-4- G1140 Edge Sander
The Model G1140 will draw approximately 8
amps at 220V and 16 amps at 110V. Circuit pro-
tection when operating at 220V should be on a
breaker rated at 15 amps or a fuse rated at 20
amps. At 110V a 20 amp slow-blow fuse or
breaker should be used. Fusing at amperage rat-
ings higher than these will not adequately protect
the motor from high heat caused by overloading.
You are cautioned that equipment returned to us
for service that shows evidence of being over-
fused will be repaired or replaced totally at the
customer’s expense, regardless of the present
warranty status.
Be aware that other machines operating on the
same circuit simultaneously will also add load
which can cause the circuit protection system to
trip.
SECTION 2: CIRCUIT REQUIREMENTS
220V/110V
Operation
The Model G1140 has a dual-voltage 1
1
⁄2 HP,
1720 RPM motor which has been pre-wired for
use in a 220V single phase circuit. The cord set
enclosed does not have a plug as the style of
plug you require will depend upon the type of
service you currently have or plan to install. If you
will be installing a new receptacle and plug, we
recommend either of the styles shown in Figure
1. Note that you have the choice between simple
plug-in and twist-lock plug styles.
Should you prefer to utilize the 110V capability, a
wiring diagram is provided near the back of this
manual showing the wiring changes needed.
Operating at 110V will also require installing a
grounded plug.

Grounding
This equipment must be grounded. Verify
that any existing electrical outlet and circuit you
intend to plug into is actually grounded. If it is
not, it will be necessary to run a separate 12
A.W.G. copper grounding wire from the outlet
to a known ground. Under no circumstances
should the grounding pin from any three-
pronged plug be removed. Serious injury may
occur.
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric
shock. This tool is equipped with an electric cord
having an equipment-grounding conductor which
must be properly connected to a grounding plug.
The plug must be inserted into a matching outlet
that is properly installed and grounded in accor-
dance with all local codes and ordinances.
Improper connections of the electrical-grounding
conductor can result in risk of electric shock. The
conductor with green or green and yellow striped
insulation is the electrical-grounding conductor. If
repair or replacement of the electric cord or plug
is necessary, do not connect the equipment
grounding conductor to a live terminal.
