Use the additional handles supplied with the
tool. Loss of control can lead to injuries.
Work only with the additional handle correctly
installed.
Always hold the machine with both hands at the
intended handles, take a secure stance and
concentrate on the work.
Always wear protective goggles, gloves, a dust
mask and sturdy shoes when working with this tool.
Wear ear muffs. Exposure to noise can cause loss
of hearing.
Ensure that the spot where you wish to work is free
of power cables, gas lines or water pipes (e.g.
using a metal detector).
Hold the power tool only at insulated housing
parts if there is any danger of making contact
with concealed electric cables or the supply
cable. Contact with live wires energises the metal
parts of the housing and can cause electric shock
to the operator.
Work only with a correctly positioned tool. Pull on
the tool to check that it is correctly seated. (The
tool must move a few centimetres in axial direc-
tion.)
When working above ground level, ensure that the
area below you is clear.
Never touch the tool or parts near the tool directly
after work because they may be extremely hot and
can cause burns to the skin,
Always route the connecting cable away from the
tool towards the rear.

5 Special Product Features

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.

6 Assembly, Initial Use

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 AWG 16. 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.
