RULES FOR SAFE OPERATION
DOUBLE INSULATION is a safety concept in electric
power tools which eliminates the need for the usual
three wire grounded power cord and grounded supply
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 internal
metal motor components with protecting insulation.

21. MAKE SURE YOUR EXTENSION CORD IS
IN GOOD CONDITION. When usinganextension
cord, be sure to use one heavy enough to carrythe
current your product willdraw. An undersized cord
will cause a drop in line voltage resulting in loss of
power and overheating. A wire gage size (A.W.G.)
of at least 14 is recommended for an extension
cord 25 feet or less in length. A cord exceeding 25
feet is not recommended. If in doubt, use the next
heavier gage. The smal_r the gage number, the
heavier the cord.
22. OUTDOOR USE EXTENSION CORDS. When
tool is used outdoors, use only extension cords
suitablefor use outdoors.Outdoor approved cords
are marked with the suffix W-A, for example -
SJTW-A or SJOW-A.
23. KEEP CUTTERS CLEAN AND SHARP.
Sharp cutters minimize stalling and kickback.
24. KEEP HANDS AWAY FROM CUTTING
AREA. Keep hands away from cutters. Do not
reach underneath work while cutter is rotating.
Do not attempt to remove material while cutter is
rotating.
25. NEVER USE IN AN EXPLOSIVE
ATMOSPHERE. Normal sparking of the motor
could ignite fumes.
26. INSPECT TOOL CORDS PERIODICALLY
and if damaged, have repaired at your nearest
Sears Repair Center. Stay constantly aware of
cord location.
27. INSPECT EXTENSION CORDS PERIODI-
CALLY and replace if damaged.
28. KEEP HANDLES DRY, CLEAN, AND FREE
FROM OIL AND GREASE. Always use aclean
clothwhen cleaning. Never use brake fluids, gaso-
line, petroleum-based products or any strong sol-
vents to clean your tool.
29. STAY ALERT. Watch what you are doing and
use common sense. Do not operate tool when
you are tired. Do not rush.
30. CHECK DAMAGED PARTS. Before further
use of the tool, a guard or other part that is
damaged should be carefully checked to deter-
mine that it will operate properly and perform its
intended function. Check for alignment of moving
parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may af-
fect its operation. A guard or other part that is
damaged should be properly repaired or replaced
by an authorized service center unless indicated
elsewhere in this instruction manual.

with the professional in mind, but its ease of operation allows the amateur to produce work which is beautiful and precise.
3.5 HORSEPOWER MOTOR
Your router has a powerful 3.5 horsepower motor with
sufficient power to handle the toughest routing jobs. The
motor also has externally accessible brushes for ease of
servicing.
SOFT START
The soft start feature builds motor RPM gradually to mini-
mize start-up torque. Pressing or releasing the "on-off"
trigger will turn your router on or off.
LARGEHANDLES
Your router has large oversized handles for easy handling
and maintaining proper control when routing. The left handle
allows you to set cutter depth of cut when making plunge
cuts, while the right handle provides easy access to the
"on-off" trigger, "lock-on" button, and variable speed control
selector. The handles have also been designed so that
they are comfortable and easy to grasp when operating in
different positions or at different angles.
DEPTH CONTROL KNOB
A large depth control knob makes precise depth of cut
changes possible. It also is very helpful when making depth
of cut changes with your router mounted upside clown on a
router table.
DEPTH STOP SYSTEM
The depth stop block located on the base of your router
provides three adjustable stops and three fixed stops for
quick depth of cut changes. Adepth adjustment scale
makes quick adjustments to depth of cut changes possible.
The spring loaded adjustment knob quick releases stop bar
by depressing center of knob.
1/4 IN. AND 1/2 IN. SHANK CAPACITY
Your router has a1/2 in, diameter collet that accepts cutters
with 1/2 in. shanks, A 1/4 in, col[et has been provided so
that cutters with 1/4 in, shank bits can also be used,
CHIP SHIELD
A clear plastic see-through chip shield has been provided
on the base of your router for protection against flying dust
and chips. It is designed to fit the front opening of the router
base.
