Irnportaret Safety Instructiores

_ WARNING: When using electric tools, basic safety precautions

should always be followed to reduce risk of fire, electric shock,
and personal inju_ including the following:

READ A££ INSTRUCTIONS

Double Iresulation

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 Instructieres For All Tools

* KEEP WORKAREA CLEAN. Cluttered areas and benches invite

injuries.

* CONSIDER WORKAREA ENVIRONMENT. Don't expose power

tools to rain. Don't use power tools in damp or wet locations. Keep
work area weft fit. 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. Aft 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 # was intended.

* USE RIGHT TOOL. Don't force smafl 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 # frees both hands to operate tool.

* DON'T OVERREACH. Keep proper footing and balance at aft

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.

o

AVOID UNINTENTIONAL STARTING. Don't carry tool with finger

on switch. Be sure switch is off when plugging in.

o

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, ff 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.

o

STAY ALERT. Watch what you are doing. Use common sense.
Do not operate tool when you are tired.

o

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

SAVE THESE INSTRUCTIONS

Motor

Your DEWALTtool is powered by a DEWALT built motor. Be sure your
power supply agrees with the nameplate marking. Voltage decrease of

more than 10% will cause loss of power and overheating. All DEWALT
tools are factory tested; if this tool does not operate, check the power
supply.

Switch

To start tool, depress the paddle switch (Figure 1). To turn the tool off,

release the paddle. The paddle switch can be locked on by engaging
the lock button located near the rear of the tool, while holding the paddle
depressed. Always be su rethat the tool is not locked on before plugging

in. To turn the tool off when it is locked on, squeeze and release the
paddle once.

Setting the Cutter

TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.

The cutter can be set to cut in any direction relative to the body. Release
the set screw in the knurled ring (Figure 2) with key provided and

unscrew the ring by rotating in a counterclockwise direction as viewed
from the cutter.

Loosen ring just enough to be able to rotate the die. Set the die so that
the connecting web (Figure 3) is on the opposite side of the direction of

cut. Fully tighten the knurled ring and lock by tightening the set screw.

Operation

NOTE: ALWAYS WEAR SAFETY GLASSES.

Make sure the knurled ring (Figure 2) is tight prior to use. Keep fingers
away from cutter and other moving parts.

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 inthe 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.

Cleaning

Blowing dust and grit out of the main housing by means of air hose is
recommended and may be done as often as dirt is seen collecting in

and around the ventilator vents. The motor should be running while air

is being blown into the air vents.

Lubrication

DEWALTtools are properly lubricated at the factory and are ready to

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 DEWALTcertified 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.

Accessories

Recommended accessories for use with your tool are available at extra
cost from your distributor or local service center.

A CAUTION: The use of any non-recommended accessory may be

hazardous.

Repairs

To assure product SAFETY and RELIABILITY, repairs, maintenance
and adjustment (including brush inspection and replacement) should

be performed by authorized service centers or other qualified service
organizations, always using identical replacement parts.

Three Year Limited Warranty

DEWALTwill repair, without charge, any defects due to faulty materials
or workmanship for three years from the date of purchase. This
