To avoid serious injury or death, read this manual carefully before operating this unit. Contact customer service if you
have any questions.
Failure to understand and obey safety instructions may result in unsafe or improper use of this product.
1. Do not overload. Maximum capacity is 50,000 lb. / 22,680 kg.
2. Use this jack only on hard level surfaces capable of sustaining the load. Use on other than hard level surfaces can
result in jack instability and possible loss of load.
3. Select the lifting point with care. It must be strong enough to sustain the lifting force without damage to the vehicle.
It is necessary to cradle the lifting point in the lift pad to insure that the selected lift point will not shift or tilt which
could cause loss of load resulting in bodily injury or property damage.
4. This jack is designed solely for the lifting of vehicles only, (Use of the jack for any other purpose constitutes misuse
of the jack), and must never be used to support a load. After raising a vehicle, never allow any part of your body to
pass under it and never begin work on the vehicle until it is properly supported by adequate stands.
5. Once the vehicle is properly supported be adequate stands, the jack must be removed from beneath the vehicle
before work on the vehicle begins.
6. No alterations shall be made to this product.
7. Always lift with either the factory supplied lift pad or lift pad extension in place.
Never lift when one of these two factory furnished lift pads is not properly installed.
Do not use any kind of cribbing or adapters with this jack. The jack must remain in
direct contact with the oor and the lifting pad must be in direct contact with the
vehicle. See illustration to the right.
8. Never use more than one jack at the same time to lift a vehicle. If a jack does not have enough capacity to raise a
load, remove it and use a jack with adequate capacity. Failure to observe this instruction may lead to unstable or
overload conditions that could cause failure of one or both of the jacks.
9. Do not drive the vehicle off of the jack, or attempt to move the vehicle at any time while the jack supports it.
Failure to understand and obey this warning may result in personal injury and / or property damage.

PROPER INSTALLATION OF LIFT PAD

All inspection and maintenance procedures must be performed after the jack has been removed from service.
Failure to heed this warning may result in personal and / or property damage.
!WARNING
OPERATING INSTRUCTIONS
Connect a quick coupler to the air control valve inlet. Close the release valve by rotating the release knob clockwise.
Attach air supply of 90-PSI minimum to 200 PSI maximum. The unit is now ready for use. Actuation of the air control
lever will now raise the lift pad. Rotating the release knob counter-clockwise will lower the lift pad.
Rapid Raising of lift pad to Contact Load: Upon actuating the air control valve, the jack lift pad will rise quickly until
contact is made with the load. Then the jack will continue to lift the load (at a slower rate) until the air control valve is
released or the jack has reached the limit of its stroke.
Air Powered Ram Retraction: The ram will retract by leaving the air supply connected and the release valve open. The
ram will fully retract even under no load conditions.
MAINTENANCE INSTRUCTIONS
Check oil level in the oil reservoir. Refer to the “Adding Hydraulic Fluid” section.
All warning and capacity labels should be readable and complete. Wash external surfaces of jack and decals with a
mild soap solution.
Lubricate all rotating and sliding portions of the jack monthly.
The jack must be removed from service and inspected for damage immediately if the jack is subjected to an
abnormal shock or load. Failure to heed this warning may result in personal and / or property damage
!WARNING
NOTICE: The owner must inspect, or appoint a knowledgeable person to inspect the jack for signs of corrosion and /
or excessive wear. Regular inspections should be made weekly for daily use and monthly for intermittent use.
Inspect lift pad regularly and replace if it is cracked, chipped or shows signs of excessive wear.
The ram should extend and retract smoothly through its full range. Inspect the ram for scratches and dents, which
prevent normal operation.
Inspect for oil leaks. Operate jack for signs of oil blowing form the exhaust ports.
If any irregularities or problems are detected during an inspection, the jack must be removed from service immediately
and repaired. Contact customer service.
STRUCTURAL INSPECTION
7
The jack must be removed from service and inspected for damage immediately if the jack is subjected to an
abnormal shock or load. Failure to heed this warning may result in personal and / or property damage
!WARNING
ADDING HYDRAULIC FLUID
Remove the jack from service.
Make sure ram is fully retracted.
Disconnect airline.
Carefully remove the plastic cover from the oil reservoir plug located on the top surface of the jack body.
Make sure the hole for the oil reservoir plug is clean and dry before removing plug. Water and dirt destroy hydraulic
parts.
Remove oil reservoir plug using a 3/16" Hex wrench.
Check uid level. RAM MUST BE FULLY RETRACTED. The oil should be within 1/4 inch of the bottom of the oil ll
hole. If uid is low, add a high-grade hydraulic uid equivalent to Mobil Tellus T22 oil. Do not use brake or transmis-
sion uid.
Reinstall and secure the oil reservoir plug, replace the plastic cover, and connect to air supply and test for normal
operation.
TROUBLESHOOTING
This section is a list of possible problems, which may be encountered, and their solutions. If the solution listed fails to
correct the problem, contact customer service. Please have the model number, and serial number of your jack available.
The serial number is permanently stamped on the top of the frame.
PROBLEM CAUSE / SOLUTION
Fails to lift load
Low oil level, see “Adding Hydraulic Fluid”.
Inadequate air pressure, requires 90 PSI min.
Release open, turn release knob clockwise until tight.
Air line leaks, locate and correct leaks.
Overloaded, use larger capacity jack.
Fails to hold load Release open, turn release knob clockwise until tight.
Air motor won't run Airline leaks, locate and correct leaks.
Inadequate air pressure, requires 90-psi minimum.
Oil leaks Oil reservoir plug loose, tighten ll oil reservoir plug.
