GENERAL SAFETY RULES

for all Power Tools

Work Area

• KEEP WORK AREAS CLEAN. Cluttered
areas and benches invite accidents.

• AVOID DANGEROUS ENVIRONMENT.
Don’t use power tools in damp or wet locations.
Do not expose power tools to rain. Keep work
area well lit.

• AVOID GASEOUS AREAS. Do not oper­ate portable electric tools in explosive atmo­spheres in presence of flammable liquids or
gases. Motors in these tools normally spark,

BM 3609929430 4-04 4/22/04, 9:56 AM3

and the sparks might ignite fumes.

• KEEP CHILDREN AWAY. Do not let
visitors contact tool or extension cord. All
visitors should be kept away from work areas.

Personal Safety

• GUARD AGAINST ELECTRIC SHOCK.
Prevent body contact with grounded surfaces
such as pipes, radiators, ranges and refrigerator
enclosures. Rubber gloves and non-skid foot­wear are recommended when working out­doors, where damp or wet ground may be
encountered. A Ground Fault Circuit Inter­rupter protected power line must be used for
these conditions.

• DRESS PROPERLY. Do not wear loose
clothing or jewelry. They can be caught in
moving parts. Wear protective hair covering to
contain long hair.

• USE SAFETY EQUIPMENT. WEAR
SAFETY GOGGLES or glasses with side
shields. Wear hearing protection during ex-

tended use of power tools and dust mask for
dusty operations.

• STAY ALERT. USE COMMON SENSE.
Watch what you are doing. Do not operate tool
when you are tired or under influence of drugs.

•

REMOVE ADJUSTING KEYS AND
WRENCHES.
keys and adjusting wrenches are removed from
tool before turning it on.

• AVOID ACCIDENTAL STARTING. Don’t
carry plugged in tool with finger on switch. Be
sure the switch is OFF before being plugged in.

• DON’T OVERREACH. Keep proper foot­ing and balance at all times.

• BEFORE CONNECTING THE TOOL to a
power supply (receptacle, outlet, etc.) be sure
the voltage supplied is the same as that speci­fied on the tool’s nameplate. A power supply
with voltage greater than that specified for the
tool can result in serious injury to the user - as
well as damage to the tool. If in doubt, DO NOT
PLUG IN THE TOOL. Using a power supply
with voltage less than the nameplate rating is
harmful to the motor.

“Volts AC” designated tools are for Alternating
Current 50-60 Hz only. “Volts DC” designated
tools are for Direct Current. Do not use AC
designated tools with DC power supply. Do not
use

electronic speed controlled tools with DC

power supply.

Tool Use and Care

• DON’T FORCE TOOL. It will do the job
better and safer at the rate for which it was
designed.

• 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 - for
example; don’t use a circular saw for cutting
tree limbs or logs.

• SECURE WORK. Use clamps or a vise to
hold work. It’s safer than using your hand and
it frees both hands to operate the tool.

• DON’T ABUSE CORD. Never carry tool by
cord or yank it to disconnect from receptacle.
Keep cord from heat, oil, and sharp edges.
Always keep cord away from the spinning
blade, bits or any other moving part while the
tool is in use.

• OUTDOOR USE EXTENSION CORDS.

When tool is used outdoors, use only extension
cords suitable for use outdoors and marked with
suffix W-A (for UL), or W (for CSA). Refer to
section “Extension Cords”, for proper cord use.

• DISCONNECT TOOLS. When not in use,
before servicing, or when changing blades,
bits, cutters, etc.

• STORE IDLE TOOLS. When not in use,
tools should be stored in dry, high or locked up
place - out of the reach of children.

• DO NOT ALTER OR MISUSE TOOL.
These tools are precision built. Any alterations
or modifications not specified is misuse and
may result in a dangerous condition.

• THE USE OF ANY ACCESSORIES not
specified in this manual may create a hazard.

• 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.

