Black & Decker ELU 3303 - Manual (Page 4)

Double Insulation
Your unit is DOUBLE-
INSULATED to give you added
safety. This means that it is
constructed throughout with
TWO
separate "layers” of electrical
insulation or one
DOUBLE thickness
of 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 unit is
equipped with a two-prong plug which
permits you to use extension cords
without concern for maintaining a
ground connection.
NOTE: 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
REPLACEMENT PARTS. Repair or
replace damaged cords.
Motor
Your ELU tool is powered by an
ELU-built motor. Be sure 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 never
with direct current.
Voltage decrease of more than
10% will cause loss of power and
overheating. All ELU toos are factory
tested; if this tool does not operate,
check the power supply.
Extension Cords
Double insulated tools have 2 wire cords, and can be used with 2 wire or 3
wire extension cords. Only round jacketed extension cords should be used, and
we recommend that they be listed by Underwriters Laboratories (U.L.). If the
extension will be used outside, the cord must be suitable for outdoor use. Any
cord marked as outdoor can also be used for indoor work. The letters "WA” on
the cord jacket indicate that the cord is suitable for outdoor use.
An extension cord must have adequate wire size (AWG or American Wire
Gauge) for safety, and to prevent loss of power and overheating. The smaller
the gauge number of the wire, the greater the capacity of the cable, that is 16
gauge has more capacity than 18 gauge. When using more than one extension
to make up the total length, be sure each individual extension contains at least
the minimum wire size.
To determine the minimum wire size required, refer to the chart below.

Before using an extension cord, inspect it for loose or exposed wires,
damaged insulation, and defective fittings. Make any needed repairs or replace
the cord if necessary.

Instructions For
Electronic Router
Cat. #3304
You have just purchased a
portable router which incorporates a
state of the art electronic motor
control. The control system governs
the motor to give you easy start-up,
smooth cutting, and higher power
output. These unique capabilities give
you a router which is responsive to
your needs.
The electronic motor control
system has two basic features (Fig. 1 ).
A. Ramp start - when you turn on the
router, you will notice that it does
not have the jerk from the rapid
acceleration of the motor. This
router has a starting circuit which
accelerates the motor up to speed
smoothly, without jerking, and
allows you to maintain easier
control of the router during the
start-up period.
