one heavy enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage resulting in
loss of power and overheating. The following table shows the
correct size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gage. The
smaller the gage number, the heavier the cord.

• OUTDOOR USE EXTENSION CORDS. When tool is used
outdoors, use only extension cords intended for use outdoors
and so marked.
• STAY ALERT. Watch what you are doing. Use common sense.
Do not operate tool when you are tired.
• CHECK DAMAGED PARTS. Before further use of the tool, a
guard or other part that is damaged should be carefully checked
to determine that it will operate properly and perform its
intended function. Check for alignment of moving parts, binding
of moving parts, breakage of parts, mounting, and any other
conditions that may affect its operation. A guard or other part
that is damaged should be properly repaired or replaced by a
D WA L T certified service center unless otherwise indicated
E
elsewhere in this instruction manual. Have defective switches
replaced by a D WA L T certified service center. Do not use tool
E
if switch does not turn it on and off.
• DO NOT OPERATE portable electric tools near flammable
liquids or in gaseous or explosive atmospheres. Motors in these
tools normally spark, and the sparks might ignite fumes.

Double Insulation

DOUBLE-INSULATED tools are constructed throughout with TWO
separate "layers" of electrical insulation between you and the tool's
electrical system.
Tools built with this insulation system are not intended to be
grounded. As a result, your tool is equipped with a two-prong plug
which permits you to use extension cords without concern for
maintaining a ground connection.
N O T E : DOUBLE INSULATION does not take the place of normal
safety precautions when operating this tool. The insulation system is
for added protection against injury resulting from a possible
electrical insulation failure within the tool.
CAUTION: When servicing all tools, USE ONLY IDENTICAL

Polarized Plugs

Polarized plugs (one blade is wider than the other) are used on
equipment to reduce the risk of electric shock. When provided,
this plug will fit into a polarized outlet only one way. If the plug
does not fit fully into the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician to install the proper outlet. Do not
change the plug in any way. REPLACEMENT PARTS. Repair or
replace damaged cords.

your power supply agrees with the nameplate marking.
Volts 50/60 Hz or "AC only" means your tool must be operated only
with alternating current and n e v e r with direct current. Volts DC-
60Hz or AC/DC means your tool may be operated with either
alternating or direct current.
