be unscrewed through 1 or 2 revolutions.
4. Fill the jack with clear filtered oil ВМГЗС or МГЕ10А up to the level
of the filler hole.
At the ambient air temperature up to – 40° C application of transformer
oil is permissible.
Never use oils of other grades and liquids including brake fluid.
Jack failures should be eliminated timely. Seepage of oil in the plungers
and shutoff needle is eliminated by tightening the packing gland nuts. Oil leak
age through the joints of the body is corrected by tightening the body head.
Worn packing glands should be replaced.
Jack failure results from air presence in the working chamber or due to
valve sticking. To eliminate failure tap lightly on the delivery plunger handle
several times and continue the lifting. To prevent air from getting into the
working chamber of the jack, do not lift the operating plunger by hand with
the shutoff needle closed.
Incomplete lifting of the jack operating plunger occurs due to shortage of
oil. Regularly check the oil level in the jack and replenish, if required. The oil
level in the vertically positioned jack should reach the filler throat closed with

Failure in operation except for mentioned reasons may result from dirt,
which got inside the jack. To clean the jack interior of dirt, unscrew the jack
body head, pour clean kerosene into the body and pump the jack several times
with the shutoff needle open. Drain kerosene and pour fresh oil.
9.11. CAB CARE
Wash the vehicle in a shadow. Do not use soda, kerosene, gasoline as well
as seawater. If after washing with water the cab is not clean enough you may
use shampoo and other vehicle cosmetics available in the market.
Use clean sponge and soft cloth with plenty of water and do not rub too
hard.
Tar spots should be removed with castor or petrolatum oil. A mild soap
solution or pure water may easily clean the plastic parts. Never use gasoline or
solvents for the above purpose.
