Procedure to Lower the System

1. Physically clear the entire working area of all personnel and any obstructions.
2. Attach air line.
3. Engage the elevation control valve, slowly and smoothly.
4. Open air gate valve slowly but adequately to operate system, raising the system vertically.
5. Raise the system vertically just enough to take pressure off the safety latches.
6. Once stopped, shut off air gate valve and manually release both safety latches.
7. Engage the elevation control handle slowly and smoothly to lower the system vertically.
8. Once the desired location is reached release tghe control valve slowly and smoothly.
9. If the system is lowered completely it will come to rest on the mainstops. However, if the system is to be stopped above this level you must re-engage the safety latches.
10. To reset the safety latches engage the elevation control handle slowly, open air gate valve slowly but adequately to operate the system. Raise the system just enough to engage the latches on both ends. A loud clack will be heard as each latch re-engages.
11. Slowly shut off air gate valve, and slowly release the elevation control valve.
12. Now slowly and smoothly reverse the elevation control valve to lower the system firmly onto the safety latch stops.
13. The operator MUST now make sure both stops are loaded and that the lifting system is safely at rest.

ONLY when the system is safely at rest may personnel (re)enter the working area
