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 Pad (#43) is at one of the recommended lifting points.
Turn the Upper Handle (#23) clockwise to lock the release valve. Pump the Upper Handle
(#23) until the Saddle Pad (#43) fully engages the lifting point, then continue to pump the
Jack above the jack stands.
3. Remove the jack stands.
4. Slowly turn the Upper Handle (#23) 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.

Bleeding And Refilling
To Bleed/Purge excessive air from system:
1. Place Jack on flat, level and solid surface.
2. Turn the Breathing Screw (14A) fully counterclockwise. (See Figure 1, below)
3. Turn the Handle (20) to a position where the Discharge Valve is closed enough for the
Saddle (41) to rise when you pump with no pressure on the Saddle, but open enough so
that the Saddle does not rise when you pump with one hand while applying pressure to the
Saddle with your other hand. (If the Saddle is up, turn the Handle slowly counterclockwise
until the Saddle begins to go down slowly. If the Saddle is down, while pumping quickly, turn
the Handle slowly clockwise until the Saddle begins to rise.)
4. While holding down the Saddle with one hand, rapidly pump the Handle with the other
hand, so that air comes out from between the Breathing Screw and the Oil Plug (13A). Con-
tinue pumping until air stops coming out and you see oil appearing between the Breathing
Screw and the Oil Plug.
5. Tighten the Breathing Screw by turning it clockwise as far as it will go. Then turn it 360°
counterclockwise.
To Refill Hydraulic fluid (if unable to bleed/purge or Saddle stops part way):
1. Use wrench (not included) to unscrew Oil Plug.
2. Pour high-quality hydraulic oil into hole and replace Oil Plug. Tighten with wrench.
3. Follow the Bleed/Purge Instructions above.
