nentswithprotectinginsulation.
IMPORTANT -Servicingof a tool with double insulation
requiresextreme care and knowledgeof the system and
shouldbe performedonlybya qualifiedservicetechnician.

RULES FOR SAFE OPERATION
READ ALL INSTRUCTIONS
1. KNOW YOUR POWER TOOL - Read owner's
manual carefully.Learn itsapplicationsand limita-
tionsas well as the specific potential hazards re-
lated tothis tool.
2. GUARD AGAINST ELECTRICAL SHOCK BY
PREVENTING BODY CONTACT WITH
GROUNDED SURFACES. For example: Pipes,
radiators, ranges, refrigeratorenclosures.
3. KEEP GUARDS IN PLACE and In workingorder.
4. KEEP WORK AREA CLEAN. Clutteredareas and
benches inviteaccidents.
5. AVOID DANGEROUS ENVIRONMENT, Don't use
power tool in damp or wet locationsor expose to
rain. Keep work area well lit.
6. KEEP CHILDREN AND VISITORS AWAY. Allvisi-
torsshouldwear safety glasses and be kept a safe
distancefrom work area. Do not let visitorscontact
toolor extension cord.
7. STORE IDLE TOOLS. When not inusetoolsshould
be stored in a dry, high or locked-up place - out of
the reach ofchildren.
8. DON'T FORCE TOOL. It willdo the job better and
safer at the rate for which itwas designed.
9. USE RIGHT TOOL. Don't force small tool or at-
tachment 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.
10. WEAR PROPER APPAREL. No loose clothingor
jewelryto getcaught inmovingparts.Rubbergloves
and non-skid footwear are recommended when
workingoutdoors.Also,wear protective haircover-
ing to contain long hair and keep it from being
drawn intoair vents.
11. ALWAYS WEAR SAFETY GLASSES. Everyday
eyeglasses have only impact-resistantlenses;they
are NOT safety glasses.
12. PROTECT YOUR LUNGS. Wear a face or dust
mask ifcutting operation isdusty.
13. PROTECT YOUR HEARING. Wear hearing pro-
tection during extended periodsof operation.
14. DON'T ABUSE CORD. Never carry tool bycordor
yank it to disconnect from receptacle. Keep cord
from heat, oll and sharp edges.
15. SECURE WORK. Use clamps or a vise to hold
work. Bothhands are needed to operate the tool.
16. DON'T OVERREACH. Keep proper footing and
balance at all times. Do not use on a ladder or
unstable support.
17. MAINTAIN TOOLS WITH CARE. Keep toolssharp
at all times, and clean for best and safest perfor-
mance. Follow instructions for lubricating and
changing accessories.

RULES FOR SAFE OPERATION (Continued)
18. DISCONNECT TOOLS. When not in use, before 29.
servicing, or when changing attachments, blades,
bits,cutters, etc., all toolsshould be disconnected
from power supply. 30.
19. REMOVE ADJUSTING KEYS AND WRENCHES.
Form habitofchecking tosee thatkeys and adjust-
ingwrenches are removed from tool beforeturning
iton.
20. AVOID ACCIDENTAL STARTING. Don't carry
plugged-in tools with finger on switch. Be sure
switchIs offwhen plugging in.
21. MAKE SURE YOUR EXTENSION CORD IS IN
GOOD CONDITION. When using an extension
cord, be sure to use one heavy enoughtocarrythe
current yourproduct willdraw. An undersizedcord 31.
willcause a drop in linevoltage resultingin loss of
power and overheating. A wire gage size (A.W.G.)
of at least 14 is recommended for an extension 32.
cord 100 feet or less in length. A cord exceeding
100 feet is not recommended. If in doubt,use the 33.
next heavier gage. The smaller the gage number,
the heavier the cord.
22. OUTDOOR USE EXTENSION CORDS. When tool ,
is used outdoors, use only extension cords suit- 34.
able for use outdoors.Outdoor appi'ovedcordsare
marked withthe suffix W-A, for example - SJTW-A
or SJOW-A. 35.
23. KEEP CUTTERS CLEAN AND SHARP. Sharp
cutters minimize stallingand kickback. 36.
24, KEEP HANDS AWAY FROM CUTTING AREA.
Keep hands away from cutters. Do not reach un-
derneath work while cutter is rotating. Do not at-
tempt to remove material while cutter is rotating.
25. NEVER USE IN AN EXPLOSIVE ATMOSPHERE.
Normal sparkingof the motorcould ignitefumes.
26. INSPECT TOOL CORDS PERIODICALLY and if 37.
damaged, have repaired at your nearest Sears
Repair Center. Stay constantly aware of cordloca-
tion.
27. INSPECT EXTENSION CORDS PERIODICALLY
and replace ifdamaged.
28. KEEP HANDLES DRY, CLEAN, AND FREE
FROM OIL AND GREASE. Always use a clean
clothwhen cleaning. Never use brakqfluids, gaso-
line, petroleum-based products or any strong sol-
vents to clean yourtool.
STAY ALERT. Watch what you are doingand use
common sense. Do not operate tool when you are
tired. Do not rush.
CHECK DAMAGED PARTS. Before further useof
the tool, a guard or other part that is damaged
shouldbe carefullychecked to determinethat itwill
operateproperly and perform itsintendedfunction.
Check for alignment of moving pads, binding of
moving parts, breakage of parts, mounting, and
any otherconditions that may affect its operation.
A guard or other part that is damaged should be
propedy repaired or replaced by an authorized
service center unless indicated elsewhere in this
instructionmanual.
DO NOT USE TOOL IF SWITCH DOES NOT
TURN IT ON AND OFF. Have defective switches
replaced by an authorized service center.
Inspectfor and remove all nailsfrom lumberbefore
routing.
DO NOT USE TOOL UNDER "BROWN-OUT" OR
OTHER LOW VOLTAGE CONDITIONS. Also, do
not usewith any device that could causethe power
supplyvoltage to change.
DRUGS, ALCOHOL, MEDICATION. Do not oper-
ate toolwhile underthe influenceof drugs,alcohol,
or any medication.
WHEN SERVICING USE ONLY IDENTICAL
CRAFTSMAN REPLACEMENT PARTS.
POLARIZED PLUGS. To reducethe riskofelectric
shock, this tool has a polarized plug (one blade is
widerthan the other). This plugwillfit in a polarized
outletonlyone way. Iftheplugdoes notfit fully inthe
outlet, reverse the plug.Ifitstilldoes notfit, contact
aqualified electricianto installthe properoutlet.Do

