SAFETY SYMBOLS The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols and the explanations with them deserve your careful attention and understanding. The symbol warnings do not, by themselves, eliminate any danger. The instructions and warnings they give are no substitutes for proper accident prevention measures.
SAFETY INSTRUCTIONS WARNING: Be sure to read and understand all instructions in this manual before using this router. Failure to follow all instructions may result electric shock, fire, and/or serious personal injury. WORK AREA SAFETY • Keep your work area clean and well lit. Cluttered workbenches and dark areas invite accidents. • Do not operate power tools in explosive environments, such as in the presence of flammable liquids, gases, or dust.
• D o not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations. • A lways secure your work. Use clamps or a vise to hold the workpiece securely. It is safer than using your hand, and it frees both hands to operate the tool. • U se safety equipment. Always wear eye protection. A dust mask, non-skid safety shoes, hardhat, and hearing protection must be used for appropriate conditions.
ELECTRICAL SAFETY WARNING: Do not permit fingers to touch the terminals of the plug when installing or removing the plug from the outlet. • D ouble insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way.
• E xtension cords 100-ft. or longer are not recommended. • A smaller wire gauge size has greater capacity than a larger number (14-gauge wire has more capacity than 16-gauge wire; 12-gauge wire has more capacity than 14-gauge). When in doubt use the smaller number. When operating a power tool outdoors, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock. CAUTION: Keep the extension cord clear of the working area.
• U se only identical replacement parts when servicing a tool. Follow the instructions in the maintenance section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury. SAFETY RULES FOR ROUTER CAUTION: Cutting bits coast after the router is switched off. • H old the tool by the insulated gripping surfaces (handles) when performing an operation where the cutting tool may contact hidden wiring or its own cord.
• K eep cutting pressure constant. Do not overload the motor. • U se only sharp cutting bits that are not chipped or cracked. Blunt cutting bits will cause stalling and burn the workpiece. • N ever use this router motor with a cutting bit larger than 1-1/2 inch in diameter. • A lways use cutting bits that are designed for this router. Never use cutting bits that are larger in diameter than the opening in the router sub-base.
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth or eyes or lie on the skin may promote absorption of harmful chemicals. WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and permanent respiratory or other injury. Always use NIOSH/ OSHA approved respiratory protection appropriate for the dust exposure.
unpacking WARNING: Your router should never be connected to a power source when you are assembling parts, making adjustments, installing or removing collets/ nuts or cutting bits, cleaning, or when it is not in use. Disconnecting the router will prevent accidental starting, which could cause serious personal injury. 1. C arefully lift the router, with the 1/4-in. collet/ nut already installed, out of the storage/carrying case and place it on a stable flat surface. 2.

operation ROCKER “ON/OFF” SWITCH (Fig. 3) Your palm router motor is turned “ON” and “OFF” with the rocker switch located on the top cap of the motor housing. Fig. 3 The left side of the rocker switch (as you face it) is marked “I” for “ON” and the right side (as you face it) is marked “O” for “Off.” To turn the motor “ON” Push the rocker switch to the left side marked “I” To turn the motor “OFF” Push the rocker switch to the right side marked “O” 1.
Electronic Variable Speed Control The electronic variable speed control feature allows the user to match the motor speed to the cutting bit size and workpiece-material hardness for an improved finish and extended bit life. Reduce the speed when using extra large (1-in. or greater) or heavy cutting bits. Changing the router’s rate of feed can also improve the quality of the cut. SELECTING THE CUTTING BIT This router comes with 1/4-in. collet/nut that accepts 1/4-inch-shank cutting bits.
INSTALLING AND REMOVING THE CUTTING BIT (Fig. 5) INSTALLING THE CUTTING BIT 1. T urn the motor off and unplug the router from the power source. Fig. 5 2. R emove the motor housing from the base. NOTE: See instructions for removing and installing the motor housing from the fixed base on page 20. 3. P lace the motor, upside down, on its top cap with the collet/nut pointing up. 4. P ress the spindle-lock button to engage and lock the spindle shaft and the collet/nut (Fig. 5). 5.
5. P lace the wrench on the collet/nut and turn it counterclockwise to slightly loosen the collet/nut, and then remove the cutting-bit shank from the collet/nut. NOTE: The collet/nut is self-releasing; it is not necessary to strike the collet/nut to free the cutting bit. If the cutting bit seems to be stuck, loosen the collet/nut a little more until it releases the cutting bit. COLLET/NUT CARE 1.
To Adjust Depth (Fig. 6) 1. T urn the motor off and unplug the tool from the power source. Fig. 6 A B 2. I nstall the router bit. The collet/nut can accept only bits with ¼-inch shanks. 3. W ith one hand holding the motor housing, open Motor Clamp (A). 4. R otate the Micro Adjust Knob (B) to raise or lower the motor to achieve the desired cutting depth. The direction of the rotation is marked on the Micro Adjust Knob (B). 5. Always use a ruler to confirm the cutting depth. 6.
