A licensed electrician must complete all connections to electrical 
power.

Before connecting to a power source, confirm that the electrical 
current of the power source is the same as the electrical system 
supplied with your machine. Ensure the machine is protected with 
an external over current protective device per your local regulating 
authorities. 

Machine must be properly grounded to prevent electric shock. 
Never connect the yellow/green wire to a live terminal.

Once connected to power source, terminals are electrified even 
while the power switch is off.

We have covered some basic electrical requirements for the safe 
installation of your machine. These requirements may not cover all 
installation requirements. You must confirm that your particular electrical 
configuration complies with all local codes. Ensure compliance by 
checking with your local municipality and a licensed electrician.

5.2 Air Supply Connection

Boring carriage adjustment and Quick-Release clamp operation are 
pneumatically controlled using the foot pedal. 

A ¼" N.P.T. inlet is supplied with the machine’s air fitter/regulator to 
connect the machine to the air supply. 

The air pressure regulator should be set to 90-100 psi. 

Regulating knob

Pressure gauge

To adjust the pressure:

1.  Pull up on the outer ring of the regulating knob.

2.  Turn the regulating knob counterclockwise to let air exhaust to a 

pressure level below the desired setting. 

3.  Turn the knob clockwise to slowly increase the pressure to the 

desired setting.
