GROUNDING INSTRUCTIONS
This machine must be grounded. If it should 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 a
cord having an equipment-grounding conductor and grounding plug. The
plug must be inserted into an
appropriate outlet that is properly installed and grounded in accordance
with all local codes and
ordinances.
WARNING: Improper connection of the equipment-grounding
conductors can result in a risk of electric shock. Check with
a qualified electrician or service person if you are in doubt
as to whether the outlet is properly grounded. Do not,

modify the plug provided with the machine-if it will not fit
the outlet, have a proper outlet installed.
This machine is for use on a nominal 120-volt circuit, and has a grounded
plug that looks like the plug
illustrated in sketch A in Figure 1. A temporary adapter that looks like the
adapter illustrated in sketches
B and C may be used to connect this plug to a 2-pole receptacle as show in
sketch B if a properly
grounded outlet is not available. The temporary adapter should be used
only until a qualified electrician
can install a properly grounded outlet (sketch A). The green colored rigid
ear, lug, or the like extending
from the adapter must be connected to permanent grounds such as a
properly grounded outlet box c
over. Whenever the adapter is used, it must be held in place by a metal
screw.
Note: In Canada, use of a temporary adapter is not permitted by
the Canadian Electrical Code
WARNING: Always use this machine with an AC three conductor
electrical system connected to the electrical ground.
Replace any worn, cut, or damaged cords. Replace
damaged plugs, receptacles or connector bodies.
WARNING: Do not cut, remove or break the ground terminal. Do not
try to fit a three-terminal plug into a receptacle or
connector body that does not fit the plug. If the receptacle
or connector body does not fit the plug, have a qualified
electrician make the connection.
WARNING: Do not move the machine over an electrical cord. Always
lift the cord over the machine.
WARNING: To reduce the risk of electrocution, keep all connections dry
and off the ground. Do not touch the plug with wet hands.
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prog grounding-type plugs and
3-pole cord connectors that
accept the plug from the product. Use only extension cords that are
intended for extra-hard service.
These extension cords are identified by a marking such as “S, SO, ST, or
STO”. Use only extension cords
having an electrical rating no less than the rating of the product. DO not use
damaged extension cords.
Examine the extension cords before using, and replace if damaged. Do not
damage the extension cord
and do not pull on any cord to disconnect. Keep the cord away from heat
and sharp edges. Always
disconnect the extension cord from the receptacle before disconnecting the
product from the extension
cord.
