Warning
• KEEP GUARDS IN PLACE and in order.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form the habit of checking to see that keys and adjusting
wrenches are removed from the tool before turning it on.
• KEEP THE WORK AREA CLEAN. Cluttered areas and benches invite acci den ts.
• DO NOT US E IN A DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or expose
them to rain. Keep work area well lighted.
• KEEP CHILDRE N A WAY . All visitors should be kept safe distance from the work area.
• MAKE THE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.
• DON’T FORCE THE TOOL. It will do the job better and safer at the rate for which it was designed.
• USE THE RIGHT TOOL. Don’t force a tool or attachment to do a job for which it was not designed.
• USE THE PROPER EXTEN SI ON CORD. Make sure your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord
will cause a drop in the line voltage resulting in loss of power and overheating. For runs up to 25 feet, use a 16
AWG or larger gauge cord. For runs up to 50 feet, use a 16 AWG or larger cord. For runs up to 100 feet,
use a 14 AWG or larger cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the
heavier the cord.
• WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to
contain long hair.
• ALWAYS USE SAFET Y GLASSES. Also use face or dust masks if the cutting operation is dusty. Everyday
eyeglasses only have impact resistant lenses, they are NOT safety glasses.
• SECURE WO R K. Use clamps or a vise to hold the work when it’s practical. It’s safer than using your hand and it
frees both hands to operate the tool.
• DON’T OVE RREACH. Keep proper footing and balance at all times.
• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.
• DISCONNECT TOOLS before servicing; when changing accessories, such as blades, bits cutters, and the like.
• REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure the switch is in the off position before
plugging in the machine.
• USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended accessories. The use
of improper accessories may cause a risk of injury.
• NEVER STAND ON A TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally
contacted.
• CHECK DA MA GED PA RTS. Before further use of the tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly and perform its intended function. Check for alignment
of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect
its operation. A guard or other part that is damaged should be properly repaired or replaced.
• DIRECTI ON OF FEED. Feed work into a blade or cutter against the direction of rotation of the blade or cutter
only.
• NEVER LEAVE THE TOOL RUNNING UNATTENDED. TURN THE POWER OFF. Don’t leave the tool until it
comes to a complete stop.
• WARNING: Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
• Lead from lead based paint.
• Crystalline silica from bricks, cemen t and other masonry products.
• Arsenic and chromium from chemically treated lumber.
Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these
chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks
that are specifically designed to filter out microscopic particles.
