MAINTENANCE DURING LONG-TERM STORAGE
k k
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 piston rods of the hydraulic cylinder.
• Add oil and grease at all lubrication points.
• After long-term storage, the moisture in the atmosphere has mixed in the oil, so check the oil in each part
before/after starting the engine.
If there is water in the oil, change all the oil.
• Connect the negative (-) terminal after installing the battery or removing the cover.
For machines equipped with a battery disconnect switch (optional), insert the key into the battery discon-
nect switch (optional) and turn the key to ON position.
• If the machine is stored for a long period with the battery disconnect switch (if equipped) OFF or the battery
terminal disconnected, the time information of the clock and radio (if equipped) tuning information may be
lost.
In that case, set them again by referring to “CLOCK ADJUSTMENT” and “HANDLE RADIO”.
• When starting the engine, perform the engine warm-up operation thoroughly.
