Oil your air tools just before you go home at night. This will keep the internal parts lubricated as they sit idle over night. Chrome sockets should not be used on air impact tools for a number of reasons. Due to the hardness of the chrome socket it can shatter and cause injury.
This hardness can also cause the premature wearing of the anvil. The socket may get stuck on the anvil because the retaining ring on the anvil gets locked into the dimples on the socket. This can require you to pry the socket off causing damage to the retaining ring.
Always wear safety glasses or goggles

Remember to grease the threads of puller forcing screws. A dry thread can cause "Galling" which can damage pullers making them unusable. Here is a good example!
