PRODUCT DESCRIPTION
Blackhawk Hydraulic Service Jacks are designed to lift, not sustain, rated capacity loads. They are designed to be
used in conjunction with jack stands. Intended use: To lift one wheel or one axle of a vehicle for the purpose of 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. Always refer to the Product Label and Operator's
Manual to establish rated capacity.

SAFETY INSTRUCTIONS (refer to Figure 1 for location of components)
BEFORE USE
1. Verify that the product and the application are compatible, if in doubt call Blackhawk Automotive Technical
Service (816) 891-6390.
2. Read the operator's manual completely and familiarize yourself thoroughly with the product, its components and
recognize the potential hazards associated with its use before using this product.
3. Assemble handle, then secure it in the handle fork with the provided bolt. Open the release valve by turning the
handle counterclockwise (no more than 2 full turns).
4. With saddle fully lowered, locate and remove the oil filler plug. Pump the handle 6 to 8 full strokes. Ensure the oil
level is within ~ 3/16" from the inner cylinder as viewed from the oil filler plug. Reinstall the oil filler plug. Close
release valve by turning the handle clockwise until firm resistance is felt.
5. Check to ensure that jack rolls freely, that the pump and release valve operates smoothly, raises and lowers the
unloaded saddle throughout the advertised lift range before putting into service.
6. Replace worn or damaged parts and assemblies with Blackhawk Replacement Parts only. (See Replacement
Parts Section). Lubricate as instructed in Maintenance Section.
! WARNING
To avoid crushing and related injuries:
NEVER work on, under or around a load supported
only by a jack. ALWAYS use adequately rated jack
stands. Immediately transfer the load to adequately
rated jack stands.
• Study, understand, and follow all instructions
provided with and on this device before use.
• Do not exceed rated capacity.
• Lift only on areas of the vehicle as specified by the
vehicle manufacturer.
• Do not use adapters or accessories that are not
provided initially.
• This is a lifting device only. After lifting, immediately transfer the load to appropriately rated vehicle
stands.
• Never work on, under, or around a load supported
by this device.
• Use only on hard, level surfaces capable of sustaining rated capacity loads.
• Do not move or dolly loads with this device.
• Do not modify this device.
• Failure to heed these markings may result in
personal injury and/or property damage.
! WARNING
ASSEMBLY
Little, if any, assembly is required of these jacks. Always secure the handle into the handle fork 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 the operator's manual. Know your jack and how it operates before attempting to use.
OPERATION
Lifting
1. Place vehicle in park gear, with emergency brake on and wheels securely chocked to prevent inadvertent vehicle
movement.
2. Locate and close release valve by turning handle 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
1. Raise load high enough to clear the jack stands, then carefully remove jack stands (always used in pairs).

! ADVERTENCIA
! Safety Messages !
• Leer, comprender, y seguir las instrucciónes
antes de utilizar el aparato.
• El manual de instrucciónes y la información de
seguridad deben estar comunicado en lengua del
operador antes del uso.
• No seguir estas indicaciónes puede causar daños
personales o materiales.
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 malfunctioning jack and then the stands.
c. Using the functioning jack, lower the load by turning the operating handle counterclockwise, but no more than
1/2 turn.
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 Hein-Werner HW93291 hydraulic oil or equivalent.
Be sure all tools and personnel are clear before
lowering load. Only attachments and/or adapters
supplied by the manufacturer shall be used. Lift
only on areas of the vehicle as specified by the
vehicle manufacturer.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil filler plug hole. Reinstall the oil filler plug.
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 plug.
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.
3. Fill with oil until ~3/16" above the inner cylinder as seen from the oil filler plug hole. Reinstall the oil filler plug.
Lubrication
A coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that wheels,
casters 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.
Note: Never use sandpaper or abrasive material on these surfaces !
Storage
When not in use, store the jack with saddle fully lowered.
