JACK OPERATING PROCEDURE 

(THROUGH THE EXAMPLE OF VEHICLE LIFTING)

Make sure that the vehicle and jack are on smooth and hard surface and the jack has a possibility to be displaced 
during lifting and lowering of the vehicle. Uneven, soft or slanted surfaces create hazard for the execution of works.
Apply the parking brake in the vehicle, turn the automatic gearbox selector into the Р position or engage the first 
gear in the vehicles with the mechanical gearbox; place vehicle wheels for straight-driving direction. Additionally, 
fix the wheels which are not planned to be raised from the ground with wedge chocks. Make sure that the vehicle 
passenger compartment is free of passengers.
With the help of the vehicle instruction manual, determine the points in the car body that may be used for car 
lifting by the jack. Install the jack with fully lowered lifting arm under the vehicle opposite the vehicle lifting point 
designed to contact jacks.
Close the release valve with the help of the jack handle by turning it clockwise as far as it goes, then insert  
the handle into the pump unit handle sleeve and slowly pump until the lifting arm of the jack touches the lifting 
point in the vehicle designed to contact jacks.
Check position of the lifting arm saddle of the jack. Make sure that:
1.  The lift point in the vehicle body is positioned exactly against the center of the saddle; 
2.  The vehicle may not slip off the jack;
3.  The lifting arm of the jack will not damage any parts and components of the vehicle.
Lift the vehicle to the required height by pumping the handle of the jack. Install special stands or props under  
the body of the vehicle.
Slowly turn the release valve by rotating the handle counterclockwise until the vehicle starts lowering  
on the props. Make sure that the props are reliably holding the elevated vehicle.
Prior to lowering the vehicle after finishing the operations, make sure that there are no people or foreign objects 
under the vehicle.
Screw the handle of the jack by rotating it clockwise as far as it goes, then slowly pump it until the lifting arm  
of the jack touches the vehicle lifting point designed to contact jacks.
Check position of the lifting arm saddle of the jack. Make sure that:
1.  The lift point in the vehicle body is positioned exactly against the center of the saddle; 
2.  The vehicle may not slip off the jack;
3.  The lifting arm of the jack will not damage any parts and components of the vehicle.
Raise the vehicle a little by pumping the handle of the jack so as to remove the supports from under it. Remove  
the supports to the side so that they permit the vehicle to rest on its wheels.
Slowly turn the handle of the jack counterclockwise until the vehicle starts lowering. Take care that the vehicle  
is lowering slowly and smoothly.

CAUTION!

Sharp lowering may cause slipping of the vehicle from the jack resulting  

in personal injury of the operator.

After the vehicle is fully lowered on its wheels and is stable, wait until the lifting arm of the jack goes  
off from the lift point of the vehicle. Then roll the jack aside and close the release valve by rotating the handle  
of the jack clockwise until it is fully closed.
