Work Area
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the
dust or fumes.
Keep by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Double Insulated tools are 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 a polarized outlet. Do
not change the plug in any way. Double
Insulation eliminates the need for the
three wire grounded power cord and
grounded power supply system. Before
plugging in the tool, be certain the outlet
voltage supplied is within the voltage marked
on the nameplate. Do not use “AC only”
rated tools with a DC power supply.
Avoid body contact with grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased
risk of electric shock if your body is
grounded. If operating the power tool in
damp locations is unavoidable, a Ground
Fault Circuit Interrupter must be used to
supply the power to your tool. Electrician’s
rubber gloves and footwear will further
enhance your personal safety.
Don't expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the
cord to carry the tools or pull the plug
from an outlet. Keep cord away from
heat, oil, sharp edges or moving parts.
Replace damaged cords immediately.
Damaged cords increase the risk of electric
shock.
When operating a power tool outside, use
an outdoor extension cord marked "W-A"
or "W." These cords are rated for outdoor
use and reduce the risk of electric shock.
Refer to “Recommended sizes of Extension
Cords” in the Accessory section of this
manual.
Personal Safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry,
or long hair can be caught in moving parts.
Keep handles dry, clean and free from oil
and grease.
Avoid accidental starting. Be sure switch
is “OFF” before plugging in. Carrying tools
with your finger on the switch or plugging in
tools that have the switch “ON” invites
accidents.
Remove adjusting keys or wrenches
before turning the tool “ON”. A wrench or
a key that is left attached to a rotating part
of the tool may result in personal injury.
Do not overreach. Keep proper footing
and balance at all times. Proper footing
and balance enables better control of the
tool in unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions.

Safety Rules for Shears
Tool Use and Care
Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
Do not force tool. Use the correct tool for
your application. The correct tool will do
the job better and safer at the rate for which
it is designed.
Do not use tool if switch does not turn it
“ON” or “OFF”. Any tool that cannot be
controlled with the switch is dangerous and
must be repaired.
Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally. Store
idle tools out of reach of children and
other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools, with sharp cutting edges are less likely
to bind and are easier to control. Any
alteration or modification is a misuse and
may result in a dangerous condition.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools. Develop
a periodic maintenance schedule for your
tool.
Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be
suitable for one tool,
may become hazardous
when used on another tool.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced or
pinched, safety guard return springs may be
improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk
of electric shock or injury. Certain cleaning
agents such as gasoline, carbon
tetrachloride, ammonia, etc. may damage
plastic parts.
Hold tools by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or it
own cord. Contact with a "live" wire will make
exposed metal parts of the tool "live" and
shock the operator.
Always unplug the tool from the power
source before changing accessories or
making any adjustments. Accidental start
up may occur causing serious personal
injury.
Always wear safety goggles or eye
protection, leather gloves and safety
shoes when using this tool. Shears
produce sharp metal strips or edges that if
contacted can lacerate skin easily.
Wear ear protectors when using the tool
for extended periods. Prolonged exposure
to high intensity noise can cause hearing
loss.
Use thick cushioned gloves and limit the
exposure time by taking frequent rest
periods. Vibration caused by shearing
action may be harmful to your hands and
arms.
Do not run the tool while carrying it at
your side. The cutters could become
entangled with clothing and injury may
result.
Always use the supplied hand guard. The
guard helps keep the sharp metal strips or
pieces away from contacting your hand.
BM 3609929809 10/03 10/1/03 9:05 AM Page 3
Secure the material being cut. Never hold
small pieces in your hand or across your
legs. Do not touch cutters or reach below
work or remove cut material during use of
the shear. Shears that cut metal will cut skin
easily.
Protect the cord from sharp metal edges
or strips while shearing metals. Position
the cord clear of rotating bit. Sharp metal
edges can pierce the jacket of the cord,
which can be a shock hazard.
Do not cut material greater than the rated
capacity of the shear. Cutting material
greater than the capacity of the shear may
cause damage to the cutting edges of the
shear.
Do not use dull or damaged cutters or
accessories not intended for this shear.
Replace worn cutters. Sharp cutters
minimize stalling.
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.

