6 Special Product Features
Exchangeable chuck
(not KHE 22 SP, KHE 24 SP, KHE 26 SP, BHE 22,
BHE 20 SP):
With a simple operation and without the need for
extra tools the SDS chuck is exchanged against the
keyless chuck.
Single-knob control
With only a single control knob the operating mode
(drilling, hammer drilling, chiselling, depending on
the model) is selected.
Rotary stop:
(KHE 28, KHE 26 Contact, KHE 26, KHE 26 SP,
KHE 22 SP, KHE 24 SP, KHE Partner Edition):
By turning the rotation off chiselling can be done.
Metabo S-automatic safety clutch:
If the insertion tool jams or hooks, the power flow to
the engine will be restricted. Because of the high
power which then arises, always hold the machine
with both hands on the handles, stand safely, and
concentrate on your work.
Auto-stop carbon brushes
If the brushes are completely worn, the machine
switches off automatically.
With VTC electronics: A LED warns before the
brushes are completely worn.
Restart protection on machines with
VTC electronics
(KHE 28, KHE 26, BHE 26, KHE 26 SP,
KHE Partner Edition)
The restart protection prevents unintentional
starting when being plugged in again or when
power is restored after a power failure.
