LONG-TERM STORAGE

LONG-TERM STORAGE

BEFORE STORAGE

When putting the machine in storage for more than one month, do as follows.
After every part is washed and dried, the machine shall be housed in a dry building. Never leave it outdoors. In
case it is indispensable to leave it outdoors, park the machine on the flat ground and cover it with canvas etc.
Completely fill the fuel tank, lubricate and change the oil before storage.
Apply a thin coat of grease to metal surface of the hydraulic piston rods and the idler adjusting rods.
Disconnect the negative terminals of the battery and cover it, or remove it from the machine and store it sepa-
rately.
If the ambient temperature is expected to drop below 0ºC, always add antifreeze to the cooling water.
1. Place all control levers at the neutral position, operate the safety lever and parking lever to the LOCK posi-
tion, then move the fuel control dial to the low idling position.

DURING STORAGE

If it is unavoidably necessary to carry out the rust-preventive operation while the machine is indoors,
open the doors and windows to improve ventilation and prevent gas poisoning.
Operate the engine and move the machine for a short distance once a month so that a new film of oil will be
coated over movable parts and component surfaces. At the same time, also charge the battery.
For machines equipped with an air conditioner, run the air conditioner.
Rotate the tracks.

AFTER STORAGE

NOTICE
If the machine is to be used when the monthly rust prevention operation has not been carried out, please
contact your Komatsu distributor.
When using the machine after long-term storage, do as follows before using it.
Wipe off the grease from the hydraulic cylinder rods.
Add oil and grease to all places.
When a machine is stored for a long period, the moisture in the air will get into the oil. Check the oil at all parts
before and after starting the engine. If there is oil in the water, change all the oil.
