SAFETY INSTRUCTIONS
BEFORE USE
1. 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.
2. Verify that the product and the application are compatible, if in doubt call Blackhawk Automotive Technical Service
(816)891-6390.
3. Inspect before each use. Do not use if there are bent, cracked or damaged parts (including labels).
4. Locate and open the release valve (counterclockwise no more than 1/2 full turn).
5. With saddle fully lowered, locate and remove the oil filler plug. 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 just below the oil filler plug hole. Reinstall the oil filler plug.
6. For the Air/ Lever Actuated model, pour a teaspoon of good quality air tool lubricant into the air supply inlet of the lift control valve. Connect to air supply and operate for 3 seconds to evenly distribute lubricant.
7. 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 Blackhawk Automotive Authorized Replacement Parts only (see Replacement Parts Section). Lubricate as instructed in Maintenance Section.

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 release valve 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
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 knob 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 malfunction jack and then the stands.
c. Using the other 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.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug.
2. Ensure the oil level is just below 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. Ensure the oil level is just below the oil filler plug hole. Reinstall the oil filler plug.
