Operation
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 1/4” air connector (sold separately) to connect to the Air
Inlet (#1). First, wrap the 1/4” air connector (not included) with pipe thread seal tape before
connecting to a Air Source Hose (not included).
2. Attach air hose to the Air Inlet (#1) on 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.
3. Set the air pressure on your compressor to 90 PSI. Do not exceed the maximum air
pressure of 90 PSI.
4. Check the air connection for leaks.
