SAFETY INSTRUCTIONS

The floor jack is high-hazard equipment.
To avoid the risk of injuries and damage to property, read these operating instructions completely and familiarize yourself thoroughly with the product.
This jack may be used only for load lifting. Never use this jack for the raised load pulling. Pulling of the jack with lifted load is prohibited.
This jack should be used only on smooth, hard, and level surface capable of sustaining the load. Use on other surfaces may cause load to drop.
After lifting, the load should be fixed with the help of special props or supports designed to hold the rated load weight and reliably keeping it in the lifted position.
It is prohibited to stay or carry out works under the lifted load held only by the jack. Stay away from moving hinged joints of the jack.
Never exceed the maximum rated lifting capacity of the jack. Overload of the jack may result in its failure and cause personal injury.
The safety valve is adjusted for safe operation of the item with maximum rated load of 3 tons. It is prohibited to change factory settings of the safety valve on your own; it may cause failure of the item and personal injury.
It is permitted to use only the components and adapters recommended for use by the manufacturer.
It is prohibited to disassemble the jack on your own initiative, as well as make changes into the construction of the jack.
All warning labels should always be legible and these operating instructions should be kept intact during the whole service life of the jack.
Failure to heed these rules may result in causing personal injury and failure of hydraulic equipment.

BEFORE USE

Test the jack. Close the release valve by turning it with the help of the handle clockwise until it is firmly closed.
Insert the handle into the pump unit handle sleeve and make sure that it is reliably fixed in the slot. Pump handle several times up and down; when this is done, the lifting arm of the jack should start rising. To lower the lifting arm, turn the release valve with the help of the handle counterclockwise by no more than three turns, and when the lifting arm is lowered completely, close the release valve by turning its handle clockwise as far as it goes.

CAUTION!
Operation of the jack in the wrong position, on the side, in the upside down position is not allowed.

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:

The lift point in the vehicle body is positioned exactly against the center of the saddle;
The vehicle may not slip off the jack;
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:

The lift point in the vehicle body is positioned exactly against the center of the saddle;
The vehicle may not slip off the jack;
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.

MAINTENANCE

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. Provision is made to lubricate the axle of the lifting arm through a special lubrication nipple.
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. 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.
3. Return the oil filler plug back home.
4. 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.
5. 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 abovementioned procedure one more time.
Jack will not lower fully| The return spring of the
lifting arm has slipped off or is broken| Drive it home or replace.
Lubricate all moving parts of the lifting arm.
Oil level is too high| Check oil level and drain excess by opening the oil filler plug.
