14 Button for reduced impact force (for working in
soft material)
* model-dependent, equipment-dependent
5. Initial Operation
Before commissioning, check that the rated
mains voltage and mains frequency stated on
the type plate match your power supply.
Always install an RCD/GFCI with a maximum
trip current of 30 mA upstream.
Use only extension cables with a minimum cross-
2
section of 1.5 mm
. Extension cables must
correspond to the power consumption of the
machine (cf Technical Specifications). If a cable
roller is used, always roll up the cable completely.
5.1
Assembly of the bow handle or
additional handle
For safety reasons, always use the bow
handle (2) or additional handle (3) supplied.
MHEV...:
Release the clamping ring by turning the clamping
knob (1) anticlockwise. Adjust the bow handle (2) to
the required position and angle. Tighten the
clamping knob firmly.
KHEV...:
Open the clamping ring by turning the additional
handle (3) anticlockwise. Secure the additional
handle at the required angle. Tighten the additional
handle.
6. Use
6.1
Depth Stop Setting
(Only for KHEV 5-40 BL)
Release the wing (4) screw. Set the depth stop (5)
to the required drilling depth. Retighten the wing
screw (4).
6.2
Positioning, removing tool
Before inserting, clean tool shank and apply
supplied special grease (accessories: Order
no. 6.31800)! Use only SDS-max tools.
Positioning tool:
Turn tool and insert until it engages. The tool is
automatically locked.
Pull on the tool to check that it is correctly
seated. (It must be possible to move the tool a
few centimetres in an axial direction.)
Remove the tool:
Pull the tool lock (6) backwards in direction
indicated by arrow (a) and remove tool (b).
6.3
Setting operating mode and chisel
position
Avoid levering with the machine when a chisel
is fitted.
Do not activate the switch button (7) until the
motor has completely stopped.
Turn the switch button (7) to select the desired
operating mode.
Impact drilling (only for KHEV...)
Chiselling
Setting which enables the chisel to be rotated
to the desired position.
Setting the position of the chisel: The chisel can be
locked in different positions.
- Insert the chisel.
- Turn the knob (7) to the interim position
- Turn the chisel to the required position.
- Turn the switch button (7) to position
- Turn the chisel until it engages.
When a chisel is fitted, only operate the
machine in the chiselling operating mode
6.4
Setting impact force
Press the button (14) to change the impact force
(and the speed) (but not while the motor is running).
Button (14) illuminated: reduced impact force,
reduced speed (approx. 70%)
Button (14) not illuminated: maximum impact
force,
high speed (100%)
The correct setting is found by trial and error.
Example: if work is being completed on soft, brittle
material or if you want to keep breakage to a low
level, work at "reduced impact force".
Use the "maximum impact force" setting for working
with harder materials.
6.5
Switching on and off
Torque setting:
Press the trigger switch (9) to switch on the
machine.
To switch off release the trigger switch (9).
Continuous operation (only in chiselling
mode
):
The machine can be switched to continuous
operation (only in chiselling mode
the (10) button. ( (10) button illuminated.)
To switch off, press the (10) button once again. (
(10) button not illuminated.)
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
both hands using the handles provided, stand
securely and concentrate.
6.6
Metabo VibraTech (MVT)
For reduced vibrations and less stress on the
hands.
Always apply a moderate amount of pressure to the
handle when pushing down the machine and do not
force. Vibrations are reduced most effectively at the
central position (8).
