are no cracks, excessive wear, or play in the work equipment, cylinders, linkage or hoses. If any abnormality is found, repair it.

2. Remove dirt and dust from around engine, battery and radiator.

Check if there is any dirt or dust accumulated around the engine or radiator. Check also if there is any flam- mable material (dead leaves, twigs, etc.) accumulated around the battery or high temperature engine parts, such as the engine muffler or turbocharger. Remove all such dirt or flammable material.

3. Check for coolant or oil leakage around engine.

Check that there is no oil leakage from the engine or coolant leakage from the cooling system. If any abnor- mality is found, repair it.