POSILOCK SPINDLE LOCK
Aposilock spindle lock secures the spindle so that only one
wrench is needed to loosen collet nut and change cutters.
A spindle lock indicator light alerts you that spindle is
locked if you connect router to power supply before unlocking
spindle. NOTE: Your router will not run if spindle is locked.
"LOCK-ON" FEATURE"
Your router is equipped with a "lock-on" feature that is
convenient when continous operation for extended periods
of time is required.
VARIABLE SPEED SWITCH WITH ELECTRONIC
SPEED CONTROL (Feedback Switch)
Your router has advanced electronic features, designed to
assist you in getting the maximum use from your router. By
making proper speed selections, your router can be ad-
justed to specfic routing needs. This eliminates much of the
guess work previously needed to perform a given job. Both
the experienced and inexperienced router users benefit,
obtaining professional like result-_ with fewer job errors.
The variable speed control allows the router speed to be
adjusted from 10,000 to 22,000 rpm. The variable speed
control selelctor is conveniently located inside the right
ha[idle near the operator's thumb or hand.
Thl_ electronic feature of your router introduces the flexibility
of adjusting the motor speed to required job conditions. An
electronic speed control module senses the load applied to
the motor, and increases or decreases motor voltage to
compensate for and maintain desired RPM.
Speed can be set according to the approximate cutter diam-
eter you will be using and to the hardness of the material
being cut. The best cuts are made when the cutter is fed
through material at the proper rate of feed.
ROUTER ACCESSORIES
Your router comes equipped with several accessories. The
edge guide keeps the cutter parallel with an edge of the
workpiece when cutting grooves and rabbets. The roller
guide allows the router to be used to trim laminates and
make cuts parallel with an irregularly shaped edge. The
template guide bushing enables the router to follow a tem-
plate for making duplicate shapes.

DEPTH OF CUT ADJUSTMENTS
See Figures 6, 7 and 8.
When routing a groove that is too deep to safely cut in one
pass, it is best to make the cut in several passes. We
recommend that several passes be made to reach deeper
cuts.
Proper depth of cut depends on several factors: horsepowerof
router motor, type of cutter being used, and type of wood being
routed. A lightweight, low horsepower router is designed for
making shallow cuts. A router with high horsepower rating can
safely cut deeper. Small bits, such as 1/4 in. shank veining bits
with 1/16 in. cutting diameters, are designed to remove only
small amounts of wood. Larg,e bits, such as 1/2 in. shank
straight-flute bits, are made to remove larger amounts of wood
in a single pass. Cuts can be made deeper in soft woods, such
as white pine, than in tough hardwoods, like oak or maple.
Based upon these considerations, choose a depth of cut that
will not place excessive strain on router motor. If you find that
extra force is needed or that the motor speed slows down
considerably, turn off router and raise the bit. Then, make the
cut in two or more passes.
TO SET DEPTH OF CUT
1, UNPLUG YOUR ROUTER.
WARNING:
Failure to unplug your router could result in accidental
starting causing serious injury.
2. Raise cutter by depressing plunge release actuator.
See Figure 6.
3. Adjust depth control knob until cutter is inside router
subbase. See Figure 7.
4. Place router on a flat surface.
5. Lower router until tip of cutter barely touches flat sur-
face. See Figure 8.
6. Squeeze plunge lock actuator to lock cutter at "zero"
depth of cut. NOTE: If desired, adjust depth control
knob until hex nut comes in contact with stop flange.
This will provide a positive stop at "zero" depth of cut.
7. Rotate depth stop block to desired position, loosen
lock knob, then turn adjustment knob until stop bar
touches stop screw on depth stop block.
8. Slide zero-reset indicator up or down the scale on stop
bar until white line on zero-reset indicator aligns with a
desired reference point. For example, align white line
with 1 in. mark on the scale.
9. Next, turn adjustment knob in the opposite direction,
lifting stop bar to obtain desired depth of cut. See
Figure 8. For example, if setting 1/8 in. depth of cut,
the zero-reset indicator will move 1/8 in. from the 1 in.
reference point. Tighten knob securely.