• 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 promptly
and properly repaired or replaced. Have defec­tive switches replaced. Do not use tool if switch
does not turn it on or off.

• ALL REPAIRS, ELECTRICAL OR ME­CHANICAL, should be attempted only by
trained repairmen. Contact the nearest Bosch
Factory Service Center, or Bosch Authorized
Service Center or other competent repair cen­ter. Use only Bosch replacement parts, any
other may create a hazard.

Safety Rules for Nibblers

BM 3609929430 4-04 4/22/04, 9:56 AM4

• Wear leather gloves to protect hands from
sharp metal edges and safety shoes to protect
feet from sharp metal pieces.

• Periodically check tool fasteners for loose­ness, tighten as required.

• Do not cut material greater than the rated
capacity of the nibbler.

• Secure the material being cut. Never hold
small pieces in your hand or across legs.

• Do not use dull or damaged punch and dies or
accessories not intended for a nibbler. Replace
worn punches and dies immediately.

• Do not touch punch and die during use of the
nibbler.

• Never place the tool down until the punch has
come to a complete stop.

Some dust created by

power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive
harm. Some examples of these chemicals
are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and
other masonry products, and

• Arsenic and chromium from chemically
treated lumber.

Your risk from these exposures varies, de­pending on how often you do this type of work.
To reduce your exposure to these chemicals:
work in a well ventilated area, and work with
approved safety equipment, such as those dust
masks that are specially designed to filter out
microscopic particles.

a qualified service technician. WHEN SER­VICE IS REQUIRED USE ONLY IDENTI­CAL REPLACEMENT PARTS.

POLARIZED PLUGS: If your tool is equipped
with a polarized plug (one blade is wider than
the other), this plug will fit in a polarized outlet
only one way. If the plug does not fit fully in the
outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install the
proper outlet. To reduce the risk of electric
shock do not change the plug in any way.

Extension Cords

• Replace damaged cords immediately. Use of
damaged cords can shock, burn or electrocute.

• If an extension cord is necessary, a cord with
adequate size conductors should be used to
prevent excessive voltage drop, loss of power
or overheating. The table below shows the
correct size to use, depending on cord length
and amperage rating on the tool’s nameplate. If
in doubt, use the next heavier gauge. Always
use U.L. and CSA listed extension cords.

Double Insulated Tools

• Double Insulation is a design concept
used in electric power tools which eliminates

the need for the three wire grounded power cord
and grounded power supply system. It is a
recognized and approved system by
Underwriter’s Laboratories, CSA and Federal
OSHA authorities.

IMPORTANT: Servicing of a tool with

double insulation requires care and knowledge
of the system and should be performed only by

Operating the Tool

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 1 in the “OFF” posi­tion, become familiar with handling the nibbler
and learning the location of its parts.

5

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.

Paddle Switch with “Lock-ON” feature

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 automati­cally.

The “Lock-ON” feature, incorporated into the
paddle switch, is a convenience for long opera­tions.

TO LOCK SWITCH “ON”: After switch has
been activated, PULL the front portion of the
paddle lever completely BACKWARD and
release pressure on the paddle lever.

TO SWITCH TOOL “OFF”: Squeeze the rear
portion of paddle lever and then release the

paddle lever. The switch is spring loaded and
will return to “OFF” position automatically.

Nibbling to a Scribed Line

or with a Template

Cuts may be executed easily by guiding the
nibbler along a template or a straight edge.
A preboring of 21mm (.827") diameter is re­quired for internal cut-outs.
When cutting, guide the unit with a slight thrust
in the cutting direction. Cutting takes place
during the downward movement of the punch.
The chips are ejected downward through the
knurled nut 9.

Rotating the Die holder

By rotating the die holder 6, cutting can be
preformed at a right angle to the forward axis of
the machine. Loosen the winged screw 2 and turn
the die holder 6 (including the die 7 and knurled
nut 9), to the right or left by 90°. Re-tighten the
winged screw 2. The winged screw must engage
one of the 3 holes in the die holder 6.

