PRECAUTIONS FOR MAINTENANCE
Do not perform any inspection and maintenance operation that are not found in this manual.

CHECK SERVICE METER READING

Check the service meter reading every day to see if the maintenance time has come for any necessary mainte-
nance item to be performed.

KOMATSU GENUINE REPLACEMENT PARTS

Komatsu recommends using Komatsu genuine parts specified in Parts Book as replacement parts.

KOMATSU GENUINE LUBRICANTS

For lubrication of the machine, Komatsu recommends using Komatsu genuine lubricants. Moreover use oil of
the specified viscosity according to the ambient temperature.

ALWAYS USE CLEAN WASHER FLUID

Use automobile window washer fluid, and be careful not to let any dirt get into it.

FRESH AND CLEAN LUBRICANTS

Use clean oil and grease. Also, keep the containers of the oil and grease clean. Keep foreign materials away
from oil and grease.

CHECK DRAINED OIL AND USED FILTER

At the replacement of the filters when oil is changed, check the old oil and filters for metal particles and foreign
materials. If large quantity of metal particles or foreign materials are found, always report to the person in
charge, and perform suitable action.

PRECAUTIONS FOR REFILLING OIL OR FUEL

If your machine is equipped with a strainer, do not remove it while filling oil or fuel.

PRECAUTIONS FOR ADDING DEF

Do not remove the strainer while adding DEF.
It is recommended to use a nozzle having a diameter and a length specified by ISO 22241-4 and an auto stop
function to add DEF.

WELDING INSTRUCTIONS

• When conducting weld repair, turn the starting switch to OFF position and, after confirming that the system
operating lamp is turned off, set the battery disconnect switch key to OFF position and pull it out.
• Do not apply a voltage higher than 200 V continuously.
• Connect grounding cable within 1 m of the area to be welded. If grounding cable is connected near instru-
ments, connectors, etc., the instruments may malfunction.
• Prevent seals, bearings or bushings from entering the space between the weld zone and grounding point.
Seals and the like can cause damage to the nearby parts by catching fire from sparks.
• Do not use the area around the work equipment pins or the hydraulic cylinders as the grounding point.
Sparks generated there can damage the plated portion.

DO NOT DROP THINGS INSIDE MACHINE

• When opening the inspection windows or the oil filler port of the tank to perform inspection, be careful not to
drop nuts, bolts, or tools inside the machine.
If such things are dropped inside the machine, it may cause damage and/or malfunction of the machine,
and will lead to failure. If anything drops, be sure to take it out.
• Do not put unnecessary things in your pockets. Carry only things which are necessary for inspection.
