and the like. DO NOT OPERATE the foot switch if any of the above is observed or if the nameplate or warning label
has been obscured or removed.
It is IMPERATIVE that inspection authorities and users exercise more than ordinary care with regard to installation and
maintenance and that this information sheet be made available to the end user, operators, maintenance personnel and
to others responsible for proper installation and safe operation of this foot switch.
ADDITIONAL COPIES of this information sheet and warning labels are available upon request.
