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 (not included) to connect to the Air Inlet
(29) on the Handle (40) of the Jack. 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, and then to the Impact Wrench. See FIGURE 1.
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 150-200 PSI. Do not exceed the recom-
mended air pressure of 200 PSI.
3. Check the air connection for leaks. Disconnect from the air source.
