INTRODUCTION
DOUBLE INSULATION Is a concept in safety, In electrlc power tools, which eliminates the need for the
usual three wire grounded power cord and grounded
sup_)ly system. Wherever there is electric current in
the tool there are two complete sets of insulation to
protect the user. All exposed metal parts are isolated
from the internal metal motor components with protecting Insulation.
GENERAL
Your electronic router is a versatile woodworking
tool which will giv e you years of trouble-free performance. It is engineered with the professional in
mind, but its ease of operation allows the amateur to
produce work which is beautiful and precise. Your
new router has advanced electronic features which
are designed to assist you In getting the maximum
use from your router. By making "the proper selections on the front panel, your router can be adjusted
to your specific routing needs. This eliminates much
of the guess work previously needed to perform a
glven job. Both the experienced and inexperienced
router users benefit, obtaining professional like
results with fewer job errors.
The electronic feature of your router introduces the
flexibility
of adjusting the motor speed to the required job Conditions. The front panel can be set according to the approximate cutter diameter you will
be using and to the hardness of the material being
cut. Your router will then run smoothly up to the
IMPORTANT -- Servicing of a tool with double insulatlon requires extreme care and knowledge of the
system and should be performed only by a qualified
service technician. For service we suggest you
return the tool to your nearest Sears Store for repair.
Always use original factory replacement parts when
servicing.
desired speed and continue to maintain
while under various loads.
this speed
Also, the best cuts are made when the cutter is fed
through the material at the proper rate. Your electronic router has "too slow" and "too fast" Indicators that will flash if the cutter is being fed too
slow or too fast. When possible, you should make
practice cuts on a scrap piece of wood to get a
"feel" of how fast to "feed" your router.
If your router should become overloaded or jammed,
then both the "too stow'" and "too fast" indicator
lights will begin flashing. If the overload condition Is
not corrected, your router will shut off. This helps
prevent the possibility of damage to the router. To
restart, release the trigger switch to its full "off"
position, wait until the indicator lights stop flashing,
then turn your router on. WARNING:
DO NOT
OVERLOAD YOUR ROUTER REPEATEDLY. ABUSE
OF THIS NATURE WILL GREATLY REDUCE THE
LIFE OF YOUR ROUTER.

OPERATION
KNOW YOUR ELECTRONIC ROUTER
Before attempting
to usa your router, familiarize
yourself with all operating features, electronic
features,
and safety requirements.
See Figure
/.WARNING:
DO NOT ALLOW FAMILIARITY WITH
YOUR ROUTER
TO MAKE
YOU CARELESS.
REMEMBER THAT A CARELESS FRACTION OF A
SECOND IS SUFFICIENT TO INFLICT SEVERE IN.
JURY.
We suggest that you practice with the electronic
features of your router before installing a cutter and
making cuts in wood. CHECK THE FOLLOWING
BEFORE CONNECTING
YOUR ROUTER TO POWER
SUPPLY:
1. Make sure the spindle lock is in the unlocked
position.
2. Make sure the trigger is not In the "lock on" position.
3. Make sure there Is not a cutter In the collet.
Fig. 2
4, Make sure the coIlet is inside the subbase.
Next, plug your router into power supply source
and note the indicator lights on the front panel.
See Figure 2. The "soft" and "1/4 inch" indicator
lights should belit. This tells you that your router
will operate best when cutting soft wood with 1/4
Inch steel cutters.
Grasp your router firmly with both hands and turn on.
Note the smooth acceleration of your router up to
the desired speed, with little or no twisting motion in
your hands. Once your router reaches the desired
speed, the "too slow" indicator light will begin
flashing. This tells you that there is no load on your
router. If you were actually cutting with the Router
then you would know that the rate of feed is too
slow. For best cutting results, you should then Increase the rate of feed until the indicator light quits
flashing.
NOTE: The "Too Slow" indicator Is a guide for
routing in general. In some specialized cases, such
as cutting dovetails, etc., it is necessary to feed your
router at a slower rate of feed in order to maintain
proper control. In these special situations, the "Too
Slow" indicator light will continue to flash and
should not be considered to be a problem.
You should also practice making material and cutter
size selections on the front panel. Become familiar
with the fact that these selections control speed,
which Is important when changing from one type of
wood to another or from one cutter size to another.
This controlled speed eliminates rnueh of the suddan "jerk" associated with non-electronic routers,
and increases your chances of getting smooth, burn
free cuts. The next two paragraphs describe how
material and cutter size selections are made.
MATERIAL SELECTIONS
As mentioned In the introduction, the left side of the
front panel of your electronic muter allows you to
make controlled speed selections according to the
hardness of the material being cut. Each time you
press the "select"
region above the material Indicator lights, the indicator light will shift one position. See Figure 2. The first push will change the indicator light from "soft" to "medium",
a second
push will change it from "medium"
to "hard", and a
third push will change it from "hard" to "very hard."
A fourth push will return the light tothe "soft" position. NOTE: These positions cannot be changed
with the router running.
CUTTER SiZE SELECTIONS
The right side of the front panel of your electronic
router also allows you to make controlled speed'
selections according to the size of cutter you are
using. Each time you press the "select"
region
above the cutter size Indicator lights, the indicator
light will shift one position. See Figure 2. The first
push will change the indicator light from "1/4 inch"
to "3/8 inch", a second push will change It from
"3,_8 Inch" to "1/2 inch", and a third push will
change it from "1/2 Inch" to °'3/4 inch". A fourth
push will return the light to the "1/4 inch" position.
NOTE: These positions cannot be changed with the
router running.

