FEATURES OF THE CORDLESS OIL
PULSE DRIVER
The oil pulse driver uses a viscous oil to generate pressure
that rotates the driver bit. This mechanism reduces the
noises associated with tightening screws to levels that are
considerably lower than those of noises generated by other
types of impact drivers.
NOTE
The viscosity of the oil changes depending on temperature.
Note the following when using the tool:
○ Do not use the tool in an environment below -5°C, or
when it has been left to stand for a prolonged period of
time in an environment below -5°C.
Otherwise, impacts (torque) may not be generated
although the switch is pulled, or the number of impacts
that are generated may reduce signifi cantly, which may
overload the tool, and as a result, the motor may fail.
○ If the tool is very hot after it has been continuously
used for a certain period of time, continuing the work
may make it diffi cult to tighten screws as the tool in
this condition may not be able to generate a suffi cient
amount of torque. In this case, turn off the switch and do
not use the tool for 30 minutes or more.
○ This product utilizes a hydraulic impacting mechanism.
This means that the protective function incorporated in
the lithium ion battery may not work when the viscosity
of the oil is within a certain range, which may cause the
motor to fail.
Do not use the product in a cold environment (-5°C or
less) or continuously under conditions in which the
product may be overloaded.
MAINTENANCE AND INSPECTION
1. Inspecting the driver bit
Using a broken driver bit or one with a worn out tip is
dangerous because the driver 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: 90 dB (A)
Measured A-weighted sound pressure level: 79 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.
