technician. For service we suggest you return the tool
to your nearest Sears Store for repair. Always use
original factory replacement parts when servicing.
contact tool or extension cord.
• STORE IDLE TOOLS. When not in use, tools
should be stored in a dry and high or locked-up
place - out of the reach of children.
• DO NOT FORCE TOOL. It will do the job better
and safer at the rate for which it was designed.
• USE RIGHT TOOL. Don't force small tool or
attachment to do the job of a heavy duty tool.
Don't use tool for purpose not intended -- for
example -- don't use a circular saw for cutting tree
limbs or logs.
• WEAR PROPER APPAREL. Do not wear loose
clothing or jewelry that can get caught in tool's
moving parts and cause personal injury. Rubber
gloves and nonskid footwear are recommended
when working outdoors. Wear protective hair
covering to contain long hair and keep it from
being drawn into nearby air vents.
• ALWAYS WEAR SAFETY GLASSES. Everyday
eyeglasses have only impact-resistant lenses;
they are not safety glasses.
• PROTECT YOUR LUNGS. Wear a face or dust
mask if the operation is dusty.
• PROTECT YOUR HEARING. Wear hearing
protection during extended periods of operation.
• DO NOT ABUSE CORD. Never carry tool by cord
or yank it to disconnect from receptacle. Keep
cord from heat, oil, and sharp edges.

RULES FOR SAFE OPERATION (Continued)
• •SECURE WORK. Use clamps or a vise to hold
work. It is safer than using your hand and it frees
both hands to operate tool.
• DO NOT OVERREACH. Keep proper footing and
balance at all times. Do not use on a ladder or
unstable support. Secure tools when working at
elevated positions.
• MAINTAIN TOOLS WITH CARE. Keep tools
sharp and clean for best and safest performance.
Follow instructions for lubricating and changing
accessories.
• DISCONNECT TOOLS. When not in use, before
servicing, or when changing attachments, tools
should be disconnected from power supply.
• REMOVE ADJUSTING KEYS AND WRENCHES.
Form habit of checking to see that keys and
adjusting wrenches are removed from tool before
turning it on.
• AVOID ACCIDENTAL STARTING. Do not carry
plugged-in tool with finger on switch. Be sure
switch is off when plugging in.
• MAKE SURE YOUR EXTENSION CORD IS IN
GOOD CONDITION. When using an extension
cord, be sure to use one heavy enough to carry
the current y_'ur product will draw. 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 50 feet or less in length. A cord
exceeding 100 feet is not recommended. If in
doubt, use the next heavier gage. The smaller the
gage number, the heavier the cord.
• OUTDOOR USE EXTENSION CORDS. When
tool is used outdoors, use only extension cords
suitable for use outdoors. Outdoor approved
cords are marked with the suffix W-A, for
example - SJTW-A or SJOW-A.
• KEEP CUTTERS CLEAN AND SHARP. Sharp
cutters minimize stalling and kickback.
• KEEP HANDS AWAY FROM ROUTING AREA.
Keep hands away from cutters. Do notreach
underneath work while cutter isrotating. Do not
attempt to remove material while cutter is rotating.
• NEVER USE IN AN EXPLOSIVE
ATMOSPHERE. Normal sparking of the motor
could ignite fumes.
• INSPECT TOOL CORDS PERIODICALLY and if
damaged, have repaired at your nearest Sears
Repair Center. Stay constantly aware of cord
location.
• INSPECT EXTENSION CORDS
PERIODICALLY and replace if damaged.
• KEEP HANDLES DRY, CLEAN, AND FREE
FROM OIL AND GREASE. Always use a clean
cloth when cleaning. Never use brake fluids,
gasoline, petroleum-based products, or any
strong solvents to clean your tool.
• STAY ALERT AND EXERCISE CONTROL.
Watch what you are doing and use common
sense. Do not operate tool when you are tired. Do
not rush.
SAVE THESE INSTRUCTIONS
• CHECK DAMAGED PARTS. Before further use
of the tool, a guard or other part that is damaged
should be carefully checked to determine that it
will operate properly and perform its intended
function. Check for alignment of moving pads,
binding of moving pads, breakage of parts,
mounting and any other conditions that may affect
its operation. A guard or other part that is dam-
aged should be properly repaired or replaced by
an authorized service center.
• DO NOT USE TOOL IF SWITCH DOES NOT
TURN IT ON AND OFF. Have defective switches
replaced by an authorized service center.
• INSPECT FOR and remove all nails from lumber
before routing.
• DO NOT operate this tool while under the influ-
ence of drugs, alcohol, orany medication.
• POLARIZED PLUGS. To reduce the riskof
electric shock, this tool has a polarized plug (one
blade is wider than the other). This plugwill fit ina
polarized outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If itstill does
not fit, contact a qualified electrician to install the
proper outlet. Do not change the plug in any way.
• WHEN SERVICING USE ONLY IDENTICAL
CRAFTSMAN REPLACEMENT PARTS.
• WHEN USING THIS ROUTER WITH A ROUTER
TABLE, HELP PREVENT POSSIBLE SERIOUS
INJURY BY KEEPING THE CUTTER GUARDED
AT ALL TIMES. Use only router tables, with
guards, that have been designed for use on
reuters that are of this type, size, and weight.
• DO NOT USE TOOL UNDER "BROWNOUT" OR
OTHER LOW VOLTAGE CONDITIONS. Also, do
not use with any device that could cause the
power supply voltage to change.
• SAVE THESE INSTRUCTIONS. Refer to them
frequently and use them to instruct others who
may use this tool. Ifyou loan someone this tool,
loan them these instructions also.
WARNING: Some dust created by power
A
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals
known to cause cancer, birth defects or other
reproductive harm. Some examples of these
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and
other masonry products, and
• arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area, and
work with approved safety equipment, such as
those dust masks that are specially designed
to filter out microscopic particles.

