PRECAUTIONS FOR LONG-TERM STORAGE
PREPARATION FOR LONG-TERM STORAGE
NOTICE
When storing the machine (1 month or more), set the ma-
chine in the posture shown in the figure to protect the cyl-
inder rods.
(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 parts of the machine and store it indoors. If the machine has to be stored outdoors,
select a level ground and cover the machine with waterproof sheet.
• Fill up the fuel tank. This prevents dew condensation.
• Fill up DEF tank (Except cold weather condition). If the inside dries up, urea is deposited and it may cause
failures in component operation.
• Grease the machine and change the oil before storage.
• Coat the exposed portion of the hydraulic cylinder piston rod with grease.
• Turn the starting switch to OFF position and turn the battery disconnect switch key to OFF position, and
remove it. When storing the battery, cover it.
For the operation of the battery disconnect switch, see “BATTERY DISCONNECT SWITCH (3-113)”.
• Set the attachment control pedal to the lock position on the machines ready for attachments.
• If the machine is ready for installation of attachment, set the stop valve to the LOCK position. Install the
blind plugs to the elbows.
For explanation of LOCK and FREE states of the stop valve, see “METHOD FOR REMOVING AND IN-
STALLING ATTACHMENT (6-21)”.
• To prevent rust, fill the cooling circuit with Non-Amine Engine Coolant (AF-NAC) to give a density of at least
30% 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.
When using the machine after long-term storage, perform the following items before using it.
