lines or call the local utility company for as-
sistance. Contact with electric lines can lead to
fire or electrical shock. Damaging a gas line can re-
sult in an explosion. Penetrating a water pipe will
cause property damage or an electrical shock.
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.
Operate the machine only with the auxiliary handle
I
9.
Secure the workpiece. A workpiece clamped
I
with clamping devices or in a vice is held more se-
cure than by hand.
Place the machine on the nut/screw only when
I
switched off.
Be careful when screwing in long screws; danger
I
of sliding off.
When working with the machine, always hold it
I
firmly with both hands and provide for a secure
stance.
Always switch the machine off and wait until it has
I
come to a standstill before placing it down.
Never allow children to use the machine.

BTI is able to ensure flawless functioning of the ma-
I
chine only if the original accessories intended for it
are used.
Tool Changing (Fig. F–K)
Take care that the dust protection cap 2 is not
damaged when changing tools.
SDS-Plus Tools
The SDS-plus tool is designed to be freely movable.
This causes eccentricity when the machine is off-load.
However, the drill automatically centres itself during
operation. This does not affect drilling precision.
Inserting (Fig.
)
F
Clean and lightly oil the tool before inserting.
Insert the dust-free tool into the tool holder 1 with
twisting until it latches.
The tool locks itself. Check the locking by pulling on
the tool.
Removing (Fig.
)
G
Pull the locking sleeve 3 to the rear (a) and hold while
removing the tool (b).

Tools without SDS-plus
Do not use tools without SDS-plus for hammer
drilling or chiselling!
To work with tools without SDS-plus (e.g., drills with
cylindrical shafts), a drill chuck 11 with a SDS-plus
chuck shaft 12 (optional accessory) must be inserted
into the tool holder (Fig.
Insert the dust-free, assembled chuck into the tool
holder 1 with twisting until it latches (Fig.
The chuck locks itself. Check the locking by pulling on
the chuck.
Srewdriver Bits (Fig.
For screwdriver bits, use the SDS-plus adapter 13 (op-
tional accessory).
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. Ma-
chines designated for 230 V can also be operated with
220 V.
Switching On/Off
To switch on the machine, press the on/off switch 5.
Lock the depressed on/off switch 5 by pressing the
lock-on button 4.
For reasons of safety, on/off switch 5 cannot be
locked with locking button 4 in left rotation.
To switch off the machine, release the on/off switch
5 or push and then release it.
Working Instructions (Fig. L–N)
Auxiliary Handle (Fig.
For safety reasons, the machine should be
I
used only with the auxiliary handle 9.
By rotating the auxiliary handle 9 to a comfortable po-
sition, a fatigue-free and therefore safe working posi-
tion can be achieved.
To rotate the auxiliary handle 9, first release the handle
by turning it counter-clockwise.
Then retighten the auxiliary handle 9.
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.