Tool Tips

The corrugated nibbler is especially designed
for working with corrugated sheets of both
trapezoidal and rectangular profiles.

Always use both hands to guide the nibbler.
Do not use force; this will lead to premature die

and punch wear.
Before running the nibbler, be sure the punch

and die are properly lubricated. See "Punch and
Die Lubrication" section.

Never start the nibbler with the punch and die in
contact with the material being cut.

Always be sure material is resting on lower die
during operation.

Changing Punches and Dies

CAUTION! Unplug nibbler before changing
punches and dies.

Replacing the punch

Loosen the winged screw 2 and pull the die
holder 6 (including the die 7 and knurled nut 9)
out of the housing 3. Slide the punch 4 sideways
out of the groove and remove downward.

Oil the new punch well, insert into the groove
and center.

6

BM 3609929430 4-04 4/22/04, 9:56 AM6

Slide the die holder 6 carefully over the punch
and into the housing 3. Re-tighten the winged
screw 2. The winged screw must engage one of
the holes in the die holder 6.

NOTE: The punch cannot be reground.

Replacing the Die

Unscrew the knurled nut 9 together with the
rubber ring 8 out of the die holder 6 and remove
the die 7. Remove any rust material or cutting
particles that may have collected in the die
holder 6.

Insert a new die 7 paying attention to the align­ment of the flat surface on the side. Firmly
tighten the knurled nut 9 against the resistance
of the rubber ring 8.

NOTE: The die cannot be reground.

Punch and Die Lubrication

Proper lubrication is essential to prolong punch
and die life, and is achieved by occasionally
fully submersing the punch and die in a small
container of the proper lubricant.

To further ensure a smooth cut and long punch
life, always lubricate the cutting path with cut­ting oil. When cutting steel or stainless steel,
lubricate path of cut before starting work. When
cutting aluminum, lubricate path of cut while
making the cut. Since the punch cuts on the
downstroke, the upper side of the cut should be
lubricated.

When cutting steel, use a cutting oil or an SAE
30 weight oil.

When cutting aluminum, a mixture of 7 parts
kerosene and 3 parts turpentine should be used.

Should punch jam, immediately switch off
nibbler, re-lubricate punch and die, and remove
tension from sheet.

WARNING! The use of any accessory or

attachment other than recommended in this
instruction manual or the BOSCH Catalog may
present a risk of personal injury.

mend that all tool service be performed at a
Bosch Factory Service Center.

Tool Lubrication

Your Bosch tool has been properly lubricated
and is ready for use. We recommend, that tools
with gears be regreased with a special gear
lubricant every time the brushes are changed.

Carbon Brushes

The brushes and commutator in your Bosch
tool have been engineered for many hours of
dependable service. To maintain peak effi­ciency of the motor, we recommend that every
two to six months the brushes be examined.
Only genuine Bosch replacement brushes spe­cially designed for your tool should be used.

Bearings

After about 300-400 hours of operation, or at
every second brush change, the bearings should
be replaced at a Bosch Factory Service Center.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating and
motor failure.

Cleaning

WARNING! To avoid accidents, always

disconnect the tool from the power supply
before cleaning or performing any maintenance.
The tool may be cleaned most effectively with
compressed air. Always wear safety goggles
when cleaning tools with compressed air.

Ventilation openings and switch levers must be
kept clean and free of foreign matter. Do not
attempt to clean by inserting pointed objects
through openings.

CAUTION! Certain cleaning agents and

solvents damage plastic parts. Some of these
are: gasoline, carbon tetrachloride, chlorinated
cleaning solvents, ammonia and household
detergents that contain ammonia.

Maintenance and Service

WARNING! Preventive maintenance per-

formed by unauthorized personnel may result
in misplacing of internal wires and components
which could cause serious hazard. We recom-
