CAUTION:
The selection exam ples show n in Table 3 should be
considered as general standard. As different types of
tightening screw s and different m aterials to be
tightened are used in actual works proper adjustments
are naturally necessary.
When using the driver drill w ith a m achine screw at
HIGH (high speed), a screw m ay dam age or a bit m ay
loose due to the tightning torque is too strong. Use
the driver drill at LOW (low speed) w hen using a
m achine screw .
NOTE:
The use of the battery EBM 315 in a cold condition
(below 0 degree Centigrade) can som etim es result in
the w eakened tightening torque and reduced am ount
of w ork. This, how ever, is a tem porary phenom enon,
and returns to norm al w hen the battery w arm s up.
