Soft Starting
The soft starting function limits the speed when
switching on and then automatically increases the
speed, which, for example, prevents jerky starting
when inserting the drill bit into an existing hole.
Switching the Torque
(BMH 40-XES)
Actuate the torque selector switch 8 only
when the machine is stopped and when the
application tool is free.
Low torque:
Set the torque selector switch 8 to the upper position.
High torque:
Set the torque selector switch 8 to the bottom posi-
tion.
After a power failure, the torque selector switch
automatically resets to the „Low torque" setting.
This function reduces the danger of injury, as most
applications are possible in the „Low torque" setting.
Setting the Speed/Impact Rate
The electronic control enables variably adjustable
impact rate/speed preselection for jobs suitable for
the material being worked.
The constant electronic control keeps the preselected
impact rate/speed between operation with no-load
and load almost constant.
Select the impact rate/speed preselection with dial
control 9 according to the material.
Mode Selector Switch
Operate the mode selector switch 4 only when
the machine is at a standstill.
Set the mode selector switch 4 to the required posi-
tion:

Safety Clutch
If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted.
(Disengagement torque of the clutch: 40 Nm and
80 Nm)
Because of the forces that occur, always hold the
power tool firmly with both hands and provide for
a secure stance.
If the drilling tool jams, switch the machine off and
loosen the drilling tool. When switching the machine
on with the drilling tool jammed, high reaction tor-
ques can occur!
Changing the Chiselling Position
The chisel can be locked in 18 positions. In this man-
ner, the optimum working position can be set for
each application.
Insert the chisel in the tool holder.
Turn the mode selector switch 4 to "Changing the
chiselling position".
Turn the tool holder to the desired chiselling position.
Allow the mode selector switch 4 to latch in the "Chisel-
ling" position. The tool holder is locked in this position.
Working Instruction
Vibration Damping
The integrated vibration damping feature reduces
occurring vibrations.
The soft grip handle increases the safety against slip-
ping off, and thus provides for a better grip and
handling of the power tool.
Dust Extraction
– Dusts from materials such as lead-containing
coatings, some wood types, minerals and metal
can be harmful to one's health. Touching or
breathing-in the dusts can cause allergic reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dusts, such as oak or beech dust, are con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked by specialists.
- Provide for good ventilation of the working place.
- It is recommended to wear a P2 filter-class res-
pirator.
Observe the relevant regulations in your country
for the materials to be worked.
