GROUNDING INSTRUCTIONS
This machine must be grounded. If it should malfunction or break down, 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 plugged into an appropriate outlet that is properly installed
and grounded in accordance with all local codes and ordinances.
DANGER - Improper connection of the equipment-grounding conductor 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 by a qualified
electrician.
Follow grounding sequence of assembly as shown to ground machine and ensure safety to operator.
FAILURE TO DO SO MAY CAUSE ELECTROCUTION due to improper connection of ground.
Check nameplate on machine to be sure voltage and cycle stated on nameplate is the same as voltage and cycle of
electrical outlet. DO NOT attempt to plug a 115 volt machine into a 240 volt outlet or a 240 volt machine into a 115 volt
outlet.
The grounding blade on the plug must remain intact if the machine is to be properly grounded when plugged in and
operated. An ungrounded machine can cause shock to the operator. See Figure A.
If connecting to an outlet that accepts only two blades use an adapter as in Figure B. NEVER REMOVE THE
GROUNDING BLADE.
If it is necessary to use the adapter shown in Figure B, the machine is only properly grounded if the adapter’s green
colored clip is tied under a metal screw that holds electrical outlet cover to the wall.
Figure C. Machine used on 240 volt may or may not have the grounding (earthed) plug attached to the cord. For
U.S.A. 240 volt 60 HZ, the plug is already supplied with cord. For use outside the U.S.A., it may be up to the
purchaser to have a proper grounding (earthed) plug attached.
When grounding blade on plug is broken, it is preferable to replace the whole cord.
Replacement cords must be U.L. Listed/CSA approved and be of the identical electrical specifications as the original
equipment cord.
If you choose to replace 3-wire plug for 115 Volt use only U.L. Listed/CSA approved plug with rating of 125 Volt 15
amps (for 240 Volt use a 3-wire plug with rating consistent with voltage and amps required). Be sure that the green
wire of the cord is connected to the green screw, and the black wire to gold screw of the replacement plug.
ALWAYS remember when replacing plug, that if the grounding wire (green) is connected to a live terminal at the
machine or plug, the machine will become electrically charged and will result in electrical shock or electrocution.
Always use a properly grounded 3-wire extension cord which has male and female plugs. Use only 14-3 ST or SO
type extension cord for a total cord length up to 100 feet.
DANGER:DO NOT ATTEMPT MAINTENANCE OR REPAIRS BEFORE
DISCONNECTING CORD FROM ELECTRICAL POWER SOURCE. READ
ALL INSTRUCTIONS AND FOLLOW ALL ILLUSTRATIONS CAREFULLY.
NOTE: IN CANADA, THE USE OF A TEMPORARY ADAPTOR IS NOT PERMITTED BY CANADIAN ELECTRICAL CODE.
