READ ALL INSTRUCTIONS BEFORE USING THIS APPLIANCE
WHEN USING AN ELECTRICAL APPLIANCE, BASIC PRECAUTIONS SHOULD ALWAYS
BE FOLLOWED, INCLUDING THE FOLLOWING:
WARNING – TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY
1. Do not leave appliance when plugged in. Unplug from outlet when not in use and
before servicing.
2. Do not use outdoors or on wet surfaces.
3. Do not allow to be used as a toy. Close attention is necessary when used by or near children.
4. Use only as described in this manual. Use only manufacturer’s recommended attachments.
5. Inspect cord for damage before each use. Do not use with damaged cord or plug. If appliance
is not working as it should, has been dropped, damaged, left outdoors, or dropped into water,
return it to a service center.
6. Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull cord
around sharp edges or corners. Do not run appliance over cord. Keep cord away from
heated surfaces.
7. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
8. Do not handle plug or appliance with wet hands.
9. Do not put any object into openings. Do not use with any opening blocked; keep free of dust,

20. Do not use for picking up health endangering dust such as asbestos.
21. This is a commercial appliance, not intended for household use.
IMPORTANT SAFETY INSTRUCTIONS 2

This appliance 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 appliance
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 conductor can result in the 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 appliance.
If it will not fit the outlet, have a proper outlet installed by a qualified electrician.
This appliance is for use on a nominal 120 volt circuit, and has a grounded plug that looks
like the plug illustrated in sketch A. 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 shown in sketch B
if a properly grounded outlet is not available. The temporary adapter should be used only until a
properly grounded outlet (sketch A) can be installed by a qualified electrician. The green colored
rigid ear, lug, or the like extending from the adapter must be connected to a permanent ground
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.
