• CHECK DAMAGED PARTS. Before further use of the tool, a
guard or other part that is damaged should be carefully checked
to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving
parts, breakage of parts, mounting, and any other conditions that
may affect its operation. A guard or other part that is defective
should be properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this instruction
manual. Have defective switches replaced by authorized service
center. Do not use tool if switch does not turn it on and off.
• DO NOT OPERATE portable electric tools near flammable liquids
or in gaseous or explosive atmospheres. Motors in these tools
normally spark, and the sparks might ignite fumes.
• CAUTION: When drilling or driving into walls, floors or wherever
live electrical wires may be encountered, DO NOT TOUCH ANY
METAL PARTS OF THE TOOLS! Hold the tool only by insulated
grasping surfaces to prevent electric shock if you drive into a live
wire.

Operating Rules for Nibblers
1. Always wear safety glasses and protective gloves.
2. Wear safety shoes to protect your feet from sharp metal debris on
floor.
3. Cut material at or below rated capacity. Remember, material
thickness increases as gauge number decreases (14 gauge is
thicker than 16 gauge). 14 gauge thickness is .075" (1,9 mm); 16
gauge is .060" (1,5 mm).
4. Keep all screws tight. Periodically check them for loosening.
5. Unplug tool before making any adjustments.
6. Do not put anything into a motor housing opening.
7. Keep tool clean. Blow off any metal debris and dirt from tool.
8. Firmly secure the piece of metal to be cut to prevent movement
during cutting.
PADDLE SWITCH
To start the tool, depress the paddle switch. To turn the tool off,
release the paddle. The switch can be locked on be engaging the
lock button located near the rear of the tool while holding the paddle
depressed. Always be sure that the tool is not locked on before
plugging it in. To turn the tool off when it is locked on, squeeze and
release the paddle once.
Operation
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY
BEFORE MAKING ANY ADJUSTMENTS. Always wear safety
glasses and protective gloves.
Lubricate surface of material with oil. The profile nibbler is designed
to cut corrugated, flat, and box steel forms.
The tool is factory assembled with the punch oriented forward for
cutting flat and shallow corrugated material. To cut deeper corrugated
metals and box sections, rotate the head 90˚ to either side to use tool
sideways.
The shoe can be aligned in three positions: left, forward, and right.
(See Figure 2).
To rotate the head, loosen the set screw. Turn the head in the desired
direction. NOTE: Do not rotate the head in a complete circle as this
will change the punch engagement in the die.
Rotate the shoe and turn the set screw in until you feel the set screw
engage a recess in the shoe. Tighten the set screw firmly.
Periodically recheck this screw for tightness.
Sharpening Punches
Never cut with a blunt, dull punch or die. Punches can be sharpened
