General power tool safety
warnings
WARNING: Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious injury.
Save all warnings and
instructions for future reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(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.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
Electrical safety
1. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
..... Read instruction manual.
........ Only for EU countries
Due to the presence of hazardous
components in the equipment, waste
electrical and electronic equipment,
accumulators and batteries may have a
negative impact on the environment and
human health.
Do not dispose of electrical and
electronic appliances or batteries with
household waste!
In accordance with the European
Directive on waste electrical and
electronic equipment and on
accumulators and batteries and waste
accumulators and batteries, as well as
their adaptation to national law, waste
electrical equipment, batteries and
accumulators should be stored
separately and delivered to a separate

2. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electric shock.
4. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock.
5. 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.
6. 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.
7. Power tools can produce electromagnetic fields
(EMF) that are not harmful to the user. However,
users of pacemakers and other similar medical
devices should contact the maker of their device and/
or doctor for advice before operating this power tool.
Personal safety
1. Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a dust
mask, non-skid safety shoes, hard hat or hearing
protection used for appropriate conditions will reduce
personal injuries.
3. 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.
4. 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.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair
can be caught in moving parts.
7. 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 dust-related hazards.
8. Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
9. Always wear protective goggles to protect your
eyes from injury when using power tools. The
goggles must comply with ANSI Z87.1 in the USA,
EN 166 in Europe, or AS/NZS 1336 in Australia/
New Zealand. In Australia/New Zealand, it is
legally required to wear a face shield to protect
your face, too.
It is an employer's responsibility to enforce the
use of appropriate safety protective equipments
by the tool operators and by other persons in the
immediate working area.
Power tool use and care
1. 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.
2. 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.
3. Disconnect the plug from the power source and/or
remove the battery pack, if detachable, 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.
4. 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.
5. Maintain power tools and accessories. 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.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
7. 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.

is safe for operation. Put on safety glasses and wear
protective clothing.
• Refer to the tool specifications in this manual and do
not cut rebar of size or hardness that exceeds the
cutting capacity of the tool.
• Do not cut material other than rebar. Please ask the
manufacturer if you want to cut other materials.
WARNING:
• Replace damaged (chipped, broken, cracked) or
deformed blades immediately. The blade will not cut
true and may fracture or break causing serious
personal injury.
Cutting Procedure
WARNING:
•Never use the tool without the protector in place.
Failure to do so can cause serious personal injury.
(Fig. 4)
• Protector is an equipment to prevent fragments from
being projected towards the operator. It does not
prevent a projection to the axial direction of the rebar.
Position yourself so that the protector blocks the
fragments.
• In some figures the protector is not shown, but it is for
showing the inside of the protector. Always use the
protector in place.
1. Position the rebar to be cut between the blades.
(Fig. 5)
Adjust the Stopper according to the diameter of the
rebar to be cut so that the rebar is at 90 degrees to the
blades. The Stopper supports the rebar and keeps it
perpendicular to the blades when cutting. (Fig. 6)
WARNING:
• When cutting rebar, adjust the Stopper according to the
diameter of the rebar to be cut so that the rebar is at 90
degrees to the blades. Without this adjustment, the cut
piece may fly off and cause serious injury to the
operator or bystanders. Never fail to check the position
of the operator relative to the tool and confirm the
safety of the operator and surrounding area.
2. Position the rebar deep enough between the blades
so that it does not touch the protector. (Fig. 7)
WARNING:
• If the rebar to be cut is not positioned fully between the
blades, the blades will be damaged; the rebar will be
ejected violently and may cause serious personal
injury.
WARNING:
• Do not cut rebar when the piece to be cut off is less
than 200 mm in length. Cutting shorter length may
cause the rebar to fly off during cut and may result in
serious personal injury. (Fig. 8)
WARNING:
• Do not cut rebar when it is not properly supported by
the Stopper. When cutting, hold the rebar on the
Stopper side. (Fig. 9, 10) If not, the cut piece may fly off
and cause serious injury to the operator or bystanders.
3. Push in the Switch Lock on Side A. The switch is
unlocked and the trigger can be operated.
4. Press the switch trigger to start cutting operation. The
Cutter Rod will move forward to cut the rebar. Keep
the Switch depressed until the Cutter Rod stops at the
end of its stroke.

5. Release the switch trigger when the cut is completed
and the Cutter Rod has reached the end of its stroke.
The Cutter Rod will then return automatically to its
starting position. The Cutter Rod will not return if the
stroke is not completed. Similarly the Cutter Rod will
not be able to move forward again until after it returns
completely to its starting position. Press the switch to
start the next cut, only after the Cutter Rod completely
returns to its starting position and stops.
WARNING:
• When cutting rebar of a high tensile strength the cut
piece may fly off and cause serious injury to the
operator. Wear safety glasses and confirm that the
surrounding area is safe before starting operation.
WARNING:
• Keep your hands and face away from the blades, the
moving parts and the cutting area, during operation.
Remove the Battery from the tool immediately after
use.
NOTE:
• If the temperature of the tool housing exceeds 70°C
(160°F), the tool capacity decreases. In such a case,
stop the use and allow the tool to cool down.
NOTE:
• Keep the air hole in the end of the Bar Holder clear of
dirt and debris. The air hole controls the internal
pressure and should not be obstructed. (Fig. 11)
Rotating Function of Motor (Fig. 12)
The Motor Body can be rotated through 360 degrees, in
either direction, during operation. This feature is
particularly useful when working in awkward or narrow
areas as it allows the operator to position the tool in the
best position for easy operation.
Return Valve Operation (Fig. 13)
The function of the Return Valve is to allow the Cutter Rod
to return to the starting position if it is unable complete a
cut or becomes jammed. Loosening the return valve half
turn will release the oil pressure and allow the Cutter Rod
to return. Retighten the Return Valve once the Cutter Rod
is fully returned and before starting the next operation.
BLADES REPLACEMENT
PROCEDURE
If the cutting edges of the blades are chipped, cracked,
deformed, or damaged in any way, their cutting ability will
be reduced. Cutting under such conditions may cause
further damage and result in personal injury. The blades
should be replaced as a set immediately if any damage is
found.
WARNING:
• When replacing the blades, ensure that the Battery is
removed from the tool to prevent accidental operation.
Ensure that Blade A, on the Bar Holder and Blade B, on
the Cutter Rod are fitted in their correct respective
positions. (Fig. 14)
1. Undo the bolts and the washers that hold Blade A and
Blade B.
2. Remove dirt and clean the surfaces where the new
blades are to be fitted.
3. Fit Blade A to the Bar Holder and Blade B to the Cutter
Rod. Replace bolts and washers and tighten firmly.
WARNING:
• The bolts that hold Blade A and Blade B should be
tightened regularly. If the bolts become loose the
Blades may be damaged and may cause personal
injury.
