GENERAL SAFETY RULES
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.
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.

24. THE DUST GENERATED by certain woods and wood
products can be injurious to your health. Always operate
machinery in well ventilated areas and provide for proper
dust removal. Use wood dust collection systems whenever
possible.
25.
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 paints,
· crystalline silica from bricks and cement and other
masonry products, and
· arsenic and chromium from chemically-treated lumber.
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, such as those
dust masks that are specially designed to filter out
microscopic particles.
SAVE THESE INSTRUCTIONS.
Refer to them often and use them to instruct others.
