Caution: Wilton sanders are available in a wide vari-
ety of electrical configurations to meet the needs of the
purchaser with respect to power available and compliance
with electrical codes. Each machine is tested at the factory
for operation before shipment and the power cord is tagged
with the power requirements for the machine, as shipped.
HOWEVER, before attempting any electrical hookup, you
should be certain:
1. The electrical characteristics of the service branch match
the requirements of the motor.
2. The service branch is equipped with wires of the re-
quired gauge or size.
3. The branch circuit intended for the machine is protected
with a time delay fuse or circuit breaker with a rated amper-
age just slightly greater than the full load current of the
motor.
