service and/or repair of vehicle components. After lifting, loads must be immediately supported by appropriately rated
jack stands. Check with vehicle owner's manual for proper lift points.
DO NOT USE AS A WHEEL DOLLY !

BEFORE USE
1. Verify that the product and the application are
compatible.
2. Before using this product, read the owner's manual
completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards
associated with its use.
3. Locate and open the release valve (counterclockwise
no more than 1/2 full turn).
4. With saddle fully lowered, locate and remove the oil
filler screw. Insert the handle into the handle sleeve,
then pump 6 to 8 full strokes. This will help release
any pressurized air which may be trapped within the
reservoir. Ensure the oil level is ~3/16" above the inner
cylinder as seen from the oil filler screw hole. Reinstall
the oil filler screw.
5. Check to ensure that jack rolls freely and that the
pump operates smoothly before putting into service.
Replace worn or damaged parts and assemblies with
authorized factory replacement parts only (see
replacement parts section). Lubricate as instructed
in maintenance section.
6. Lift only on areas of the vehicle as specified by the
vehicle manufacturer.
7. No alterations shall be made to this product.
8. Do not use adapters or accessories that are not
provided initially.
! SAFETY MESSAGE !

WARNING
ASSEMBLY
Little, if any, assembly is required of this jack. Always
secure the handle into the handle sleeve by means of
the bolt and lock washer provided. Tighten securely to
prevent accidental removal of handle while in use.
Familiarize yourself with the illustrations in this owner's
manual. Know your jack and how it operates before
attempting to use.
OPERATION
Lifting
1. Place vehicle in park, with emergency brake on and
wheels securely chocked to prevent inadvertent vehicle
movement.
2. Locate and close release valve by turning handle knob
clockwise, firmly. Center jack saddle under lift point.
3. Verify lift point, then use handle pump to contact lift
point. To lift, pump handle until load reaches desired
height.
4. Transfer the load immediately to appropriately rated
jack stands.
Lowering
Note: Be sure all tools and personnel are clear before
lowering load.
1. Raise load high enough to clear the jack stands, then
carefully remove jack stands (always used in pairs).
2. Slowly turn the handle counterclockwise, but no more
than 1/2 turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough
to reinstall jack stands.
b. Remove the affected jack and then the stands.
c. Using the other jack, lower the load by turning the
handle knob counterclockwise, but no more than
1/2 turn.
3. After removing jack from under the load, push saddle
down to reduce ram exposure to rust and
contamination.
!
WARNING
To avoid crushing and
related injuries:
NEVER work on, under or
around a load supported
only by jack. ALWAYS
use adequately rated jack
stands.

MAINTENANCE
Important: Use only a good grade hydraulic jack oil.
Avoid mixing different types of fluid and NEVER use
brake fluid, turbine oil, transmission fluid, motor oil or
glycerin. Improper fluid can cause failure of the jack
and the potential for sudden and immediate loss of load.
We recommend Mobil DTE 13M or equivalent.
Adding oil
1. With saddle fully lowered set jack in its upright, level
position. Locate and remove oil filler screw.
2. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil filler screw hole. Reinstall the oil
filler screw.
3. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil filler screw hole. Reinstall the oil
filler screw.
Lubrication
A periodic coating of light lubricating oil to pivot points,
axles and hinges will help to prevent rust and assure
that wheels, castors and pump assemblies move freely.
Cleaning
Periodically check the pump piston and ram for signs
of rust or corrosion. Clean as needed and wipe with an
oily cloth.
Changing oil
For best performance and longest life, replace the complete fluid supply at least once per year.
1. With saddle fully lowered, remove the oil filler screw.
2. Lay the jack on its side and drain the fluid into a
suitable container.
Note: Dispose of hydraulic fluid in accordance with local
regulations.
