GENERAL POWER TOOL SAFETY WARNINGS _, WARNING: Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. • Know your power tool. Read the operator's manual carefully. Learn the applications, as well as the specific potential hazards related to this tool. Following this rule will reduce the risk of electric shock, fire or serious injury. • Save these instructions.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCl) protected supply. Use of a GFCI reduces the risk of electric shock. PERSONAL SAFETY Stay alert, watch what you are doing and use common sense when operating a power tool.
POWER TOOL USE AND CARE Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and more safely at the rate for which it was designed. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. Always check the tool for damaged parts before use.
SERVICE SAFETY • Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. If any part of this router is missing or should break, bend, or fail in any way; or should any electrical component fail to perform properly: shut off the power switch and remove the plug from the power source and have the missing, damaged, or failed parts replaced before resuming operation.
• Always keep the chip shield clean and in place. • Stay alert and clear the router cutter bit path of any obstructions before starting the motor. Keep cutting area clear of all foreign objects while the motor is running. • Inspect • Check • Make sure that the cutter bit is not in contact with the workpiece before the switch is turned on. The bit must always be running at full speed before contacting the workpiece.
• Only use router tables with on=board switch=controlled receptacles. Failure to use router tables with all the appropriate safety features could result in serious personal injury. • Disconnect adjustments • if you are changing a bit immediately after use, be careful not to touch the collet/nut or cutter bit with your hands or fingers. The heat buildup from cutting could cause severe burns. Always use the wrench provided. • Avoid "climb cutting;" see "Direction of Feed in" section in this manual.
3. Inspect the items carefully to make sure that no breakage or damage has occurred during shipping. If any of the items mentioned is missing, (refer to "PARTS LIST" illustration), return the router to your nearest Sears store to have the router replaced. ,_, WARNING: If any part is broken or missing, do not attempt to assemble the router, plug in the power cord, or operate the router until the broken or missing part is replaced. Failure to do so could result in possible serious injury.

Exact settings are determined by operator experience and reference, and also by recommendations made by manufacturers of cutter bits.
To be certain that your depth settings are correct, always make test cuts in scrap material similar to your workpiece before beginning the final cutting operation. Remember, knowing the right depth for each cut comes with routing experience.

NOTE: Making a single deep cut is never advisable. Smaller-diameter bits are easily broken by too much side thrust and torque. Larger bits will cause a rough cut and be difficult to guide and control. For these reasons, do not exceed 1/8in. depth of cut in a single pass. _, WARNING: Always securely clamp your workpiece in place, and keep a firm grip on the router base with both hands at all times. Failure to do so could result in loss of control causing possible serious personal injury.
FEEDING THE ROUTER (Fig. 16) The secrets to professional routing are a careful set-up for the cut, selecting the proper depth of cut, knowing how the cutter bit reacts in your workpiece, and the rate and direction of feed of the router. DIRECTION EXTERNAL Fig. 16 ROUTER FEED DIRECTION OF FEED-CUTS (Fig. 16) The cutter bit rotates clockwise. Feeding the bit from left to right will cause the bit to pull the ) router towards the workpiece ROUTER FEED DIRECTION (see Fig. 16).

by the sound of the motor. Its usual high-pitched whine will sound lower and stronger as it loses speed. Holding the router against the workpiece will also come more difficult. FEEDING TOO SLOWLY (Fig. 18a} When you feed the cutter bit too slowly, the rotating cutter bit does not cut into new wood rapidly enough to take a bite. Instead, it scrapes away sawdust-like particles.
TO ADJUST DEPTH WITH DEPTH=ADJUSTMENT WRENCH (Figs. 21, 21a) NOTE: The Depth-Adjustment Wrench supplied is used to adjust the depth when the router is fixed to the router table (Model No. 320.28180), sold separately (Fig. 21). _, WARNING: Fig. 21 Always read and follow all directions for mounting the router to a router table and for use of the router table.
