Working Instructions (Fig. K–N)
Place the machine on the nut/screw only
s
when it is switched off.
Auxiliary Handle (Fig.
)
K
For safety reasons, the machine should be
s
used only with the auxiliary handle 14.
By rotating the auxiliary handle 14 to a comfortable po-
sition, a fatigue-free and therefore safe working posi-
tion can be achieved.
Loosen the winged screw 13 on the auxiliary handle
14. Swing the grip to a new position. Retighten the
winged screw.
Overload Clutch
If the insertion tool becomes caught or jammed, the
drive to the drill spindle is interrupted. As a result of the
forces that occur, always hold the machine firmly
with both hands and provide for a sure footing.
Depth Stop (Fig.
)
L
With the depth stop 15, the drilling depth t can be set.
Press the button 12 and pull out the depth stop to the
tip of the drill. Read the value from the scale 22, sub-
tract the desired drilling depth t and set the resulting
value on the depth stop scale.
Dust Vacuuming/Vacuuming Attachment
Take protective measures when dust is pro-
s
duced while working that is detrimental to
health, combustible or explosive. For example:
Some dusts are considered to be carcinogenic. Use
dust/chip extraction and wear a protective mask.
Keep your workplace clean. Material mixtures
s
are especially dangerous. Light metal dust can
burn or explode.
The machine can be connected directly to the socket
of a Bosch all-purpose vacuum cleaner with remote
starting. 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 vacuum-
ing attachment head is always held close to the surface.
Setting the Speed (Fig.
M
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.

Speed Pre-Selection (Fig.
With the speed regulator 9, the required highest speed
can be pre-set.
As a result of this limitation, the on/off switch can be
pressed only to the pre-set highest speed.
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.
Operating Modes (Fig. O–S)
The operation of the gearbox for each application is
set with the mode selection switch 11:
The operating mode selector switch may be ac-
tuated only at a standstill.
Do not use tools without SDS-plus for hammer
drilling or chiselling!
The following table shows how the operating mode
selector switch 11, the right/left rotation switch 10 as
well as the speed regulator 9 are to be set for the var-
ious operating modes (See fold-out page for figures):
