Before running the nibbler, inspect the punch and die for excessive wear, and replace if nec- essary.
Do not exceed recommended capacities for this nibbler. Premature punch and die failure will occur when the nibbler is under- or
•Never start the nibbler with the punch and die in contact with the material being cut.
For clean and fast cuts, hold the nibbler so that the cutting head is at a right angle to the cutting path, with the body of the tool parallel to the corrugations. Move the cutting head in and out of the corrugations, constantly keeping the head at a right angle to the material being cut.
Feed the nibbler into the work with a minimum of pressure. Let the nibbler do the work. If the nibbler doesn’t cut correctly, check for a dull punch or die. Dulling will be apparent as more pressure is required to feed the nibbler into the material. Burrs will also show along the cut edge. A harder material will dull the punch and die faster than a soft material.
Always direct the cord toward the rear, and away from the nibbler. Keep it away from sharp edges.
Secure or clamp small workpieces to be cut to prevent slippage.
Always use recommended lubricant for the material being cut. Lack of lubricant will shorten punch and die life.

Nibbling to a Scribed Line
or with a Template
Cuts may be executed easily by guiding the nibbler along a template or a straight edge.
A preboring of 21mm (.827") diameter is re- quired for internal
When cutting, guide the unit with a slight thrust in the cutting direction. Cutting takes place during the downward movement of the punch. The chips are ejected downward through the knurled nut 9.
Rotating the Die holder
By rotating the die holder 6, cutting can be preformed at a right angle to the forward axis of the machine. Loosen the winged screw 2 and turn the die holder 6 (including the die 7 and knurled nut 9), to the right or left by 90°.
Tool Tips
The corrugated nibbler is especially designed for working with corrugated sheets of both trapezoidal and rectangular profiles.
Always use both hands to guide the nibbler.
Do not use force; this will lead to premature die and punch wear.
Before running the nibbler, be sure the punch and die are properly lubricated. See "Punch and Die Lubrication" section.
Never start the nibbler with the punch and die in contact with the material being cut.
Always be sure material is resting on lower die during operation.
Changing Punches and Dies
CAUTION! Unplug nibbler before changing punches and dies.
Replacing the punch
Loosen the winged screw 2 and pull the die holder 6 (including the die 7 and knurled nut 9) out of the housing 3. Slide the punch 4 sideways out of the groove and remove downward.
Oil the new punch well, insert into the groove and center.
