designated battery packs.
Use of any other battery packs may create a risk of
injury and fire.
GENERAL POWER TOOL SAFETY
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.
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.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) 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.

Keep cord away from heat, oil, sharp edges or
moving parts.
Damaged or entangled cords increase the risk of
electric shock.
e) 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.
f) 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.
3) Personal safety
a) 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.
b) Use personal protective equipment. Always

(Fig.3)
REGARDING ENVIRONMENT AND
CONDITIONS OF USE
This tool operates on oil pressure.
When used during the winter season or in cold conditions
the hydraulic oil’s viscosity will excessively rise to dull the
tool’s operation.
In such cases, run the tool through a warm-up operation
prior to use.
How to run a warm-up operation
Without setting up a rebar, switch on the tool and let it
continuously run for 30 to 60 seconds.
WARNING
Do not place your hands in the vicinity of the piston
during warm-up operation.
Depending on the environment and conditions of use, the
hydraulics may heat up (over 50°C). This can lower the
viscosity of the hydraulic oil and reduce its cutting power.
If this occurs, allow the tool to cool down and then resume
operation.

*Changing the cutter block
With repeated rebar cutting, the cutter block will sustain
damage such as blade wear, deformation or chipping.
When a worn, deformed or chipped cutter block is
used, the piston may not return due to the rebar not
being fully cut and remaining sandwiched by the cutter
block. Furthermore, this could lead to tool malfunction or
damage to the cutter block.
●1000 cuts per single blade location
The life (number of cuts) of a single location on the
blade is approximately 1000.
●4 blade locations on a single cutter block
There are 4 blade locations on the cutter block which
can be used by re-attaching and changing the facing
of the block 4 times.
●Change the cutter block as early as possible
Change the facing of the cutter block or exchange it if
the blade is chipped or deformed.

MAINTENANCE AND INSPECTION
1. Maintenance after use
After using the tool, put on a pair of leather gloves and
clean offthe metal particles and other waste matter
around the piston.
NOTE
Metal particle buildup can cause the piston to seize up.
WARNING
Do not blow away the waste matter with an airgun or
similar tool.
Sharp-edged fragments can cause injury when scattered
in the air.
2. Check the cutter block
Periodically check the blade for chipping or deformation.
WARNING
Replace the blade at an early stage. Using a chipped
or deformed blade could result in injury from flying
fragments.
3. Check hydraulic oil volume
Over 70% of reduced cutting power is the result of
insufficient hydraulic oil volume. Before using the tool,
always check the hydraulic oil volume.
4. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
5. Maintenance of the motor
The motor unit winding is the very “heart” of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
6. Inspecting the carbon brushes (Fig. 11)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush with new ones when it becomes worn to or near
the “wear limit” ⓐ. In addition, always keep carbon
brushes clean and ensure that they slide freely whithin
the brush holders.
NOTE
When replacing the carbon brush with a new one, be
sure to use the HiKOKI Carbon Brush Code No. 999100.
7. Replacing carbon brushes (Fig. 11)
Take out the carbon brush by first removing the brush
cap and then hooking the protrusion of the carbon brush
with a flat head screw driver, etc.
When installing the carbon brush, choose the direction
so that the nail ⓑof the carbon brush agrees with the
contact portion ⓒoutside the brush tube. Then push it in
with a finger. Lastly, install the brush cap.
CAUTION
Be absolutely sure to insert the nail of the carbon brush
into the contact portion outside the brush tube. (You can
insert whichever one of the two nails provided).
Caution must be exercised since any error in this
operation can result in the deformed nail of the carbon
brush and may cause motor trouble at an early stage.
8. Cleaning on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
9. Storage
Storing in a place below 40°C and out of the reach of
children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
significantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, significantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to five times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
Important notice on the batteries for the HiKOKI
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modified (such as
disassembly and replacement of cells or other internal
parts).
