General Operating Instructions
Lifting
WARNING
Park vehicle on a flat, level, solid, surface safely away from oncoming
traffic. Turn off the vehicle’s engine. Place the vehicle’s transmission in
“PARK” (if automatic) or in its lowest gear (if manual). Set the vehicle’s
emergency brake. Then, chock the wheels that are not being lifted.
-
Turn the Handle counterclockwise to lower the Jack. Once the Jack is fully lowered, turn the Handle firmly clockwise to close it.
-
Carefully position the Saddle of the Jack under the vehicle manufacturer’s recommended lifting point. (See vehicle manufacturer’s owner’s manual for location of frame lifting point.)
-
Pump the Handle until the top of the Jack’s Saddle has nearly reached the vehicle lifting point. Position the Saddle directly under the vehicle’s lifting point.
-
To lift the vehicle, pump the Handle of the Jack. Use smooth, full strokes.
-
Once the vehicle is raised, slide a jack stand of appropriate capacity (not included) under a proper lifting point referred to in the vehicle owner’s manual. Always use two jack stands, position them at the same point on each side of the vehicle.
CAUTION! The rated capacity of jack stands is per pair, not the individual capacities combined unless specifically noted on the product by the jack stand manufacturer. Do not exceed rated jack stand capacity. Ensure that the vehicle support points are fully seated in the saddle of both jack stands. Use a matched pair of jack stands per vehicle to support one end only. Failure to do so may result in the load suddenly falling, which may cause personal injury and/or property damage. -
Center the vehicle’s lifting point(s) on the saddle of the jack stand(s). Set the jack stand(s) to the same height according to the manufacturer’s instructions, making sure that they lock securely into position.
-
Slowly turn the Handle counterclockwise to lower the vehicle onto the saddle(s) of the jack stand(s). Then, turn the Handle firmly clockwise to close it.
Lowering
- Carefully remove all tools, parts, etc. from under the vehicle.
- Position the Saddle under the lifting point. Turn the Handle firmly clockwise and raise load high enough to clear the jack stands, then carefully remove jack stands.
- Slowly turn the Handle counterclockwise (never more than 1/2 full turn) to lower the vehicle onto the ground.
- Lower the Jack completely. Then, store in a safe, dry location out of reach of children.
- To prevent accidents, turn off the tool and disconnect its power supply after use. Clean, then store the tool indoors out of children’s reach.
Maintenance and Servicing
Procedures not specifically explained in this manual must be performed only by a qualified technician.
WARNING
TO PREVENT SERIOUS INJURY FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal noise or vibration occurs, have the
problem corrected before further use.
Cleaning, Maintenance, and Lubrication
-
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. -
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. -
Change the hydraulic oil at least once every three years:
- With the Jack fully lowered, remove the Oil Filler Plug on the side of the Housing.
- 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.
- With the Jack upright, completely fill the Housing with a high quality hydraulic oil (not included) until the oil is 1/4″ below the fill hole.
- Open the valve by turning the Handle counterclockwise and pump the Handle to bleed air from the system.
- Recheck oil level and re-fill as needed.
- Reinstall the Oil Filler Plug.
-
Wipe dry with a clean cloth. Then, store the Jack in a safe, dry location out of reach of children and other non-authorized people.
Troubleshooting
WARNING
TO PREVENT SERIOUS INJURY:
Use caution when troubleshooting a malfunctioning jack. Stay well clear of the
supported load. Completely resolve all problems before use. If the solutions
presented in the Troubleshooting guide do not solve the problem, have a
qualified technician inspect and repair the jack before use.
After the jack is repaired: Test it carefully without a load by raising and
lowering it fully, checking for proper operation, BEFORE RETURNING THE JACK TO
OPERATION.
DO NOT USE A DAMAGED OR MALFUNCTIONING JACK!
