Maintenance (continued)
If the Jack is not performing properly, it may have air in the hydraulic system and need
to be bled. Never attempt to bleed the Long Frame Jack while it is lifting a vehicle or
object.
Bleeding and filling the Jack with hydraulic oil
.
See the Assembly Drawing on page 8.
Filling
1.
Place the Jack on a flat, level, solid surface.
2.
If just filling the Jack, open the Cover (8.1) with a standard slot screwdriver by
removing the two Screws (8.5). Swing the Cover (8.1) open (the two Rivets (8.3) act
as hinges). Then, remove the Cover Plate (3.15) by unthreading the 4 Bolts (3.16),
and remove the Paper Washer (3.14). Note: Take care not to damage or get debris on
the Paper Washer (3.14) or Cover Plate (3.15).
3.
Using a high quality hydraulic oil, fill to the top of the Cylinder Body (3.13).
4.
Replace the Cover Plate (3.15), Paper Washer (3.14), and the Bolts (3.16). Close the
Cover (8.1) and tighten on the Screws (8.5).
Bleeding
1.
Follow Step 2 (as explained above) to fill the Cylinder Body (3.13) as if you were filling
with oil.
2.
Apply pressure on the Saddle (7.1), holding it down. Put the Handle (1.5) in the vertical
position. Turn the Screw Rod (1.4) to the left, it should fall down into place. Now, turn
the Screw Rod (1.4) right to open the release valve and hold it there. Pump the Foot
Pedal (2.1) quickly, ten times. This will bring all the air out of the system. Continue
pumping until no more air bubbles appear. Fill to the top with a high quality hydraulic
oil if necessary. Put the Screw Rod back into the normal operating position.
3.
Replace the Paper Washer (3.14), Cover Plate (3.15) and the Bolts (3.16). Close the
Cover (8.1) and tighten the Screws (8.5).
4.
Test the Floor Jack. Make sure it is functioning properly before attempting to lift a
vehicle. Move the Saddle (7.1) up and down several times to make sure it is working
properly. If not, repeat the above process.
