Windwright
Recommended Procedure
Most instruments can be tested while fully assembled; the following instructions assume this setup. Individual instrument components may also be tested separately if desired.
Before connecting the Windwright to an instrument:
- Set all gauges to their starting positions.
- Select the best-fitting stop for the bell section.
- Blow air into the instrument to confirm it is reasonably well sealed.
- Adjust the rubber stop at the end if necessary.
- Install the appropriate adapter onto the Windwright hose and insert it into the instrument receiver.
Important:
Always begin with Control C fully off (turned completely to the right) to ensure the dial is at its starting rotation. If dial will not move make sure red collar is pulled towards you.
