SAFETY WARNINGS

• To reduce the risk of electrical shock, this unit

has a polarized plug (one blade is wider than
the other) and will require the use of a
polarized extension cord. This unit plug will fit
into a polarized extension cord only one way. 
If the plug does not fit fully into the extension
cord, reverse the plug. If the plug still does not
fit, obtain a correct polarized extension cord. 
A polarized extension cord will require the use
of a polarized wall outlet. This plug will fit into 
a polarized wall outlet only one way. If the plug
does not fit fully into the wall outlet, reverse 
the plug. If the plug still does not fit, contact a
qualified electrician to install the proper wall
outlet. Do not change the unit plug, extension
cord receptacle, or extension cord plug in any
way.

• Ground Fault Circuit Interrupter (GFCI)

protection should be provided on the
circuit(s) or outlet(s) to be used for this unit.
Receptacles are available having built-in
GFCI protection and may be used for this
measure of safety.

ELECTRICAL SAFETY WARNINGS

• This tool is double-insulated. Use only identical

replacement parts when servicing. Repair or
replace damaged cords.

WARNING

: To reduce the risk of electrical

shock, use only extension cords approved for
outdoor use, such as an extension cord of
cord type SW-A, SOW-A, STW-A, STOW-A,
SJW-A, SJOW-A, SJTW-W or SJTOW-A. A 2-
wire extension cord (an extension cord without
a ground) may be used because the tool is
double insulated. However, a 3-wire extension
cord (an extension cord with a ground) that
uses a NEMA type connector (parallel blade, 
U ground) may also be used. Extension cords
are available from your local retailer. Use only
round-jacketed extension cords approved for
outdoor use.
