8.Do not overreach. Keep proper footing and balance at all times. Do not reach over or across running machines or air hoses.

9.Maintain tools with care. Keep tools clean for better and safer performance. Follow instructions for lubricating and changing accessories.

10.Disconnect air supply. Disconnect air hose when not in use.

11.Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are removed from the tool or machine work surface before plugging it in.

12.Avoid unintentional starting. Be sure the switch is in the Off position when not in use and before plugging in. Do not carry any 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 any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function.

15.Guard against electric shock. Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures.

Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the tool. Check your compressor’s manual for the appropriate size cord.

19.Maintenance. For your safety, maintenance should be performed regularly by a qualified technician.
