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
(BHE 24, KHE 24, KHE 28 )
The restart protection prevents unintentional
starting when being plugged in again or when
power is restored after a power failure.
Metabo contact mode:
(KHE 24 Contact)
For intelligent drilling in walls with installed electric
or water lines. As soon as the inserted tool makes
contact with conductive, earthed material or live
supply cables, the machine switches off
immediately.
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.
8.1 Side handle installation
For safety reasons, always use the side
handle supplied.
Open the clamping ring by turning the side handle
(17) counter-clockwise. Slide the side handle onto
the spindle collar of the machine. Insert the depth
stop (7). Tighten the side handle at an angle as
required for the application.
9.1 Depth Stop Setting
Loosen the side handle (17). Set depth stop (7) to
the desired drilling depth and retighten the side
handle.
9.2 Switching on/off
To start the machine, press the trigger (14).

With only a single control knob the operating mode
Metabo S-automatic safety clutch.
When the safety clutch responds, switch off the
machine immediately!
Avoid unintentional starting: always unlock the
trigger switch if the machine is unplugged or in the
event of a power failure. Not required for drills with
VTC electronics (restart protection).
For safety reasons, always use the side handle
supplied.
Do not grasp the rotating tool!
Remove chips and similar matter only with the
machine at standstill.
Hold the power tool only at insulated housing
parts, if there is a possible hazard of making
contact with concealed electric cables or the
supply cable.
Contact with live wires energizes
the metal parts of the housing and can cause
electric shock to the operator.
Wear hearing protection when working for a
longer period of time.
High noise levels over a
prolonged period of time may affect your hearing.

9.6 Tool Change with SDS Chuck
Before fitting, clean tool shank and apply
special grease! Use only SDS-Plus tools!
Inserting the tool:
Turn the tool while inserting, until it engages. The
tool is automatically locked.
Removing the tool:
Turn tool lock (3) in direction indicated by arrow (a)
and remove the tool (b).
9.7 Tool change with Futuro Plus keyless
chuck (not BH 20, BHE 20)
Insert tool. Grip the retaining ring (a) firmly and,
with the other hand, turn sleeve (b) towards "GRIP,
ZU", until the mechanical resistance which can be
felt is overcome.
Caution! The chuck is not yet fully tightened! Keep
turning (there is a "clicking" sound while turning),
until further turning is no longer possible - only now
is the tool securely tightened.
With a soft tool shank, retightening may be
required after a short period of operation.
Opening the drill chuck:
Grip the retaining ring (a) firmly and, with the other
hand, turn the sleeve (b) towards "AUF,
RELEASE".
Note: The ratchet sound which can possibly be
heard after opening the drill chuck, is functional
and is switched off by a reverse rotation of the
sleeve.
If the chuck is extremely tightened:
Unplug. Hold drill chuck with an open end spanner
at the flats on its head and turn the sleeve (b) hard
towards "AUF, RELEASE".
9.8 Contact mode (KHE 24 Contact)
To enable the contact mode, press button (11).
If required, e.g. for drilling into steel girders or
steel-reinforced concrete walls, the contact mode
can be disabled by pressing the button (11).
The contact mode indicator (10) shows the current
setting:
Green: contact mode enabled.
Red: machine has switched off because
contact was made with conductive, earthed
material or a live supply cable.
Pull machine back and bit out of the hole
immediately. Have possible damage
properly repaired.
Off: contact mode disabled.
Only moderate pressure is required for hammer
drilling and chiselling. Exerting a high force does
not increase performance.
When drilling deep holes, remove the drill bit
periodically from the hole to release the stone
dust.
Drill tiles and other brittle materials without impact.
Keyless chuck cleaning:
After prolonged use hold the chuck vertically, with
the opening down, and fully open and close it
several times. The dust collected falls from the
opening. The application of cleaning spray to the
jaws and jaw openings at regular intervals is
recommended.
The vent slots of the machine should be cleaned
from time to time.
