•Specifications may differ from country to country.
General safety rules (for all tools)
Warning: Thoroughly read and understand all instructions. Failure to follow the instructions listed below
may result in electric shock, fire and/or personal injury. Save the instructions for future reference!
Work area safety
•Keep your work area clean and well lit. Cluttered benches and dark areas lead to accidents.
•Do not operate power tools in explosive atmospheres, e.g., near flammable liquids, gases
or dust. Power tools create sparks which might ignite dust or fumes.
•Keep bystanders, children and visitors away while operating the tool. Distractions can
cause loss of control.
Electrical safety
•Power tool plugs must match the outlet. Never modify the plugs in any way. Do not use
any adapter plugs with earthed power tools. Unmodified plugs and matching outlets will
reduce the risk of electric shocks. Do not change the plug in any way. Double insulation
eliminates the need for a three-wire earthed power cord and a grounded power supply system.
•Avoid body contact with grounded surfaces such as pipes, radiators, cookers and refrig-
erators. These provide an increased risk of electric shock if your body is grounded.
•Do not expose power tools to rain or moisture. Water entering a power tool will increase the
risk of electric shocks.
•Do not abuse the cable. Never use the cable to carry a tool or pull the plug from the
socket. Keep the cable away from heat, oil, sharp edges or moving parts. Immediately replace
damaged cables. Damaged cables increase the risk of electric shock.
•When operating a power tool outside, use an outdoor extension cord. This type of cords
is rated for outdoor use and reduce the risk of electric shocks.

Personal safety
•Stay alert, concentrate on what you are doing and use common sense when operating a
power tool. Do not use the tool while tired or under the influence of drugs, alcohol or medica-
tion. A moment of inattention while operating power tools may result in serious personal injury.
•Dress properly. Do not wear loose clothing or jewellery. Tie long hair together. Keep your
hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
•Avoid accidental starting. Be sure that the switch is turned off before plugging in the
device. Carrying tools with your finger put on the switch or plugging tools in which have the
switch turned on may lead to accidents or injury.
•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
enable better control of the tool in unexpected situations.
•Use safety equipment. Always wear eye protection. Dust mask, non-slip safety shoes, a
hard hat and hearing protection must be used for appropriate conditions. Ordinary eye or
sun glasses are no eye protection.
Tool use and care
•Use clamps or other ways to secure and support the workpiece to a stable platform. Work
pieces held by hand or against your body are unstable and may lead to a loss of control.
•Do not force the tool. Use the correct tool for your application. The correct tool for the right
job will work better and safer at the rate which it was designed for.
•Do not use the tool if the switch does not work properly. 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
equipment or storing the tool. These preventive safety measures reduce the risk of starting
the tool accidentally.
•Store idle tools out of reach of children and other untrained people. 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.
•Check for misalignment or smoothly operating moving parts, broken parts and any other
condition that may affect the operation. If the tool is damaged, have it serviced before re-
using it. Many accidents are caused by poorly maintained tools.
•Only use equipment that is recommended by the manufacturer for your model. Equipment
that may be suitable for one tool might be dangerous 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 injury.
•When servicing a tool, use only identical and original replacement parts. Follow the instructions
in the “maintenance” section of the manual. Use of unauthorised parts or failure to follow mainte-
nance instructions may create a risk of electric shock or injury.

Specific safety rules
•Do not let comfort or familiarity with the product (gained from repeated use) replace strict ad-
herence to the nibbler safety rules. If you use this tool unsafely or incorrectly, you can suffer
serious personal injury.
•Always be sure that the tool is switched off and unplugged before carrying out any work
on the tool.
•Always lead the power supply cord away from the tool towards the rear.
•Do not touch the blade or the workpiece immediately after operation; it might be ex-
tremely hot and could burn your skin.
•Hold the tool by the insulated gripping surfaces when performing an operation where the
cutting tool may get in contact with a hidden wiring or its own cable. Contact with an
electrified wire will make exposed metal parts of the tool conduct the electricity and shock the
operator.
•Hold the tool firmly with both hands.
•Apply the machine to the workpiece only when switched on.
•Always switch the machine off and wait until it has come to a standstill before placing it
down.
•Never allow children to use the machine.
•Some material contains chemicals which might be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material supplier safety data.
Warning: Save these instructions warning: misuse or failure to follow the safety rules stated in
this instruction manual may cause serious personal injury.

Functional description
Assembly
•Installing and removing the punch and die:
Caution: Always be sure that the tool is switched
off and unplugged before removing or installing
the punch and die.
•Make sure to replace the punching needle and
the punching die set. When disassembling them,
loosen the cap nut with the wrench and disas-
semble the rod out of the tool. Then loosen the
nut fastening the punching die with a hex wrench.
Disassemble the punching die out of the rod and
then loosen the screw rod fastening the punching
needle with a hex wrench. Pull the punching nee-
dle out of the rod (Fig. 1 and 2).
•When assembling the punching needle and the

Line of cut (Fig. 7)
The gap on the blanking rod indicates the line of the cut. The width of the
gap is the same as the width of the cut. Make sure to align the cutting line on the work piece with the
gap.
•Pre-grease: Coat the cutting line of the workpiece with oil to in-
crease the efficiency and strengthen the durability. It’s especially
important when cutting aluminium.
•Method of die cut (Fig. 8): Hold the electric tool to make the die
cut chip at right angles (90°) to the workpiece being cut and push
the machine slightly according to the cut direction.
•Cut-outs (Fig. 9): Cut-outs can be done by first opening a round
hole of at least 21 mm in diameter which the cutting head can be
inserted into.
Cutting corrugated or trapezoidal metal sheets
When cutting corrugated or trapezoidal metal sheets, make the punch
face the cut direction whether to cut it at an angle or at right angles. When
operating the direction of holding the tool must run parallel to the corru-
gating direction. Make sure that the die cutting chip works at right angles
(90°) to the workpiece being cut (Fig. 10 and 11).
Maintenance and daily care
Caution: Always be sure that the tool is switched off and unplugged be-
fore attempting to perform inspection or maintenance.
•The tool and its air vents have to be kept clean. Regularly clean
the tool’s air vents or when the vents start to become dirty.
•Check all the screws periodically if they are loose and tighten
them if so.
•Check the cable insulation regularly.
Replacing carbon brushes
•Remove and check the carbon brushes regularly. Replace when
the tool produces obvious sparks or the brushes are strongly worn
down.
•Both carbon brushes should be replaced at the same time. Only
use the original brushes provided.
•Use a screwdriver to remove the brush holder caps. Take out the
worn carbon brushes, insert the new ones and secure the brush
holder caps.
Caution: Be sure to re-install the knob after inserting new carbon brush.
•After replacing brushes, plug in the tool and break in brushes by running the tool without for
about 10 min. Then check the tool while running, when releasing the switch trigger. If the tool is
not working well, ask your authorised service centre for repair.
•To maintain product safety and reliability, repairs or any other maintenance should be performed
by and an authorised service partner, always using original replacement parts.
