Long-Term Storage
This section describes only the long-term storage
methods that are not defined in standard
specifications.
Use the following procedure for storing the
machine for 6 months or longer (3 months or
longer if stored in hot or humid environment).
Before Storage
Place the machine in the travelling position during
long-term storage to protect the cylinder rods.
(Cylinder rod corrosion prevention) See
“TRAVELLING POSITION” on page 4-29.
Fig. 5-119
When storing the machine for long periods, follow
these procedures:
• Wash and clean each section of the machine
and store inside. If the machine is to be stored
outside, select a flat location where the machine
will not be exposed to water, flooding or other
elements.
• Grease the machine and replace the oil.
The recommended storage conditions are as
follows in order to extend the battery life:
• Avoid storing with the battery charged above
95% or below 10%.
• Store at an ambient temperature not exceeding
35°C.
• Store away from direct sunlight.
• Store where condensation will not occur.
• Disconnect the battery.
During Storage
Operate the machine once a month during
storage to maintain an oil film on lubricated parts
and to prevent corrosion.
Charge to a battery level of approximately 50%
once every three months to avoid completely
discharging the battery.
After Storage
NOTICE: If you did not operate the machine to
prevent corrosion once a month or did not charge
the battery once every three months during
long-term storage, contact us or our sales service
agency before using the machine.
Perform the following procedures before using the
machine after long periods of storage.
• Grease the machine and replace the oil.
• Remove the drain plug on the hydraulic oil tank,
then drain the contaminating water.
• Charge the battery.
• Perform all specified pre-start checks before
starting and operating.