ROUTING
See Figure 6.
For ease of operation and maintaining proper control, your router has two handles, one on each side of
the router base. After carefully making material and
cutter size selections, grasp your router and hold It
firmly with both hands as shown In Fig. 6. Turn
router on and let motor build to its full speed, then
gradually feed cutter into workpiece. Remain alert
and watch what you are doing. DO NOT operate
router when fatigued.
SPEED SELECTIONS
In general, as you move the material and cutter size
Indicators to lower positions, the router will run at
slower speeds. The slowest speed at which your
router will run is when the material indicator setting
Is at the "hard" position and the cutter size setting is
at the "3/4 inch" position. The fastest speed at
which your router will run is when the material indicator setting is at the "soft" position and the cutter size setting Is at the "1/4 inch" position.
A change from the "hard" to "very hard" material indicator position will cause an increase in the speed
of your router. This is because carbide cutters,
which cut at higher speeds than steel cutters,
should be used when cutting very hard materials.
See Helpful Hints, page 11.
RATE-OF-FEED
IMPORTANT:
In addition to selecting the proper
speed for your router, the "secret"
to professional
routing and edge shaping lies In making a careful
set-up for the cut to be made and in selecting the
proper rate of feed.
FORCE FEEDING
Clean, smooth routing and edge shaping can be
done only when the bit Is revolving at or near its proper speed and is taking very small bites to produce
tiny, cleanly severed chips. If the router is forced to
move forward too fast, the "too fast" indicator light
will begin flashing. Th_s tells you that the RPM of the
bit Is slower than normal in relation to its forward
movement - and that the bit must take bigger bites
as It revolves. "Bigger bites" means bigger chips,
and a rougher finish. Bigger chips also require more
TOO FAST
TOO SLOW

