2). TO LOCK SWITCH ON: Squeeze trigger, depress button and release trigger. TO UNLOCK THE SWITCH: Squeeze trigger and release it without depressing the “Lock- ON” button. !WARNING If the “Lock-ON” button is continuously being depressed, the trigger cannot be released. On models 1617 & 1618 hold the tool with both hands while starting the tool, since torque from the motor can cause the tool to twist. SOFT START FEATURE (Models 1617EVS & 1618EVS only) Electronic feedback control minimizes torque twist customary in larger routers by limiting the speed at which motor starts. ELECTRONIC VARIABLE SPEED CONTROL (Models 1617EVS & 1618EVS only) The electronic speed control feature allows motor speed to be matched to cutter size and material hardness for improved finish, extended bit life, and higher performance. Speed changes are achieved by rotating Control Dial RIGHT to increase speed, LEFT to decrease as indicated on housing (Fig. 1). Speed may be changed while tool is on. The reference numbers on the dial facilitate resetting control to desired speed. The speed chart indicates the relationship between settings and application, exact settings are determined by operator experience and preference. The bit manufacturer may also have a speed recommendation.

Therefore, the most efficient cut is made by feeding the router so that the bit turns into the work, not away. Figure 15 shows proper feed for various cuts. How fast you feed depends on the hardness of the material and the size of the cut. For some materials, it is best to make several cuts of increasing depth. If the router is hard to control, heats up, runs very slowly or leaves an imperfect cut, consider these causes: 1. Wrong direction of feed — hard to control. 2. Feeding too fast — overloads motor. 3. Dull bit — overloads motor. 4. Cut is too large for one pass — overloads motor. 5. Feeding too slow — leaves friction burns on work. Feed smoothly and steadily (do not force). You will soon learn how the router sounds and feels when it is working best. GUIDING THE ROUTER The router can be guided through the work in any of several ways. The method you use depends, of course, on the demands of the particular job and on convenience. For routing operations such as grooving or dadoing, it is often necessary to guide the tool in a line parallel to a straight edge. One method of obtaining a straight cut is to securely clamp a board or other straightedge to the work surface, and guide the edge of the router sub-base along this path (Fig. 16). FIG. 15 BIT WORK DIRECTION OF ROUTER FEED START HERE RATE OF FEED When routing or doing related work in wood and plastics, the best finishes will result if the depth of cut and feed rate are regulated to keep the motor operating at high speed. Feed the router at a moderate rate. Soft materials require a faster feed rate than hard materials. The router may stall if improperly used or overloaded. Reduce the feed rate to prevent possible damage to the tool. Always be sure the collet chuck is tightened securely before use. Always use router bits with the shortest cutting length necessary to produce the desired cut. This will minimize router bit run- out and chatter.

Its sub-base is precisely centered at the factory. This positions the bit at the center of the sub-base and optional templet guides. Precision centering allows you to closely follow jigs such as straight guides, templets, and dovetail fixtures without worrying about bit walk-off from the intended cut line for any reason, including the orientation of t...