Operating Instructions
Assembly
ROTATING / CHANGING THE CUTTERS
Always unplug the tool from the power source
before changing accessories or making any
adjustments.
The upper and lower cutters and are identical,
each has four cutting edges and can be
interchanged or rotated.
When the cutting performance is
unsatisfactory, rotate each cutter 90° or
replace.
Loosen the screw of the respective cutter,
rotate the cutter 90° and re-tighten the screw.
Ensure that the lower cutter rests against the
adjustment screw.
ADJUSTING THE CUTTER CLEARANCE
The cutter clearance a has been
adjusted at the factory to 0.008"
and does not need to be
changed.
For working primarily with ductile, brittle or thin
sheet metal, the following values/cutter
clearance gives optimum cutting results:
Metal Metal thickness Cutter clearance a
Thin/ductile 0.012"- 0.024" 0.004"
Brittle 0.031" - 0.047" 0.010"
Brittle 0.051" - 0.063" 0.012"
Loosen screw of the lower cutter and adjust
with the adjustment screw to the required
clearance a. Check the clearance with a
gauge. Retighten the screw (Fig. 1).
The cutters must not touch
each other.
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.

CAUTION
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
shear and learning the location of its parts.
Secure or clamp small workpieces to be cut
to prevent slippage.
Inspect the blades for excessive wear, rotate
or replace if necessary.
Always direct the cord toward the rear, and
away from the shear. Keep it away from
sharp edges.
Never start the shear with the blades in
contact with the material being cut.
Do not exceed recommended capacities for
this shear. Premature blade failure will occur
when the shear is over-gaged.
To extend blade life and prevent corrosion,
occasional light lubrication of the blades is
recommended. Any light weight machine oil
can be used for this purpose.
SLIDE ON-OFF SWITCH WITH LOCK
The tool is switched “ON” by the switch
button located at the side of the motor
housing. The switch can be locked in the
“ON” position, a convenience for long
cutting operations.
TO TURN THE TOOL “ON” without locking
it, slide the switch button forward by
applying pressure ONLY at the REAR
portion of the button. When pressure is
released the switch button will snap to
“OFF” position.
TO LOCK THE SWITCH “ON”, slide the
switch button forward and press “IN” the
FRONT portion.
TO UNLOCK THE SWITCH, simply press
and release the REAR portion of the button.
Upper and Lower Cutters are the same. Reorder #2 608 635 243.
BM 3609929809 10/03 10/1/03 9:05 AM Page 7
a
Before cutting, lightly oil the cutting line.
Hold the tool at a angle 80° to 90° to the metal
surface (Fig. 2).
Excessive feed rates reduce the performance
considerably and shorten the life of the
cutters.
Sharp cutters produce good cutting results
and protects the tool.
Do not load the tool so heavily that it stalls.
Cutting curved lines: Do not tilt the tool and
work with low feed rate.

Tool Tips
Switch is spring loaded and will snap back
automatically.
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.
HAND GUARD
The hand guard protects the hands while
cutting, and deflects material downwards
and away from the operator. The hand guard
must be used at all times while using this
shear.

Service
Preventive maintenance
performed by unauthorized
personnel may result in misplacing of
internal wires and components which
could cause serious hazard. We
recommend that all tool service be
performed by a Bosch Factory Service
Center or Authorized Bosch Service Station.
TOOL LUBRICATION
Your Bosch tool has been properly
lubricated and is ready to use. It is
recommended that tools with gears be
regreased with a special gear lubricant at
every brush change.
CARBON BRUSHES
The brushes and commutator in your tool
have been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend
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 Bosch Factory
Service Center or Authorized Bosch Service
Station. Bearings which become noisy (due
to heavy load or very abrasive material cutting) should be replaced at once to avoid
overheating or motor failure.
Cleaning
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 dry 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.
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.

CAUTION
Accessories
If an extension cord is
necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your
tool must be used. This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-wire
extension cords that have 3-prong plugs and
receptacles.
NOTE: The smaller the gauge number, the heavier
the cord.