Position your router so that the cutter can extend below
the subbase for desired depth setting.

return to it's uppermost position against hex nut.
4. Plunge router until cutter reaches the approximate
desired depth of cut. Then squeeze plunge lock
actuator, temporarily locking cutter at desired depth of
cut.
5. Turn depth control knob clockwise until hex nut seats
against stop flange. Do not overtighten hex nut
against stop flange.
6. Depress plunge release actuator and turn depth control
knob until cutter reaches desired depth of cut. Always
make sure plunge lock is released and router is
free before setting depth of cut with depth control
knob,
7. Squeeze plunge lock actuator, locking cutter at desired
depth of cut.
8. Turn adjustment knob and adjust stop bar until it
touches the desired stop screw or fixed stop.
9. Tighten lock knob securely.
Depth control knob is spring loaded against hex nut. If you
adjust it too far and it pops off threaded rod, refer to DEPTH
CONTROL KNOB ADJUSTMENTS in maintenance section
for proper reassembly.
DEPTH STOP SYSTEM
See Figure 10.
The depth stop block located on the base of your router
makes it possible to make deep or heavy cuts in successive
passes by use of preset depth of cut changes. Both fixed and
adjustable stops are provided, making depth of cut changes
quick and easy. The depth stop block, also known as a
revolving turret, rotates on a ball detent design in the router
base.
A preset cutting depth is achieved by plunging router until
stop bar comes in contact with the stop screw or fixed stop
on depth stop block.
The fixed stops are approximately 1/8 in. apart. The adjustable
stops have screws that may be adjusted approximately 1/2 in.

TO SET DEPTH STOP BLOCK SETTINGS
1. UNPLUG YOUR ROUTER.
2. Loosen lock knob and turn adjustment knob clockwise,
raising stop bar to it's highest position.
3. Determine which stop, adjustable or fixed, to use for
the desired depth of cut. A combination of the two stop
types can be used if required for a specific job. tf
using the adjustable stops, the stop screw on each
stop can be adjusted to the desired height by loosening
hex nut with the 3/8 in. end of combination wrench
supplied, and turning it in or out with your fingers.
Secure stop screw in position by retightening hex nut
with wrench. Do not overtighten hex nut, Set stops
to desired heights, spreading the entire depth of cut
over the number of stops used.
4. Rotate depth stop block until the highest depth stop is
aligned with the stop bar.

8. Turn adjustment knob counterclockwise to lower stop
bar against the stop, then tighten lock knob securely.
The highest stop now becomes the "zero"depth of cut
setting.
9. Depress plunge release actuator and raise router. Ro-
tate stop block so that next highest depth stop aligns
with stop bar. This locates cutter for the initial pass.
10. Rotate depth stop block after each pass. Make as
many sucessive passes as needed to obtain desired
depth of cut, progressively Iowedng routerto next depth
of cut setting with each pass.
ZERO RESET INDICATOR
See Figure 11.
The zero reset indicator allows you to use the scale provided
on the housing to make quick depth of cut changes to existing
depth of cut settings. Simply choose a reference point on the
scale and slide zero reset indicator up or down scale the
distance required for new depth of cut. Then change stop bar
position by loosening lock knob and turning adjustment knob
until white line on zero reset indicator moves back to refer-
ence point. Tighten lock knob securelyto lockstopbar in new
position. The cutter position will now increase or decrease
the exact distance the stop bar was adjusted.
Remember: Each mark on the inch scale indicates a 1/32
inch change in depth setting while each mark on the metric
scale equals a 1ram change in depth setting; depth control
knob should be used for making precise adjustments todepth
ofcut; and depressing center of depth adjustment knob quick
releases stop bar.
VARIABLE SPEED CONTROL SELECTOR
See Figure 12.
Your router has a variable speed control selector designed to
allow operator control of speed and torque limits. You can
make speed selections best suited to the type of cut, the
material being cut, and the size of bit being used. The variable
speed control selector allows you to adjust router speed from
10,000 to 22,000 rpm. There is a six step scale lettered A to
F on the variable speed control selector. To increase the
speed and torque of your router, turn the variable speed
control selector to a higher setting.Turn to a lower setting to
decrease speed and torque. NOTE: If you do not want to use
the variable speed control selector, turn to the highest pos-
sible setting, and the feature will not be active.

