3.6 Long-term storage
3.6.1 Before storage
For keeping the machine in long-term storage (more than one
month), proceed as follows:

Clean and dry all parts and store the machine indoors. If the
machine has to be stored outdoors, park it on level ground
and cover with a tarp.

Fill the fuel tank to prevent moisture from accumulating.

Lubricate the machine and change the oil before storage.

Coat the exposed portion of the hydraulic cylinder rod with
grease.

Switch off the engine. Turn the starting switch to the OFF
position.
Only switch the battery main switch off once the green pilot
lamp on the relay box has gone out.
Remove the key to the battery main switch. Keep the battery
covered in storage.

Lock all control levers with the lock levers.

To prevent corrosion, fill the cooling system with original
Komatsu Supercoolant (AF-NAC). Check that the mixing
ratio is 30% at least.
