1. You will need to prepare a
1 /
4
” air connector (not included) to connect to the Inlet
(10) on the Die Grinder. First, wrap the 1 /
4

before threading it into the Inlet (10). Connect the 3 /

connect coupler (not included), and then to the Die Grinder.
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 maximum air
pressure of 90 PSI.
