BEFORE STARTING ENGINE

WALK-AROUND CHECKS
Before starting the engine, look around the machine and under the machine to check for loose nuts or bolts, or
leakage of oil, fuel, or coolant, and check the condition of the work equipment and hydraulic system. Check also
for loose wiring, play, and accumulation of dust at places which reach high temperatures.
If you open the engine hood, then fix the hood in position with hood stopper.
Remove any flammable materials from around the battery or engine muffler, 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 check the items in this section before starting the engine each day.

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, grass, etc.) accumulated around the battery or high temperature engine
parts, such as the engine muffler or turbocharger. Remove all such dirt or flammable material.
