AIR INPUT CONNECTIONS

Supply the PRO-CUT 60 with clean compressed air or nitrogen.

•Supply pressure must be between 70 psi and 120 psi (482 kPa and 827 kPa).

•Flow rate should be approximately 4.7 cfm (133 I/min.).

NOTE: Oil in the air supply to the PRO-CUT 60 can cause severe problems. Use only a clean air supply.

1.Connect the air supply to the PRO-CUT 60 regulator.

a.Remove the plastic thread protector from the machine's regulator input port located on the back of the machine. Refer to figure A.1.

-The input port is a 1/4" (6.3mm) NPT thread.

b.Connect the air supply to the machine reg- ulator with an appropriate gas connection fitting. Sealing the connection with Teflon tape is recommended.

2.Tighten the air fitting connection to prevent leakage.

-Do not overtighten.

NOTE: When using nitrogen gas from a cylinder, the cylinder must have a pressure regulator.

•Maximum psi from nitrogen gas cylinder to PRO-CUT 60 regulator should never exceed 120 psi (827 kPa).

•Install a hose between the nitrogen gas cylinder regulator and the PRO-CUT 60 regulator's gas inlet.

WARNING

CYLINDER could explode if damaged.

•Keep cylinder upright and chained to a fixed support.

•Keep cylinder away from areas where it could be damaged.
