3.6 Long-term storage
3.6.1

Before storage

When keeping in long-term storage (more than one month),
store as follows.
Clean and wash all parts, then store the machine indoors. If
the machine has to be stored outdoors, select level ground
and cover the machine with a sheet.
Fill the fuel tank to prevent moisture from accumulating.
Lubricate and change the oil before storage.
Coat the exposed portion of the hydraulic cylinder piston rod
with grease.
Disconnect the negative terminals of the battery and cover it
or remove it from the machine and store it separately.
Lock each control lever with the lock lever.
To prevent corrosion, be sure to fill the cooling system with
Supercoolant (AF-NAC) or permanent type antifreeze (den-
sity between 30% and 68%).
3.6.2

During storage

WARNING
If it is unavoidably necessary to carry out the rust-preventive
operation while the machine is indoors, open the doors and win-
dows to improve ventilation and prevent gas poisoning.
During storage, always operate the machine 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.
When operating the work equipment, wipe off all the grease
from the hydraulic cylinder rod.
If the machine is equipped with an air conditioner, operate it
for 3 to 5 minutes once a month to lubricate each portion of
its compressor. Be sure to idle the engine at low speed for
this purpose. Also, check the quantity of refrigerant twice a
year.
