CAUTION

• The operation of any Router can result In foreign objects being thrown into your eyes, which can result In severe eye damage.
• Before commencing power tool operation, always wear safety goggles or safety glasses with side shields and a full face shield when needed.
• We recommend wide vision safety masks for use over spectacles or standard safety glasses with side shields, available at Sears Catalog Order or Retail Stores.

KNOW YOUR ROUTER

Before attempting to use your router, familiarize yourself with all operating features and safety requirements See Figure 1

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 INJURY.

CHIP SHIELD

• A clear plastic chip shield is installed on the front of your router to protect 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 remove, and squeeze the tabs on each end and pull outward.
• To replace, squeeze the tabs at each end, fit them into the opening, and then release FOR YOUR PROTECTION DO NOT USE THE ROUTER WITHOUT CHIP SHIELD PROPERLY IN PLACE.

SWITCH

• The switch of your router is equipped with a “lock-on” feature which is convenient when operating for extended periods To lock on, depress the trigger, push the lock button located on the side of the handle, then while holding the lock button push in, release the trigger To release the lock, depress the trigger and release it.

WARNING: BEFORE CONNECTING YOUR ROUTER TO THE POWER SUPPLY SOURCE, ALWAYS CHECK TO BE SURE THE SWITCH IS NOT IN LOCK-ON POSITION, FAILURE TO DO SO COULD RESULT IN THE ACCIDENTAL STARTING OF YOUR ROUTER RESULTING IN POSSIBLE SERIOUS INJURY.

INSTALLING REMOVING

INSTALLING/REMOVING CUTTERS See Figures 2 & 3

1. UNPLUG YOUR ROUTER
   • WARNING: FAILURE TO UNPLUG YOUR ROUTER COULD RESULT IN ACCIDENTAL STAR. TING CAUSING SERIOUS INJURY.
2. A spindle lock is located on the front of the motor housing See Figure 1 To activate the lock, push the spindle lock in and slide into the lock position. NEVER ATTEMPT TO ACTIVATE THE SPINDLE LOCK WHILE THE ROUTER MOTOR IS RUNNING OR COASTING TO A STOP.
3. Place your router upside down on a table, then turn the collet nut with a wrench until the lock mechanism interlocks See Figure 2 NOTE: Spindle look is spring loaded and will snap into position when the lock mechanism Interlocks.
   • WARNING: IF YOU ARE CHANGING A CUTTER IMMEDIATELY AFTER USE, BE CAREFUL NOT TO TOUCH THE CUTTER OR COLLET WITH YOUR HANDS OR FINGERS. THEY WILL GET BURNED BECAUSE OF THE HEAT BUILDUP FROM CUTTING. ALWAYS USE THE WRENCH PROVIDED.
4. Remove cutters by turning the court nut counterclockwise enough to allow the cutter to slip easily from the collet. See Figure 3 The collet is machined to precision tolerances to fit cutters with 1/4″ diameter shank size
5. With your router still upside down on the table, insert the shank of the cutter Into collet The shank of your cut. ter should be close to but not touching the bottom of the collet
6. Tighten the collet nut securely by turning clockwise with the wrench provided See Figure 3 Put the spindle lock back in the unlock position Otherwise, the interlocking mechanism of the spindle lock will not let your router turn on.

DEPTH OF CUT ADJUSTMENTS

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″

1. UNPLUG YOUR ROUTER.
   • WARNING: FAILURE TO UNPLUG YOUR ROUTER COULD RESULT IN ACCIDENTAL STAR- TING CAUSING SERIOUS INJURY.
2. Place your router on a flat surface, and loosen the clamp. ing wing nut, and adjust until the cutter is inside the sub-base. See Figure 4.
3. Turn the depth-adjusting ring until the tip of the cutter touches a flat surface. Turn the depth indicator ring until the zero lines up with the indicator point on the base. See Figure 4.
4. Position your router so that the bit can extend below the subbase for the desired depth setting.
5. Turn the depth-adjusting ring to obtain the desired depth of cut. The distance the cutter moves can be read on the depth Indicator ring. Each notch on the depth adjusting ring indicates a 1/64-inch change in depth setting.
6. Tighten the clamping wing nut securely before operating the router.
   • WARNING: BE CERTAIN THE CLAM PING WING NUT IS FIRMLY TIGHTENED FAILURE TO DO THIS WILL RESULT IN THE MOTOR MOVING INSIDE THE BASE, CAUSING AN UNEVEN CUT. THIS COULD CAUSE LOSS OF CONTROL RESULTING IN POSSIBLE, SERIOUS INJURIES
   • WARNING: ALWAYS WEAR SAFETY GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHEN USING YOUR ROUTER. FAILURE TO DO SO COULD RESULT IN DUST OR CHIPS BEING THROWN IN YOUR EYES RESULTING IN POSSIBLY SERIOUS INJURY. IF THE CUTTING OPERA: TION IS DUSTY ALSO WEAR A FACE OR DUST
7. ROUTING See Figure 5
   • 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 5.
   • Turn the router on and let the motor bulld to its full speed, then gradually feed the cutter into the workplace. Remain alert and watch what you are doing DO NOT operate the router when fatigued.

