CHANGING PUNCHES AND DIES
Disconnect the plug from
the power source before
making any assembly, adjustments or
changing accessories
. Such preventive
safety measures reduce the risk of starting
the tool accidentally.
CHANGING DIES
1. Loosen retaining screw. This screw locks the
die in one position.
2. After loosening the retaining screw, unscrew
the sleeve nut with a 1 1/4" (32mm) spanner
wrench.
3. Remove the sleeve nut along with the die.
4. Lubricate the sleeve nut, and the die with a
light weight oil and reassemble in reverse
order.
CHANGING PUNCHES
1. Loosen retaining screw and unscrew sleeve
nut with a 1 1/4" (32mm) spanner wrench.
2. Remove the sleeve nut along with the die.
3. Unscrew the punch retaining nut, and slide
the punch from the gear housing.
4. Insert a new, well oiled punch, and
reassemble in reverse order.
CHANGING THE DIE POSITION
3-POSITION DIE
1. Loosen retaining screw and remove sleeve
nut along with die.
2. Rotate die to any one of the fixed positions in
the gear housing.
3. Reinstall sleeve nut, and tighten retaining
screw.
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.
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.
SLIDE "ON-OFF" SWITCH
The Tool is switched "ON" by the slide switch
located at the side of the motor housing.
TO TURN TOOL "ON": slide the switch
forward.
TO TURN TOOL "OFF": slide the switch
backward.
Start the tool before applying to work and let
the tool come to full speed before contacting
the workpiece. Lift the tool from the work
before releasing the switch. DO NOT turn the
switch “ON” and “OFF” while the tool is
under load; this will greatly decrease the
switch life.
