Type AV 19-3
Vibrator Cleaning Tool Assembly:
The primary use of this unit is intended for the salvaging of fine wire electrode type aircraft spark plugs, which have
previously been cleaned and found to be unsatisfactory for further use because of heavy lead compound deposits
remaining in the firing end cavity.
1. Securely mount unit onto a conveniently located work bench, with available 110-120 volt, 60 cycle, AC power
2. Provide an exhaust duct or dust collector means under vibrator tool adapter head, in such a manner, so as when
salvaging operations are being performed, all lead compound deposit particles and dusting are positively carried
away from operation. (Continued exposure to lead compound dust should be avoided because of toxic effects).
3. Install two-pronged bayonet type cleaning tool into vibrator tool adapter head and secure with retaining flat head
