2. During storage
1) During storage, operate the machine once a month so that a new oil film is attached to the surface of the moving parts.
At the same time, the battery must be charged.
2) For machines equipped with air-conditioning, the air-conditioning must be operated.
3) Rotate the track.
Warning: When the machine is indoors, if it is necessary to perform anti-rust operations,
open doors and windows to promote air circulation to prevent gas poisoning.
3. Return to use after storage
When using the machine after long-term storage, follow the below steps before using it.
1) Wipe off the grease coated on the surface of the piston rod of the cylinder.
2) Fill all parts with engine oil and grease.
3) When the machine is stored for a long time, the moisture in the atmosphere will enter the oil. Before or after starting the
engine, check the oil in all parts. If there is water in the oil, replace all the oil.
Note: 1)
Under normal climatic conditions, the storage method described above can store the
excavator for one year. However, after
6 months of storage, the parts should be rotated for 15
minutes without loading. At the same time, add lubricating oil to each part.
2)
Before the excavator that has been stored for a long time is put into use again, the necessary work
and various inspections should be done. After the excavator has been stored for one year, the oil in
the reducer and hydraulic circuit must be drained and renewed.
