3. Keep children away. Children must never be allowed in the work area. Do not let
them handle the Door Closer.

4. Store idle equipment. When not in use, products must be stored in a dry location to

5. Use the right product for the job. Do not attempt to force a small product to do the
work of a larger industrial product. There are certain applications for which this
product was designed. It will do the job better and more safely at the rate for which it
was intended. Do not modify this product and do not use this product for a purpose for
which it was not intended.

6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear

operation. Any part that is damaged should be properly repaired or replaced by a
