15. LONG-TERM STORAGE
15.1 BEFORE STORAGE
When putting the machine in storage for a long time, do as
follows.
‡
After every part is washed and dried, house the machine in a dry
building. Never leave it outdoors.
If the machine must be left outdoors, park it on well-drained
concrete and cover it with canvas, etc.
‡ Completely fill the fuel tank, lubricate, and change the oil before
storage.
‡ Apply a thin coat of grease to the metal surface of the hydraulic
piston rods.
‡ Disconnect the negative terminals of the battery and cover it, or
remove it from the machine and store it separately.
‡ If the ambient temperature is expected to drop below 0°C,
always add antifreeze to the cooling water.
‡ Apply the safety locks to the work equipment control lever and
directional lever, then apply the parking brake.
15.2 DURING STORAGE

WARNING
If it is unavoidably necessary to carry out the rust-prevention
operation while the machine is indoors, open the doors and
windows to improve ventilation and prevent gas poisoning.
Operate the engine and move the machine for a short distance
once a month so that a new film of oil will be coated over movable
parts and component surfaces. At the same time, also charge the
battery.
Before operating the work equipment, wipe off the grease on the
hydraulic piston rod.
15.3 AFTER STORAGE
NOTICE
If the machine is stored without carrying out the monthly rust
prevention operation, request your Komatsu distributor for service.
Carry out the following procedure when taking the machine out
of long-term storage.
‡ Wipe off the grease from the hydraulic cylinder rods.
‡ Add oil and grease to all places.
