11. Do not exceed maximum air pressure of 160 PSI.
12. Avoid unintentional starting. Do not carry any air tool with your finger on the trigger, whether it is plugged in or not.
13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool when you are tired.
14. Check for damaged parts. Before using Filter/Regulator, any part that appears damaged should be carefully
