Long time storage
1. Before storage
When putting the machine in storage for a long time, do as follow:
1) After every part is washed and dried, the machine shall be housed
in a dry building. Never leave it outdoor. In case it is indispensable
to leave it outdoors, park the machine on a flat road and cover it
with canvas etc.
2) Apply a thin coat of grease to metal surface of the hydraulic piston
rods.
3) Removing the battery, which will be fulfilled with the electrolyte and
electricity and then put it at a not dry ice-free areas.
4) Drain the engine oil at the warm state, and change with
anticorrosion oil. For the piston-type engine the anticorrosion oil
MIL-L-21260 is selected. For a winter storage use 1.grade or
2.grade SAE 10W, but for a summer storage use SAE 30.
5) Fill also the same type of the anticorrosion oil for about 4%~6% in
the fuel oil, and mix them completely. In order to prevent from
bringing about condensed water, refill the fuel tank with this kind of
mixed oil.
6) Check the antifreeze function of the coolant. By filling with
antifreeze, its antifreeze ability is at least 20°. There is non
corrosion inhibitor in coolant because of the climate, you should fill
with corrosion inhibitor.(it contains 5% corrosion inhibitor
according to MIL-G4339C.)
7) Start the engine, run it above 15mins at different rotational speed
and without load.
8) Shut off the inlet of the air filter and the outlet of the exhaust pipe.
Plastic thick papers and tape are recommended in this case.
9) Lock the platform, and set the safety lock lever in lock position
（

, set all levers in lock position.
10) Keep the machine clean, and place it in a dry space.
11) Lock the cut-off valve which for install the attachment, and installing a
bolt in the elbow.
Attention: When the machine
is not being used, set the work
equipment as showed in
beside figure. This will
