2. INTRODUCTION
Composite cover moulded around lightweight aluminium alloy housing reduces effects of chill on operator's hands and provides added control.
Air motor with quality bearings for smooth and powerful operation. Exhaust outlet adjusts 360°, keeping airflow away from operator. Suitable for
cutting intricate shapes in steel up to 1.5mm thick. Punch and die may be rotated through 360° to aid access and obtain maximum consumable
life.

4. AIR SUPPLY
NOTE:
The recommended air system is shown in fig.1.
Ensure that the air pressure is set correctly (90psi).
9
WARNING! Ensure that the air supply is clean and does not exceed 90psi. Too high an air pressure and/or unclean air will shorten the
‰
life of the nibbler due to accelerated wear, and may cause damage and/or personal injury.
Drain the compressor air tank daily. Water in the air line will damage the riveter.
9
Clean the compressor air inlet filter screen weekly.
9
Line pressure should be increased to compensate for unusually long air hoses (over 8 metres).
9
The minimum hose bore should be 10mm and fittings must have the same inside dimensions.
9
Keep hoses away from heat, oil and sharp edges.
9
Check hoses for wear, and make certain that all connections are secure.

5. OPERATION
NOTE:
Numbers refer to attached parts list.
WARNING! Ensure you read, understand and apply the Section 1 safety instructions. This tool is designed for nibbling
‰
sheet metal, primarily in workshops and garages. We do not recommend it for any other use or materials.
5.1.
CHANGING THE PUNCH AND/OR DIE
5.1.1.
Disconnect nibbling tool from the air line.
5.1.2.
Note the orientation of the die Ø7 hole revealing the waisted part of the punch. This hole faces the feed direction of the nibbler.
5.1.3.
Grip the nibbler head (37) in a soft jaw vice.
5.1.4.
With a 28mm A/F spanner undo the barrel nut (item 44).
5.1.5.
Remove the die, which has four grooves in the mounting flange. These grooves enable four nibbler positions at 90° intervals.
5.1.6.
Remove the punch by unscrewing the set screw (42) with a 9mm A/F spanner.
5.1.7.
Inspect the punch and die for wear, replace or renew by reversing removal procedure.
5.1.8.
Apply grease liberally to both punch and die when fitting and anticipate the nibbling direction.
