OWNER'S MANUAL
SETUP
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. Remove the bolt (19) from under the handle yoke (21). Insert the handle tube (6) in the handle yoke (21) while simultaneously inserting the
locking rod (18) in the handle yoke guide holes.
2. Raise the lock lever (11) 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 (1) at the top of the handle back and forth until you feel the bottom of the handle engage the release valve fitting
(33) 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 (19) provided.
4. Move the handle assembly (6) up and down while simultaneously pushing down on the lock lever (11) until the locking rod engages one
of the locating holes in the handle yoke bracket (22). 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 (61) of your choice in the back of the air valve (4). 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).
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.
TO PURGE AIR FROM THE HYDRAULIC SYSTEM:
a. Open the release valve by turning the knob (1) at the top of the handle in a counterclockwise direction two full turns from the
closed position.
b. Depress the air valve (72) for approximately 30 seconds.
c. Close the release valve by turning the knob (1) 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.
7. When the vehicle or load is lifted to its desired height, immediately place safety support stands (jack stands) in their designated
locations and adjust the stands' support columns up as close to the designated vehicle support points as possible. Although jack
stands are individually rated, they are to be used in a matched pair to support one end of the vehicle only. Stands are not to be used to
simultaneously support both ends or one side of a vehicle. Slowly and carefully turn the release knob in a counterclockwise direction to
gently lower the vehicle onto the safety support stands (jack stands). Make sure the vehicle is safely supported by the safety support
stands' (jack stands) saddles and not the locating lugs of the saddles. Inspect the relationship of the safety support stands (jack stands)
with the ground and the safety support stand (jack stand) columns and saddles with the vehicle to prevent any unstable conditions. If
conditions look unstable, close the jack's release knob and depress the air valve to raise the vehicle off the safety support stands (jack
stands). Make the appropriate setup changes and slowly and carefully lower the vehicle onto the safety support stand saddles.
8. After the work is done, close the release knob and depress the air valve until the jack is high enough to remove the vehicle or load from
the safety support stand saddles. Be sure load is stable. If it is not, lower load back onto safety support stands. Make appropriate setup
