OPERATION

LONG-TERM STORAGE

BEFORE STORAGE

When putting the machine in storage for a long time (more than 1 month), do as follows.
Clean and wash all parts, then store the machine indoors. If the machine has to be stored outdoors, select level
ground and cover the machine with canvas.
Completely fill the fuel tank. This prevents moisture from collecting.
Lubricate and change the oil before storage.
Coat the exposed portion of the hydraulic cylinder piston rod with grease.
Disconnect the negative terminals of the battery and cover it, or remove it from the machine and store it
separately.
Place all control levers at NEUTRAL position, set the work equipment lock lever and parking brake lever to LOCK
position, and set the fuel control dial to Low idle (MIN) position.
To prevent rust, fill with coolant to give a density of at least 30% for the engine coolant.

DURING STORAGE

If it is necessary to perform the rust-prevention operation while the machine is indoors, open the doors and windows to improve
ventilation and prevent gas poisoning.
During storage, operate and move the machine for a short distance once a month so that a new film of oil will coat
moving parts. At the same time, also charge the battery.
When operating the work equipment, wipe off all the grease from the hydraulic cylinder rods.
If the machine is equipped with an air conditioner, operate the air conditioner for 3 to 5 minutes once a month to
lubricate all parts of the air conditioner compressor. Always run the engine at Low idle (MIN) when doing this.
In addition, check the refrigerant level twice a year.

AFTER STORAGE

NOTICE
If the machine has been stored without performing the monthly rust-prevention operation, consult your Komatsu distributor
before using it.
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 at all lubrication points.
When the machine is stored for a long period, moisture in the air will mix with the oil. Check the oil before and after
starting the engine. If there is water in the oil, change all the oil.

STARTING MACHINE AFTER LONG-TERM STORAGE

When starting the engine after the machine has been in storage for a long period, carry out the warming-up operation
thoroughly. For details, see the procedure in "WARMING UP OPERATIONS (PAGE 3-122)".
