where the ground wire is attached to an earth ground. The circuit should be protected by a circuit breaker or time delay
fuse. NOTE: Time delay fuses should be marked “D” in Canada and “T” in the US. If an extension cord is used, use
only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle which will accept the
machine’s plug. Before connecting the machine to the power line, make sure the switch (s) is in the “OFF” position and
be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should
make good contact. Running on low voltage will damage the machine.

If any of the above conditions cannot be met, or if operation of the electric motor repeatedly causes
interruption of the power, it may be necessary to operate it from a 20 amp circuit. It is not necessary to
change the cord set.

GROUNDING INSTRUCTIONS
SHOCK HAZARD. 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 conductor
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 instruction 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.