OPERATION
WARNING:
Always wear safety goggles or safety glasses with sid_
shields when using router. Failure to do so could result in
dust, shavings, chips, loose particles, or foreign objects
being thrown inyour eyes causing possible serious injury.
If operation is dusty, also wear a face or dust mask.
I
"LOCK-ON" BUTTON
See Figure 13.
The "on-off" trigger of your router is equipped with a "lock-
on" feature which is convenient when operating for ex-
tended periods of time. The "lock-on" button is located in
the upper portion of the "on-off" trigger. It works similar to a
rocker switch. To lock on, fully depress "on-off" trigger, then
depress "lock-on" button in top of "on-off" trigger and to-
lease. You will feel the "lock-on" button as it snaps "on-off"
trigger into lock position. To release the lock, depress pro-
truding portion of the "lock-on" button.
WARNING:
Before connecting router to power supply source, always
check to be sure switch is notin "lock-on"position. Failure
to do so could result in accidental starting of your router
causing possible serious injury.
b
ROUTING
See Figure 14.
For ease of operation and maintaining proper control, your
router has two handles, one on each side of the router base.
When using your router hold it firmly with both hands as
shown in figure 14.
Before starting router, make sure cutter is securely tightened
in collet nut and that depth of cut is properly set.
Turn router on and let motor build to its full speed, then
gradually plunge or feed cutter into workpiece. DO NOT let
the cutter contact workpiece before turning on router and
allowing it to develop full speed.
Remain alert and watch what you are doing. DO NOT operate
router when fatigued.
FEED DIRECTION
When routing, the cutter rotates clockwise. Therefore, you
should feed the router into the workpiece from left to right.
When fed from left to right, the rotation of the cutter pullsthe
router against the workpiece. If fad in the opposite direction,
the rotation forces of the spinning bit will tend to throw the
router away from the workpiece. This could cause loss of
control of your router.
RATE OF FEED
IMPORTANT: The whole "secret"of professional routingand
edge shaping lies in making a careful set-up for the cut to be
made and in selecting the proper rate of feed.
The proper rate of feed depends on several factors: the
PaGe 13
hardness and moisturecontent of the wood, the depth of cut,
and the cutting diameter of the bit. When cutting shallow
grooves in soft woods such as pine, a faster rate of feed can
be used. When making deep cuts in hardwoods such as oak,
a slower rate of feed will be required.
The best rate of feed is onethat does notslow down the router
motor more than one-third of its no-load speed. If the router
isfed too fast, itwill take large chips outof the wood and leave
gouge marks. If the routeris fed too slow, itwill scorch orbum
the wood.
OPERATION
PROPER FEEDING
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
a continuous spiral of 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,
shadow groove in soft, dry wood, the proper feed may be
about as fast as you can travel your router along your guide
line. On the other hand, if the bit is a large one, the cut is deep
or the wood is hard to cut, the proper feed may be avery slow
one. Then, again, a cross-grain cut may require a slower
pace than an identical with grain cut in the same workpiece.
There is no fixed rule. You will learn by experience from
practice and use. The best ra_teof feed is determined by
listening to the sound of the router motor and by feeling the
progress of each cut. If at all possible, always test a cut on a
scrap piece of the workpiece wood, beforehand.
SPEED SELECTION
tn general, if the material being cut is hard, the cutter size is
large, or the depth of cut is deep, then your router should be
run at slower speeds. When these situations exist, turn the
variable speed control selector until the desired speed is
reached. NOTE: Carbide cutters cut at higher speeds than
steel cutters and should be used when cutting very hard
materials.
FORCE FEEDING
Clean, smooth routing and edge shaping can be done only
when the bit is revolving at a relatively high speed and is
taking very small bites to produce tiny, cleanly severed chips.
If your router is forced to move forward too fast, the RPM of
the bit becomes slower than normal in relation to its forward
movement. As a result, the bit must take bigger bites as it
revolves. "Bigger bites" mean bigger chips, and a rougher
finish. Bigger chips also require more power, which could
result in the router motor becoming overloaded.
