Important Safety Instructions
WARNING: When using electric tools, basic safety precautions
should always be followed to reduce risk of fire, electric shock,
and personal injury, including the following:
READ ALL INSTRUCTIONS
Double Insulation
Double insulated tools are constructed throughout with two separate
layers of electrical insulation or one double thickness of insulation
between you and the tool’s electrical system. Tools built with this
insulation system are not intended to be grounded. As a result, your
tool is equipped with a two prong plug which permits you to use
extension cords without concern for maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety
precautions when operating this tool. The insulation system is for
added protection against injury resulting from a possible electrical
insulation failure within the tool.
CAUTION: WHEN SERVICING USE ONLY IDENTICAL
REPLACEMENT PARTS. Repair or replace damaged cords.
Polarized Plugs
Polarized plugs (one blade is wider than the other) are used on
equipment to reduce the risk of electric shock. When provided, this
plug will fit in the polarized outlet only one way. If the plug does not fit
fully into the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install the proper outlet. Do not change the plug
in any way.
Safety Instructions For All Tools
•KEEP WORK AREA CLEAN. Cluttered areas and benches invite
injuries.
•CONSIDER WORK AREA ENVIRONMENT. Don’t expose power
tools to rain. Don’t use power tools in damp or wet locations. Keep
work area well lit. Do not use tool in presence of flammable liquids
or gases.

•GUARD AGAINST ELECTRIC SHOCK. Prevent body contact
with grounded surfaces. For example; pipes, radiators, ranges, and
refrigerator enclosures.
•KEEP CHILDREN AWAY. Do not let visitors contact tool or
extension cord. All visitors should be kept away from work area.
•STORE IDLE TOOLS. When not in use, tools should be stored in
dry, and high or locked-up place — out of reach of children.
•DON’T FORCE TOOL. It will do the job better and safer at the
rate for which it was intended.
•USE RIGHT TOOL. Don’t force small tool or attachment to do the
job of a heavy-duty tool. Don’t use tool for purpose not intended.
•DRESS PROPERLY. Do not wear loose clothing or jewelry. They
can be caught in moving parts. Rubber gloves and non-skid
footwear are recommended when working outdoors. Wear
protective hair covering to contain long hair.
•USE SAFETY GLASSES. Also use face or dust mask if operation
is dusty.
•DON’T ABUSE CORD. Never carry tool by cord or yank it to
disconnect from receptacle. Keep cord from heat, oil, and sharp
edges.
•SECURE WORK. Use clamps or a vise to hold work. It’s safer than
using your hand and it frees both hands to operate tool.
•DON’T OVERREACH. Keep proper footing and balance at all
times.
•MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for
better and safer performance. Follow instructions for lubricating
and changing accessories. Inspect tool cords periodically and if
damaged, have repaired by authorized service facility. Inspect
extension cords periodically and replace if damaged. Keep
handles dry, clean, and free from oil and grease.
•DISCONNECT OR LOCK OFF TOOLS when not in use, before
servicing, and when changing accessories, such as blades, bits,
cutters.
•REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of
checking to see that keys and adjusting wrenches are removed
from tool before turning it on.
•AVOID UNINTENTIONAL STARTING. Don’t carry tool with finger
on switch. Be sure switch is off when plugging in.
•EXTENSION CORDS. Use only 3-wire extension cords that have
3-prong grounding-type plugs and 3-pole receptacles that accept
the tool’s plug. Replace or repair damaged cords. Make sure your
extension cord is in good condition. When using an extension cord,
be sure to use one heavy enough to carry the current your product
will draw. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. The following table
shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage.
The smaller the gage number, the heavier the cord.

•OUTDOOR USE EXTENSION CORDS. When tool is used
outdoors, use only extension cords intended for use outdoors and
so marked.
•STAY ALERT. Watch what you are doing. Use common sense.
Do not operate tool when you are tired.
•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 damaged
should be properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this instruction

DIRECTION OF CUT

The nibbler cuts a slot in the work 6mm wide so remember to
compensate for this when marking out and calculating material
requirements.
When starting the cut from an edge, place the nibbler so the slot in the
die engages the work and the edge is against the punch, which is the
moving part when cutting (Figure 4).
Start the nibbler by depressing the paddle switch. Hold the body
parallel to the work surface.
Exert only enough forward pressure to start the nibbler cutting and
maintain this pressure. Extra pressure will not increase the rate of cut
as the amount of material removed at each cutting stroke is fixed and
the rate of cut is dependent only on the speed of the nibbler. The
cutting line of the work should be lightly coated with oil to lubricate the
punch and die while cutting.
NOTE: Punch and die should be lubricated by immersing in a good
quality cutting oil approximately every 30 feet of cutting.
When the cut is to be started or finished within the periphery of the
work, a 13mm (1/2") hole must first be drilled in the work at the start or
finish point. This enables the die to be entered or withdrawn as it is
larger in diameter than the slot being cut in the work (Figure 5).
Circular holes should be cut in the manner shown in Figure 6, starting
at the 13mm (1/2") diameter hole within the circle.
Punch and Die Replacement
After a period of cutting, the punch will become blunted and require
replacement. At the same time, check the die for sharpness and replace
if necessary.
To remove the die, release the knurled ring (Figure 7). Having removed
the die, rotate the motor by turning the armature fan, accessible through
the side cooling slot, until the punch retaining nut is clear of the face of
the gearbox. With the spanner provided, release this nut
counterclockwise and remove the punch, Figure 8. Assemble in reverse
order.

use. Tools should be relubricated regularly every 60 days to 6 months,
depending on usage. Tools used constantly on production or heavy-
duty jobs and tools exposed to heat may require more frequent
lubrication. This lubrication should only be attempted by trained power
tool repairmen such as those at DEWALT certified service centers.
Motor Brushes
When the brushes on this tool become worn out, the tool will
automatically stop and prevent damage to the motor. Brush
replacement should be performed by DEWALT service centers.
