Method for Lubricating Drive Shaft

Steps for Lubricating Drive Shaft

Check for leakage of water and oil around the water pump. If any problem is found, ask your Komatsu distributor to perform disassembly, repair, or replacement.

Method for Checking Starting Motor

Ask your Komatsu distributor to have the starting motor checked. If the engine is started frequently, have this inspection performed every 1000 hours.

Method for Checking and Adjusting Air Conditioner Compressor

Warning: Immediately after the engine is stopped, its parts and oil are still very hot, and may cause burn injury. Wait for the temperature to go down, and then start the work.

Warning: When removing the oil filler cap, the oil may spurt out. Turn it slowly to release the internal pressure, then remove it carefully.

Warning: Immediately after the engine is stopped, the parts are still very hot. Do not replace the filter immediately. Wait for all parts to cool down before starting the work.

Warning: High pressure is generated inside the engine fuel piping system when the engine is running. When replacing the filter, wait for at least 30 seconds after stopping the engine to let the internal pressure go down before replacing the filter.

Warning: Do not bring any open flame close.

Notice: Komatsu genuine fuel filter cartridges use a special filter that has highly efficient filtering ability. When replacing the parts, Komatsu recommends using Komatsu genuine parts.

Notice: The common rail fuel injection system used on this machine consists of more precise parts than those in the conventional injection pump and nozzles. If any cartridge other than a Komatsu genuine filter cartridge is used, dust or dirt may get in and cause problems with the injection system. Never use a substitute.

Notice: When performing inspection and maintenance of the fuel system, be careful not to let any foreign material get in, more than ever before. If dust sticks to the fuel system, wash it off thoroughly with fuel.

Open the engine side cover (1) on the right side of the machine.

METHOD FOR CHECKING, CLEANING AND REPLACING AIR CLEANER

• When using compressed air, there is a danger that dirt may scatter and cause personal injury.

Always wear the protective eyeglasses, dust mask, or other protective equipment.

• When removing the outer element from the air cleaner body, it is dangerous to pull it out by force.

When working in high places or where the foothold is poor, be careful not to fall because of the reaction when pulling out the outer element.

• Do not clean the element before the yellow piston shown in dust indicator (2) display enters the red (7.5 kPa {0.08 kg/cm2}) position.

If the element is cleaned frequently before the yellow piston of the dust indicator enters the red (7.5 kPa {0.08 kg/cm2}) position, the air cleaner will not be able to display its performance fully, and the cleaning efficiency will also go down.