Under extreme force-feeding 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 Figure 15.
Your Craftsman router is an extremely high-speed tool (10,000
- 22,000 RPM no-load speed), and will make clean, smooth
cuts if allowed to run freely without the overload of a forced
(too fast) feed. Three things that cause "force feeding" are bit
size, depth-of-cut, and workpiece characteristics. The larger
the bit or the deeper the cut, the more slowly the router should
be moved forward. If the wood is very hard, knotty, gummy or
damp, the operation must be slowed still more.
You can always detect "force feeding" by the sound of the
motor. Its high-pitched whine will sound lower and stronger as
it loses speed. Also, the strain of holding the tool will be
noticeably increased.
TOO FAST
f
TOO SLOW Fig. 15
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 does not dig into new wood fast enough to take
a bite; instead, itsimply scrapes away sawdust-like particles.
Scraping produces heat, which can glaze, burn, or mar the
cut -- in extreme cases, can even overheat the bit so as to
destroy its hardness.
In addition, 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 at close to top RPM, 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 rippled, instead of straight sides. See Figure 15.
"Too-slow feeding" can a_socause your router to take off in a
wrong direction from the intended line of cut. Always grasp
and hold your router firmly with both hands when rout-
ing.
YOu can detect "too-slow feeding" by the runaway too-highly
pitched sound of the motor; or by feeling the "wiggle" of the bit
in the cut.
Page 14
OPERATION
DEPTH OF CUT
As previously mentioned, the depth of cut is important be-
cause it affects the rate of feed which, in turn, affects the
quality of a cut (and, also, the possibility of damage to your
bit). Adeep cut requires aslower feed than a shallow one, and
a too deep cut will cause you to slow the feed so much that
the bit is no longer cutting, it is scraping, instead.
Making a deep 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 and
control the bit as desired. For these reasons, we recommend
that several passes be made t_ reach deeper cuts. See
Figure 16.
To make deeper cuts it is therefore necessary to make as
many successive passes as required, lowering the bit 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 assu re a uniform depth when the final
pass is completed. See Figure 17.
DIRECTION OF FEED AND THRUST
See Figure 18.
The router motor and bit revolve in a clockwise direction. This
gives the tool a slight tendency to twist (in your hands) in a
counterclockwise direction, especially when the motor revs
up (as at starting).
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 a knot, hard grain, foreign object, 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 too!
-- to hold it against whatever you are using to guide the cut
-- in 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 bit continuously biting straight into new
(uncut) wood.
ROUTING
Whenever you are routing a groove, your travel should be in
a direction that places whatever guide you are using at the
right-hand side. In short, when the guide is positioned as
shown in the first part of Figure 19, tool travel should be left
to right and counterclockwise around curves. When the guide
is positioned as shown in the second part of Figure 19 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 use is against the
guide.

OPERATION
EDGE ROUTING
Place router on workpiece, making sure the router bit does
not contact workpiece. Turn router on and let motor build to
its full speed. Begin your cut, 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.
I
Upon completion of cut, turn motor off and let it come to
complete stop before removin_grouter from work surface.
Never pull router out of work and place upside down on
work surface before the cutter stops.
EDGING WITH PILOT BITS
See Figure 20.
Rabbets and molded edges can be cut using piloted cutters.
The pilot extends below the cutter. Some pilots are solid
extensions of the cutter. Others are ball bearing guides that
are fastened to the end of the cutter. The pilots allow the
cutterstotum while the pilotfollows the edge ofthe workpiece.
Arbor-type bits with pilots are excellent for quick, easy, edge
shaping. They will follow workpiece edges that are either
straight or curved. The pilot prevents the bitfrom making too
deep a cut; and holding the pilot firmly in contact with the
workpiece edge throughout prevents the cut from becoming
too shallow.
