BEFORE STORAGE 3
NOTICE
To protect the hydraulic cylinder piston rod while in stor-
age, keep the work equipment in the posture shown at
right.
(This prevents rust from developing on the piston rod)
When putting the machine in storage for a long time (more than one month), do as follows.
q
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 canvas.
q
Completely fill the fuel tank. This prevents moisture from collecting.
q
Lubricate and change the oil before storage.
q
Coat the exposed portion of the hydraulic cylinder piston rod with grease.
q
Disconnect the negative terminals of the battery and cover it or remove it from the machine and store it sepa-
rately.
q
Lock each control lever and pedal with the lock lever and pedal lock.
q
Set the stop valve to the LOCK position on machines ready for attachments. Install the blind plugs to the
elbows.
For details of the LOCK and FREE positions of the stop valve, see “ATTACHMENT REMOVAL AND INSTAL-
LATION (6-17)“.
q
To prevent corrosion, be sure to fill the cooling system with Supercoolant (AF-NAC) or permanent type anti-
freeze (density between 30% and 68%).
q
If the ambient temperature is expected to drop below 0
o
C, change fuel and oil to low viscosity type for all com-
ponents. For detail seeRECOMMENDED FUEL, COOLANT, AND LUBRICANT (4-12)
DURING STORAGE 3
WARNING
If it is necessary to perform the rust-prevention operation while the machine is indoors, open the doors
and windows to improve ventilation and prevent gas poisoning.
q
During storage, operate and move the machine for a short distance once a month so that a new film of oil will
coat moving parts. At the same time, also charge the battery.
q
When operating the work equipment, wipe off all the grease from the hydraulic cylinder rods.
q
If the machine is equipped with an air conditioner, operate the air conditioner for 3 to 5 minutes once a month
to lubricate all parts of the air conditioner compressor. Always run the engine at low idle when doing this. In
addition, check the refrigerant level twice a year.
