1. CAUTION: Always disconnect power cord before attempting adjustment or maintenance.
2. Shim stripper to 1/16 inch above metal thickness being cut. See table "A", (Figure 4.)
3. Tighten all screws and check punch and die clearance at least once daily.
4. Keep punch and die sharp and a spare in stock.
5. Turn nibbler on before engaging material.
6. When possible, spread a thin film of oil on surfaces being cut as this will greatly extend punch and die life.
7. Alwaysstopmachineimmediatelyifitshouldjam. Neverforcetool. Unplugtool.Backoutpunchbyinserting
screwdriver in operating slot at rear of motor and turning motor shaft counter clockwise.
8. Always let nibbler do the work as guiding tool is all that is necessary and forcing will only cause it to operate
improperly.
9. Only cut the gauge metal that is recommended or servicing and expensive part damage will occur.
10. Always observe lubrication instructions.
11 Always make frequent checks on motor brushes, replacing if worn.
12. Your KETT / FENWAY model "SUPER" motor body is provided with four 5/16 -18 tapped holes on a 3 inch
square bolt pattern. When bench mounted, your "SUPER" Nibbler becomes a handy tool for shaping small
metal parts up to 3/8 inch thick, which may be fed into punch by hand with ease.