RATE.OF-FEED

• IMPORTANT: The whole “secret” of professional routing and edge shaping is 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 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 to its forward move.
• Ment 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 workplace See Figure 6.
• Your Craftsman Router is an extremely high-speed tool (25,000 rpm no-load speed) and will make clean, smooth cuts to allow it 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 can 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 _t 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 b_t 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 6
• “Too-slow feeding” can also cause your router to take off in the 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, the too-highly pitched sound of the motor; or by feeling the “wiggle” of the bit in the cut.

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 Indlvidua! 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 guideline.
• 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 Then, again, a cross-grain cut may require a slower pace than a dentlcal with grain cut in the same workpiece
• There is no fixed rule. You will learn by experience by listening to 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

DEPTH OF CUT

• As previously mentioned, the depth of cut is important because If 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 7.
• To make deeper cuts it is therefore necessary to make as many successive passes as required, lowering the bit 1/8 inch for each new pass. 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 Figure 8

DIRECTION OF FEED AND THRUST

• The router motor and bit revolve in a clockwise direction. This gives the tool a slight tendency to twist (in your hands) the clay when the mounters wis at stirring,
• Because the three high sion, the lit very in. tie 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 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 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 on the right-hand side.
• In short, when the guide Is positioned as shown in the first part of Figure 9, tool travel should be left to right and counterclockwise around curves.
• When the guide is positioned as shown in the second part of Figure 9 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.

STARTING AND ENDING A CUT

• INTERNAL ROUTING
  • Tilt the router and place it on the workpiece, letting the edge of the subbase contact the workpiece first. Be careful not to let the router bit contact the workpiece. Turn the router on and let the motor build to its full speed. Gradually feed cutter into workpiece until subbase Is level with the 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 the cut, turn the motor off and let it come to a complete stop before removing router from the work surface
  • WARNING: NEVER PULL THE ROUTER OUT OF WORK AND PLACE UPSIDE DOWN ON WORK SURFACE BEFORE THE CUTTER STOPS. ROTATING.

EDGING WITH THE PILOT BITS

• The ambrotype bits with pilots are excellent for quick easy, edge shaping of any workpiece 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 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) is such that only the top part of the edge is to be shaped (leaving at least a 1/16 in thick uncut portion at the bottom), the pilot can ride against the uncut portion, which will serve to guide it. See Figure 10.
• 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 the same contour – straight or curved — as the workplace edge. If it Is positioned so that its edge is flush with the workpiece edge, the bit will make a full cut (as far as the bit radius) On the other hand, if the guide is positioned as shown in Figure 10 (out from the workpiece edge), the bit will make less than a fuil cut – which will alter the shape of the finished edge
• 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 ex- poses all of the bit; the large one reduces this amount by 1/16 inch)

EDGE ROUTING

• Place the router on the workpiece, ensuring the router bit does not contact the workplace. Turn the router on and let the motor build to its full speed. Begin your cut, gradually feeding the cutter into the 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 the cut, turn the motor off and let it come to a complete stop before removing router from the work surface.
• WARNING: NEVER PULL THE ROUTER OUT OF WORK AND PLACE IT UPSIDE DOWN ON WORK SURFACE BEFORE THE CUTTER STOPS ROTATING:

ROUTING WITH GUIDE BUSHINGS

• When using the Template Guide Bushings Cat No. 9-25082 with your router you must visually center the bit with the bushing before beginning your out Your router subbase may be adjusted by loosening the screws holding the subbase to your router.
• Be sure the clamping wing nut is securely tightened before centring the bit In bushing After centring the bit with bushing tighten the screws firmly.
• WARNING: FAILURE TO CENTER BIT. WITH BUSHING OR TO FIRMLY TIGHTEN SCREWS AFTER CENTERING COULD CAUSE THE BIT TO COME IN CONTACT WITH THE BUSHING RESULTING IN SERIOUS IN JURY.

EXTENSION CORDS

• The use of any extension cord will cause some loss of power.
• To keep the loss to a minimum and prevent tool overheating, follow the recommended cord sizes on the chart at right.
• When the tool is used outdoors, use only extension cords suitable for outdoor use and so marked.
• Extension cords are available at Sears Catalog Order or Retail Stores.
