OWNER'S MANUAL
SETUP
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. Remove the bolt from under the handle yoke. Insert the handle tube in the handle yoke while simultaneously inserting the locking rod in
the handle yoke guide holes.
2. Raise the lock lever on the handle assembly up so the locking rod does not have to come in contact with the handle yoke bracket. Rotate
the release knob at the top of the handle back and forth until you feel the bottom of the handle engage the release valve fitting inside and
at the bottom of the handle yoke.
3. Align the handle yoke hole that accepts the bolt with the receiving hole in the bottom of the handle. Once the holes are lined up, secure
the handle to the handle yoke with the bolt provided.
4. Move the handle assembly up and down while simultaneously pushing down on the lock lever until the locking rod engages one of
the locating holes in the handle yoke bracket. There are three holes in the handle yoke bracket that are used to lock the handle in either a
horizontal, angular or almost vertical position.
5. Install the quick disconnect of your choice in the back of the air valve. The air valve and hose are equipped with a loop that secures them
to the "L" shaped hook on the upper portion of the handle.
6. Secure the air valve and hose to the handle and connect a shop air line to the air valve.
7. Sometimes air gets trapped in the hydraulic system during shipment. An air bound hydraulic system feels spongy when pumped.
PURGING AIR FROM THE HYDRAULIC SYSTEM
a. Open the release valve by turning the knob at the top of the handle in a counterclockwise direction two full turns
from the closed position.
b. Depress the air valve for approximately 30 seconds.
c. Close the release valve by turning the knob in a clockwise direction until tight.
d. Depress the air valve until the ram raises to maximum height.
e. If the condition remains, repeat steps "a" through "d" until all the air is purged from the system.
OPERATING INSTRUCTIONS
This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential personal
injury hazards. Obey all instructions to avoid possible injury or death.
IMPORTANT: Before attempting to raise any vehicle, check vehicle service manual for recommended lifting surfaces.
1. Become familiar with the identification and function of the operating jack components.
a. The ram is the shaft that comes out of the jack when you depress the air valve and lifts the load.
b. The ram is equipped with an extension screw which can be unscrewed to extend from the ram if there is not enough hydraulic stroke to
raise the load to the desired height. If additional height is required, extension adapters can be inserted in the hole on top of the
extension screw.
c. Larger diameter saddles can be inserted in the extension screw when requiring a larger diameter saddle surface.
2. Chock the vehicle's tires that will not be lifted off the ground prior to lifting the vehicle and if available, apply the emergency brake or any
other method of braking.
3. Position the jack at the designated lift point. Estimate the required ram travel to raise the vehicle to the desired height. If the desired vehicle
height exceeds the entire ram travel, unscrew the extension screw to make up the difference and add an extension adapter if necessary.
4. Turn the knob at the top of the handle all the way in a clockwise direction until tight. Lock the handle in a position that will not interfere with
the vehicle when raised or lowered. Keep the handle in that locked position until the work is completed and you are ready to remove the
jack from use.
5. With the jack in the lowered position, push the jack under the vehicle. IMPORTANT: Use the vehicle manufacturer's recommended lifting
procedures and lifting points before lifting loads.
6. In most cases 100 P.S.I. input air pressure (do not exceed 200 P.S.I.) will lift the maximum capacity load not to exceed 22 tons. Depress the
air valve until the top of the ram comes close to the designated lift point. Make sure the designated lift point is flat, parallel to the ground
and free from grease, any kind of lubricant, and debris. Proceed with pumping the jack in order to lift the vehicle to the desired height.
During lifting, inspect the position of the jack in relation to the ground and the ram in relationship to the load to prevent any unstable
conditions from developing. If conditions look like they are becoming unstable, slowly lower the load and make appropriate setup
corrections after the load is fully lowered.
