system) from where it enters the foot switch to the equipment it's wired up to for wear, loose strain relief connections
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.

WARNING
USE OF FOOT CONTROLS ON MACHINERY LACKING EFFECTIVE POINT
OF OPERATION SAFEGUARDS CAN CAUSE SERIOUS INJURY TO THE
OPERATOR.
Foot controls should only be used where “Point of Operation” and “Pinch
Point” guarding devices have been properly installed and are utilized so that it
is IMPOSSIBLE for the operator’s hands or fingers to remain within the point
of operation during the machine cycle.
IT IS THE RESPONSIBILITY OF THE USER to determine the suitability of a
foot control for the user’s intended use and to determine that the foot control
chosen by the user and wiring up and installation of same will comply with all
Federal, State and Local safety and health regulations and codes.
Due to the unlimited variety of business equipment, instruments, machines
and vehicles on which our foot switches are used, the thousands of standards,
and customers’ varying interpretations of the standards covering these
applications, it is impossible for LINEMASTER personnel to be experts on
standards and requirements for all these products. We offer over 150 stock
foot switch models and guards plus a large variety of specials which are made
to customer specifications. We can advise you what is available in our foot
switch line and you can examine models to see what meets your needs. We
believe our customers’ engineering departments should be the qualified
experts in their own product field and know what specifications or details they
may require in a foot switch for their equipment. If one of our stock models
meets their needs, they can specify it, or possibly ask for a modification of a
stock model if that is required.
SHOULD YOU HAVE ANY QUESTIONS OR IF ANY OF THE ABOVE
WARNING IS UNCLEAR, PLEASE CALL LINEMASTER SWITCH
