 WARNING
1. This is a lifting device only. Do not move or dolly the vehicle while on the jack. The load shall be
supported immediately by other appropriate means.
2. Do not overload. Overloading can cause damage to or failure of the jack.
3. Lift only on areas of the vehicle specified by the vehicle manufacturer.
4. This jack is designed for use on hard, level surfaces capable of sustaining the load. Use on other
than hard, level surfaces can result in jack instability and possible loss of load.
5. Do not get under vehicle while jack is being used as the only support.
6. If jack needs service, contact your local JET distributor for the location of the closest JET Service
Station.
7. Use only factory replacement parts when replacement of parts is necessary.
8. Failure to comply with all of these warnings may result in loss of load, damage to jack, and/or failure
resulting in personal injury or property damage.

Assembly
Note: For parts identification, refer to parts list.

page 5).
2. Remove handle bolt (25, page 5).
3. Insert handle assembly into handle socket (27, page 5). Make sure handle assembly engages gear
shaft (29, page 5) by turning handle back and forth and observing movement of handle socket gear
(14, page 7).
4. Install handle bolt (25, page 5) to secure handle assembly.

Lubrication
Note: Before initial operation, lubricate the jack.
1. Handle - use #2 tube grease on release valve gears below handle and lightly grease handle at point
where it fits into socket.
2. Lifting Arm - inject #2 tube grease into grease fitting.
3. Plunger - use #2 tube grease to lubricate pump plunger.
4. Lubricate pivoting and moving parts with a 30W oil.
Lubrication Points
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.
