1. You must be trained to operate this machine. This machine is to be operated for its intended use only.
2. Do not operate this machine unless it is completely assembled.
3. Always use a three-wire electrical system connected to the electrical ground. For maximum protection against
electricalshock,usea circuit that is protected by agroundfaultcircuit interrupter. Consultyour electrical contrac-
tor.
4. To prevent electric shock, always remove the electrical plug from the electrical outlet before doing any repairs or
maintenanceand when leaving the machineunattended.
5. To prevent electric shock,keepthemachinesurfacedry. Donot subject to rain. Storethe machine in a dry building
area. Clean the machine with a dry cloth only.

orcorners. Keep cord away from heated surfaces.
9. Do not use withdamagedcordorplug. Ifthe machine is not working asitshould,hasbeendropped, damaged, left
outdoors,or dropped into water, returnit to a service center.
This machine must be grounded. If it should malfunction or break
down, grounding provides a path of least resistance for electric
currenttoreducethe riskof electricshock. This machineis equipped
with a cord having an equipment-grounding conductor and ground-
ing 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
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.
This machine is for use on a nominal 120-volt circuit, and has a
grounded plug that looks like the plug illustrated in figure A. A
temporary adapter that looks like the adapter illustrated in figures B
and C may be used to connect this plug to a 2-pole receptacle as
shown in figure B if a properly grounded outlet is not available.
The temporary adapter should be used only until a properly
grounded outlet (figure A) can be installed by a qualified electri-
cian. The green colored rigid ear, lug, or the like extending from the
adapter must be connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the adapter is
used, it must be held in place by a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted
by the Canadian Electrical Code
EXTENSIONCORDS
Use only three-wire 12/3 or larger gauge approved extension
cords that have three-prong grounding type plugs and three-pole
receptacles that accept the appliance’s plug. Replace or repair
any damaged cords or plugs.
When servicing, refer to authorized person only. Use only identi-
cal replacement parts.
