RULES FOR SAFE OPERATION
Safe operation of this accessory requires that you read and
understand this operator's manual, the operator’s manual for
the table saw and all labels affixed to the tool.
READ ALL INSTRUCTIONS
■ KNOW YOUR ACCESSORY. Read the operator's manual
carefully. Learn the product's applications and limitations
as well as the specific potential hazards related to this
product.
■ KEEP THE WORK AREA CLEAN. Cluttered work areas
and work benches invite accidents. DO NOT leave tools
or pieces of wood on the saw while operating.
■ ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impact-resis-
tant lenses; they are NOT safety glasses.
The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols, and the explanations
with them, deserve your careful attention and understanding. The safety warnings do not by themselves eliminate any
danger. The instructions or warnings they give are not substitutes for proper accident prevention measures.
SYMBOL MEANING
■ DO NOT USE THIS PRODUCT WITH OTHER EQUIPMENT or for other purposes.
■ ALWAYS DISCONNECT THE SAW FROM THE POWER
SUPPLY BEFORE ASSEMBLING THIS KIT. Make sure
the switch is off when reconnecting the saw to a power
supply.
■ BEFORE MAKING A CUT, BE SURE ALL ADJUSTMENTS ARE SECURE.
■ SAVE THESE INSTRUCTIONS. Refer to them frequently
and use them to instruct other users. If you loan someone
this product, also loan these instructions.
SAFETY ALERT SYMBOL: Indicates danger, warning or caution. May be used in conjunction with other
symbols or pictographs.
DANGER: Failure to obey a safety warning will result in serious injury to yourself or to others. Always follow
the safety precautions to reduce the risk of fire, electric shock and personal injury.
WARNING: Failure to obey a safety warning can result in serious injury to yourself or to others. Always
follow the safety precautions to reduce the risk of fire, electric shock and personal injury.

The operation of any power tool can result in foreign objects being thrown into your eyes, which
can result in severe eye damage. Before beginning tool operation, always wear safety goggles

taking care not to drag your knuckles across the blade.
