What are the general safety rules for power tools?

Read and understand all instructions. Failure to follow all instructions may result in electric shock, fire, and/or serious personal injury. Keep the work area clean and well lit, and do not operate power tools in explosive atmospheres. Keep bystanders, children, and visitors away while operating a power tool. Double insulated tools are equipped with a polarized plug; do not change the plug in any way. Avoid body contact with grounded surfaces. Do not expose power tools to rain or wet conditions. Do not abuse the cord and replace damaged cords immediately. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. Stay alert, watch what you are doing, and use common sense when operating a power tool; do not use the tool while tired or under the influence of drugs, alcohol, or medication. Dress properly and keep hair, clothing, and gloves away from moving parts. Avoid accidental starting and be sure the switch is off before plugging in. Remove adjusting keys or wrenches before turning the tool on. Do not overreach and maintain proper footing and balance at all times. Use safety equipment, always wear eye protection. Use clamps or other practical ways to secure and support the workpiece to a stable platform. Do not force the tool, use the correct tool for the application. Do not use the tool if the switch does not turn it on or off. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Store idle tools out of reach of children and other untrained persons. Maintain tools with care and keep cutting tools sharp and clean. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation; if damaged, have the tool serviced before using. Use only accessories that are recommended by the manufacturer for the model. Tool service must be performed only by qualified repair personnel. When servicing a tool, use only identical replacement parts and follow instructions in the maintenance section of the manual.

What should I do to ensure my electrical safety when using power tools?

Double insulated tools have a polarized plug. 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. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. Do not expose power tools to rain or wet conditions. Never use the cord to carry the tools or pull the plug from an outlet, keep the cord away from heat, oil, sharp edges, or moving parts, and replace damaged cords immediately. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”.

What is the proper extension cord to use with power tools?

Make sure the extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current the product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating; if in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

What are the specific safety rules for sanders?

Do not let comfort or familiarity with the product replace strict adherence to sander safety rules. Hold the tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Always use safety glasses or goggles. Hold the tool firmly with both hands. Make sure the belt is not contacting the workpiece before the switch is turned on. Keep hands away from rotating parts. Do not leave the tool running and only operate the tool when hand-held. This tool has not been waterproofed, so do not use water on the workpiece surface. Ventilate the work area adequately when performing sanding operations. The use of this tool to sand some products, paints, and wood could expose the user to dust containing hazardous substances; use appropriate respiratory protection.

---

What could happen if I misuse the sander or fail to follow safety rules?

Serious personal injury may occur.

---

What do the symbols used for the tool mean?

V = volts A = amperes Hz = hertz = alternating current = Class II Construction m/s = meter per second ft/min = feet per minute

---

What should I check before adjusting or checking the function of the tool?

Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

---

What should I check before plugging in the tool?

Always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.
