1) to operate the Release Valve.

3.  Turn the Handle (Fig. 1) counterclockwise to open valve.
4.  Pump the Handle (Fig. 1) up and down quickly for several 

times to purge the air from the system.

5.  Tighten the Fill Screw (Fig. 2).

Adding Oil

1.  Remove the Fill Screw (Fig. 2). 
2.  Add qualified hydraulic oil of high grade into the Fill 

Screw (Fig. 2) slowly until the oil reaches the top of the

Lifting

1.  Park vehicle on a flat, level, solid, surface safely 

away from oncoming traffic.  Turn off the vehicle’s 

engine.  Place the vehicle’s transmission in “PARK” 

(if automatic) or in its lowest gear (if manual).  Set the 

vehicle’s emergency brake.  Then, chock the wheels 

that are not being lifted.

2.  Turn the Handle counterclockwise to lower the Jack.  

Once the Jack is fully lowered, turn the Handle firmly 

clockwise to close it.

3.  Carefully position the Saddle of the Jack (Fig. 1) 

under the vehicle manufacturer’s recommended lifting 

point.(See vehicle manufacturer’s owner’s manual 

for location of frame lifting point when lifting only one 

wheel and frame lifting points when lifting the entire 

front or rear end of the vehicle.)

4.  Pump the Handle until the top of the Jack’s Saddle has 

nearly reached the vehicle lifting point.

Note: 

The Jack should be positioned at 90° to the vehicle’s 

lifting point to ensure the Jack’s Saddle and vehicle lifting 

point are in alignment.  If not, reposition the Jack before 

lifting the vehicle.
5.  To lift the vehicle, pump the Handle of the Jack. Use 

smooth, full strokes for best results.

6.  Once the vehicle is raised, slide a jack stand of 

appropriate capacity (not included) under the proper 

lifting point referred to in the vehicle owner’s manual.  

Always use two jack stands, position them at the same 

point on each side of the vehicle.

The rated capacity of jack stands is per pair, not the  

individual capacities combined unless specifically noted on 

the product by the jack stand manufacturer. Do not exceed 

rated jack stand capacity. Ensure that the vehicle support 

points are fully captured between the outer lugs of both jack 

stands. Use a matched pair of jack stands per vehicle to 

support one end only. Use 1 pair per vehicle only. Failure to 

do so may result in sudden loss of load, which may cause 

personal injury and/or property damage.
