CUTTER BITS Get faster, more accurate cutting results by keeping cutter bits clean and sharp. Remove all accumulated pitch and gum from cutter bits after each use. When sharpening cutter bits, sharpen only the inside of the cutting edge. Never grind the outside diameter. Be sure, when sharpening the end of a cutter bit, to grind the clearance angle the same as was originally ground.
4. With the motor housing slot (C) aligned with the plunge base pin (D), lower the motor housing into the plunge base, engaging the pin into the slot. 5. Slide the motor into the base as far as it will go. 6. Close the motor clamp securely. REMOVING THE MOTOR FROM THE BASES To Remove the Motor from the Fixed Base (see Fig. 4) 1. Turn router motor off and unplug from power source. 2. Place router (fixed base/router 3. With back of router facing you, open the router motor clamp (A). 4.
DEPTH ADJUSTMENT WITH FIXED BASE (Figs. 6 and 7) NOTE: All depth adjustments clamp open. on the fixed base must be made with the motor NOTE: For all fixed base routers, the cutter bit depth equals the amount cutter that is exposed below the surface of the sub-base. The fixed base is designed with a micrometer-fine adjustment system. When the bit is lowered to the of the Fig. 6 approximate position desired (coarse setting), the system can then be micro-adjusted to the precise depth.
3. With the cutter bit already installed, press in the Coarse Adjustment Knob (B) and lower the motor into the base until the cutter bit is very close to the flat surface on which the base is sitting. Turn the Fine Adjustment Dial (C) until the cutter bit "just" touches the flat surface on which the base is sitting. Then lock the Motor Clamp (A). 4.
PLUNGING ACTION (Fig. 8) The plunge base feature simplifies the depth adjustments and allows the cutter bit to be accurately lowered down into the workpiece for more precise set-ups. To lower the cutter bit, release the plungelock lever by moving it "Up" to the unlocked position. Apply an even downward pressure on the plunge action until the cutter bit reaches the desired depth, then move the plunge-lock lever "Down" to the locked position.
6. To set a desired cutting depth, slide the depth-stop rod up until the red line on the clear plastic depth indicator points to your desired cutting depth on the depth scale (E). Secure the depth-stop rod at this position by tightening the depth-rod locking knob (C). 7. Unlock the plunge depth locking retract to the up position. 8. The desired depth-of-cut may now be achieved by plunging the router down until the depth-stop rod contacts the selected step on the depth-stop turret.
To use the micro-adjustment knob after the depth rod and turret have been set, check the final depth setting and micro-adjust as follows: • To micro-increase the plunge depth, raise the micro-adjustment screw by turning the knob counterclockwise the desired amount. To micro-reduce the plunge depth, lower the micro-adjustment screw by turning the knob clockwise the desired amount. TOGGLE "ON/OFF" SWITCH (Fig.
"LIVE TOOL INDICATOR" LIGHT (Fig. 13) Fig. 13 Your router also has a "Live Tool Indicator" green light, located on the motor housing top cap where the power cord enters the motor housing. This green light is always on when the router motor is plugged into a power source. HEAVY-DUTY EDGE GUIDE The router combo kit comes with a heavy duty edge guide.
ELECTRONIC VARIABLE SPEED CONTROL The electronic speed control feature allows motor speed to be matched to cutter size and material for an improved finish and extended bit life. (Fig. 16} Fig. 16 Speed changes are made starting at "1" and rotating the Speed Control Dial to the "LEFT" to increase the speed, and to the "RIGHT" to decrease the speed as indicated on the Dial, numbered 1 through 6. NOTE: The speed may be changed while the router is "ON", but not if the cutter bit is in the workpiece.
The speed charts the speed setting through operator manufacturers of on the preceding page indicate the relationship between and the cutting application. Exact settings are determined experience and preference, and also by recommendations cutter bits. by ELECTRONIC FEEDBACK CIRCUITRY The router electronic feedback circuitry monitors and adjusts power to maintain the desired speed for consistent performance and control, providing constant speed under load for a high-quality finish in all materials.
EDGE ROUTING 1. (Figs. 17 and 17a) Fig. 17a With the depth-of-cut set, place the router on the edge of workpiece, making sure that the cutter does not contact the workpiece. (With the plunge base, lock the plunge action in the DOWN position, ready to cut). 2. Have an edge guide (or a board or a metal straightedge) clamped in place to help guide router base when making the edge cut. 3. Turn the router "ON," and allow the router motor to reach the selected speed. 4.
4. When the cut is complete, turn the router motor "OFF" and allow the cutter bit come to a complete stop before removing it from the workpiece. 5. Unplug the router from power source, place the router upside down on the worktable, and inspect the finished cut in the workpiece. WARNING:Always securely clamp your workpiece and keep a firm grip on the router base with both hands at all times.
FREEHAND ROUTING WITH THE FIXED BASE (Fig. 21) _, WARNING: Do not use large cutter bits for freehand routing. Using large cutter bits when freehand routing could cause loss of control or create other hazardous conditions Fig. 21 that could result in personal injury. If using a router table, large bits should be used for edging only. _'-- When used freehand, the router becomes a flexible and versatile tool. This flexibility makes it possible to easily rout signs, relief sculptures, etc.
Top Edge Shaping 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-in. thick uncut portion at the bottom), the pilot can ride against the uncut portion, which serves to guide it (Fig. 22). Fig.
possibly resulting in personal injury. When "Climb-Cutting" is required (e.g., backing around a corner), exercise extreme caution to maintain control of the router. The high speed of the cutter bit during a proper feeding operation (left to right), results in very little kickback under normal conditions. However, if the cutter bit strikes a knot, an area of hard grain, or a foreign object, "Kickback" may result.
RATE OF FEED (Figs. 25 and 25a) 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. FEEDING TOO QUICKLY (Fig. 25} Fig.
CHIP SHIELDS (Figs. 26 and 26a) _1, WARNING: Always wear eye protection. The chip shields are not intended guards. as safety To remove the chip shield from the fixed base, press inward on the tabs until the chip shield releases from the base and then remove the chip shield. To attach, place the chip shield back in position and flex the sides while pushing the shield in until it snaps back into place (Fig. 26). The chip shield on the plunge base is held in position with a screw.
DUST COLLECTION WITH VACUUM PORT (Figs. 27 and 27a) Two vacuum ports are included with the router bases. Each adapter is sized to accept a 1-1/4-in. vac hose adapter, sold separately. ATTACH THE VACUUM FIXED BASE (Fig. 27) Fig. 27 PORT ONTO THE To attach the vacuum port onto the fixed base, align the two tabs on the port with the two slots on the port at back of the base, and secure it by turning it clockwise (Fig. 27a). ATTACH THE VACUUM PLUNGE BASE (Fig.
Fixed Base Router Fig. 28a When using either the fixed base to attach the router to the router table, the bit depth can be adjusted by turning the Micro-adjustment Dial clockwise or counterclockwise with the wrench supplied. (Fig. 28a and Fig. 28b). The depth of the cut can be read on the scale dial. Each mark on the scale indicates a 1/64-in. change in depth setting. 1. Turn off the router. 2. Loosen the router motor clamp. 3. Insert the wrench into the adjusting hole on the tabletop.
