Operation (continued)
Lowering Vehicles.
1. First, clear any tools or equipment from under the vehicle. Make sure there are no
obstructions.
2. Position the Jack so that the Saddle (#2-1) is at one of the recommended lifting points.
Turn the Lower Handle (#11-7) clockwise to lock the release valve. Pump the Lower
Handle (#11-7) until the Saddle (#2-1) fully engages the lifting point, then continue to pump
the Jack above the jack stands.
3. Remove the jack stands.
4. Slowly turn the Lower Handle (#11-7) counterclockwise to open the release valve, and
gently to lower the vehicle.
5. Pull the Jack clear of the vehicle and store in a safe place.
If the Jack is not performing properly, it may have air in the hydraulic system and need
to be bled.
Bleeding and filling the Jack with hydraulic oil.
1. Place the Jack on a flat, level, solid surface.
2. If just filling the Jack, open the Oil Plug (#6-2) and check the oil. Fill to the top with a high
quality hydraulic oil if necessary.
3. If bleeding, with the Oil Plug (#6-2) removed, fully open the release valve by turning the
Lower Handle (#11-7) counter-clockwise.
4. Apply pressure on the Saddle (#2-1), holding it down. Quickly crank the Lower
Handle (#11-7) ten times. This will bring all the air out of the system. Continue cranking
until no more air bubbles appear. Fill to the top with a high quality hydraulic oil if necessary.
Repeat if necessary.
5. Replace the Oil Plug (#6-2).
6. Test the Floor Jack. Make sure it is functioning properly before attempting to lift another
vehicle. Crank the Saddle (#2-1) up and down several times to make sure it is working prop-
erly. If not, repeat the above process.
1. Keep the Jack clean and dry.
2. Periodically lubricate the caster wheels with high quality grease.
3. Periodically dismantle and lubricate the handle assembly and all lift arm linkages.
4. Watch for hydraulic oil leaks. Fill oil if necessary. If leaks persist, contact an
authorized service technician.
5. If the Jack does not lift to satisfaction, take it to an authorized service technician.
