6) is available for connecting plugs to a two pole outlet if it is
properly grounded.
•Do not use a 3-prong to 2-prong grounding adapter unless per-
mitted by local and national codes and ordinances.
(A 3-prong to 2-prong grounding adapter is not permitted in
Canada.) Where permitted, the rigid green tab or terminal on
the side of the adapter must be securely connected to a perma-
nent electrical ground such as a properly grounded water pipe,
a properly grounded outlet box or a properly grounded wire
system.
•Many cover plate screws,water pipes and outlet boxes are not
properly grounded.To ensure proper ground, grounding means
must be tested by a qualified electrician.
EXTENSION CORDS
•The use of any extension cord will cause some drop in voltage
and loss of power.
•Wires of the extension cord must be of sufficient size to carry
the current and maintain adequate voltage.
•Running the unit on voltages which are not within ±10% of the
specified voltage may cause overheating and motor burn-out.
