Troubleshooting; Raising The Jack; Lowering The Jack - Jet FLJ-45 Owner's Manual

Raising the Jack

1. Turn handle knob clockwise, until resistance is felt. Do not over tighten.
2. Place jack directly under object to be lifted. Check positioning under slight load to confirm jack or
load will not slip, and is properly centered under load.
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 knob counter-clockwise. Speed of descent is controlled by how much the release
valve is turned. Always lower the load slowly and with caution
2. Always store jack in the fully lowered position.

Troubleshooting

If jack fails to rise to its limit, or performs poorly remove oil fill plug (42), and inspect hydraulic oil level.
Fill with high quality hydraulic jack oil to the plug level. Replace oil fill plug and test jack without a load for
proper function and operation several times.
Sometimes during shipment and handling, air may be allowed into the hydraulic system, causing poor
lifting performance. Before initial operation, purge any air from the system by fully opening pump release
valve (turn handle knob counter-clockwise). Pump handle rapidly several times and close pump release
valve. If jack does not lift properly, repeat air purging process.
