NOTE
○ This function helps prevent nuts from dropping when
loosening them.
○ Depending on factors such as the bolt or nut size,
socket used, and extent of tightening, there is a risk of
nuts accidentally dropping if the nut becomes detached
from the screw thread while the power tool is operating.
MAINTENANCE AND INSPECTION
WARNING
Be sure to turn off the switch and remove the battery
before maintenance and inspection.
1. Inspecting the socket
A worn or deformed hex. or a square-holed socket will
not give an adequate tightness to the fitting between the
nut or anvil, consequently resulting in loss of tightening
torque. Pay attention to wear of a socket holes
periodically, and replace with a new one if needed.
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.
TROUBLESHOOTING
Use the inspections in the table below if the tool does not operate normally. If this does not remedy the problem, consult
your dealer or the HiKOKI Authorized Service Center.

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. Storage
Store the power tool and battery 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,
significantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, significantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to five 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 modified (such as
disassembly and replacement of cells or other internal
parts).
NOTE
Due to HiKOKI's continuing program of research and
development, the specifications herein are subject to
change without prior notice.
