INTRODUCTION
DOUBLE INSULATION Is a concept in safety, In elec-
trlc 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 pro-
tecting Insulation.
IMPORTANT -- Servicing of a tool with double in-
sulatlon 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.
GENERAL
Your electronic router is a versatile woodworking
tool which will giveyou years of trouble-free perfor-
mance. 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 selec-
tions 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 re-
quired job Conditions. The front panel can be set ac-
cording 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
desired speed and continue to maintain this speed
while under various loads.
Also, the best cuts are made when the cutter is fed
through the material at the proper rate. Your elec-
tronic router has "too slow" and "too fast" In-
dicators 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
WARNING: YOUR ROUTER SHOULD NEVER BE PLUGGED IN WHEN YOU ARE._P_SEMBLING PARTS OR
MAKING ADJUSTMENTS. FAILURE TO DO SO COULD RESULT IN ACCIDENTAL STARTING OF YOUR
ROUTER RESULTING IN POSSIBLE SERIOUS INJURY. ALWAYS WEAR SAFF_TY :GLASSES OR
EYESHIELDS BEFORE BEGINNING POWER TOOL OPERATION.
If any parts are missing do not operate your Router until the missing parts are replaced,See Figure 1.
CHIP SHIELD
A clear plastic chip shield is installed on the front of
your router for protection against flying dust and
chips. The chip shield is designed to fit the front
opening of the router base as shown in figure 1. If
necessary to remove, squeeze the tabs on each end
and pull outward. To replace, squeeze the tabs at
each end, fit Into the opening, then release. DO NOT
USE ROUTER WITHOUT CHIP SHIELD PROPERLY
IN PLACE.
SWITCH
The switch of your electronic router is equipped with
a"lock on" feature which is convenient when
operating for extended periods of time. To lock on,
depress the trigger and engage the lock button
located on the side of the handle. To release the
lock, depress the trigger and release it. BE SURE
TOOL IS NOT IN THE "LOCK ON" POBITION
BEFORE CONNECTING TO POWER SUPPLY
SOURCE.
NOTE: If you forget to unlock the tdgger, the "soft"
and "1/4 Inch" Indicator lights will begin flashing
the next time you plug your router into a power
supply source. These flashing lights serve as a
reminder that your trigger is In the "lock on" posi-
tion and that your router will not start until the trig-
ger is relased. The best precaution is to UNLOCK the
trigger after each use.

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" posi-
tion.
3. Make sure there Is not a cutter In the collet.
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 In-
crease the rate of feed until the indicator light quits
flashing.
Fig. 2
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 In-
dicator lights, the indicator light will shift one posi-
tion. See Figure 2. The first push will change the in-
dicator 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" posi-
tion. NOTE: These positions cannot be changed
with the router running.
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 aslower 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 sud-
dan "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.
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.

INSTALLING/REMOVING CUTIERS
Disconnect router from power supply.
1. A spindle lock is located on the top of motor
housing. See Figure 5. To activate lock, push
spindle lock back and slide into lock position.
NEVER ATTEMPT TO ACTIVATE SPINDLE LOCK
WHILE ROUTER MOTOR IS RUNNING OR
COASTING TO STOP.
2. Place your router upside down on a table, then
turn collet nut with wrench until lock mechanism
interlocks. See Fig. 3.' NOTE: Spindle lock is
spring loaded and will snap into position when
lock mechanism interlocks.
WARNING; IF YOU ARE CHANGING ABIT IM-
MEDIATELY AFTER USE, BE CAREFUL NOT TO
TOUCH THE BIT OR COLLET WITH YOUR
HANDS OR FINGERS, THEY WILL GET BURNED
BECAUSE OF THE HEAT BUILDUP FROM CUT,
TING, ALWAYS USE THE WRENCH PROVIDED.
3. •Remove cutters by turning collet nut counter
clockwise enough to allow cutter to slip easily
from collet. See Figure 4. The collet is machined
to precision tolerances to fit cutters with 1/4"
diameter shank size.
4. With your router still upside down on table, Insert
shank of cutter into collet. The shank of your cut-
ter should be close to but not touching bottom of
collet.
5. Tighten the :collet nut securely by turning clock-
wise with the wrench provided. See Fig, 4. Put
spindle lock back in unlock position. Otherwise
the interlocking mechanism of the spindle lock
will not let your router turn on.
WARNING: DO NOT USE CUTTERS WITH UN-
DERSIZED SHANKS. UNDERSIZED SHANKS
WILL NOT TIGHTEN PROPERLY AND COULD
BE THROWN FROM TOOL CAUSING INJURY.
DEPTH OF CUT ADJUSTMENTS
We recommend that cuts be made at a depth not ex-
ceeding 1/8" and that several passes be made to
reach depths of Cut greater than 1/8".
Disconnect router Irom power supply before ad-
justing for depth of cut.
1. Place the router on a flat surface, loosen clamp.
Ing Wing Nut, and turn depth adjusting ring until
cutter is inside subbase. See figure 5.
2. Turn the depth adjusting ring until tip of cutter
touches flat surface. Turn the depth indicator
ring until the zero lines Up with the indicator point
on the base. See figure 5.
3. Position the router so that the bit can extend
below the subbase for desired depth setting.
4. Turn the depth adjusting ring to obtain the de.
sired depth of cut. The distance the cutter moves
can be read on the depth indicator ring. Each
notch on the depth adjusting ring indicates 1/64
inch change in depth setting.
5. Tighten clamping wing nut securely before op-
erating router.
6, Plug your router into power supply source. Then
make the desired materJal and cutter size select-
Ions on the front panel.

