16. Long-term Storage
IMPORTANT
When storing the machine, set up the machine as illus-
trated in the right figure to protect the hydraulic cylin-
der rods from being corroded.
When storing the machine for a long period, do the following:
• Clean all parts and store the machine indoors. If you
have to store the machine outdoors, park the machine on
level ground and cover it with a protective sheet.
• Apply lube oil and grease to the machine and replace the
engine oil.
• Apply a little amount of antirust to exposed parts of the
hydraulic cylinder rods.
• Fill the battery with distilled water up to the upper level
mark. After the battery has fully recharged, disconnect
the negative terminal, and cover the battery or remove
the battery from the machine to store it.
• Add an anti-freeze to the cooling water if the air temper-
ature can fall below 32°F (0°C).
Because a genuine long-life coolant (LLC) is added to
the cooling water, you need not change it until the tem-
perature falls down to -31°F (-35°C).
If the temperature falls below -31°F (-35°C), refer to Sec-
tion "25-2. Nonperiodic services" to control the density of
the cooling water.
• Lock the control levers and pedals with the lock levers
and pedal guards respectively.
• Antirust
When stored near the sea or in a place exposed to sea
breezes, the machine easily becomes rusty. Carefully ap-
ply an antirust to all exposed parts of the piston rods and
cover the machine with a polyethylene sheet or oil paper.
Some antirust solvent damages rubber materials. Be
sure to use the recommended antirust or its equivalent.
• To prevent condensation inside the fuel tank, either drain
off the fuel tank or fill the tank.
