General Safety Rules for Bench Top Tools

Work Area

●Keep work area clean and well lit. Cluttered benches and dark areas invite accidents.

●Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

●Keep bystanders, children and visitors away while operating a power tool. Distractions can cause you to lose control.

●Store idle tools out of reach of children and other untrained persons. Tools are danger- ous in the hands of untrained users.

●Do not leave tool running unattended, turn power off. Do not leave tool until it comes to a complete stop.

●MAKE WORKSHOP CHILDPROOF with pad lock, master switches, or by removing starter keys.

Electrical Safety

●Before plugging in the tool, be certain the outlet voltage supplied is compatible with the voltage marked on the nameplate within 10%. An outlet voltage incompatible with that specified on the nameplate can result in serious hazards and damage to the tool.

●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. Double insulation eliminates the need for the three wire grounded power cord and grounded power supply.

●Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrig- erators. There is an increased risk of electric shock if your body is grounded.

●Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

●Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

●When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.

Personal Safety

●Stay alert, watch what you are doing and use common sense when operating a power tool. A moment of inattention or use of drugs, alcohol or medication while operating power tools can be dangerous.

●Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. Roll long sleeves above elbows. Rubber gloves and non-skid footwear are recommended when working out- doors.

●Avoid accidental starting. Be sure switch is “OFF” before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch “ON” invites accidents.

●Remove adjusting keys or wrenches before turning the tool “ON”. A wrench or a key that is left attached to a rotating part of the tool will be thrown.

●Do not overreach, keep proper footing and balance at all times. Proper footing and bal- ance enables better control of the tool in unex- pected situations.

●Do not stand on tool or its stand. Serious injury may occur if the tool is tipped or if the cut- ting tool is accidentally contacted. Do not store materials on or near the tool such that it is nec- essary to stand on the tool or its stand to reach them.
