Operating Instructions

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document including all text under subheadings therein before set up or use of this product.
Bleeding
IMPORTANT! Before first use, check for proper hydraulic oil level in the Jack. Then thoroughly test the Jack for proper operation prior to its actual use. If the Jack appears not to be working properly, it may be necessary to bleed its hydraulic system of excess air.

1. Check oil level, see instructions on page 7, “3. Before each use, check oil level:”

2. Place the lower portion of the Handle over the Release Valve and open it by turning it counterclockwise.

3. Insert the Handle into the Fulcrum and pump about five times. Apply pressure to the Saddle and pump Handle quickly several more times to remove trapped air in the Ram.

4. Carefully use a flat dull-sided edge to push down the top inside rim of the Oil Fill Plug to equalize pressure inside the Pump, then release the Oil Fill Plug.
   Note: Do not use a sharp edge as it may damage the plug.

5. Turn the Handle clockwise to close the Release Valve.

6. Test the Jack several times for proper operation before attempting to lift a load.
   If, after purging, the Jack still does not appear to be working properly, do not use the Jack until it has been repaired by a qualified service technician.

Lifting
WARNING! TO PREVENT SERIOUS INJURY: Set Jack on a flat, level, solid, ground surface. If using with vehicle, set safely away from oncoming traffic and turn off  vehicle’s engine. Also place the vehicle’s transmission in “PARK” (if automatic) or in its lowest gear (if manual). Set the vehicle’s emergency brake. Then, block the wheels that are not being lifted.

1. Place the lower portion of the Handle over the Release Valve and turn the Handle counterclockwise to lower the Jack. Once the Jack is fully lowered, turn the Handle firmly clockwise to close the Release Valve.

2. Carefully position the Saddle of the Jack under the vehicle manufacturer’s recommended lifting point. The Elevating Screw can be used to alter the height of the Jack’s Saddle; it is adjusted by turning it clockwise or counterclockwise. (See vehicle manufacturer’s owner’s manual for location of seam lifting point when lifting only one wheel and frame lifting points when lifting the entire front or rear end of the vehicle.)

3. Place the Handle in the Fulcrum and pump until the top of the Jack’s Saddle has nearly reached the vehicle lifting point.
   Note: The Jack should be positioned at 90° to the vehicle’s lifting point to ensure the Jack’s Saddle and vehicle lifting point are in alignment. If not, remove and reposition the Jack before lifting the vehicle.

4. To lift the vehicle, pump the Handle of the Jack. Use smooth, full strokes for best results.

5. Once the vehicle is raised, slide a jack stand of appropriate capacity (not included) to the proper lifting point referred to in the vehicle owner’s manual. If using two jack stands, position them at the same point on each side of the vehicle.

6. Center the vehicle’s lifting point(s) on the saddle of the jack stand(s). Set up the jack stand(s) according to the manufacturer’s instructions, making sure that they lock securely into position.
   Note: If using two jack stands they must be at the same height.

7. Place the Handle over the Release Valve and slowly turn the Handle counterclockwise to open the Release Valve and lower the vehicle onto the saddle(s) of the jack stand(s). Then, turn the Handle firmly clockwise to close the Release Valve.

Lowering

1. Remove all tools, parts, etc. from under the vehicle.
2. Position the Saddle under the lifting point. Place Handle over Release Valve and turn the Handle firmly clockwise to close the Release Valve.
3. Move the Handle to the Fulcrum and pump to raise the vehicle slightly above the saddle(s) of the jack stand(s). Then, collapse and remove jack stand(s).
4. Move the Handle back to the Release Valve and slowly turn the Handle counterclockwise (never more than two full turns) to lower the vehicle onto the ground.
5. Lower the Jack completely. Then, store in a safe, dry location out of reach of children.

Maintenance and Servicing Instructions

Procedures not specifically explained in this manual must be performed only by a qualified technician.
WARNING
TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use.
Cleaning, Maintenance, and Lubrication

1. Before each use, inspect the general condition of the Jack. Check for broken, cracked, or bent parts, loose or missing parts, and any condition that may affect the proper operation of the product. If a problem occurs, have the problem corrected before further use. Do not use damaged equipment.

2. Before each use, thoroughly test the Jack for proper operation prior to its actual use. If the Jack appears not to be working properly, follow Bleeding instructions on page 4.

3. Before each use, check oil level:
   a. Open Release Valve by turning it counterclockwise. Lower the Jack to its lowest position. Press down on the Saddle if necessary.
   b. With the Jack upright in a level, vertical position and the Handle pointing down in the Fulcrum, carefully remove the Oil Fill Plug. The oil level should be level with the bottom of Oil Fill hole. Top off if necessary but do not overfill. Always fill with clean hydraulic jack oil (not included).
   c. Reinstall Oil Fill Plug and close Release Valve by turning it clockwise. Check Jack operation. Bleed air from system as needed, see instructions on page 4.

4. Change the hydraulic oil at least once every three years:
   a. With the Jack fully lowered, remove the Oil Fill Plug on the side of the Housing.
   b. Tip the Jack to allow the old hydraulic oil to drain out of the Housing completely, and dispose of the old hydraulic oil in accordance with local regulations.
   c. With the Jack upright, completely fill the Housing with a high quality hydraulic oil (not included) until the oil just begins to run out of the Oil Fill hole.
   d. Then, reinstall the Oil Fill Plug and check jack operation. Bleed air from system as needed, see instructions on page 4.

5. Clean with a clean cloth with a detergent or mild solvent. Then, store the Jack in a safe, dry location out of reach of children and other non-authorized people.
