MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of a dull tool will degrade effi 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. Cleaning of the outside
When the driver drill 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 driver drill 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 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).
