When a chisel is fitted, only operate the
machine in the chiselling operating mode .

7.4 Setting impact force
(KH 18 LTX BL 28 Q)
Press the button (16) to change the impact force
(and the speed) (From 100% to 70%: Not while the
motor is running).
Button (16)
illuminates : reduced impact force,
reduced speed ( approx. 70% )
Button (16) not illuminated : maximum impact
force,
high speed ( 100% )
The correct setting is found by trial and error.
Example: if work is being completed on soft, brittle
material or if you want to keep breakage to a low
level, work at “reduced impact force”.
Use the “maximum impact force” setting for working
with harder materials.
7.5 Selection of direction of rotation
Only activate the rotation selector switch (12)
when the motor has completely stopped.
Select direction of rotation:
R = clockwise rotation (for drilling, hammer
drilling, chiselling, drive in screws)
