H4380 Buffer -5-
110V Operation
SECTION 2: CIRCUIT REQUIREMENTS
If you find it necessary to use an extension cord
with the Model H4380, make sure the cord is
rated Hard Service (grade S) or better. Refer to
the chart in the standard safety instructions to
determine the minimum gauge for the extension
cord. The extension cord must also contain a
ground wire and plug pin. Always repair or replace
extension cords when they become worn or dam-
aged.
Extension Cords
Grounding
This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug into is actually
grounded. Under no cir-
cumstances should the
grounding pin from any
three-pronged plug be
removed. Serious injury
may occur.
In the event of an electrical short, grounding
reduces the risk of electric shock by providing
electric current a path of least resistance. This
tool is equipped with a power cord having an
equipment-grounding conductor. See Figure 1B.
The outlet must be properly installed and ground-
ed in accordance with all local codes and ordi-
nances.
The Model H4380 is wired for 110V. The
1
⁄2 H.P.
motor will safely draw 3.5 amps at 110V. If you
operate this machine 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 a power failure still occurs, contact a
qualified electrician or our service department.
A 10 amp circuit should be used with this buffer.
Always check to see if your current wires are
capable of handling a 10 amp load. If you are
unsure, consult the advice of a qualified electri-
cian.
