CHANGING PUNCHES AND DIES
Disconnect the plug from
W RNING
the power source before
making any assembly, adjustments or
changing accessories. Such preventive
safety measures reduce the risk of starting
the tool accidentally.
REPLACING THE PUNCH
Loosen the winged screw and pull the die
holder (including the die and knurled nut) out
of the housing. Slide the punch sideways out
of the groove and remove downward.
Oil the new punch well, insert into the groove
and center.
Slide the die holder carefully over the punch
and into the housing. Re-tighten the winged
GENERAL INFORMATION
Following a few simple tips will reduce wear on
the tool and the chance of injury to the user.
With the tool unplugged from the power supply
and the ON/OFF Switch in the "OFF" position,
become familiar with handling the nibbler and
learning the location of its parts.
Before running the nibbler, inspect the punch
and die for excessive wear, and replace if
necessary.
Do not exceed recommended capacities for
this nibbler. Premature punch and die failure
will occur when the nibbler is under- or over-
gaged.
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.
Assembly
screw. The winged screw must engage one of
the holes in the die holder.
NOTE: The punch cannot be reground.
Unscrew the knurled nut together with the
rubber ring out of the die holder and remove
the die. Remove any rust material or cutting
particles that may have collected in the die
holder.
Insert a new die paying attention to the
alignment of the flat surface on the side. Firmly
tighten the knurled nut against the resistance
of the rubber ring.
NOTE: The die cannot be reground.
Operating Instructions
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.
The Paddle Switch enables the operator to
control the switch functions of "ON/OFF" and
"Lock-ON".
TO SWITCH TOOL "ON": Squeeze and hold
the paddle lever.
TO SWITCH TOOL "OFF": Release pressure
on the paddle lever. The switch is spring
loaded and will return to "OFF" position

The "Lock-ON" feature, incorporated into the

been activated, PULL the front portion of the
paddle lever completely BACKWARD and
release pressure on the paddle lever.
