Storage of the machine
1. Preparation for the storage
To store the machine for a long time, do as follows:
1) Clean and flush all components before placing the machine indoors. If the machine has to
be stored outdoors, choose a flat ground and cover it with canvas.
2) Apply a thin layer of lubricating grease to the metal surface of the piston rod. Lubricate all
the lubricating points.
3) Remove the battery, charge it, and store it in a dry and non-freezing place.
4) Drain the engine oil when it is still hot and fill with corrosion-resistant oil. The
corrosion-resistant oil used for piston engines is MIL-L-21260 type. For storage in winter,
Grade 1 or 2 SAE10W should be used; for storage in summer, Grade SAE30 should be
used.
5) Add 4-6% of the same type of corrosion-resistant oil to the fuel and mix the two well. To
prevent condensation, the fuel tank needs to be refilled with this mixed fuel.
6) Check the antifreeze performance of the coolant and add antifreeze to ensure its
antifreeze strength is at least -20
℃
. Coolant not containing anti-corrosion agents due to
climate reasons should be added with the agents (such as 5% anti-corrosion agent
according to MIL-G4339C).
7) Start the engine and let it run for more than 15 minutes, with different speeds but without
load. When draining the lubricating oil of hydraulic components and reducers, it should also
be allowed to run and drain, and then replaced with new oil for storage.
8) Close the inlet of the air filter and the outlet of the exhaust pipe. For this, it is
recommended to use thick plastic paper and adhesive tape.
9) Lock the platform, raise the safety lock handle (raise the left control box), so that the
control levers and pedals are in a locked state.
10) Place the shut-off valve for installing accessories on the machine in the locked position.
Install a screw plug on the elbow.
11) Keep the machine clean and store it in a dry place.
Attention: When storing the machine,
adjust it to the position shown in the
right figure to protect the cylinder
piston rod and prevent rust on the
piston rod.