ROUTING
See Figure 6.
For ease of operation and maintaining proper con-
trol, 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 Fig. 6
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 in-
dicator setting is at the "soft" position and the cut-
ter size setting Is at the "1/4 inch" position.
A change from the "hard" to "very hard" material in-
dicator 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 pro-
per 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. 7
power - and the router motor can become overload-
ed 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 par-
tially 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 RATE-
OF-FEED, MAKING SURE THE "TOO SLOW" IN-
DICATOR 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 for-
ward. 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 arevolving bit doesn't dig into new"
wood fast enough to take abite; instead, it simply
scrapes away sawdust-like particles. Scraping pro-
duces 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 revolv-
ing 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 rlppl-
ed, 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
The right feed isneither 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.
Good judgement with the proper use of the Elec-
tronic feature will give best results. You will learn by
experience .... by listening to the tool motor and by
feeling the progress of each cut. If at all possible,
always test cut on a scrap of the workpieoe wood,
beforehand.
DEPTH OF CUT
As previously mentiofled, the depth of cut is impor-
tant 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 ashallow one. A too
deep cut will cause you to slow the feed so much
that the bit will begin scraping instead of cutting.
Making ad'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.
DIRECTION OF FEED AND THRUST
The router motor and bit revolve in a clockwise dirac-
tion. This gives the tool a slight tendency to twist
(in your hands) in a counterclockwise direction.
Because of the extremely high speed of bit rotation
during a "proper feeding" operation, there is very lit-
tle kickback to contend with under normal condi-
tions. However, should the bit strike s knot, hard
grain, etc. that would affect the normal progress of
the cutting action, there will be aslight kickback --
sufficient to spoil the trueness of your cut if you are
not prepared. Such akickback is always in the direc-
tion 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 adirection 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.
DEPTH WIDTH
UT pe-OF CUT
Fig. 8
To make deeper cuts it is therefore necessary to
make as many successive passes as required, lower-
ing 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.

