MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of as 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. Cleaning on 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.
4. Storage
Store the driver drill in a place in which the temperature
is
less than 40°C and out of reach of children.
NOTE
Make sure that the battery is fully charged when stored
for a long period (3 months or more). The battery with
smaller capacity may not be able to be charged when
used, if stored for a long period.
