CHECK BEFORE STARTING ENGINE, ADJUST
WALK-AROUND CHECK
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
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.
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, hoses
Check for cracks, excessive wear, play in wotk equipment, cylinders, linkage, and hoses. If any abnormality is
found, repair it.
2.
Remove dirt and debris from around the engine, battery, and radiator
Check for dirt accumulated around the engine or radiator. Also check for flammable material (dry leaves, twigs,
grass, etc.) accumulated around the battery, engine muffler, turbocharger, or other high temperature engine
parts. If any dirt or flammable materials are found, remove them.
3. Check for coolant and oil leakage around the engine
Check for oil leakage from the engine and coolant leaks from the cooling system. If any abnormality is found,
repair it.
4.
Check for leakage of oil from power train case, final drive case, hydraulic tank, hose, joints
Check that there is no oil leakage. If any abnormality 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.
5.
Check the undercarriage (track, sprocket, idler, guard) for damage, wear, loose bolts, or leakage of oil from
rollers
If any damage, wear, or oil leakage is found, repair the problem and tighten the bolts.
6. Check for damage to handrail and loose bolts
Repair any damage and tighten any loose bolts.
7. Check for damage to gauges, lamps on the instrument panel, and loose bolts
Check for damage to the panel, gauges, and lamps. Replace any damaged parts. Clean off any dirt on the
surface.
