Bleeding
BEFORE EACH USE OR IF JACK PERFORMANCE DECREASES, check for excessive air and proper hydraulic fluid level in Jack. If Jack appears not to be working properly, it may be necessary to purge its hydraulic system of excessive air as follows:
- Turn handle counter clockwise to open Release Valve.
- Remove four screws holding on pump cover.
- Remove Oil Fill Plug and top off hydraulic oil.
- Apply pressure to saddle and quickly pump handle several times.
- Check Oil Fill Hole again and top off with hydraulic oil if necessary.
- Replace the Oil Fill Plug and turn handle clockwise to close Release Valve.
- Test several times for proper operation before attempting to lift a load.
Adding Hydraulic Fluid
- Remove Cover Plate and Fill Plug.
- Add high grade hydraulic fluid (sold separately) slowly until the fluid reaches 1/4 below the top of the Fill Port.
Note: Do not touch the Handle when adding hydraulic fluid. - Assemble Fill Plug, close Cover Plate, and reinstall the screws.
Lifting
WARNING
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.
- Slowly twist the Handle counter clockwise to lower the Jack. Once the Jack is fully lowered, twist the Handle firmly clockwise.
- Carefully position the Jack’s Saddle under the vehicle manufacturer’s recommended lifting point. (See vehicle manufacturer’s owner’s manual for location of frame lifting point.)
- Pump the Handle until the top of the Saddle has nearly reached the vehicle’s lifting point. Position the Saddle directly under the vehicle’s lifting point.
- To lift the vehicle, pump the Handle. Use smooth, full strokes.
- Select matching jack stands (sold separately) of appropriate capacity. Set the jack stands to the same height according to the manufacturer’s instructions, making sure they lock securely into position.
- Position the jack stands’ saddles under the vehicle manufacturer’s recommended support points.
Ensure that the vehicle support points are fully seated in the saddles of both jack stands. Use a matched pair of jack stands per vehicle to support one end only. - Slowly twist the Handle counter clockwise to lower the vehicle onto the jack stands’ saddles.
- Once the vehicle is fully seated on the jack stands, continue slowly lowering the Jack until it is completely lowered.
- Remove the Jack and store safely out of the way.
Lowering
- Carefully remove all tools, parts, etc. from under the vehicle.
- Position the Jack’s Saddle under the lifting point. Turn the Release Knob firmly clockwise and raise vehicle high enough to clear the jack stands.
- Carefully remove the jack stands.
- Slowly turn the Release Knob counter clockwise to lower the vehicle onto the ground.
- Lower the Jack completely. Store the Jack indoors out of children’s reach.

Procedures not specifically explained in this manual must be performed only by a qualified technician.
WARNING
TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use.
Cleaning, Maintenance, and Lubrication
- BEFORE EACH USE, inspect the general condition of the Jack. Check for:
• loose hardware,
• misalignment or binding of moving parts,
• cracked or broken parts,
• any condition that may affect its safe operation. - BEFORE EACH USE, thoroughly test the Jack for proper operation prior to its actual use. If the Jack appears not to be working properly, follow Bleeding instructions on page 4.

- AT LEAST ONCE EVERY THREE YEARS, change the hydraulic fluid:
a. With the Jack fully lowered, remove the Cover Plate and Fill Plug.
b. Tip the Jack over to allow the old hydraulic fluid to drain out completely. Dispose of the old hydraulic fluid in accordance with local regulations.
c. With the Jack upright, completely fill the Hydraulic Unit with high grade hydraulic fluid until the fluid is 1/4 below the top of the Fill Port.
d. Turn the Release Knob counter clockwise to open the Release Valve.
e. Pump the Handle or Foot Pedal up and down quickly several times to purge air from the system.
