GROUNDING
iNSTRUCTiONS
This machine must be grounded while in use to protect the operator from electric shock.
1.
All grounded,
cord-connected
machines:
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 machine is equipped with an electric cord having an equipment-grounding
conductor
and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection
of the equipment-grounding
conduc-tor
can result in risk of electric shock. The conductor
with insulation having an outer surface that is green with or without yellow stripes is the equipment-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.
Check
with a qualified
electrician
or service
personnel
if the grounding
instructions are not completely
understood, or if in doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor
receptacles that
accept the machine's plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.
2.
Grounded,
cord-connected
machines
intended for use on a supply circuit
having
a nominal
rating
less
than 150 volts:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the
machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks
like the adapter illustrated in Fig. B, may be used to connect this plug to a matching 2-conductor
receptacle as
shown in Fig. B if a properly grounded outlet is not available. The temporary
adapter should be used only until
a properly grounded outlet can be installed by a qualified electrician.
The green-colored
rigid ear, lug, and the
like, extending from the adapter must be connected
to a permanent ground such as a properly grounded outlet
box. Whenever the adapter is used, it must be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
In all cases, make certain that the receptacle
in question is properly grounded.
If you are not sure,
have a qualified electrician
check the receptacle.

EXTENSION
CORDS
Use proper extension
cords. Make sure
your extension cord is in good condition
and is a 3=
wire extension cord which has a 3=prong grounding
type plug and matching receptacle
which will accept
the machine's
plug. When using an extension cord,
be sure to use one heavy enough to carry the current
of the machine.
An undersized
cord will cause a drop
in line voltage,
resulting
in loss of power and over=
heating. Fig. D=I or D=2, shows the correct gauge to
use depending
on the cord length, if in doubt,
use
the next heavier gauge. The smaller the gauge num-
ber, the heavier the cord.