Whenever the wo rkpiece thickness together with the desired
depth of cut (as adjusted by router depth setting) are such that
only the top part of the edge is to be shaped (leaving at least
a 1/16 inch thick uncut portion at bottom), the pilot can ride
against the uncut portion, which will serve to guide it. See
Figure 20. However, if the workpiece is too thin or the bit set
too low so that there will be no uncut edge to ride the pilot
against, an 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 workpiece
edge, the bit will make a full cut (in as far as the bit radius). On
the other hand, if the guide is positioned as shown in Figure
20 (out from the workpiece edge), the bit will make less than
a full cut -- which will alter the shape of the finished edge.
NOTE: If desired, any of the piloted bits can be used without
a.pilot for edge shaping with guides, as preceding. Also, the
stze (diameter) of the pilot that is used determines the
maximum cut width that can be made with the pilot against the
workpiece edge (the small pilot exposes all of the bit; the large
one reduces this amount by 1/16 inch).

OPERATION
ROUTING GROOVES
See Figure 22.
When muting across the face of boards, set router at desired
depth of cut, place the edge of router base against workpiece,
and turn on your router. Slowly feed the cutter into the
workpiece along desired cutline.
WARNING:
If desired depth of cut is greater than can be safely cut in
one pass, make cuts in two or more passes.
When routing straight cuts across stock, clamp a straight-
edge to the workpiece to use as a guide. Position the
straightedge parallel to the cutline and offset the distance
between the cutting edge of the cutter and the edge of the
router base. Hold the muter base against the straightedge
and rout the groove.
When muting a groove wider than the diameter of the cutter,
clamp a straightedge on both sides of the cutting line.
Position both guides parallel to the desired cutline and
spaced equal distances from the desired edges ofthe gmove.
Rout along one guide; then, reverse direction and rout along
the other guide. Clean out any remaining waste inthe center
of the groove freehand.
ROUTING WITH EDGE GUIDE
See Figures 23 and 24.
Straight cuts and grooves can also be routed using an edge
guide attachment on your router. The edge guide attaches to
a guide holder, then the guide bars fit into openings in the
router base. Knob screws in the base secure the guide bars
in position.
Adjustments are made by loosening the wing bolt on guide
holder, placing the edge guide the desired distance from the
cutter, then retightening wing bolt. Fine adjustments can be
made with edge guide adjustment knob on the end of guide
holder. When routing with the edge guide attachment, hold
edge guide against the edge of workpiece as shown in figure
24.
ROUTING CIRCLES WITH EDGE GUIDE
See Figure 25.
The edge guide attachment can be used for routing circles
when a piloted bit is not available or inadequate for the
required job. Position the edge guide so that the cutter is in
the center opening of the edge guide. Keep both corners of
edge guide pressed against the edge to maintain aconsistent
shape.
When routing the outside edge (perimeter) of a circle, feed
the muter counterclockwise. When muting the inside of a
circle feed the router clockwise as shown in figure 25.
Remember that the rotation of the bit must always lead into
the workpiece rather than away from it.

OPERATION
ROUTING WITH A ROLLER GUIDE
See Figures 26 and 27.
A roller guide has been supplied with your router. It is useful
for routing uneven edges and trimming laminates.
The roller guide attaches to the guide holder as shown in
figure 26. It can be adjusted inand outas wellas upand down.
The roller guide rides against the uncut edge of the workpiece.
When routinga decorative groove along an uneven edge, the
distance from roller guide to cutter should be the same as the
distance from the desired cut and the edge of the workpiece.
Fine adjustments can be made with the edge guide adjust-
ment knob on guide holder. Tighten wing bolts securely.
When routing, keep roller p_essed tight against edge of
workpiece. Carefully follow desired line of cut so that the
distance between the cut and the edge does not vary.
When trimming laminates with the roller guide, use a straight
cutting bit or a roundnose bit. Position the roller guide even
with the inside cutting edge of router bit. The roller guide
follows the edge of the workpiece while the bit trims off the
overhanging laminate. See Figure 27.
ROUTING WITH GUIDE BUSHINGS
See Figures 28 and 29.
You can accurately duplicate curves and complex shapes by
fittingyour router with a template guide bushing that extends
below the subbase. The router bit passes through the guide
bushing, The guide bushing then rides against a template.
