tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. 2. Double 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.
TOOL USE AND CARE 1. Use clamps (not included) or other practical ways to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. 2. Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. 3. Do not use the power tool if the Power Switch does not turn it on or off.
3. Under no circumstance is the Router base ever to be removed from the Router in order to use bits that are too large to use with the base assembly attached. Removal of the Router base, and using the Router “free hand” can lead to serious bodily injury. 4. Never touch the bit, collet, or any other moving parts while the Router is in operation. 5. Never lay the Router down until it has stopped rotating completely. 6.
18. Do not force the Router. This tool will do the work better and safer at the speed and capacity for which it was designed. 19. Always unplug the Router from its electrical outlet before performing any inspection, maintenance, or cleaning procedures. 20. Never leave the Router unattended while running. Turn power off if you have to leave the Router. 21. Before each use, check all nuts, bolts, and screws for tightness. Vibration during mixing may cause these to loosen. 22.
power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician. Grounded Tools: Tools with Three Prong Plugs Note: This product has a line cord with a 3-prong, grounded plug. 1. Tools marked with “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet.
5. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.) 6. If you are using an extension cord outdoors, make sure it is marked with the suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use. 7. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