STARTING AND ENDING A CUT
INTERNAL ROUTING
Tilt Router and place on workplece, letting edge of
subbase contact workpiece first. Be careful not to let
Router bit contact workpieee. Turn Router on and let
motor build to Its full speed. Gradually feed cutter in-
to workpiece until subbase Is level with workplece.
WARNING: KEEP A FIRM GRIP ON ROUTER WITH
BOTH HANDS AT ALL TIMES. FAILURE TO DO SO
COULD RESULT IN LOSS OF CONTROL LEADING
TO POSSIBLE SERIOUS INJURY. Upon completion
of cut, turn motor off and let it come to acomplete
stop before removing Router from work surface.
WARNING: NEVER PULL ROUTER OUT OF WORK
AND PLACE UPSIDE DOWN ON WORK SURFACE
BEFORE THE MOTOR STOPS.
EDGE ROUTING
Place Router on workplece, making sure the Router
bit does not contact workpiece. Turn Router on and
let motor build to Its full speed. Begin your out,
gradually feeding cutter into workpiece. WARNING:
KEEP A FIRM GRIP ON ROUTER WITH BOTH
HANDS AT ALL TIMES, FAILURE TO DO SO COULD
RESULT IN LOSS OF CONTROL LEADING TO
POSSIBLE SERIOUS INJURY. Upon completion of
cut, turn motor off and let it come to a complete stop
before removing Router from work surface. WARN-
ING: NEVER PULL ROUTER OUT OF WORK AND
PLACE UPSIDE DOWN ON WORK SURFACE
BEFORE THE MOTOR STOPS.
EDGING WITH THE PILOT BITS
The arbor-type bits with pilots are excellent for
quick, easy edge shaping of any worl<piece edge that
is either straight or curved at a curvature as great or
greater than the radius of the bit to be used. The pilot
prevents the bit from malting too deep acut; and
holding the pilot firmly in contact with the workpiece
edge throughout prevents the cut from becoming
too shallow.
Whenever the workpiece thickness together with the
desired depth of cut (as adjusted by router depth set.
ting) are such that only the top part of the edge is to
be shaped (leaving at least a 1/16 in. thick uncut por-
tion at bottom), the pilot can ride against the uncut
portion, which will serve to guide it. See Fig. 12.
However, if the workpiece is too thin and/or the bit
set too low so that there will be no uncut edge to ride
the pilot against, any extra board to act as a guide
must be placed under the workpiece. This "guide"
board must have exactly the same contour --
straight or curved -- as the workpiece edge, If it is
positioned so that its edge is flush with the
workplece edge, the bit will make a full cut (In as far

positioned as shown In Fig, 12 (out from the
workpiece edge), the blt will make less than a full out

TYPICAL OPERATIONS
HELPFUL HINTS - MAKING CUTTER SIZE
SELECTIONS
AS you can see listed in the accessories, awide
variety of cutters is available. Therefore, there is a
variety of sizes, grooves, curves and angles involved.
This often creates the need to estimate the
AVERAGE CUTTING DIAMETER when making cutter
size selections on the front panel. The following ex-
amples Illustrate how to estimate, the average cut-
ting diameter. REMEMBER: We recommend that
cuts be made at a depth not exceeding 1/8" and that
several passes be made to reach depths of cut
greater than 1/8"
See Figure 13. In this illustration a V-groove cutter is
being used to make a5/16" deep cut. To find the
average cutting diameter, add the maximum
diameter (5/8") to the minimum diameter (0), then
multiply by 1/2. The average diameter of the cut
equals 5/16". Since 5116" lies between the "1/4
inch" and "3/8 inch" position on the front panel,
either could be used. Difficulty in controlling, dif-
ficulty in cutting, material hardness, etc. are factors
which can be used In determining which position to
select. For example, if the material was difficult to
cut, then the "3/8 inch" position would probably be
best since the cutting speed will be slower.
See Figure 14. In this illustration the V-groove cutter
is being used to make a cut with a 3/4" maximum
diameter. The m_ximum diameter is 3/4", the
minimum diameter is still 0", and the average
diameter Is now 3/8". In this case, the "3/8 Inch"
position would be the best cutter size selection.
NOTE: Your depth of cut would also be 3/8".
See Figure 15. This illustration shows acove cutter
with a non-zero minimum diameter. The average
diameter Is still computed by adding the maximum
diameter to the minimum diameter, then multiplying
by 1/2. For example, If the maximum diameter
equals 112" and the minimum diameter equals 3/8",
then the average diameter equals 7/16" (1/2 is the
same as 4/8, therefore, 4/8" + 3/8 = 7/8", 7/8" x
1/2 --. 7/16"). Either the "3/8 inch" or "1/2 Inch"
position could be selected on the front panel.
As mentioned earlier, it is best to make a trial cut on
a scrap piece of wood where possible. The average
diameter of the cutter can also be determined by
measuring the maximum and minimum diameter
from the widths of atrial cut. If necessary, then a
change or correction in the cutter size can be made
before making the finished cut.
HELPFUL HINTS _ USING CARBIDE TIPPED
CUTTERS
Since carbide cutters cut at higher speeds than steel
cutters, it often becomes necessary for the front
panel settings to be different while using carbide
cutters. As mentioned earlier, the "very hard" posi-
tion under the material indicator setting was design-
ed for using carbide cutters when cutting materials
that are too hard for steel cutters. However, carbide
cutters can also be used for cutting the same
materials that steel cutters cut.