TO INSTALL TEMPLATE GUIDE BUSHING:
1. UNPLUG YOUR ROUTER.
WARNING:
2. Place router upside down on workbench.
3. Place template guide bushing in recessed portion of
router base as shown in figure 28.
4. Align the cutouts in guide bushing with threaded holes
in base.
5. Secure guide bushing to router base with roundhead
screws provided.
6. Tighten screws securely.
Failure to tighten screws could cause bit to come in
contact with bushing resulting in serious injury.

the collar of the guide bushing against the edge of the
template. Lowercutter intothe workpiece and proceed around
template, keeping guide bushing pressed against template
edge.
When routing with template guide bushings it is necessary to
allow for the size difference between the cutting edge of the
cutter and the face of the guide bushing collar. When making
templates, always allow for this size difference. See Figure
9.
FREEHAND ROUTING
See Figure 30.
When used freehand, your plunge router becomes a flexible
and versatile tool. This flexibility makes it possible to easily
rout signs, relief sculptures, etc.
There are two basic techniques for freehand routing:
1. Routing letters, grooves, and patterns into wood.
2. Routing out the background, leaving the letters or pat-
tern raised above the surface as shown in figure 30.
When freehand routing, we suggest the folowing:
1. Draw or layout the pattern on workpiece.
2. Choose the appropriate cutter. NOTE: A core box or
V-groove bit is often used for routing letters and en-
graving objects. Straight bits and ball mills are often
used to make relief carvings. Veining bits are used to
carve small, intricate details.
3. Rout the pattern in two or more passes. Make the first
pass at 25% of the desired depth of cut. This will
provide better control as well as being a quide for the
next pass.
Freehand routing is an excellent example of how to use
the plunge routing feature of your router:
1. Choose the appropriate cutter, set desired depth of
cut, carefully check set-up, and secure workpiece.
2. Make a test cut in a scrap piece of wood from the same
workpiece if possible.
3. Depress plunge release actuator and raise cutter from
any preset depth of cut. This also permits raising cutter
inside router subbase.
4. Place router on workpiece inside pattern to be routed.
5. Grasp handles securely and depress "on-off" trigger to
start your router.
6. Let motor build to full speed, then gradually plunge
cutter into workpiece until stop bar comes into contact
with stop screw on depth stop block.
7. Squeeze plunge lock actuator to secure depth of cut
setting.
8.- Begin routing out the pattern, continuing until a com-
plete pass at this depth of cut has been made.

MAINTENANCE
WARNING:
When servicing use only identical Craftsman replacement
parts. Use of any other parts may create a hazard or
cause product damage.
GENERAL
Only the parts shown on parts list, page 27, are intended to be
repaired or replaced bythecustomer. All other parts represent
an important part of the double insulation system and should
be serviced only by a qualified Sears service technician.
Avoid using solvents when cleaning plastic parts. Most plastics
are susceptible to various type_ of commercial solvents and
may be damaged by their use. Use clean cloths to remove
dirt, carbon dust, etc.
When electric tools are used on fiberglass boats, sports cars,
wallboard, spackling compounds, or plaster, it has been
found that they are subject to accelerated wear and possible
premature failure, as the fiberglass chips and grindings are
highly abrasive to bearings, brushes, commutators, etc.
Consequently it is notrecommended that thistool be usedfor
extended workon anyfiberglass material, wallboard, spackling
compounds, or plaster. During any use on these materials, it
is extremely important that the tool is cleaned frequently by
blowing with an air jet.
WARNING:
Always wear safety goggles, or safety glasses with side
shields during power tool operation or when blowing dust
if operation is dusty, also wear a dust mask.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum.
based products, penetrating oils, etc. come in contact
with plastic parts. They contain chemicals that can damage,
weaken, or destroy plastic.
LUBRICATION
All of the bearings inthis tool are lubricated with asufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrication
is required.
Page 20
MAINTENANCE
PROPER CARE OF CU'I-rERS
Get faster more accurate cutting results by keeping cutters
clean and sharp. Remove allaccumulated pitchand gum from
cutters after each use.
