PNEUMATIC NOTCHING TOOL OPERATIONS´ MANUAL
The depth of the notches has to be adapted to the sheet metal thickness. This can be done by regulating
the M8 screw at the tie bolt which is seated at the front of the cutting head. The notches must not be deeper
than the sheet metal thickness, otherwise the sealing lip of the flange will not work properly. Please read the
following instructions carefully before using the notching tool.
OPERATING INSTRUCTIONS
Connection:
Take the tool out of the package and connect it to a compressed-air supply. For a longer live of the pneu-
matic notching tool we recommend to install a compressed-air conditioner (filter and mist oiler) in the com-
pressed-air piping as it is usually done for pneumatic tools. This tool has been designed to work with an
air-pressure of 6,5 bar. By using this tool with higher pressure you run the risk of damaging it. If the air
pressure is higher than 6 bar a pressure reducer must be installed. It has to be regulated for a maximum
pressure of 6,5 bar.
Operation:
You should first check if the correct stopping faces are installed. If not, unscrew the two screws which fix the
stopping faces on the cutting head. Take the correct stopping faces from the hopper on the end cover of the
tool (no. 13 on the enclosed drawing) and install them on the cutting head. The other stopping faces should
be replaced immediately in the hopper of the end cover, so they will not get lost.
Distance from the notches to the end of the duct (stopping face):
Flange Ring Duct-Ø Stopping Face
AF and BF 20 - 45 200 - 450 mm 7 mm
AF and BF 50 - 90 500 - 900 mm 9 mm
AF and BF 100 - 160 1000 - 1600 mm 15 mm (no stopping face used)
The depth of 15 mm is reached
when no stopping face is installed!
Take a piece of sheet metal to test the notches. The thickness of the sheet metal should be the same as the
thickness of the duct wall in which you want to make the notches. Hold the notching tool as shown hereaf-
