TOOL USE AND CARE

1.Do not force the compressor. Use the correct compressor for your application. The correct compressor will do the job better and safer at the rate for which it is designed. Never attempt to force the compressor to provide more pressure than it was designed for.

2.Do not use the compressor if the Power Switch does not turn it on or turn it off. Any compressor that cannot be controlled with the Power Switch is dangerous and must be repaired or replaced.

3.Disconnect the Power Cord Plug from the power source before making any adjustments, changing accessories, or storing the compressor. Such preventive safety measures reduce the risk of starting the compressor accidentally.

4.Keep idle compressors out of reach of children and other untrained persons. Compressors are dangerous in the hands of untrained users.
