SAFETY INSTRUCTIONS
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 and the hazards associated
with its improper use before using this product.
3. With ram fully retracted, locate and remove the oil filler plug. Insert the handle into the handle 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. Reinstall the oil filler plug.
4. Ensure the pump operates smoothly before putting into service. Replace worn or damaged parts and assemblies
with Blackhawk Authorized Replacement Parts only. (See Replacement Parts Section). Lubricate as instructed in
Maintenance Section.
5. Inspect before each use. Do not use if there are bent, broken, or cracked components (including labels) are noted.
For air actuated model BH2081 only:
6. The jack comes with the popular 1/4" NPT air nipple and it's preassembled. When installing 1/4" NPT nipple of your
choice, ensure that thread tape or compound is used when servicing connections. To help ensure trouble free
operation, an inline air dryer and oiler is recommended.
7. 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.
