LONG TERM STORAGE
BEFORE STORAGE
NOTICE
To protect the hydraulic cylinder piston rod while in storage, 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.
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.
Completely fill the fuel tank. This prevents moisture from collecting.
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 and pedal with the lock lever and pedal lock.
Set the stop valve to the LOCK position on machines ready for attachments. Install the blind plugs to the elbows.
Set the selector valve on the machines which can install attachments to the "Where no attachment is mounted"
position.
To prevent rust, fill with COOLANT to give a density of at least 30% for the engine coolant.
DURING STORAGE
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.
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.
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.
AFTER STORAGE
NOTICE
If the machine has been stored without carrying out the monthly rust-prevention operation, consult your Komatsu distributor
before using it.
When using the machine after long-term storage, do as follows before using it.
Wipe off the grease from the hydraulic cylinder rods.
Add oil and grease at all lubrication points.
When the machine is stored for a long period, moisture in the air will mix with the oil. Check the oil before and after
starting the engine. If there is water in the oil, change all the oil.
