3-11. Installing the air hoses

Connect the air hose from the compressor to the air unit underneath the work table.

 

 

1.

Turn the nut (1) at the end of the air hose, and then

 

 

 

 

 

connect the hose to the valve (2).

 

 

2.

Open the air cock (3) on the compressor.

Check that there is no air leaking from the valve

 

 

 

connection.

 

 

3.

Open the cock (3) by turning it in the direction of the

arrow.

(2) Closed

 

 

The meter needle will move clockwise.

Adjusting the air pressure

Set the air pressure for the knife pressure adjustment regulator (3) to the lowest pressure at which the knife can still cut the material. Set the standard air pressure for the main regulator (1) to 0.5 MPa.

To decrease the air pressure

1.Gently lift the knob (2) of the main regulator (1) and turn it in the direction of the arrow in the illustration. The pressure will increase when the knob (2) is turned clockwise.

2.Gently lift the knob (4) of the knife pressure adjustment regulator (3) and turn it in the direction of the arrow in the illustration.

The pressure will increase when the knob (4) is turned clockwise.

*The pressure for the knife pressure adjustment regulator (3) is adjusted to 0.3 MPa. Be careful not to increase this pressure needlessly, otherwise poor cutting performance or damage to the knife may result.

1.Close the cock (5). (The needle will remain at the high pressure position.)

2.Turn the knob screw (6) in the direction of the arrow in the illustration to loosen it. Make sure that you turn it in the correct direction.

The air will escape from the reservoir and the needle will drop.

3.Tighten the knob screw (6).

4.To reduce the air pressure, gently lift knob (2) or knob

(4) and turn it counterclockwise.

5.Open the cock (5). Air will enter the reservoir and the needle will move
