110V Operation
The SHOP FOX
®
W1688 can also be operated at
110 volts (refer to the wiring diagram on Page
38. You will need a NEMA-style 5-20 plug and
receptacle as shown in Figure 8. The motor is
rated at 1
1
⁄2 HP and draws approximately 16
amps. Use an outlet with a 20 amp circuit break-
er or fuse. Remember other machines using the
same circuit as this machine add to the total
electrical load applied to the circuit. Add up the
amperage load ratings of all machines on the cir-
cuit. If this total amperage load exceeds the
amperage rating of the circuit breaker or fuse,
use a different circuit with a higher amperage
rating.
DO NOT modify an existing low-amperage circuit
by only replacing the circuit breaker with a
breaker rated for a higher amperage. The break-
er and the complete circuit must be replaced by
a qualified electrician.

receptacle.
We do not recommend using an extension cord
with 110V equipment. Using extension cords
with an undersized gauge or one that is too long,
generates heat in the cord that may cause fire
or circuit damage. If you must use an extension
cord, use the guidelines below and
TABLE 3 to
determine the correct cord length and gauge.
The amp rating of the motor is 16 amps while
wired for 110V and can be found on the motor-
data plate.
•Use a cord rated for Hard Service (Grade S)
•Use a cord that is 100 feet or less only
•Use a cord with a NEMA-style 5-20 plug
•Use only undamaged cords
Extension Cords
Grounding
Ground this machine! The electrical cord sup-
plied with the Model W1688 does not come with
a 110 volt plug. Use a plug with a ground pin as
shown in Figure 8. If your receptacle does not
accommodate a NEMA 5-20 plug with a ground
pin, have the receptacle replaced by a qualified
electrician or have an appropriate adapter
installed and grounded properly.
Remember, an adapter with a grounding wire
does not guarantee the machine will be ground-
ed. A ground source must always be verified in
the electrical circuit within the wall or conduit.
Any electrical outlet and cir-
cuit that you plug your
machine into must be
grounded. Serious injury
and/or fire may occur if this
warning is ignored!
