Maintenance And Inspection - Hitachi DS 9DVA Bedienungsanleitung

English
CAUTION
The selection examples shown in Table 5 should
be considered as a general standard. As different
types of tightening screws and different materials
to be tightened are used in actual works proper
adjustments are usually necessary.
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 tightening a machine screw.
NOTE
The use of the battery EB9H 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 efficiency and
cause possible motor malfunction, sharpen or re-
place 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. Fail-
ure 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 thin-
ner, as 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
Due to HITACHI's continuing program of research and
development, the specifications herein are subject to
change without prior notice.
