• WARNING: Changes or modifications to this unit
not expressly approved by the party responsible
for compliance could void the user’s authority to
operate the equipment.
This equipment has been tested and found to com-
ply with the limits for a Class B digital device, pursu-
ant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference in a residential installation. This
equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference
will not occur in a particular installation. If this
equipment does cause harmful interference to
radio or television reception, which can be deter-
mined by turning the equipment off and on, the
user is encouraged to try to correct the interfer-
ence by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment
and receiver.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is con-
nected.
• Consult the dealer or an experienced radio/TV
technician for help.
Double insulated tools can use either a two or
three wire extension cord. As the distance from the
supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the
greater the capacity of the cord. For example, a 14
gauge cord can carry a higher current than a 16
gauge cord. When using more than one extension
cord to make up the total length, be sure each cord
contains at least the minimum wire size required.
If you are using one extension cord for more than
one tool, add the nameplate amperes and use the
sum to determine the required minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors,
be sure it is marked with the suffix “W-A” (“W”
in Canada) to indicate that it is acceptable for
outdoor use.
• Be sure your extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualified person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
• Unplug all cords during lightning storms or when
unused for long periods of time.
* Based on limiting the line voltage drop to five volts at
150% of the rated amperes.

The lightning flash with arrowhead symbol, within
an equilateral triangle, is intended to alert the user
to the presence of uninsulated "dangerous volt-
age" within the product's enclosure that may be of
sufficient magnitude to constitute a risk of electric
shock to persons.
The exclamation point within an equilateral triangle
is intended to alert the user to the presence of
important operating and maintenance (servicing)
instructions in the literature accompanying the
appliance.
CAUTION: TO REDUCE THE RISK OF ELECTRIC
SHOCK, DO NOT REMOVE COVER (OR BACK). NO
USER-SERVICABLE PARTS INSIDE. REFER SERVICI-
ING TO QUALIFIED SERVICE PERSONNEL.
