LONG-TERM STORAGE
BEFORE STORAGE
When keeping in long-term storage (more than one month), store 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 a sheet.
Completely fill the fuel tank. This prevents moisture from collecting.
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 separately.
Place all control levers in the neutral position, set the work equipment lock lever and parking brake lever in the
LOCK position, and set the fuel control dial to the low idling position.
To prevent rust, fill with Komatsu genuine supercoolant (AF-NAC) to give a density of at least 30% for the engine
coolant.
DURING STORAGE
WARNING
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.
Before operating the work equipment, wipe the grease off the hydraulic piston rod.
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 when doing this. In addition,
check the refrigerant level twice a year.
AFTER STORAGE
NOTICE
If the machine has been stored without carrying out 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.
