OPERATION

PRECAUTIONS FOR LONG-TERM STORAGE

PREPARATION FOR LONG-TERM STORAGE

NOTICE
• When storing the machine (1 month or more), set the
machine in the posture shown in the figure to protect
the cylinder rods. (To prevent the cylinder piston rods
from rusting)
• The ambient temperature range during periods of inac-
tivity should be between -20 and +45 °C.
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, etc.
• 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.
• 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 (3-121)".
• Lock each control lever and pedal with the lock lever and lock cover.
• If the machine is ready for installation of attachment, set the selector valve to the "General attachments
such as crusher" position.
• 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

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.
• 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.
