7. Rotation to Hammer changeover (DV18DEX)
The "Rotation (Rotation only)" and "Hammer (Hammer
+ 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 Cordless hammer drill in the
"Hammer" setting if the material can be bored
by rotation only. Such action will not only reduce
drill effi ciency, but may also damage the drill tip.

8. Tightening torque adjustment.
(1) Tightening torque
Tightening torque should correspond in its intensity to
the screw diameter. When too strong power is used,
the screw head may be broken or be injured.
Be sure to adjust the clutch dial position according to
the screw diameter.
Refer to Table 6 for the clutch dial position tightening
torques.
(2) Tightening torque indication (See Figs. 12 and 14)
The tightening torque diff ers depending on the type of
screw and the material being tightened.
The unit indicates the tightening torque with the
numbers "1, 4, 7 ... 22" on the clutch dial, and a dot.
The tightening torque at position "1" is the weakest
and the torque is strongest at the highest number.
(3) Adjusting the tightening torque (See Figs. 12 and 14)
Rotate the clutch dial and line up the numbers "1, 4,
7, ... 22" on the clutch dial, or the dot, with the triangle
mark on the outer body. Adjust the clutch dial in the
weak or the strong torque direction according to the
torque you need.

9. Switch operation
○ When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
When releasing the trigger of the switch, the brake will
be applied for immediate stopping.
○ 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.
