Changing The Tool - Bosch GBH 2600 Professional Originalbetriebsanleitung

Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus tools are re-
quired that are inserted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drills with cylindrical shank). For these tools, a
keyless chuck or a key type drill chuck are required.
The SDS-plus quick change chuck 2 can easily be replaced
against the quick change keyless chuck 1 provided.
Removing/Inserting the Quick Change Chuck
Removing the Quick Change Chuck (see figure C)
– Pull the lock ring for the quick change chuck 6 toward the
rear, hold it in this position and pull off the SDS-plus quick
change chuck 2 or the quick change keyless chuck 1 to-
ward the front.
– After removing, protect the replacement chuck against
contamination.
Inserting the Quick Change Chuck (see figure D)
– Before inserting, clean the quick change chuck and apply a
light coat of grease to the shank end.
– Grasp the SDS-plus quick change chuck 2 or the quick
change keyless chuck 1 completely with your hand. Slide
the quick change chuck with a turning motion onto the drill
chuck mounting 16 until a distinct latching noise is heard.
– The quick change chuck is automatically locked. Check the
locking effect by pulling the quick change chuck.

Changing the Tool

The dust protection cap 4 largely prevents the entry of drilling
dust into the tool holder during operation. When inserting the
tool, take care that the dust protection cap 4 is not damaged.
A damaged dust protection cap should be changed im-
mediately. We recommend having this carried out by
an after-sales service.
Inserting SDS-plus Drilling Tools (see figure E)
The SDS-plus drill chuck allows for simple and convenient
changing of drilling tools without the use of additional tools.
– Insert the SDS-plus quick change chuck 2.
– Clean and lightly grease the shank end of the tool.
– Insert the tool in a twisting manner into the tool holder until
it latches itself.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus drilling tool can
move freely. This causes a certain radial run-out at no-load,
which has no effect on the accuracy of the drill hole, as the
drill bit centres itself upon drilling.
Removing SDS-plus Drilling Tools (see figure F)
– Push back the locking sleeve 5 and remove the tool.
Inserting Drilling Tools without SDS-plus (see figure G)
Note: 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.
– Insert the quick change keyless chuck 1.

– Firmly hold the retaining ring 18 of the quick change
chuck. Open the tool holder by turning the front sleeve 17
until the tool can be inserted. Tightly hold the retaining ring
18 and firmly turn the front sleeve 17 in the direction of the
arrow until a distinct latching noise can be heard.
– Check the tight seating by pulling the tool.
Note: If the tool holder was opened to the stop, then the latch-
ing noise possibly may be heard while closing the tool holder
and the tool holder will not close.
In this case, turn the front sleeve 17 once in the opposite di-
rection of the arrow. Afterwards, the tool holder can be
closed (tightened) again.
– Turn the mode selector switch 11 to the "drilling" position.
Removing Drilling Tools without SDS-plus (see figure H)
– Firmly hold the retaining ring 18 of the quick change
chuck. Open the tool holder by turning the front sleeve 17
in the direction of the arrow until the tool can be removed.
Dust Extraction with the Dust Extraction Attach-
ment (Accessory)
Dusts from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dusts can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dusts, such as oak or beech dust, are considered as
carcinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable for
the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.
Mounting the Dust Extraction Attachment (see figure I)
For dust extraction, the dust extraction attachment (accesso-
ry) is required. When drilling, the dust extraction attachment
retracts so that the attachment head is always close to the
surface at the drill hole.
– Press the button for depth stop adjustment 12 and remove
the depth stop 13. Press button 12 again and insert the
dust extraction attachment into the auxiliary handle 14
from the front.
– Connect an extraction hose (diameter 19 mm, accessory)
to the extraction sleeve 19 of the dust extraction attach-
ment.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Adjusting the Drilling Depth on the Dust Extraction At-
tachment (see figure J)
The required drilling depth X can also be adjusted when the
dust extraction attachment is mounted.
