Replacing Carbon Brushes; Optional Accessories - Makita JN3201 Instruction Manual

Punch & die service life
Replace or sharpen punch and die after cutting the
lengths indicated in the accompanying table. Their life,
of course, depends upon the thickness of materials cut
and lubrication conditions.
Punch Replace after 150 m of 3.2 mm steel sheet
Die Sharpen after 300 m of 3.2 mm steel sheet
006441
When cutting is poor even after replacing the punch,
sharpen the die. Grind down the dull edge shown in the
figure using a grinder. After rough-grinding the dull
portion, finish with a dressing stone. Stock removal
should be about 0.3 to 0.4 mm.
Fig.9
When installing ground die, a clearance of 3.5 to 4.0
mm should be obtained by attaching one or two of the
washer provided, as shown in the figure. Failure to have
the proper clearance will result in vibration during
cutting.

CAUTION:
Secure installing screws carefully when installing.

The die can be sharpened two times. After two
•
sharpenings, it should be replaced with new one.
