CAUTION
● The clutch dial cannot be set between the
number "1, 4, 7 ... 22" or the dot.
● Do not use with the clutch dial number at "22"
and the line at the middle of the drill mark. Doing
so may cause damage. (See Fig. 14)

7. Rotation to Hammer changeover (DV18DBFL2)
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.
(2) Tightening torque indication (See Fig. 11, 13)
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 Fig. 11, 13)
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.
10. For drilling into brick (DV18DBFL2)
Excessive pressing force never increases drilling
speed. It will not only damage the drill tip or reduce
working effi ciency, but could also shorten the service
life of drill bit. Operate the hammer drill within 10-20 kg
pressing force while drilling into brick.
CAUTION
● The motor rotation may be locked to cease while
the unit is used as drill. While operating the
driver drill, take care not to lock the motor.
● If the motor is locked, immediately turn the
power off . If the motor is locked for a while, the
motor or battery may be burnt.
● Too long hammering may cause the screw
broken due to excessive tightening.
11. How to select tightening torque and rotational speed
CAUTION
● The selection examples shown in Table 6 should
be considered as general standard. As diff erent
types of tightening screws and diff erent materials
to be tightened are used in actual works proper
adjustments are naturally necessary.
