G1071 Oscillating Spindle Sander
III. ELECTRICAL SERVICE REQUIREMENTS
C. GENERAL INFORMATION
If converting to 220V, it will be necessary to
connect a plug that matches your 220V recep-
tacle. If you will be installing a new receptacle
and plug, we recommend either of the follow-
ing styles.
EXTENSION CORDS: If used, extension
cords must be rated hard service – grade S –
or better. Conductor size must be 12 AWG for
cords up to 50 feet in length. Your extension
cord must also contain a ground wire and plug
pin. Repair or replace extension cords if they
become damaged.
A. CIRCUIT LOADING
The G1071 motor will safely draw about 14
amps at 110V (7A @ 220V) under load. If you
operate the sander on any circuit that is
already close to its capacity, it might blow a
fuse or trip a circuit breaker. However, if an
unusual load does not exist, and power fail-
ure still occurs, have the circuit inspected by
a qualified electrician.
CIRCUIT BREAKERS/FUSES: A 15 amp cir-
cuit breaker or fuse should be used for a
110V undedicated circuit. A 10 amp circuit
breaker or fuse should be used for a 220V
undedicated circuit. The general rule is to use
the lightest breaker or fuse that will hold
under regular loads. Circuit breakers or fuses
that are rated higher may not adequately pro-
tect the motor.
B. GROUNDING
This machine must be electrically ground-
ed. We have furnished the sander with a cord
suitable for use with a grounded, domestic
110V circuit.

In this section we have covered some basic
electrical requirements for the safe opera-
tion of your sander. Keep in mind that these
requirements are not necessarily compre-
hensive. Further, you must be sure that your
particular electrical configuration complies
with local and state codes. The best way to
ensure compliance is to check with your
local municipality or licensed electrician.
Please verify that any circuit you intend to
use is actually grounded. If the circuit is not
grounded, it will be necessary to run a sep-
arate 12 AWG copper grounding wire from
the machine frame to a grounding terminal
in your electric service panel.
If you are not sure about wiring your
sander, don’t take chances: consult the
service department or an electrician.
The Model G1071 has a 1 HP motor that
operates at 110V/220V. It has been pre-wired
for 110V, single phase operation. Please con-
sult the wiring diagram for information about
conversion to 220V.
