CAUTION:
When changing the rotational speed with the shift knob, confirm that the switch is off.
Changing the speed while the motor is rotating will damage the gears.
When a large force is required for operation (operations indicated in the following
chart) set the shift knob to "LOW". If "HIGH" is set and the unit is used, it may cause
the motor to burn out or malfunction prematurely.
In the work of the save mode (S), avoid the continuous screw-tightening as temperature
of electronic components of the converter switch increases.

9. Confirm the cap position <DV18DL> (See Fig. 21)
The three modes of screwdriver, drill and hammer drill
can be switched by the position of the cap in this unit.
(1) When using this unit as a screwdriver, line up the
one of the numbers "1, 4, 7 ... 22" on the cap, or the
black dot, with the triangle mark on the outer body.
(2) When using this unit as a drill, line up the cap drill mark
" " with the triangle mark on the outer body.
(3) When using this unit as a hammer drill, align the
cap hammer mark " " with the triangle mark on
the outer body.
CAUTION:
The cap cannot be set between the numerals "1, 4,
7 ... 22" or the black dot.
Do not use with the cap numeral at "22" and the
black line at the middle of the drill mark. Doing so
may cause damage. (See Fig. 22)
10. Rotation to Hammer changeover <DV18DL>
The "Rotation (Rotation only)" and "Hammer (Ham-
mer + Rotation)" can be switched by aligning the
drill mark " " or the hammer mark " " with the
triangle mark on the outer body.
To make holes in the metal, wood or plastic, switch
to "Rotation (Rotation only)".
To make holes in the bricks or concrete blocks,
switch to "Hammer (Hammer + Rotation)".
CAUTION:
Do not use the Cordlless hammer drill in the "Hammer" setting if the material can be
bored by rotation only. Such action will not only reduce drill efficiency, but may also
damage the drill tip.
