SAFETY INSTRUCTIONS
BEFORE USE
1. Inspect the jack before each use. Do not use if there are bent, broken or cracked components.
2. Verify that the product and the application are compatible, if in doubt call Blackhawk Automotive Technical Service
(816) 891-6390.
3. 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.
4. Open the release valve counterclockwise no more than 2 full turns.
5. Locate and remove the oil filler screw with ram fully retracted (refer to Replacement Parts section).
NOTE: This will help release any pressurized air which may be trapped within the reservoir.
6. Ensure the oil level is just below the oil filler screw hole.
7. Reinstall the oil filler screw.
8. Pour a teaspoon of good quality air tool lubricant into the air supply inlet of the lift control valve.
9. Connect to air supply and operate for 3 seconds to evenly distribute lubricant.
10. Ensure that jack rolls freely and that the air pump operates smoothly before putting into service.
IMPORTANT: Replace worn or damaged parts and assemblies with Blackhawk Authorized Replacement Parts only.
NOTE: 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. To ensure dependable, trouble free
operation an inline air dryer and oiler is recommended.

vided with and on this device before operating this
device.
• Do not exceed rated capacity.
• Use the device only on a hard, level surface.
• This is a lifting device only.
• Immediately after lifting, support the vehicle with ap-
propriate means such as jack stands.
• Never wire, clamp or otherwise disable the lift con-
trol valve to function by other than operator's hand.
• Do not modify or alter this device.

ASSEMBLY
Little, if any, assembly is required of this jack; refer to figure 1 and figure 2 for components location. Familiarize yourself
with the illustrations in the operator's manual. Know your jack and how it operates before attempting to use. Assemble
handle to the handle fork. Secure the handle with provided bolt to prevent inadverent removal. Connect to adequate air
source and ensure air control valve is secured into the pipe nipple of the jack.
OPERATION
Lifting
1. Use wheel chocks to help prevent inadvertent shifting and movement of vehicle being lifted.
2. Position the jack near lift point. Consult vehicle service manual for the location of recommended lift points.
3. Close the release valve by turning the handle mounted knob, clockwise until it is firmly closed.
Important: Never wire, clamp or otherwise disable the lift control valve to work by any means other than by using
the operators hand.
Caution: Use only saddle extenders (if equipped) provided and recommended by the manufacturer of the jack. Lift
only on the manufacturer’s recommended lift points and in accordance with the published guidelines in your vehicle
owners manual. Always use jack stands to support the load immediately after lifting.
4. Squeeze the lift control valve until saddle contacts load. Check to ensure proper saddle/lift point alignment. To end
cycle, simply release the grip on the lift control valve.
5. Raise load to desired height, then immediately transfer the load to appropriately rated support devices such as
jack stands.
Lowering
1. Raise load high enough to clear the jack stands, then carefully remove jack stands (always used in pairs).
2. Slowly turn the release valve 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 release valve counterclockwise, but no more than 1/2 turn.
3. Push ram and handle sleeve down to reduce exposure to rust and contamination after removing jack from under
the load.
MAINTENANCE
Important: Use only a good grade hydraulic jack oil. We recommend Hein-Werner HW93291 hydraulic oil. Avoid
mixing different types of fluid and NEVER use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper
fluid can cause premature failure of the jack and the potential for sudden and immediate loss of load.
Adding oil
1. Lower saddle fully and fully depress piston.
2. Set jack in its upright, level position.
3. Remove oil filler screw.
4. Fill with oil until just below the rim of the oil filler screw hole.
5. Reinstall the oil filler screw.
Changing oil
For best performance, replace the complete hydraulic fluid annually.
1. Remove the oil filler screw with saddle fully lowered.
2. Lay the jack on its side and drain the fluid into a suitable container.
3. Fill with oil until just below the rim of the oil filler screw hole.
4. Reinstall the oil filler screw and cover plate.
Note: Dispose of hydraulic fluid in accordance with local regulations.
5
LUBRICATION
1. A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
pump assemblies move freely.
2. When used on a daily basis, air pump should be internally lubricated before each use. Use only good quality air
tool lubricant. If no inline oiler is used, pour a teaspoon of air tool oil into the inlet of the air control valve. Simply
operate the jack using the air feature in order to fully distribute the oil.
CLEANING
Periodically check the 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
Store the jack with ram fully retracted and air supply disconnected when not in use.
