Bleeding and filling the Jack with hydraulic oil.
1. Place the Lift on a flat, level, solid surface.
2. If just filling the Jack, open the Oil Filler Plug (10a) and check the oil. Fill to the top of the
Oil Reservoir (9a) with a high quality hydraulic oil if necessary.
3. If bleeding, with the Oil Filler Plug (10a) removed, use one foot to step on and keep the
Release Pedal (26) down, while you quickly pump the Foot Pedal (24) ten times. This will
bring all the air out of the system. Continue pumping until no more air bubbles appear. Fill to the
top of the Oil Reservoir (9a) with a high quality hydraulic oil if necessary. Repeat if necessary.
4. Replace the Oil Filler Plug (10a) .
5. Test the Jack. Make sure it is functioning properly before attempting to lift another load.
Pump the Foot Pedal (24) up and down several times, and test the Release Pedal (26) to
make sure it is working properly; if not, repeat the above process. If the lift continues to func-
tion improperly, have a qualified service technician check the product.
