Tools without SDS-plus
Do not use tools without SDS-plus for hammer
drilling or chiselling!
Tool Insertion (Fig.
F
Hold the holding ring 16 firmly and turn the front sleeve
15 until the tool holder is open wide enough.
Insert the tool, hold firmly the holding ring 16 and turn
the sleeve 15 in the direction of the arrow until it latch-
es. Then clamp the tool by continuing to turn forcefully
until ratcheting sounds can clearly be heard.
Check the seating by pulling on the tool.
Note:
After opening the tool holder to the stop, it can happen
during the subsequent closing that the functional
ratcheting sound is heard and the tool holder does not
close.
By turning the sleeve 15 opposite to the direction of
the arrow, this ratcheting sound is switched off and the
tool holder can be closed.
For screwdriver bits, insert a commercially available bit
holder. Insert the screwdriver bits into the bit holder.
Use only screwdriver bits that fit the screw heads.
Screwdriver bits may also be inserted without a bit
holder.
Tool Removal (Fig.
G
To remove a tool from the quick clamping replacement
drill chuck, hold firmly the holding ring 16 and turn the
front sleeve 15 in the direction of the arrow until the
tool can be removed.
System Accessories
For accessory insertion tools, see the BTI Catalogue.
Putting into Operation
Ensure that the mains voltage is correct!
The voltage of the power source must agree with the
value given on the nameplate of the machine.
Machines designated for 230 V can also be operated
with 220 V.
Switching On/Off
To switch on the machine, press the on/off switch 8.
Lock the depressed on/off switch 8 by pressing the
lock-on button 7.
For reasons of safety, on/off switch 8 cannot be
locked with locking button 7 in left rotation.
To switch off the machine, release the on/off switch
8 or press and then release it.

Working Instructions (Fig. H–K)
Auxiliary Handle (Fig.
For safety reasons, the machine should be
I
used only with the auxiliary handle 12.
By rotating the auxiliary handle 12 to a comfortable po-
sition, a fatigue-free and therefore safe working posi-
tion can be achieved.
To rotate the auxiliary handle 12, first release the han-
dle by turning it counter-clockwise.
Then retighten the auxiliary handle 12.
Overload Clutch
If the drill bit becomes jammed or caught, the drive to
the drill spindle is interrupted. Because of the forces
that occur as a result, always hold the machine se-
curely with both hands and take a firm stance.
Depth Stop (Fig.
Loosen the winged screw 17 on the auxiliary handle
12. Adjust the drilling depth t on the depth stop 13.
Retighten the winged screw.
Dust Vacuuming/Vacuuming Attachment
Dust produced while working can be detrimental to
I
health, inflammable or explosive. Suitable protec-
tion measures are required.
Examples: Some dusts are considered to be carci-
nogenic. Use suitable dust/chip extraction and
wear a dust protection mask.
Light metal dust can burn or explode. Always keep
I
the work place clean since material mixtures are
especially dangerous.
The machine can be connected directly to the socket
of an all-purpose vacuum cleaner with remote start-
ing. The vacuum cleaner starts automatically when
the machine is switched on.
Mount the vacuuming attachment (optional accessory)
and connect the vacuum cleaner.
The vacuuming attachment is spring loaded up to the
preselected drilling depth. In this manner, the vacu-
uming attachment head is always held close to the
surface.
Setting the Speed (Fig.
By increasing or decreasing the pressure on the on/off
switch 8, the speed can be continuously controlled
during operation.
Advantages:
–
Slow starting of holes, e.g., on smooth surfaces or
tiles
–
No sliding off of the drill when starting the hole
–
No splintering of the hole.
The speed must be selected according to the operat-
ing mode, the material to be worked and the diameter
of the drill.
See Operating Modes for recommended values.
