Carbon Brushes; Environmental Protection - Metabo Kn 6875 Instrucciones De Manejo

Apply a coating of oil to the cutting mark when
machining sheet steel and apply petroleum
when cutting sheet aluminium.
The punch (7) leaves behind a groove in the mate-
rial about 8 mm (5/16") wide. With the cutting
head, you can rotate the machine 360° in the
material at any position, which makes it possible to
cut right-angled exterior contours (with a radius of
0 mm). The smallest radius for interior cut-outs is
4 mm
(3/16").
8.5 Cuts to a template fixed on the
workpiece
Ensure that the template is thick enough for the
overall thickness of workpiece + template to reach
4-5.5 mm (.16 to .22 inches).
The template must be clamped at a distance of
2.5 mm (.10 inches) from the contour you wish to
cut.
Guide the machine with the edge of the punch
guide (6) always resting on the template.
9 Maintenance
Pull the plug out of the plug socket before
any adjustments or servicing are performed.
9.1 Re-sharpening and replacing the punch
To remove the punch (7), loosen the grub screw
(3), pull the punch guide (6) from the housing (5)
and unscrew the punch (7) from the conrod bolt.
To re-sharpen the punch (7), grind the end face of
the punch flat (allow the grinding surface to cool!).
Whet the cutting edge slightly using an oil stone.
Replacing the punch, see Section 10 (Accesso-
ries).
Screw the punch (7) into the conrod bolt (so that
the conrod bolt can still be moved slightly in the
conrod). Slide the punch guide (6) over the punch
(7) and into the housing (5).
Check the dipping depth of the punch (7)
(see Section 8.2). and adjust if necessary
(see Section 8.2).
Secure by tightening the grub screw (3)
9.2 Replacing the die
Replace the die (8) if it becomes blunt.
Open up the spring (9) slightly and remove.
Remove the straight pin that secures the die (8)
and pull out the die (8).
Replacing the die, see Section 10 (Accessories).
Secure the die with the new straight pin supplied.
Place the spring (9) back in position and turn so
that it covers the straight pin.
