Warning
Wear eye protection.
Be sure keyed washer is directly under the spindle nut and the spindle nut is tight.
Feed the workpiece against the rotation of the cutter.
Do not use awkward hand positions.
Keep fingers away from the revolving cutter. Use fixtures when necessary.
Use the overhead guard when the adjustable fence is not in place.
• KEEP GUARDS IN PLACE and in working order.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit of checking to see that keys and
adjusting wrenches are removed from the machine before turning it on.
• KEEP THE WORK AREA CLEAN. Cluttered areas and benches invite accidents.
• DON’T USE 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 CHILDREN AWAY. All visitors should be kept a safe distance from the work area.
• MAKE THE WORKSHOP KIDPROOF with padlocks, master swatches, or by removing starter keys.
• DON’T FORCE THE MACHINE. It will do the job better and safer at the rate for which it was
designed.
• USE THE RIGHT MACHINE. Don’t force a machine or attachment to do a job for which it was not
designed.
• USE THE PROPER EXTENSION 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 machine will
draw. An undersized cord will cause a drop in the line voltage resulting in power loss and
overheating. The table below 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, 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 SAFETY 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 WORK. Use clamps or a vise to hold work when practical. It’s safer than using your hand
and it frees both hands to operate the tool.
• DON’T OVERREACH. 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.
• ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE SERVICING.
• REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure the switch is in the off position
before plugging in.
• USE RECOMMENDED ACCESSORIES. Consult the operator’s manual for recommended
accessories. The use of improper accessories may cause risk of injury to persons.
• NEVER STAND ON A MACHINE. Serious injury could occur if the machine tips or if the blade/cutter
is unintentionally contacted.
• CHECK DAMAGED PARTS. Before further use of the machine, 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.
• DIRECTION OF FEED. Feed work into the cutter against the direction of rotation of the cutter only.
• NEVER LEAVE THE MACHINE RUNNING UNATTENDED. TURN POWER OFF. Don’t leave the
machine until it comes to a complete stop.
• DO NOT OPERATE this machine while tired or under the influence of drugs, alcohol, or any medication.
