as soon as possible.
1. You will need to prepare a 1/4” air connector (not included) to connect to the Air Inlet
(29) on the Impact Wrench. First, wrap the 1/4” air connector with pipe thread seal tape
before threading it into the Air Inlet (29). Connect the 3/8” ID Air Source Hose to a quick
connect coupler (not included), 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 to 90 PSI. Do not exceed the recommended air
pressure of 90 PSI.
3. Check the air connection for leaks. Disconnect from the air source.
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.
