INTRODUCTION
Save these instructions. For your safety and the safety of others around you read this instructions
carefully before attempting to assemble, service or use your jack. Observe all safety and warning infor-
mation. Always wear safety glasses when operating this product. Failure to comply with the informa-
tion contained within could result in severe, even fatal injury and/or property damage.
PRODUCT DESCRIPTION
Air actuated / Hydraulic Hand Jacks are designed for lifting, but not sustaining, loads ranging from up
to 12 tons though 20 tons depending on the rated capacity of the jack. They can be used vertically or
angled to 5 degrees from vertical position. After lifting, loads must be immediately supported by appro-
priate means. Each model is suitable for use in an appropriately rated and designed vertical or bench
press structure. These jacks are not recommended for use in lifting or positioning houses and/or build-
ing structures. These jacks comply with applicable standards. For air actuated use, ensure that your
air source can dedicate is recommended.

BEFORE USE
1) Verify that the product and the application are compatible. Contact the manufacturer or an autho-
rized service partner.
2) Before using this product, read the owner’s manual completely and familiarize yourself thoroughly
with the product and the hazards associated with its improper use.
3) Open the release valve (counterclockwise not more than 2 full turns).
4) With ram fully retracted, locate and remove the oil filler plug. Insert the handle into the hand
sleeve, then pump 6 to 8 strokes. This will help release any pressurized air which may be trapped
within the reservoir. Ensure the oil level is just below the oil filler plug hole. Re-install the oil filler
plug.
5) Pour a teaspoon of good quality air tool lubricant into the air supply inlet of the lift control valve
(see illustration). Connect to air supply and operate 3 seconds to evenly distribute the lubricant.

6) Check to ensure that jack rolls freely (if equipped so) and that the pump operates smoothly before
putting into service. Replace worn or damaged parts and assemblies with original spare parts from
the manufacturer.
7) This product is fitted to accept the popular 1/4” PT air nipple. When installing 1/4” PT nipple of
your choice, ensure that thread tape or compound is used when servicing connections.
8) Inspect before each use. Do not use if bent, broken or cracked components are noted. Broken
parts must be repaired before the jack is taken into action again.
OPERATION
LIFTING
1) Assemble 2 pieces handle and ensure that spring clips align with slots.
2) Secure the load to prevent inadvertent shifting and movement.
3) Position the jack near desired lift point.
4) Close the release valve by turning it clockwise until it is firmly closed.
CAUTION: Use the handle provided with this product or an authorized replacement handle to ensure
proper release valve operation. Do not use an extender on the air hose nor the operating handle when
using to lift vehicle. Lift only on the manufacturer’s recommended lift point and in accordance with the
published guidelines in your vehicle owner’s manual. Always use the jac stands to support the load.
5) Insert and secure hand into hand sleeve. Pump handle or squeeze the lift control valve until sad-
dle contacts load. To end air operation simply release the grip on the lift control valve. EVER
WIRE, CLAMP OR OTHERWISE DISABLE THE LIFT CO TROL VALVE TO FU CTIO BY A Y
MEA S OTHER THA BY USI G THE OPERATOR’S HA D.
6) Raise load to desired height, then immediately transfer the load to appropriately-rated support de-
vices such as jack stands.
CAUTION: This is a lifting device only. It is designed to lift a part of the total vehicle (one wheel or
axle). Always wear safety glasses when using this equipment. Center the load on saddle before lifting.
Never wor on, under or around load until it is properly supported. Transfer the load immediately to
appropriate rated jac stands. Do not use this product for any purpose other than that for which
it was intended. It is the owner’s responsibility to eep labels and instructional material legible and
available. Replacement labels and manuals are available from the manufacturer. Failure to heed
these and all other warnings pertaining to this product can result in sudden loss of lifted load resulting
in death, personal injury and/or property damage.

LOWERING
1) Raise load enough to carefully remove jack stands.
2) Insert handle onto release valve and slowly turn the handle counterclockwise, but not more than
1/2 turn. If load fails to lower, carefully transfer the load to another lifting device and jack stands.
Carefully remove the affected jack, and then the jack stands. Lower the load again by slowly turn -
ing the release valve no more than 1/2 turn.
CAUTION: Be sure all tools and personnel are clear before lowering the load. Dangerous dynamic
shoc loads are created by quic ly opening and closing the release valve while the load is being low-
ered. The resulting overload may cause hydraulic system failure which could cause severe per-
sonal injury and/or property damage.
3) After removing jack from under the load, push the ram and handle sleeve down to reduce expo-
sure to rust and contamination.
MAINTENANCE
IMPORTA T: Use only a good grade hydraulic jack oil. Avoid mixing different types of fluid and
EVER use brake fluid, turbine oil, transmission fluid, motor oil or glycerin.
ADDING OIL
1) With saddle fully lowered and pump piston fully depressed, set jack in its upright level position and
remove the oil filler plug.
2) Fill until oil is level with the filler plug hole and reinstall the oil filler plug
CHANGING OIL
For best performance and longest life, replace the complete fluid supply at least once a year.
1) With saddle fully lowered and pump piston fully depressed remove the oil filler plug.
2) Lay the jack on its side and drain the fluid into a suitable container.
Note: Dispose hydraulic fluid in accordance with local regulations.
3) Fill with good quality jack oil. Reinstall oil filler plug. We recommend MOBIL DTE 13 or equivalent.
LUBRICATION
1) A coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and as-
sure that wheels, casters and pump assemblies move freely.
2) Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and
wipe with an oily cloth.
CAUTION: NEVER use sandpaper or abrasive material on these surfaces.
3) When not in use, store the jack with pump piston and ram fully retracted.
