If the jack can raise the load by way of activating the jack's air valve (#P53) but the rams are not extending smoothly, there may be air trapped
in the second stage cylinder.
1.
With the breather screw (#26) loosened, turn the release handle (#53) two complete revolutions in the counterclockwise direction.
Make sure the jack is hooked up to compressed air.
2.
Depress the jack's air valve (#P53) so the jack's air pump is operating for 30 to 60 seconds.
3.
Tighten the release handle (#53) by turning clockwise until it stops. Depress the jack's air valve (#P53) to see if the condition has
been eliminated. If better but not eliminated, repeat steps 1 through 3 several times.
4.
If the condition still exists, activate the foot pedal (#47) until both rams are at full extension. Loosen the M8 X 10 Allen socket
screw in the second stage cylinder (#67) by turning it in a counterclockwise direction ½ turn. Activate the pump pedal
(#47) very slowly until you see hydraulic fluid escaping from the M8 X 10 screw hole. Hold pressure on the pump pedal and
simultaneously tighten the M8 X 10 screw.
5.
Turn the release handle (#53) in a counterclockwise direction to see if the rams descend smoothly. If not, repeat step 4 several times.
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.
1.
Lift the vehicle to the desired work height and support the vehicle in accordance with the lift manufacturer's recommended
support procedure and all the instructions and warnings in this manual.
2.
Use an under hoist stand rated greater than the weight of the engine to support the engine before unbolting the transmission from
the engine or bolting the transmission to the engine.
3.
Position the transmission jack directly under the transmission. The transmission jack's saddle can be raised by either foot pump
operation or depressing the air valve but 100 psi of compressed air will be necessary to lift 2,000 pounds by way of the air valve.
Also, the release valve handle

pull the tie down across the top of the transmission and install the other hook end of the tie down in the loop directly across
from the other one. The tie down is a clam operated version that will tighten by pulling on the loose end of the tie down strap.
IMPORTANT: Never remove, install or transport a loaded jack without first following this step 6.
7.
Make sure the tie down strap is very tight when securing the transmission to the saddle and before removing the under hoist
stand that has been supporting the engine.

PREVENTATIVE MAINTENANCE
This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury or death. IMPORTANT: Any jack found to be defective
as a result of worn parts due to lack of lubrication or air/hydraulic system contaminated with water, rust and /or foreign
materials from the air supply or other outside source is not eligible for warranty consideration.
1.
Always store the jack in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust, or
any other harmful elements. The jack must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter before using.
2.
Lubricate moving parts, excluding the telescopic rams, monthly with a general purpose grease.
IMPORTANT: Any jack found to be defective as a result of worn parts due to insufficient or lack of lubrication is not eligible
for warranty consideration.
