* 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 off the 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 fl ying
fragments.
3. Check hydraulic oil volume
Over 70% of reduced cutting power is the result of
insuffi cient 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
Figure Page
loose, retighten them immediately. Failure to do so could
result in serious hazard.

5. Maintenance of the motor
3 187
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
4 188
become damaged and/or wet with oil or water.
6. Inspecting the carbon brushes (Fig. 11)
5 188
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
6 188
brush with new ones when it becomes worn to or near
the "wear limit" ⓐ. In addition, always keep carbon
7 189
brushes clean and ensure that they slide freely whithin
8 190
the brush holders.
NOTE
9 190
When replacing the carbon brush with a new one, be
10 191
sure to use the HiKOKI Carbon Brush Code No. 999100.
7. Replacing carbon brushes (Fig. 11)
11 192
Take out the carbon brush by fi rst removing the brush
― 193
cap and then hooking the protrusion of the carbon brush
with a fl at 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 fi nger. 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.
Deformation/ Make sure the lithium-ion batteries have been fully
Chipping charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve 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 modifi ed (such as
disassembly and replacement of cells or other internal
parts).
