Smooth start:
The electronics system only increases impact
speeds slowly after switching on so that the chisel
or the drill retains the desired position on the
masonry. When the drill is inserted in an existing
hole, there are no jerks and jolts during start-up.
Electronic impact force and speed controller
Speed and impact frequency per minute can be
adjusted on the tool to match the application.
To reduce cracking when chiselling and drilling in
soft and brittle materials.
To produce an optimised tool setting for extremely
precise chiselling and drilling.
Turn-off carbon brushes
If the brushes are completely worn, the machine
switches off automatically.
Only KHE 75: An LED warns before the brushes
are completely worn.
Metabo CODE! System
Electronic anti-theft device at the push of a button.
With the CODE! key, which is available separately,
you can lock up your power tool and thus protect
it against misuse or theft.
Overload clutch
The overload clutch limits the maximum torque if
the tool should happen to block during operation.
This protects the gear unit and motor from over-
loading.
Before plugging in, check to see that the
rated mains voltage and mains
frequency, as stated on the rating label,
match with your power supply.
Use only extension cables with a min. cross-
section of 1.5 mm
2
. Extension cables must corre-
spond to the power consumption of the machine
(cf Technical Specifications). If a cable roller is
used, always roll up the cable completely.
