* 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 o 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

insu 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

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 Hitachi Carbon Brush Code No. 999100.

7. Replacing carbon brushes (Fig. 11)

Take out the carbon brush by ﬁ rst removing the brush

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.

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,

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 Hitachi

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).
