If the machine is to be stored for more than one month, observe the following precautions so that its function will not be
impaired during storage.
Contents of Work
Wash Machine Sufficiently wash the machine to remove stuck mud and/or dust.
Supply Oil and Grease Check for low level/contamination of lubricating oil. Ref. II or change as necessary.
Supply grease to greased parts. Apply a thin coat of oil to parts susceptible to rust
(i.e. cylinder rods etc.)

Prevention of Dust and Moisture Store the machine in a relatively dry garage and cover it.
Tools Inspect and repair, then store.
Lubrication Operation
No-load Operation at a Slow Speed
for Several Minutes
If the oil films of the parts are broken and parts are rusted, they will be worn abnor

mally when operated the next time. To prevent this, operate the machine at least
once a month to lubricate the parts. At this time, check the coolant and lubrication
oil levels.
In case the batteries are kept disconnected for more than
one month or when the batteries are reconnected, contact
your nearest Hitachi dealer.
NOTE Lubrication operation means that a series of operations
such as drive, and loader front operation are repeated
a few times after performing the warm-up operation.
Before operating the loader front attachment and
steering wheel, remove rust-prevention oil coated on
the hydraulic cylinder rods.