Fig. 6
power - and the router motor can become overloaded so that it slows down and possibly even shuts
itself off. Under extreme forcefeeding conditions the
relative RPM of the bit can become so slow - and the
bites It has to take so large - that chips will be partially knocked off (rather than fully cut off), with
resulting, splintering and gouging of the workpiece.
See Fig. 7.
YOU SHOULD ALWAYS TRY FOR A MEDIUM RATEOF-FEED, MAKING SURE THE "TOO SLOW" INDICATOR LIGHT HAS GONE OUT AND THE "TOO
FAST" INDICATOR DOES NOT COME ON.
Your Craftsman Electronic Router is an extremely
high-speed tool (up to 25,000 rpm no-load speed),
and will make clean, smooth cuts if allowed to run
freely without the overload of a forced (too fast) feed.
What constitutes
"force-feeding"
depends upon
three things: Bit size, depth-of-cut,
and workpiece
characteristics. The larger the bit and/or the deeper
the cut, the more slowly the router can be moved forward. And, if the wood is very hard, knotty, gummy or
damp, the operation must be slowed still more.
TOO SLOW FEEDING
It Is also possible to spoil a cut by moving the router
forward too slowly. When it is advanced into the
work too slowly a revolving bit doesn't dig into new"
wood fast enough to take a bite; instead, it simply
scrapes away sawdust-like particles. Scraping produces heat, which can glaze or burn and mar the cut
-- in extreme cases, can even overheat the bit so as
to destroy its hardness.
In add(lion, It is more difficult to control a router
when the bit is scraping Instead of cutting. With
practically no load on the motor the bit will be revolving close to top rpm forths selected speed, and will
have a much greater than normal tendency to
bounce off the sides of the cut (especially, if the
wood has a pronounced grain with hard and soft
areas). As a result, the cut produced may have rlppled, instead of straight, sides. See figure 7.
You can detect "too-slow
feeding" by the flashing
light, the no-load sound of the motor, or by feeling
the "wiggle"
of the bit in the cut.
P_e7
OPERATION
PROPER FEEDING
DIRECTION
The right feed is neither too fast nor too slow. It is
the rate at which the bit is being advanced firmly and
surely to produce uniform chips -- without hogging
Into the wood to make large individual chips or, on
the other hand, to create only sawdust. If you are
making a small diameter, shallow groove in soft, dry
wood, the proper feed may be about as fast as you
can travel your router along your guide line. If the bit
_s a large one, the cut is deep, and/or the wood is
hard to cut, the proper feed may be a very slow one.
Then,. again, a cross-grain cut may require a slower
pace than an identical with grain cut in the same
workplace.
The router motor and bit revolve in a clockwise diraction. This gives the tool a slight tendency to twist
(in your hands) in a counterclockwise direction.

DEPTH OF CUT
As previously mentiofled, the depth of cut is important because it effects the rate of feed which, In turn,
affects the quality of a cut (and, also, the possibility
of damage to your router motor and bit). A deep cut
requires a slower feed than a shallow one. A too
deep cut will cause you to slow the feed so much
that the bit will begin scraping instead of cutting.
Making a d'eep cut is never advisable. The smaller
bits -- especially those only 1/16 inch in diameter
-- are easily broken off when subjected to too much
side thrust. A large enough bit may not be broken off,
but if the cut is too deep a rough cut will result
and it may be very difficult
to guide the bit as
desired. For these reasons, we recommend that you
do not exceed 1/8 inch depth of cut in a single pass,
regardless of the bit size or the softness or condition
of the workpiece. See Fig. 8.
OF FEED AND THRUST
Because of the extremely high speed of bit rotation
during a "proper feeding" operation, there is very little kickback to contend with under normal conditions. However, should the bit strike s knot, hard
grain, etc. that would affect the normal progress of
the cutting action, there will be a slight kickback -sufficient to spoil the trueness of your cut if you are
not prepared. Such a kickback is always in the direction opposite to the direction of bit rotation.
To guard against such a kickback, plan your set-up
and direction of feed so that you will always be
thrusting the tool -- to hold it against whatever you
are using to guide the cut -- Jn the same direction
that the leading edge of the bit is moving. In short,
the thrust should be in a direction that keeps the
sharp edges of the blt continuously biting straight
into new (uncut) wood.
ROUTING
See Figure 10.
Whenever you are routing a groove, your tool travel
should be In a direction that places whatever guide
you are using at the right-hand side. When the guide
is positioned as shown in the first part of Fig. 10, tool
travel should be left to right and counterclockwise
around curves. When the guide is positioned as
shown in the second part of Fig. 10, tool travel
should be right to left and clockwise around curves.
If there is a choice, the first set-up is generally the
easiest to use. In either case, the sideways thrust
you see is against the guide.

To make deeper cuts it is therefore necessary to
make as many successive passes as required, lowering the bit 1/8 inch for each new pass. In order to
save time, do all the cutting necessary at one depth
setting, before lowering the bit for the next pass.
This will also assure a uniform depth when the final
pass is completed. See Fig. 9.

OPERATION
Whenever you are shaping an edge, the feed should
always be clockwise when working on an outside
(convex) edge; but should be counterclockwise
when working on an inside (concave) edge. See Fig.
11. The reason for this is that, when traveling the tool
as instructed, the bit will have a "chopping
action"
but will have a "gouging a,ction" If you reverse the
travel direction. "Chopping
is much preferable to
"gouging"
as there Is less danger of ripping, out
chips by tearing the wood grain.
