WALK-AROUND CHECK
3
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
q
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.
q
Do not get on or off the machine from the rear. Using this position is dangerous because it is easy to
slip and you cannot be seen from the operator's compartment. Always use the handrail and step at the
side when getting on or off the machine.
If the machine is at an angle, reposition it level before checking.
Perform the following inspections and cleaning every day before starting engine for the day's work.
1.
Check for damage, wear, play in work equipment, cylinders, linkage, and hoses.

any problem is found, repair it.
2.
Remove dirt and debris from around the engine, battery, and radiator.
Check for dirt accumulated around the engine and radiator. Also check for flammable material (dry leaves,
twigs, etc.) around the battery, engine muffler, turbocharger, or other high temperature engine parts. If any dirt
or flammable materials are found, remove them.
3.
Checking engine for leak of water, oil and air
Check the engine for leak of engine oil, leak of water from the cooling system and leak of air from the suction
system. If any leak is found, repair it.
4.
Check for oil leakage of oil from power train case, final drive case, hydraulic tank, hoses, and joints
Check that there is no oil leakage. If any problem is found, repair the place where the oil is leaking.
Check for leakage of oil from the undercover. Check the ground for traces of oil leakage.
