SETUP

Initial tool Set up
Read the ENTIRE IMPORTANT SAFETY INSTRUCTIONS section at the beginning of this manual Including all text under subheadings therein before set up or use of this product.
Components and Controls
Bleeding Instructions
Before each use or if Jack performance decreases, check for excessive air and proper hydraulic fluid level in Jack. If Jack appears not to be working properly, it may be necessary to purge its hydraulic system of excessive air as follows:

1. Assemble the Jack Handle by pushing the two sections together.

2. Remove Fill Plug. Fill with hydraulic fluid (sold separately) to full level, if necessary.

3. Place the slotted end of the Jack Handle over the Release Valve, then turn counterclockwise to open the Release Valve.

4. Insert the Jack Handle into the Fulcrum, apply downward pressure to the Saddle, then pump the Jack Handle quickly several times.

5. Check fluid level and, if necessary, top off with hydraulic fluid.

6. Close the Release Valve by turning it clockwise, then replace Fill Plug.
   IMPORTANT: After bleeding the Jack, test the Jack for proper operation prior to its actual use.

7. If, after bleeding, the Jack does not appear to be working properly, do not use it until repaired by a qualified service technician.

Air Supply
TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Use only clean, dry, regulated, compressed air to power this tool. Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool.

1. Incorporate a filter, regulator with pressure gauge, oiler, in-line shutoff valve, and quick coupler for best service, as shown on Figure A: Portable Air Supply Setup on page 6 and Figure B: Stationary Air Supply Setup on page 7. An in-line shutoff ball valve is an important safety device because it controls the air supply even if the air hose is ruptured. The shutoff valve should be a ball valve because it can be closed quickly.
   Note: If an automatic oiler system is not used, add a few drops of Pneumatic Tool Oil to the airline connection before operation. Add a few more drops after each hour of continual use.

2. Attach an air hose (not included) to the compressor’s air outlet. Connect the air hose to the Jack’s Air Inlet. Other components, such as a connector and quick coupler, will make operation more efficient, but are not mandatory.
   WARNING! TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
   Do not install a female quick coupler on the tool. Such a coupler contains an air valve that will allow the air tool to retain pressure and operate accidentally after the air supply is disconnected.
   Note: Air flow, and therefore tool performance, can be hindered by undersized air supply components. The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.

3. Turn the tool’s throttle or switch to the off position; refer to Operation section for description of controls.

4. Close the in-line shutoff valve between the compressor and the tool.

5. Turn on the air compressor according to the manufacturer’s directions and allow it to build up pressure until it cycles off.

6. Adjust the air compressor’s output regulator so that the air output is enough to properly power the tool, but the output will not exceed the tool’s maximum air pressure at any time. Adjust the pressure gradually, while checking the air output gauge to set the right pressure range.

7. Inspect the air connections for leaks. Repair any leaks found.

8. If the tool will not be used at this time, tum off and detach the air supply, safely discharge any residual air pressure, and release the throttle and/or turn the switch to its off position to prevent accidental operation.
   Note: Residual air pressure should not be present after the tool is disconnected from the air supply. However, it is a good safety measure to attempt to discharge the tool in a safe fashion after disconnecting to ensure that the tool is disconnected and unpowered.

4. Pneumatic Operation:
   a. Connect the compressor’s air hose to the Air Inlet
   b. Release the Air Lever Lock, then depress the Air Lever until the Saddle has nearly reached the vehicle lifting point.
   c. Position the Jack at 90° to the vehicle’s lifting point to ensure the Saddle and vehicle lifting point are in alignment. If they are not, reposition the Jack before lifting.
   d. Continue to depress the Air Lever. Once the vehicle is raised, place the Air Lever Lock in its locked position.
   Note: If the tool requires more force to accomplish the task, verify that the tool receives sufficient, unobstructed airflow (CFM) and increase the pressure (PSI) output of the regulator up to the maximum air pressure rating of this tool.
   CAUTION! TO PREVENT INJURY FROM TOOL OR ACCESSORY FAILURE:
   Do not exceed the tool’s maximum air pressure rating.
   If the tool still does not have sufficient force at maximum pressure and sufficient airflow, then a larger tool may be required.

5. Manual Operation:
   a. Place the Jack Handle into the Handle Bracket.
   b. Pump the Jack Handle until the Saddle has nearly reached the vehicle lifting point.
   c. Position the Jack at 90° to the vehicle’s lifting point to ensure the Saddle and vehicle lifting point are in alignment. If they are not, reposition the Jack before lifting.
   d. Continue to pump the Jack Handle until the vehicle is raised.

6. Set properly-rated jack stands (not included) to the same minimum practical height according to the manufacturer’s instructions, making sure they lock securely into position.

7. Position the jack stand saddles under the vehicle manufacturer’s recommended support points.
   WARNING! TO PREVENT SERIOUS INJURY: Ensure that the vehicle support points are fully seated in the saddles of both jack stands. Use a matched pair of jack stands per vehicle to support one end only.

8. Place the slotted end of the Jack Handle over the Release Valve and slowly turn the Release Valve counterclockwise to lower the vehicle onto the saddles of the jack stands.
