NOTE:
If the sleeve is tightened in a state where the clip
of the keyless chuck is opened to a maximum limit,
a click noise may occur. This is the noise that occurs
when the loosening of the keyless chuck is prevented
and is not a malfunction.
CAUTION:
When it is no longer possible to loosen the sleeve,
use a vise or similar instrument to secure the bit.
Set the clutch mode between 1 and 11 and then
turn the sleeve to the loose side (left side) while
operating the clutch. It should be easy now to
loosen the sleeve.
7. Automatic spindle-lock mechanism
This unit has automatic spindle-lock mechanism for
quick bit changes.
8. Confirm that the battery is mounted correctly.
9. Check the rotational direction
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn
the bit counterclockwise (See Fig. 11) (The
R
marks are provided on the body).
10. Switch operation
When the trigger switch is depressed, the tool
rotates. When the trigger is released, the tool stops.
The rotational speed of the drill can be controlled
by varying the amount that the trigger switch is
pulled. Speed is low when the trigger switch is
pulled slightly and increases as the trigger switch
is pulled more.
NOTE:
A buzzing noise is produced when the motor is
about to rotate; This is only a noise, not a machine
failure.
