2. Subtract tool amp rating from building
circuit's amp rating.
3. Set dial to the difference.
Notes:
• The building's circuit breaker can trip if the
combination of power tool amp rating and
the dial setting exceed the building circuit's
or
toxic
amp rating.
• The dial should be set at 11 amps unless
the building circuit's amp rating minus the
power tool amp rating setting is less than 11
amps.
• If full vacuum cleaner power is needed with
a power tool that draws high amps, it may
be necessary to plug the power tool into a
