MAINTENANCE AND INSPECTION

1. Inspecting the driver bit

Using a broken bit or one with a worn out tip is dangerous

because the bit can slip. Replace it.

2. 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.

3. 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.

4. 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.

5. Storage

Store the power tool in a place in which the temperature

is less than 40°C and out of 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 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).

GUARANTEE

We guarantee HiKOKI Power Tools in accordance with statutory/

country speciﬁ c regulation. This guarantee does not cover defects

or damage due to misuse, abuse, or normal wear and tear. In case

of complaint, please send the Power Tool, undismantled, with the

GUARANTEE CERTIFICATE found at the end of this Handling

instruction, to a HiKOKI Authorized Service Center.

Information concerning airborne noise and vibration

The measured values were determined according to

EN62841 and declared in accordance with ISO 4871.

Measured A-weighted sound power level: 100 dB (A)

Measured A-weighted sound pressure level: 89 dB (A)

Uncertainty K: 3 dB (A).

Wear hearing protection.

Vibration total values (triax vector sum) determined

according to EN62841.

Impact tightening of fasteners of the maximum capacity of

the tool:

Vibration emission value

Uncertainty K = 1.5 m/s

The declared vibration total value has been measured in

accordance with a standard test method and may be used

for comparing one tool with another.

It may also be used in a preliminary assessment of exposure.

WARNING

○ The vibration emission during actual use of the power

tool can diﬀ er from the declared total value depending in

the ways in which the tool is used.

○ Identify safety measures to protect the operator that are

based on an estimation of exposure in the actual conditions

of use (taking account of all parts of the operating cycle

such as the times when the tool is switched oﬀ and when it

is running idle in addition to the trigger time).

NOTE

Due to HiKOKI's continuing program of research and

development, the speciﬁ cations herein are subject to

change without prior notice.
