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 and starting switch.
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.
3.6.2 During storage
WARNING
Risk of poisoning when engine is running indoors! Open doors
and windows before starting the engine indoors.
 During storage, always operate the machine once a month so
that the oil film renews on moving parts and on the surface of
components. Also charge the battery.
 Wipe off all the grease from the hydraulic cylinder rod before
operating the work equipment.
 If the machine is equipped with an air conditioner, operate it
for 3 to 5 minutes once a month to lubricate the compressor.
Have the engine run at low idle during this operation. Check
the refrigerant level twice a year.
 If the machine is equipped with a central lubrication system,
intermediate lubrication must be carried out every month.
