-6- G3183 Hollow Chisel Mortiser
Circuit Requirements
The motor supplied with the Model G3183 is a
110V single-voltage motor, prewired for 110V.
Under normal use, the motor draws approximate-
ly 6 amps @ 110V. We recommend using a 15
amp circuit breaker or a 15 amp slow blow fuse
for 110V operation. This should be satisfactory
for normal use, while preventing motor damage
from high heat caused by overload. If frequent
circuit failures occur when using the Hollow
Chisel Mortiser, contact our service department
or your local electrical contractor. The Hollow
Chisel Mortiser cannot be wired for 220V opera-
tion.
This equipment must be grounded. Please
ensure that the Hollow Chisel Mortiser is continu-
ously grounded from the motor to the machine
frame and then to a known ground. 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.
Extension Cords: If used, extension cords must
be rated Hard Service (grade S) or better.
Conductor size must be 14 A.W.G. for cords up to
50 feet in length. Your extension cord must also
contain a ground wire and plug pin. Always repair
or replace extension cords if they become dam-
aged.
CAUTION: 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 electri-
cian.
