The impact wrench MUST have 3-4 drops of air
tool oil directly dropped into the air fitting before
each use. For best results, use the automatic

with SAE#30 oil before use. Then check every 48
hours of use and refill as needed.
Note: The oil chamber is independent of the air
chamber and will not be serviced by the automatic
oiler.