PLACING THE PALM ROUTER ONTO THE WORKPIECE AND STARTING THE CUT WARNING: Before operating your router, follow all safety instructions in this manual. Failure to do so could result in serious personal injury. NOTE: Making test cuts is essential with most routing applications. A test cut gives information about the set-up, the router’s speed, the depth of cut, and how the cutting bit reacts to the workpiece.
2. T ap the nail or drive the screw into the workpiece at the center point of the planned arc or circle. 3. Proceed to rout according to the Operations instructions. HEAVY-DUTY EDGE GUIDE (Figs. 8, 8a) Your palm router comes with a Heavy-Duty Edge Guide. This edge guide can be used as an aid in routing applications, such as decorative edging, straight-edge planing, trimming, grooving, dadoing, and slotting. Fig. 8 To assemble: 1.
EDGE ROUTING OR INTERNAL ROUTING Edge routing (Fig. 9) Fig. 9 1. W ith the depth-of-cut set, place the router base plate on the edge of the workpiece, making sure that the cutting bit does not contact the workpiece. 2. C lamp an edge guide (or board or metal straightedge) in place, to help guide the router’s base when making an edge cut. 3. T urn the router “ON,” and let the motor reach the selected speed. 4. To begin the cut, gradually feed the cutting bit into the edge of the workpiece. 5.
Internal routing (Figs. 10, 10a, 10b, 11) 1. W ith the depth-of-cut set, tilt the router and place it on the workpiece with only the leading edge of the sub-base contacting the workpiece (Fig.10). 2. T urn the motor “ON” and allow the motor to reach the selected speed, being careful not to allow the cutting bit to contact the workpiece. 3. T o begin your cut, gradually feed the cutting bit into the workpiece until the sub-base is level with the workpiece (see Fig. 10a, 10b). 4.
EDGING WITH A PILOT BIT (Figs. 12 and 12a) Arbor-type bits with pilots are excellent for edge shaping any workpiece edge that is straight or is curved with a curvature that is equal to or greater than the radius of the bit that is used. The pilot prevents the bit from making a cut that is too deep; holding the pilot firmly in contact with the workpiece edge throughout the cutting process prevents the cut from becoming too shallow.
FEEDING THE ROUTER (Fig. 13) The secrets to professional-looking routing are careful set-up for the cut, proper depth-of cut-selection, knowing how the cutting bit reacts in the workpiece, and the rate and direction of feed of the router. DIRECTION OF FEED: EXTERNAL CUTS (Fig. 13) Direction 1 Rout End Grains First Bit Rotation 3 Direction Router Feed Router Feed Fig. 13 2 The router motor and cutting bit rotate clockwise. This requires the feed of the cutting bit to be from left to right (see Fig.
DIRECTION OF FEED - INTERNAL CUTS (Figs. 14 and 14a) When making an internal cut, such as a groove, dado, or slot, the edge guide, straight edge, or board guide must always be positioned on the right-hand side of the router as you make the cut (Fig. 14). When the guide is positioned on the right hand side of the router, the router travel should be from left to right and “counterclockwise” around curves (see Fig. 14). This counterclockwise action around the curve could cause “Climb cutting”.
RATE OF FEED (Figs. 15 and 15a) The proper rate of feed depends on several factors: the hardness and moisture content of the workpiece, the depth of cut, and the cutting diameter of the bit. When cutting shallow grooves in soft woods, such as pine, you may use a faster rate of feed. When making deep cuts in hardwoods, such as oak, you should use a slower rate of feed. Fig. 15 Bit Shank Cut TOO FAST Cutter FEEDING TOO RAPIDLY (Fig.
When the cutting bit is scraping instead of cutting, the router is more difficult to control as you feed it. With almost no load on the motor, the cutting bit has a tendency to bounce off the sides of the cut in the workpiece, producing a cut with a rippled finish instead of clean, straight sides. MAINTENANCE WARNING: To ensure safety and reliability, all repairs should be performed by a qualified service technician at a Craftsman Service Center.
5. B e certain that all moving parts are well lubricated, particularly after lengthy exposure to damp and/or dirty conditions. Refer to Collet/nut Care and Cutting Bits on page 19 for Collet/Nut care. REPLACEMENT OF CARBON BRUSHES (Fig. 16) Replacement brush sets are available through Craftsman Parts and Repair Centers. 1. U nplug the router motor before inspecting or replacing brushes. Fig. 16 Cap Ears Brushes 2. R eplace both carbon brushes when either has less than 1/4-in.
