Any part that is damaged should be properly repaired or re- placed by a qualified technician. Do not use the tool if the trigger does not oper- ate properly. 15. Guard against electric shock. Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures. 16. Replacement parts and accessories. This product is to be repaired and ser- viced only by a qualified technician. When this product is serviced, only identical replacement parts should be used. 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. 17. 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. 18. Use proper size and type extension cord. If an extension cord is required, it must be of the proper size and type to supply the correct current to the compres- sor without heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the tool. Check your air compressor’s manual for the appropriate size cord. It is also possible that the use of an extension cord may cause your circuit breaker to trip or your panel fuse to break. If this happens, either use the compressor without an extension cord or find a larger amperage circuit to use. 19. Maintenance. The maintenance outlined in the maintenance section should be performed regularly. For your safety, this product should be serviced or repaired regularly only by a qualified technician. 20. Compressed air only. Never use combustible gas as a power source. 21. Do not load nails with the trigger or safety depressed. Unintentional firing may occur. Do not load nails when the air hose is connected to the tool. Always assume the tool contains fasteners. 22. Disconnect air supply before loading the Nailer. Before reloading (or making any adjustments to) the Nailer, make sure the compressed air is disconnected. 23. Fire fasteners into an appropriate work surface only. Do not attempt to fire fasteners into surfaces too hard to penetrate. Do not drive fasteners on top of other fasteners, or at too steep an angle. Fasteners can ricochet causing per- sonal injury. Never fire the Nailer into the air, or point it toward yourself or another
