LUBRICATION
Low viscosity grease is applied to this rotary hammer so
that it can be used for a long period without replacing the
grease. Please contact the nearest service center for grease
replacement when any grease is leaking form loosened
screw.
Further use of the rotary hammer despite the grease
shortage causes damage to reduce the service life.
CAUTION
A
speci
fi
c grease is used with this machine, therefore,
the normal performance of the machine may be badly
a
ff
ected by use of di
ff
erent grease. Please be sure to let
one of our service centers to undertake replacement of
the grease.
MAINTENANCE AND INSPECTION
CAUTION
Be sure to turned o
ff
the switch and remove the battery
before maintenance and inspection.
1. Inspecting the tool
Since use of as dull tool will degrade e
ffi
ciency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
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. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
5. 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.
6. Cleaning of the battery installation compartment
After drilling concrete, if concrete dust has accumulated
on the terminals or the area where the battery slides
within the battery installation compartment, clean o
ff
the
accumulated concrete dust with a dry cloth before using
the tool. (
Fig. 14
)
Also, after cleaning, ensure that the battery can be
installed and removed smoothly from the tool.
CAUTION
Using the tool when the battery is covered with concrete
dust may lead to accidents such as the battery falling
during use.
Furthermore, such use may cause a malfunction or
contact failure between the battery and the terminals.
7. 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,
signi
fi
cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However,
signi
fi
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 modi
fi
ed (such as
disassembly and replacement of cells or other internal
parts).
NOTE
Due to HiKOKI’s continuing program of research and
development, the speci
fi
cations herein are subject to
change without prior notice.
