Setting The Drilling Depth - Bosch GBH 2-26 E PROFESSIONAL Instrucciones De Servicio

Tools without SDS-plus (GBH 2-26 DFR)
Do not use tools without SDS-plus for hammer
drilling or chiselling! Tools without SDS-plus and
their drill chucks are damaged by hammer drilling or
chiselling.
Inserting the Tool (see Fig.
Place on the quick change keyless drill chuck 1 (see
Inserting the Quick Change Drill Chuck).
Hold the holding ring 21 of the quick change keyless
drill chuck fixed. Open the tool holder 3 wide enough
by turning the front sleeve 20 so that the tool can be
inserted.
Continue holding the holding ring 21 fixed and turn the
front sleeve 20 in the direction of the arrow until a
ratcheting sound can be distinctly heard.
Check the firm seating by pulling on the tool.
Note: After opening the tool holder to the stop, the
ratcheting noise can be audible at the subsequent
closing as a result of the functional design and the tool
holder does not close.
In this case, turn the front sleeve 20 once opposite to
the direction of the arrow. The tool holder can then be
closed.
Tool Removal (see Fig.
Hold the holding ring 21 of the quick change keyless
chuck fixed. Open the tool holder by turning the front
sleeve 20 in the direction of the arrow until the tool can
be removed.

Setting the Drilling Depth

(see Fig. )
I
With the depth stop 13, the desired drilling depth t can
be set.
Press the button 12 of the auxiliary handle and insert
the depth stop into the auxiliary handle 14 so that the
grooved side of the depth stop points downward.
Insert the SDS-plus tool to the stop into the tool holder
3. Otherwise, the freedom of motion of the SDS tool
can lead to an incorrect setting of the drilling depth.
Pull out the depth stop so far that the distance be-
tween the drill tip and the tip of the depth stop corre-
sponds to the desired drilling depth t.

Dust Extraction with the Vacuuming
Attachment (Accessory)
Mounting the Dust Extraction Attachment
(see Fig. )
K
For vacuuming dust, a dust extraction attachment (ac-
cessory) is required. While drilling, the dust extraction
attachment springs back so that the vacuuming head
is always held against the drilled surface.
Press the button 12 of the auxiliary handle and remove
the depth stop 13. Press the button 12 again and in-
sert the dust extraction attachment from the front into
the auxiliary handle 14.
Connect a vacuum hose (19 mm Ø, accessory) to the
opening of the dust extraction attachment.
The vacuum cleaner (e.g., GAS ...) must be suitable
for the material to be worked.
When vacuuming dry dust that is especially detrimen-
tal to health or carcinogenic, use a special vacuum
cleaner.
Setting the Drilling Depth on the Dust Extrac-
tion Attachment (see Fig.
The desired drilling depth t can also be set with the
dust extraction attachment mounted.
Insert the SDS-plus tool to the stop into the tool holder
3. Otherwise, the freedom of motion of the SDS tool
can lead to an incorrect setting of the drilling depth.
Loosen the winged screw 25 on the dust extraction at-
tachment.
Place the machine (without switching on) firmly on the
surface to be drilled. The SDS-plus tool must rest
against the surface.
Slide the guide tube 26 of the dust extraction attach-
ment in its holder so that the dust extraction attach-
ment head rests against the surface to be drilled. Do
not slide the guide tube 26 any further over the tele-
scope tube 24 than necessary so that as large a part
as possible of the scale on the telescope tube 24 re-
mains visible.
Retighten the winged screw 25. Loosen the clamping
screw 22 on the depth stop of the dust extraction at-
tachment.
Slide the depth stop 23 on the telescope tube 24 such
that the distance t shown in the Figure
sponds to the desired drilling depth (distance between
the outer end of the guide tube 26 and the inner side
of the depth stop 23).
Retighten the clamping screw 22 in this position.
