When the jack is not used, the lifting arm of the jack should be fully lowered. This will prevent rusting of
the lifting arm piston rod.
Periodically lubricate moving parts of the jack: lifting arm piston rod, pump rods, axles and bearings
of the wheels. Use any engine oil for the purpose.
Do not use gasoline, kerosene, solvents and abrasive substances for cleaning the jack. They may damage
rubber seals and cause oil leakage.
Store jack on level surface in a clean and dry place. When doing so, see that the lifting arm of the jack is fully
lowered, and the release valve is fully closed.
The repair of the item should be performed only by highly qualified specialists of the servicing center. The list
of service centers is presented in the warranty card .
TROUBLEShOOTING chART
Symptom
Possible cause
Corrective action
Jack will not lift or
lower load
Insufficient oil level
Check oil level as per the following instructions:
1. Turn the release valve counterclockwise so that the piston
goes down fully. If the lifting arm does not go down, use
force.
2. Lift the organizer handle.
3. Place jack in a vertical position, open oil filler plug. Oil level
should be at the level of the lower point of the filler hole.
If the oil level is lower, top up oil to the required level. Use
only recommended type of oil.
4. Return the oil filler plug back home.
5. Close the release valve and lift fully and lower the lifting
arm of the jack several times. This will help fully distribute oil
in the whole system. In most cases, this helps to restore
the serviceability of the item.
6. Check operation of the jack.
Air is trapped in the
system of the jack
1. Turn the release valve counterclockwise by one full turn.
2. Insert the handle into the pump unit handle sleeve and
work six full strokes.
3. Turn the release valve clockwise as far as it goes
so as to close it fully.
4. Continue to pump the pump with the handle until the
lifting arm occupies the upper position and pump handle
several more strokes so as to blow all the air from the piston.
5. Carefully open oil filler plug partially so as to release
the trapped air.
6. Turn the release valve counterclockwise by one full turn;
lower the lifting arm to the extreme low position. Use force,
if necessary.
7. Close the release valve clockwise as far as it goes and check
serviceability of the jack. If necessary, repeat the above-
mentioned procedure one more time.