ROUTING
See Figure 9.
Fig.9
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 9.
_. 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.
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.
RATE OF FEED
IMPORTANT: The whole "secret" of professional
routing and edge shaping lies in making a careful
setup for the cut to be made and in selecting the
proper rate of feed.
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, shallow
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 a very slow one. 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 rate of feed is
determined by listening to the sound of the router
motor and by feeling the progress of each cut. Always
test a cut on a scrap piece of the workpiece wood,
beforehand.
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 workpieee.
See Figure 10.
10
Page 11
TOOFAST
TOOSLOW Fig. 10
Your router is an extremely high-speed tool (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. 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 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, it simply 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.
tn 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 10.
"Too-slow feeding" can also cause 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 routing.
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.
DEPTH OF CUT
As previously mentioned, the depth of cut is important
because it affects 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, 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 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 Figure 11.

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 13, tool travel should be left to right and
counterclockwise around curves. When the guide is
positioned as shown in the second part of Figure 13
tool travel should be right to left and clockwise around
curves. If there is a choice, the first setup is generally
the easiest to use. In either case, the sideways thrust
you use is against the guide.
GUIDEOUTSIDE
Fig.12
DIRECTION OF FEED AND THRUST
The router motor 8rid 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. How-
ever, 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 inthe direction opposite tothe
direction of bit rotation.
To guard against such a kickback, plan your setup 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 -- 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 continu-
ously biting straight into new (uncut) wood.

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.
_, WARNING: Never pull router out of work and
place ups}de down on work surface before the
cutter stops.
EDGING WITH PILOT BITS
See Figure 14.
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 bit from 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 workpiece 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 14.
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 14 (out from the workpiece edge), the bit will
make less than a full cut -- which will alter the shape
of the finished edge.

ROUTER,_ORK I
WHOLE EDGESHAPING Fig. 14
Note: Any of the piloted bits can be used without a
pilot for edge shaping with guides, as preceding. The
size (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.
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.
_1, 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.
_ WARNING: Never pull router out of work and
place upside down on work surface before the
cutter stops.

FREEHAND ROUTING
See Figure 15.
._ r..._k--.----_
,_ WARNING: Do not use large router bits for
freehand routing. Use of large router bits when
freehand routing could cause loss of control or
create other hazardous conditions that could
cause possible serious personal injury. When
using a router table, large router bits should be
used for edging only. Do not use router bits that
are larger in diameter than the opening in router
base for any purpose.
ROUTING WITH STRAIGHT EDGE
OF SUE]BASE
See Figure 16.
FREEHANDROUTING
When used freehand, your 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:
• Routing letters, grooves, and patterns into wood.
See figure 15.
• Routing out the background, leaving the letters
or pattern raised above the surface.
When freehand routing, we suggest the following:
• Draw or layout the pattern on workpiece.
• Choose the appropriate cutter.
Note: A core box or V-groove bit is often used for
routing letters and engraving objects. Straight bits
and ball mills are often used to make relief
carvings. Veining bits are used to carve small,
intricate details.
• 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 guide
for the next pass.
• Do not rout deeper than 1/8 in. per pass or cut.

ROUTINGWITHSTRAIGHTEDGEOF
SUBBASEAGAINSTAN EDGEGUIDE Fig. 16
The subbase on your router has a straight edge. It
should be used when placing your router against an
edge guide or fence and routing grooves parallel to
the fence.
_, WARNING: Do not use with router tables that
fail to conform to safe woodworking practices and
offer proper guarding for the cutter. Failure to
comply can result in an accident causing possible
serious injury.

_, WARNING: When servicing, use only identical
Craftsman replacement parts. Use of any other
part may create a hazard or cause product
damage.
GENERAL
Only the parts shown on parts list, page 19, are
intended to be repaired or replaced by the customer.
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 damage from various
types of commercial solvents and may be damaged
by their use. Use clean cloths to remove dirt, carbon
dust, etc.
LUBRICATION
All of the bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore,
no further lubrication is required.
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.
A wire gage size (A.W.G.) of at least 14 is
recommended for an extension cord 50 feet or less in
length. When working outdoors, use an extension
cord that is suitable for outdoor use. The cord's jacket
wit! be marked WA.
_, 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_hat can damage, weaken or
destroy plastic.
It has been found that electric tools are subject to
accelerated wear and possible premature failure when
they are used on fiberglass boats, sports cars,
wallboard, spackling compounds, or plaster. The
chips and grindings from these materials are highly
abrasive to electric tool parts such as bearings,
brushes, commutators, etc. Consequently, it is not
recommended that this tool be used for extended
work on any fiberglass 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.
_, CAUTION: Keep extension cords away from the
cutting area and position the cord so that it will
not get caught on lumber, tools, etc., during
cutting 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.
Extension cords suitable for use with your router are
available at your nearest Sears Retail Store.

PROPER CARE OF cu'n'ERS
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 cutters, sharpen only the inside of
the cutting edge. 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 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.
HELPFUL HINTS
,/ Always clamp workpiece securely before routing.
•/ A safe operator is one who thinks ahead.
,/ Always wear eye protection when routing.
,/ Make setup adjustments carefully. Then double
check. Measure twice and cut once.
