Low Profile Floor Jack 

        

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.  

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 serious injury and/or property damage.

6.  Center saddle of the jack stand(s) under the vehicle’s 

lifting point(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.
