Connect machines that are used in the open via a
I
residual current device (RCD) with an actuating
current of 30 mA maximum. Do not operate the
machine in rain or moisture.
Always direct the cable to the rear away from the
I
machine.
Use suitable detectors to find hidden utility
I
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.
Operate the machine only with the auxiliary handle
I
12.
Secure the work piece. A work piece clamped
I
with clamping devices or in a vice is held more se-
curely 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.
I
BTI is able to ensure flawless functioning of the ma-
I
chine only if the original accessories intended for it
are used.
Changing the Drill Chuck
Do not carry the machine by the replace-
ment drill chuck!
The SDS-plus replacement drill chuck can be easily
exchanged for the quick clamping replacement drill
chuck supplied with the drill hammer.
Hammer drilling and chiselling is possible only with
SDS-plus tools that can be inserted in the SDS-plus
replacement drill chuck.
Drilling and screwdriving is also possible with tools that
are not SDS-plus (e.g., round shaft drills, screwdriver
bits) which are clamped in the quick clamping replace-
ment drill chuck.

Removing the Replacement Drill Chuck
(Fig.
)
A
Danger of injury! Before removing the re-
placement drill chuck, always remove the
tool or bit.
Grasp the locking ring 6 of the SDS-plus replacement
drill chuck and pull forcefully in the direction of the ar-
row. The replacement drill chuck comes off.
Attaching the Replacement Drill Chuck
(Fig.
)
B
Grasp the quick clamping replacement drill chuck with
the whole hand. Place it with a twisting motion on the
chuck holder until it can clearly be heard to latch. The
replacement drill chuck locks itself.
Check locking by pulling on the replacement drill
chuck.
Make replacements in a corresponding manner.
Maintenance of the Replacement Drill Chucks
Keep the connecting parts free of dust. Lubrication is
not necessary.
Tool Changing (Fig. C–G)
Take care that the dust protection cap 4 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.
Clean and lightly oil the tool before inserting.
Insert the dust-free tool into the tool holder 3 with
twisting until it latches.
The tool locks itself. Check the locking by pulling on
the tool.
Removing (Fig.
Pull the locking sleeve 5 to the rear (a) and hold while
removing the tool (b).
Srewdriver Bits (Fig.
For screwdriver bits, use the SDS-plus adapter 14 (op-
tional accessory).
