For best service you should incorporate an oiler, regulator, and inline filter, as shown in the diagram above. Hoses, couplers, oilers, regulators, and filters are all available at Harbor Freight Tools.
1.You will need to prepare a 1/2” air connector (not included) to connect to the Air Inlet (23) on the Impact Wrench. First, wrap the 1/2” air connector with pipe thread seal tape before threading it into the Air Inlet (23). Connect the 3/8” ID air source hose to a quick connect coupler, and then to the Impact Wrench.
Note: If you are not using an automatic oiler system, before operation, add a few drops of Pneumatic Tool Oil to the airline connection. Add a few drops more after each hour of continual use.
2.Set the air pressure on the regulator. Note: To achieve the maximum torque of 1450 Ft. Lbs., set the air pressure at 120 PSI. Never exceed 120 PSI.
3.Check the air connection for leaks. Disconnect from the air source.