When sharpening cutters, sharpen only the inside of the
cuttingedge. Never grind the outside diameter. Be sure when
sharpening the end of a cutter to grind the clearance angle the
same as originally ground.
PROPER CARE OFCOLLET
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
retum collet nut to its original position.
BRUSH REPLACEMENT
See Figure 31.
Your router has externally aceessible brush assemblies
that should periodically be checked for wear.
PROCEED AS FOLLOWS WHEN REPLACEMENT IS
REQUIRED:
1. UNPLUG YOUR ROUTER.
WARNING:
Failure to unplug your router could result in accidental
starting causing serious injury.
2. Remove brush cap with a screwdriver. Brushassembl
is spring loaded and will pop out when you remove
brush cap.
3. Remove brush assembly (brush and spring).
4. Check for wear. If worn, always replace in pairs. Do
not replace one side without replacing the other.
5. Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.
6. Replace brush cap and tighten securely.
EXTENSION CORDS
The use of any extension cord will cause some loss of power.
To keep the loss to a minimum and to prevent tool overheating,
use an extension cord that is heavy enough to carry the
current the tool will draw.
Awire gage size (A.W.G.) of at least 14 is recommended for
an extension cord 25 feet or less in length. When working
outdoors, use an extension cord that is suitable for outdoor
use. The cord's jacket will be marked WA.
CAUTION:
Keep extension cords away from any routing area and
position the cord so that it will not get caught on lumber,
tools, etc., during routing operation.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use tool with a damaged
cord since touching the damaged area could cause
electrical shock resulting in serious injury.

PLUNGE LOCK ACTUATOR ADJUSTMENTS
See Figure 32.
The plunge lock actuator has been properly set at the
factory and no initial adjustments should be required. How-
ever, after extended use slight readjustment may be re-
quired, if this situation occurs, make adjustments as fol-
lows:
1. UNPLUG YOUR ROUTER.
WARNING: I
Failure to unplug your router could result in accidental
starting causing serious injUl"y.
2. Remove lock handle cover screws and lock handle
cover. See Figure 32.
3. NOTE THE LOCATION OF PLUNGE RELEASE AC-
TUATOR AND COMPRESSION SPRING IN HANDLE,
Reaasembly of all parts removed must be identical
in order for plunge lock and plunge release actua-
tors to function properly.
4. Loosen hex nut on bottom of plunge lock actuator with
a 7/16 in. open end wrench.
5. Loosen socket head screw with a 1/8 in. hex key (allen
wrench). This step is needed to make sure screw is
not making contact with rod in base assembly.
6. Depress plunge lockactuator untilit is flush with handle
as shown in figure 33.
7. Continue to hold plunge lock actuator flush with handle,
then turn hex key clockwise until socket head screw
touches base assembly rod. IMPORTANT: Do not
overtighten screw.
8. Make sure hex nut remains loose while tightening
socket head screw•
9. Once socket head screw touches base assembly rod,
secure it by tightening hex nut against plunge lock
• actuator.
10. Do not let socket head screw slip or turn while tighten-
ing hex nut.
11. Slip compression spring over peg on plunge release
actuator. Then locate tabs on actuator in slide grooves.
Make sure that end of compression spring rests against
wall of stop pocket.
12. Carefully replace handle cover and handle cover
screws. Make sure plunge release actuator and com-
pression spring are properly seated.
13. Tighten handle cover screws securely.
When properly adjusted, plunge lock actuator will make
contact with base assembly rod when it is flush with handle.
By squeezing plunge lock actuator past this point, a friction
lock situation occurs. This is what locks your router at
desired depth of cut settings.
The plunge release actuator is spring loaded. When en-
gaged, it pushes the plunge lock actuator past the flush
point in the opposite direction. This loosens socket head
screw, releasing pressure from rod in base assembly, Page 22

ROUTER TABLES
WARNING:
Do not use with router tables that fail to conform to safe
wood working practices and offer proper guarding for the
cutter. Failu re to comply can result in an accident causing
possible serious injury.
If mounting your router to a router table, use only the three
5/16-18 UNC-2B tapped holes provided in the router base.
