Changing The Tool - Bosch PBH 2800 RE Bedienungsanleitung

Inserting the Quick Change Chuck (see figure F)
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 23 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 immediately. We recommend having
this carried out by an after-sales service.
Inserting SDS-plus Drilling Tools (see figure G)
The SDS-plus drill chuck allows for simple and conven-
ient changing of drilling tools without the use of addi-
tional tools.
PBH 3000-2 FRE: 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 H)
Push back the locking sleeve 5 and remove the tool.
Inserting Drilling Tools without SDS-plus into
the Key Type Drill Chuck (PBH 2800 RE)

ling.
Insert the key type drill chuck 20.
Open the key type drill chuck 20 by turning until the tool
can be inserted. Insert the tool.
Insert the chuck key into the corresponding holes of the
key type drill chuck 20 and clamp the tool uniformly.
Turn the mode selector switch 12 to the "drilling" posi-
tion.
Removing Drilling Tools without SDS-plus from

Dust Extraction with the Dust
Extraction Attachment (Accessory)
Mounting the Dust Extraction Attachment
(see figure K)
For dust extraction, the dust extraction attachment
(accessory) is required. When drilling, the dust extrac-
tion attachment retracts so that the attachment head is
always close to the surface at the drill hole.
Press the button for depth stop adjustment 15 and
remove the depth stop 18. Press button 15 again and
insert the dust extraction attachment into the auxiliary
handle 17 from the front.
Connect an extraction hose (diameter 19 mm, acces-
sory) to the extraction sleeve 26 of the dust extraction
attachment.
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.