PROPER FEEDING
The rightfeed isneither too fast nor too slow. It isthe rate at
whichthe bitis being advanced firmly and surely to produce
a continuous spiral of uniform chips -- without hogging into
thewood tomake large individual chips or, on the other hand,
tocreate 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, ifthe bitisa large one, the cut isdeep
or the wood ishard to cut, the proper feed may be a very slow
one.Then, again, a cross-grain cutmay require a slower pace
than an identical with grain cut in the same workplece.
There is no fixed rle. You will learn by expedence.,, by
listeningto the muter motor and by feeling the progress of
each cut. Ifat all possible, always test a cut on a scrap piece
of the workpiece wood, beforehand.
SPEED SELECTION
In general, if the material being cut is hard, the cutter size is
large, orthe depth ofcut isdeep (maximum 1/8 in.), then your
router shouldbe runat slower speeds. When these situations
exist,turnthevariable speed control selector untilthe desired
speed is reached. NOTE: Carbide cutters cut at higher
speeds than steel cutters and should be used when cuffing
very hard materials.

FORCEFEEDING
Clean,smoothroutingand edge shapingcan be doneonly
whenthe bit is revolvingat a relativelyhigh speed and is
takingverysmallbitestoproducetiny,cleanlyseveredchips.
Ifyourrouterisforced tomoveforward toofast, the RPMof
thebitbecomesslowerthannormalin relationtoitsforward
movement.As a result,the bit musttake biggerbitesas it
revolves."Biggerbites"mean biggerchips,and a rougher
finish. Biggerchipsalso requiremore power, whichcould
resultintheroutermotorbecomingoverloaded.

DEPTH OF CUT
Aspreviously mentioned, the depth ofcut isimportantbe-

qualityofa cut(and,also,thepossibilityof damagetoyour
routermotorandbit).A deepcutrequiresa slowerfeed than
a shallowone,anda toodeepcutwillcauseyoutoslowthe
feed somuchthatthe bit isno longercutting,itisscraping,
instead.
Makinga deep cut is never advisable.The smallerbits--
especiallythose only 1/16 inch in diameter ---are easily

OPERATION
STARTING AND ENDING A CUT
INTERNAL ROUTING
Tilt router and place on workpieca, letting edge of subbase
contact workpleoa first. Be careful notto let router bit contact
workpisce. Turn router on and let motor build to itsfullspeed.
Gradually feed cutter into workpleca until subbese is level
withworkplece.
UponcompleUonofcut,turnmotoroffand let itcometo a
completestopbeforeremovingrouterfromworksurface.
EDGING WITH PILOT BITS
The arbor-type bits with pilots are excellent for quick, easy,
edge shaping ofany workpleca edge that iseither straight or
curved at a curvature as great or greater than the radiusof the
bitto be used. The pilotprevents the bitfrom making toodeep
a cut;and holdingthe pilotfirmly Incontact withthe workpiece
edge throughoutprevents the cutfrom becoming too shallow.
Whenever the workpieca thickness together with the desired
depthof cut(as adjusted by routerdepth setting) are suchthat
onlythe top part of the edge isto be shaped (leaving at least
a 1/16 in. thick uncut portion at bottom), the pilot can ride
against the uncut portion, which will serve to guide it. See
Figure 13. However, ifthe workpiece istoo thin or the bitset
too low so that there will be no uncut edge to dde the pilot
against, an extra board toact as a guide mustbe placed under
the workplece. This "guide" board must have exactly the
same contour-- straight or curved---as the workplece edge.
If itis positioned so that its edge is flush with the workpiece
edge, the bitwill make afull cut (inas far as the bit radius).On
the other hand, if the guide ispositioned as shown in Figure
13 (out from the workplece edge), the bitwill make less than
afull cut -- which will alter the shape ofthe finished edge.
NOTE: Any of the piloted bits can be used without a pilotfor
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).
