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 cordless disc grinder 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
the
fi
lter
After use, detach the
fi
lter and remove any grime
or dust from the screen with an airgun or other tool.

NOTE
○
To clear the unit of grime or dust, periodically run
the motor in a no-load state and blow dry air into
the ventilation hole with the
fi
lter removed.
Accumulation of grime or dust accumulates in the
motor can cause damage.
○
After cleaning, make sure to securely attach the
fi
lter.
7. Storage
Store the cordless disc grinder 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.
