MAINTENANCE AND INSPECTION

(mm)
CAUTION
Be sure to turned off the switch and remove the battery
2.5 – 6
before maintenance and inspection.
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
2.5 – 6
reduced cutting effi ciency and may cause overloading of
the motor. Replace the blade with a new one as soon as
excessive abrasion is noted.
2. Inspecting the mounting screws
2.5 – 6
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
2.5 – 6
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
Below 3.5
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
Below 3.5
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
2.5 – 6
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
2.5 – 6
charged before storing them.
Prolonged storage (3 months or more) of batteries with
100
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
100
the batteries incapable of holding a charge.
100
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.
