Operation

  Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this 

manual including all text under subheadings therein before set up or use of this product.

Lifting

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.

1.  Turn the Handle counterclockwise to lower the Jack.   

Once the Jack is fully lowered, turn the 
Handle firmly clockwise to close it.

2.  Carefully position the Saddle of the Jack under the 

vehicle manufacturer’s recommended lifting point. 
(See vehicle manufacturer’s owner’s manual 
for location of frame lifting point.)

3.  Pump the Handle until the top of the Jack’s Saddle 

has nearly reached the vehicle lifting point. Position 
the Saddle directly under the vehicle’s lifting point.

4.  To lift the vehicle, pump the Handle of 

the Jack. Use smooth, full strokes.

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

appropriate capacity (not included) under a 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.

WARNING!

 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 seated 
in the saddle of both jack stands. Use a matched pair 
of jack stands per vehicle to support one end only. 
Failure to do so may result in the load suddenly falling, 
which may cause personal injury and/or property damage.

6.  Center the vehicle’s lifting point(s) on the saddle of 

the jack stand(s).  Set the jack stand(s) to the same 
height according to the manufacturer’s instructions, 
making sure that they lock securely into position.

7.  Slowly turn the Handle counterclockwise to lower 

the vehicle onto the saddle(s) of the jack stand(s). 
Then, turn the Handle firmly clockwise to close it.

Lowering

1.  Carefully remove all tools, parts, etc. 

from under the vehicle.

2.  Position the Saddle under the lifting point. 

Turn the Handle firmly clockwise and raise 
load high enough to clear the jack stands, 
then carefully remove jack stands.

3.  Slowly turn the Handle counterclockwise 

(never more than 1/2 full turn) to lower 
the vehicle onto the ground.

4.  Lower the Jack completely.  Then, store in a 

safe, dry location out of reach of children.

5.  To prevent accidents, turn off the tool and 

disconnect its power supply after use.  Clean, then 
store the tool indoors out of children’s reach.
