English
(When using dust collector (B) attached to a drill bit that has more than 7-15/
32" (190 mm) of overall length, dust collector (B) cannot touch the concrete
surface but rotates. Therefore please use dust collector (B) by attaching to drill
bits which have 6-17/32" (166 mm), 6-19/64" (160 mm) and 4-21/64" (110 mm)
overall length.
⅜ Dump particles after every two or three holes when drilling.
⅜ Please replace the drill bit after removing dust collector (B).
8. Selecting the driver bit
Screw heads or bits will be damaged should an inappropriate bit for the screw
diameter be employed to drive in the screws.
9. Selecting the function mode
You can switch functions to the 3 modes of “strike only, “rotation + strike”, and
“rotation only” by turning the change lever while pressing the push button.
Set the mark position of the change lever to that of the mode to be used.
CAUTION:
⅜ Before operating the change lever, check and make sure that the motor has
stopped.
A failure can occur if it is operated while the motor is running.
⅜ If the change lever does not move up to the mark position of each mode, carry
out switching while turning the grip end to left and right. Also, it can become
difficult to change the mode at low temperature, and therefore perform
warming-up.
⅜ To operate the change lever, press the push button, and release the lock of the
change lever. Also, check and make sure after operation that the push button
has returned and that the change lever has been locked.
⅜ Switch the change lever without mistake. If it is used at a position halfway,
there is a fear that the service life of the switching mechanism may be shortened.
⅜ Note that it is impossible to switch from “rotation only” to “strike only” or
from “strike only” to “rotation only”. Switch over via “rotation + strike”.
