Your risk from these exposures 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, always wear MSHA/NIOSH
approved, properly fitting face mask or respirator when using such tools.
GENERAL SAFETY RULES
READ AND UNDERSTAND ALL WARNINGS AND OPERATING INSTRUCTIONS BEFORE
USING THIS EQUIPMENT. Failure to follow all instructions listed below, may result in electric shock,
fire, and/or serious personal injury or property damage.
IMPORTANT SAFETY INSTRUCTIONS
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there
are certain hazards involved with the operation of the product. Using the machine with respect and caution will
considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored,
personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards,
goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make
up for poor judgment, carelessness or inattention. Always use common sense
and exercise caution
in the workshop.
If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your
personal safety is your responsibility. For additional information please visit our website www
.deltamachinery.com.
This machine was designed for certain applications only. Delta Machinery strongly recommends that
this machine not be modified and/or used for any application other than that for which it was designed. If you have any
questions relative to a particular application, DO NOT use the machine until you have first contacted Delta to determine
if it can or should be performed on the product.

Your new Compound Miter Saw is DOUBLE-INSULATED to give you added safety. As a result, this saw is equipped
with a two-prong plug which permits you to use any conventional 120 volt electrical outlet with concern for maintaining
a ground connection.
Before connecting the motor to the power source, confirm that the electric current is 120 volts, and that all connections
are making good contact. NOTE: Running the saw on low voltage will damage the motor.
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
Many Delta tools will operate on either D.C., or single phase 25 to 60 cycle A.C. current and voltage within plus or minus
5 percent of that shown on the specification plate of the tool. Several models, however, are designed for A.C. current
only. Refer to the specification plate on your tool for proper voltage and current rating.
