PRECAUTIONS FOR LONG-TERM STORAGE
PREPARATION FOR LONG-TERM STORAGE
NOTICE
When storing the machine (more than 1 month), set the
machine in the posture shown in the figure to protect the
piston rod of hydraulic cylinder.
(To prevent the cylinder piston rods from rusting)
When putting the machine in storage for a long time (more than 1 month), do as follows.
• Clean and wash all the parts of the machine and store the machine indoors. If the machine has to be stored
outdoors, select a level ground and cover it with waterproof sheet.
• Fill up the fuel tank. This prevents dew condensation.
• Grease the machine and change the oil before storage.
• Coat the exposed portion of the hydraulic cylinder piston rod with grease.
• After turning the starting switch to OFF position, check that the system operating lamp is not lit. Then set
the battery disconnect switch to OFF position and remove the key. When storing the battery, cover it.
• To prevent rust, fill the cooling circuit with Non-Amine Engine Coolant (AF-NAC) to give a density of 30 % or
more for the engine coolant.
MAINTENANCE DURING LONG-TERM 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, charge the battery as well.
• 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 when doing
this. In addition, check the refrigerant level twice a year.
STARTING MACHINE AFTER LONG-TERM STORAGE
NOTICE
If the machine has been stored without performing the monthly rust-prevention operation, consult your
Komatsu distributor before using it.
Perform the following items when using the machine after long-term storage.
• Wipe off the grease from the hydraulic cylinder piston 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.
• Insert the battery disconnect switch key and turn it to ON position.
• If the machine is stored for a long period with the battery disconnect switch at OFF position or the battery
terminal disconnected, the time information of the clock and radio tuning information may be lost. In this
case, set them again by referring to “CLOCK ADJUSTMENT” and “HANDLE RADIO”.
