SETUP
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. Install the handle assembly (#79) in the housing (#74)
so the holes in the lower portion of the handle line up
with the holes in the housing. Push the handle yoke
pivot shaft (#81) through all the holes and secure the
shaft on both ends with the retaining rings provided.
2. Turn the entire jack on its side in order to hook up the
clear and black air hoses that are coming out of the
bottom of the handle (#79). As you are facing the back
of the jack, pull the clear and black hoses back towards
you and route them over the top of the pivot shaft (#81)
so that they are in line to engage the connectors in
the back of the tank (#105). Firmly push the black hose
into the connector labeled "black tube" and the clear
hose into the connector labeled "clear tube".
Pull on both hoses after they are installed into the
connectors to make sure they are firmly seated. Turn
the jack upright.
3. Install an air nipple that is suitable for your shop in the
switch assembly (#77). Use pipe dope tape to seal the
nipple in the switch assembly and be careful not to let
any excess tape enter the air system. Do not
over-tighten the nipple as this could strip the threads
in the switch.
4. Install the lever (#106) in the switch assembly (#77) and tighten.
5. Install the adapters (#75) in the holder at the base of the housing.
6. Hook the shop air line quick disconnect onto the nipple.
7. Due to the back pressure release system design of this jack, the jack's hydraulic system very rarely becomes air bound. Indication of an
air bound system is a ram that does not rise smoothly. In some extreme case of an air bound system, air can be purged by following
this procedure:
PURGING AIR FROM THE HYDRAULIC SYSTEM
a. Pump the jack to maximum height by turning the air lever all the way to the right. After maximum height is reached, turn the air
lever to the left to lower the jack all the way down.
b. Repeat step "a" several times until all 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.
OPERATION:
1. Become familiar with the identification and function of the operating jack components.
a. The rams (#95 and #100) are the shafts that come out of the jack when you rotate the switch assembly lever (#106) to the right.
Lowering the ram is accomplished by rotating the lever to the left.
b. The saddle (#99) has a hole in it to receive the adapters (#75). The adapters can be stacked on top of each other for
additional height. Evaluate the work to be done to determine if there is enough ram stroke to lift the load. Adding adapters can
bring the jack closer to the load so you can get more effective ram stroke.
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. With the jack in its lowered position and the handle all the way down and locked, push the jack under the vehicle and to its designated
lift point. 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.
4. In most cases, between 116 and 174 psig input air pressure (do not exceed 200 psig) will lift the maximum capacity load. Rotate the
air lever to the right 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. Never get under the vehicle when the jack is being used.
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 lowered.
DO NOT CRAWL UNDER THE VEHICLE TO POSITION OR REMOVE STANDS.
5.
height, immediately place jack stands capable of safely supporting the load in their designated positions and adjust the stands' support
columns up as close to the designated vehicle support points as possible. Although ljack stands are individually rated, they are 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. Rotate the air lever to the left to lower the vehicle onto the jack stands. Make sure the vehicle is safely supported by the jack
stands' saddles and not the locating lugs of the saddles. Inspect the relationship of the jack stands with the ground and the jack stand
columns and saddles with the vehicle to prevent any unstable conditions. If conditions look unstable, rotate the air lever to the right to
raise the vehicle off the jack stands. Make appropriate setup changes and slowly and carefully lower the vehicle onto the jack stands.
