OWNER'S MANUAL
SETUP INSTRUCTIONS
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1.
Assemble the two handle halves together using the bolt and locknut provided, making sure the release shaft guide tabs are on the
same side of the handle.
2.
Insert the release shaft with knob through the top handle guide tab and then through the bottom handle guide tab.
3.
The second release shaft half has a receiver on its end. Install the end of the release shaft with knob into the receiving end of the
second release shaft receiver and secure them together with the screw provided.
4.
Insert the handle assembly in the handle receiver of the jack base while simultaneously inserting the end of the release shaft into the
release valve receiver at the base of the jack. Align the hole in the handle tube with the hole in the handle receiver of the jack and
secure with the bolt and lock nut provided. Secure the release shaft to the release valve receiver with the screw provided.
5.
Install the air quick disconnect of your choice in the air valve at the end of the hose. Affix the air valve to the "L" shaped bracket on
the handle. Hook the shop's system air hose up to the air valve.
6.
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 15 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. 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.
OPERATION:
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.
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. Turn the knob at the top of the handle all the way in a clockwise direction until tight.
4.
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.
5.
In most cases 100 psig input air pressure (do not exceed 200 psig) will lift the maximum capacity load not to exceed 20 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.
6.
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. DO NOT
CRAWL UNDER VEHICLE WHILE LIFTING VEHICLE OR PLACING OR REMOVING THE JACK STANDS.
7.
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 corrections and repeat the step again. Remove the safety support stands from under the vehicle being very careful not to move
the vehicle.
8.
Turn the release knob in a counterclockwise direction very slowly and carefully to lower the vehicle or load down to the ground.