When using carbide cutters to but these softer
materials, a good rule to remember Is to set either
the "material" or "cutter size" iridicator one position
above that recommended for steel cutters. For exam-
ple, a 1/2" carbide cutter should have the "3/8 inch"
selection on the front panel. If a 1/4" carbide cutter
is being used then the material indicator should be
moved up one position. For example, from "hard" to
"medium", or "'medium" to "soft".
The fastest speed at which your electronic router
will run is with the "soft" and "1/4 Inch" selections
on the front panel. This will be the fastest speed for
both carbide cutters and steel cutters (25,000 RPM,
no-load speed).

MAINTENANCE
WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS
PROPER CARE OF CUTTERS
Get faster more accurate cutting results by keeping
cutters clean and sharp. Remove all accumulated
pitch and gum from cutters after each use.
When sharpening cutter, sharpen only the Inside of
the cutting edge. Never grind the outside diameter.
Be surewhen sharpening the end era cutter to grind
the clearance angle the same as originally ground.
A cutter sharpening kit (cat. #66501) is available from
Sears Catalog Order or Retail Store. NOTE: WHEN
SHARPENING CUTTERS WITH YOUR ELECTRONIC
ROUTER, MAKE THE "SOFT" AND "t/4 INCH"
SELECTIONS ON THE FRONT PANEL.
PROPER CARE OF COLLET
From time to time, it also becomes necessary to
clean your collet and collet nut. To do so, simply
remove collet nut from collet and clean the dust and
chips that have collected. Then return collet nut to
its original position.
SWITCH REPLACEMENT
Disconnect router from power supply.
SWITCH REPLACEMENT IS AS FOLLOWS:
1. Remove screws (A) nuts !B) and handle covers ((3).
See Figure 16,
2. Note location of grommet (D) in handle end how
each lead Is connected to switch.
3. Remove leads from switch by inserting a 1/32"
diameter pin or nail into switoh lead receptacle as
shown in figure 16 and pulling on the lead.
Remove nail orpln with a twisting, pulling motion.
4, Make sure grommet (D) is on cord and push each
lead as far as possible into proper receptacle in
switch,
5. Locate switch in handle and place leads so they
won't be pinched when handle cover is replaced.
6. Make sure grommet (D) is in place and replace
handle cover, screws and nuts.

When electric tools are used on fiberglass boats,
sports cars, etc., it has been found that they are sub-
ject to accelerated wear and possible premature
failure, as the fiberglass chips and grinc!lngs are
highly abrasive to bearings, brushes, commutators,
etc. Consequently it is not recommended that this
tool be used for extended work on any fiberglass
material. During any use on fiberglass it is extremely
important that the tool Is cleaned frequently byblow-
Ing with an air jet. ALWAYS WEAR SAFETY
GLASSES OR EYESHIELDS BEFORE BEGINNING
THIS OPERATION.
TROUBLESHOOTING
PROBLEM
1, Router will not start -- indicator lights
do not flash.
2. Router will not start -- top two indicator
lights flash.
J .,, J
3. Any unusual router condition, or abnormal
flashing of lights.
4. Your router becomes overloaded and shuts
off. The "too slow" and "too fast" Indicator
lights begin flashing:
5. The "too slow" Indicator light does not
flash or flashes inconsistently.
6. The indicator lights do not shift when you
push the "select" region.
SOLUTION
1. (a)Maka sure your router is properly plugged
Into power supply.
(b) Make sure spindle lock is in unlocked
position.
2. The switch of your router is not In the
"off" position, NOTE: Any time your router is
disconnected from power supply and the
switch is locked In the "lock on" position,
this condition will exist.
.
4.
.
DisconneCt your router from power supply,
then plug it In again.
Turn the trigger switch to Its full "off"
position, walt a few seconds, then restart
your router and continue routing at a slower
rate of feed.
This condition exists because of low voltage
conditions in the power supply. Continue
to use your router as normal.
6. Firmly press the "select" region to clean
away sawdust, etc. that has collected on the
contacts.
