Operating Instructions
Important: Sometimes during shipment and handling, air gets into the hydraulic system, causing poor
lifting performance. Before initial operation, purge any air from the system by fully opening release (turn
handle counter-clockwise). Then, while holding the saddle down, pump handle rapidly several times.
Raising the Jack
1.
Turn handle clockwise, until resistance is felt, to close release valve. Do not over tighten.
2.
Place jack directly under object to be lifted. Make sure saddle takes up weight firmly, and centrally.
Check positioning under slight load to confirm jack or load will not slip.
3.
Raise jack by pumping handle until desired height is reached. After lifting, secure load by
appropriate means. Do not use jack as the only means of support.
Lowering the Jack
1.
Slowly turn handle counter-clockwise. Speed of descent is controlled by how much the release valve
is turned.
Always store jack in the fully lowered position.
Troubleshooting
If jack fails to raise to its limit, remove oil fill plug (7, page 7). Fill with just enough quality hydraulic jack
fluid so that the jack raises to its limit.
