When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use reduces the risk
of electric shock.
If operating a power tool in a damp location is
unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD
reduces the risk of electric shock.

Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
serious injury.
medication.
A
moment of inattention while
operating power tools may result in serious
personal injury.
12. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, nonꢀskid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
13. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools
with your finger on the switch or energising power
tools that have the switch on invites accidents.
14. Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool
may result in personal injury.
Save all warnings and
instructions for future reference.
The term "power tool" in the warnings refers to your
mainsꢀoperated (corded) power tool or batteryꢀoperated
(cordless) power tool.
Work area safety
1.
Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2.
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.

15. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
16. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving
parts.
17. If devices are provided for the connection of
dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dustꢀ
related hazards.
26. Follow instruction for lubricating and
changing accessories.
27. Keep handles dry, clean and free from oil and
grease.

4.
Hold the tool firmly.
Secure the workpiece firmly.
Keep hands away from moving parts.
Edges and chips of the workpiece are sharp.
Wear gloves. It is also recommended that you
put on thickly bottomed shoes to prevent
injury.
Power tool use and care
5.
Do not put the tool on the chips of the
workpiece. Otherwise it can cause damage
and trouble on the tool.
18. Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
19. Do not use the power tool if the switch does
not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous
and must be repaired.
6.
7.
Do not leave the tool running. Operate the tool
only when hand-held.
Always be sure you have a firm footing.
Be sure no one is below when using the tool
in high locations.
8.
9.
Do not touch the punch, die or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
Avoid cutting electrical wires. It can cause
serious accident by electric shock.
20. Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
21. Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
22. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many
accidents are caused by poorly maintained power
tools.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this
instruction manual may cause serious personal
injury.
23. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
24. Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
25. Have your power tool serviced by a qualified
repair
person
using
only
identical
replacement parts. This will ensure that the
safety of the power tool is maintained.

The thickness of material to be cut depends upon the
tensile strength of the material itself. The groove on the
die holder acts as a thickness gauge for allowable
cutting thickness. Do not attempt to cut any material
which will not fit into this groove.
Fit the wrench provided onto the lock nut and tap the
handle lightly with a hammer to loosen the lock nut.
Take off the die holder and use a wrench to remove the
screw. Then remove the punch.

To install the punch, insert it into the punch holder with
its cutting edge facing forward so that the pin in the
punch holder fits into the groove in the punch. Install the
screw and lock nut. Then tighten them securely.
NOTE:
•
When installing the screw and lock nut, be sure to
tighten securely. If they become loose during
operation, the tool may break down.

Before plugging in the tool, always check to see
that the switch trigger actuates properly and
returns to the "OFF" position when released.
Switch can be locked in "ON" position for ease of
operator comfort during extended use. Apply
caution when locking tool in "ON" position and
maintain firm grasp on tool.

To stop the tool from the locked position, pull the switch
trigger fully, then release it.

There is more vibration when cutting stainless steel than
mild steel. Less vibration and better cutting is possible
by adding another washer (standard equipment)
beneath the die.
OPERATION
CAUTION:
Use the hex wrench provided to remove the two screws
and insert the washer below the die. Replace screws
and tighten securely.
•
Hold the tool firmly with one hand on the main
handle when performing the tool.
Pre-lubrication
Coat the cutting line with machine oil to increase the
punch and die service life. This is particularly important
when cutting aluminum.
MAINTENANCE
CAUTION:
Cutting method
•
•
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may
result.
The tool and its air vents have to be kept clean.
Regularly clean the tool's air vents or whenever the
vents start to become obstructed.
Punch & die service life
013359
Replace or sharpen punch and die after cutting the
lengths indicated in the accompanying table. Their life,
of course, depends upon the thickness of materials cut
and lubrication conditions.
Smooth cutting is achieved by holding the tool upright
and applying gentle pressure in the cutting direction.
Apply tool oil to the punch about every 10 meters of mild
steel or stainless steel to be cut. Light oil or kerosene
should be used to keep an aluminum lubricated
continuously. Failure to lubricate aluminum in the cut will
cause chips to adhere to the tool, dulling the die and
punch and increasing load on the motor.

Die
Replace after 150 m of 3.2 mm steel sheet
Sharpen after 300 m of 3.2 mm steel sheet

When cutting is poor even after replacing the punch,
sharpen the die. Grind down the dull edge shown in the
figure using a grinder. After roughꢀgrinding the dull
portion, finish with a dressing stone. Stock removal
should be about 0.3 to 0.4 mm.

Cutting stainless steel
When installing ground die, a clearance of 3.5 to 4.0
mm should be obtained by attaching one or two of the
washer provided, as shown in the figure. Failure to have
the proper clearance will result in vibration during
cutting.
