Operating Tips
Lifting machinery:
1. Make sure that the jack and the machinery have been placed on a suitable surface.
2. If the machinery is fitted with castors, apply the parking brake or lock the castors.
3. To place the jack correctly, consult the instruction manual of the machinery.
4. Do not overscrew the release valve.
5. Place the operating lever and pump to lift the machinery.
6. Immediately place some stands to support the machinery. Do not work under the machinery if it
has been lifted without placing any stands. The jack is designed to lift the weight; it does not
guarantee static maintenance.
7. Slowly unscrew the release valve, to control down speed, until contact is made with the stands.
Lowering machinery
1. Do not overscrew the release valve.
2. Pump to lift the machinery, until it is pulled away from the stands.
3. Remove the stands.
4. Slowly unscrew the release valve, to control down speed, until contact is made between the
machinery and the ground.

3. Do not overscrew the release valve.
4. Pump until the maximum height of the cylinder is reached, and keep pumping 10 times, to let
trapped air out.
5. Unscrew the release valve and lower the cylinder completely.
6. Screw the release valve (do not overscrew it) and test operation; repeat the above operations, if
need be.
