9.Maintain tools with care. Keep tools clean for better and safer performance. Follow instructions for lubricating and changing accessories. Inspect tool cords and air hoses periodically and, if damaged, have them repaired by an authorized technician. The handles must be kept clean, dry, and free from oil and grease at all times.

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 before connecting it to the air source.

12.Avoid unintentional starting. Be sure the trigger is in the Off position when not in use and before attaching to the air source. Do not carry any tool with your finger on the trigger, whether it is attached to the air compressor 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. Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not use the tool if any trigger does not operate properly.

15.Replacement parts and accessories. When servicing, use only identical replacement parts. Use of any other parts will void the warranty. Only use accessories intended for use with this tool. Approved accessories are available from Harbor Freight Tools.

16.Do not operate tool if under the influence of alcohol or drugs. Read warning labels if taking prescription medicine to determine if your judgement or reflexes are impaired while taking drugs. If there is any doubt, do not operate the tool.

17.Use proper size and type extension cord. If an extension cord is required for the compressor, it must be of the proper size and type to supply the correct current to the compressor without heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the compressor. Check your compressor’s manual for the appropriate size cord.

18.Maintenance. For your safety, maintenance should be performed regularly by a qualified technician and the unit must be thoroughly cleaned out after every use.

Improper cleaning of the Spray Gun is a common reason for the Spray Gun to jam or not perform properly.

19.Compressed air only. Never use combustible gas as a power source. Never exceed the recommended operating pressure of the any of the parts (i.e. hoses, fittings, gun) of the Sprayer system.

20.Do not spray near open flames, pilot lights, stoves, heaters, the air compressor, or any other heat source. Most solvents and coatings are highly flammable, particularly when sprayed. Maintain a distance of at least 25 feet from the air compressor. If possible, locate the air compressor in a separate room. Do not smoke while spraying.
