Maintenance And Inspection - Hitachi DB 3DL2 Handling Instructions Manual

When using the driver drill with a machine screw at HIGH (high speed), a screw
○
may damage or a bit may loose due to the tightning torque is too strong. Use the
driver drill at LOW (low speed) when using a machine screw.
NOTE
The use of the battery EBM315 in a cold condition (below 0 degree Centigrade) can
sometimes result in the weakened tightening torque and reduced amount of work. This,
however, is a temporary phenomenon, and returns to normal when the battery warms up.

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. 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 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.
5. Storage
Store the driver drill in a place in which the temperature is less than 40°C and out of reach
of children.
