Double Insulation
Your unit is DOUBLE INSU¬
LATED 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 tool is
equipped with a two-prong plug
which permits you to use extension
cords without concern for maintain¬
ing 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 RE¬
PLACEMENT PARTS. Repair or
replace damaged cords.
Motor
Your ELU tool is powered by a
quality built motor. Be sure your
power supply agrees with the
nameplate marking.
Volts 50/60 Hz or MAC 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 tools 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.
Special Instructions
For Electronic
Routers Cat. #3338
& 3338-2
Your router incorporates a
state of the art electronic motor
control. The control system
governs the motor to give you
ramp start-up, smooth cutting,
and constant speed. These
unique capabilities give you a
router which is responsive to
your needs.
The electronic motor control
system has two basic features.
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 acceler¬
ates the motor up to speed
smoothly, without jerking,
and allows you to maintain
easier control of the router
during the start up period.
B. Constant speed cutting - as
you load the router, the
selected cutting speed does
not slow down during normal
use. The electronic control
governs the motor and gives
you a consistent finish to
your work. Only under very
heavy loading will the speed
of the unit fall below the gov¬
erned speed.
To set the router speed (from
8,000 rpm to 20,000 rpm) rotate
the speed control wheel shown
in the large figure on page 6.
The higher the number the
higher the speed.
There are five marked speed
stages on your router.
The approximate speeds at
these settings are:
Speed Stage 1 - 8,000 rpm
Speed Stage 2 - 12,000 rpm
Speed Stage 3 - 16,000 rpm
Speed Stage 4- 18,000 rpm
Speed Stage 5 - 20,000 rpm
Refer to the chart on the next
page to match proper speed to
the material being cut.
