Inserting SDS-plus Drilling Tools
(see figure E)
The SDS-plus drill chuck allows for simple and con-
venient changing of drilling tools without the use of
additional tools.
H 26-MLS: 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 accu-
racy 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 (H 26-MLS) (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 17 of the quick change
chuck. Open the tool holder by turning the front
sleeve 16 until the tool can be inserted. Tightly hold
the retaining ring 17 and firmly turn the front sleeve
16 in the direction of the arrow until a distinct latch-
ing noise can be heard.
Check the tight seating by pulling the tool.
☞
Note: If the tool holder was opened to the
stop, then the latching noise possibly may be
heard while closing the tool holder and the
tool holder will not close.
In this case, turn the front sleeve 16 once in
the opposite direction of the arrow. After-
wards, the tool holder can be closed (tight-
ened) again.
Turn the mode selector switch 11 to the "drilling"
position.
Removing Drilling Tools without
SDS-plus (H 26-MLS) (see figure H)
Firmly hold the retaining ring 17 of the quick change
chuck. Open the tool holder by turning the front
sleeve 16 in the direction of the arrow until the tool
can be removed.

Dust Extraction with the Extraction Device
(Accessory)
❏ Before any work on the machine itself,
pull the mains plug.
Dusts from materials such as lead-containing coat-
ings, 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 con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, wood pre-
servative). Materials containing asbestos may only
be worked by specialists.
• Use dust extraction whenever possible.
• Provide for good ventilation of the working place.
• It is recommended to wear a P2 filter-class respi-
rator.
Observe the relevant regulations in your country for
the materials to be worked.
Mounting the Extraction Device
(see figure I)
An extraction device (accessory) is required for dust
extraction. When drilling, the extraction device
retracts so that the head of the extraction device is
always positioned close to the surface.
Press the button for depth stop adjustment 12 and
remove the depth stop 13. Press button 12 again
and insert the extraction device from the front into
the auxiliary handle 14.
Connect a vacuum hose to the extraction sleeve 18
of the extraction device.
The vacuum cleaner must be suitable for the mate-
rial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special vac-
uum cleaner.
Adjusting the Drilling Depth on the
Extraction Device (see figure J)
The requested drilling depth X can also be set when
the extraction device is mounted.
Insert the SDS-plus drilling tool to the stop into the
SDS-plus tool holder 3. Otherwise, the movability of
the SDS-plus drilling tool can lead to incorrect
adjustment of the drilling depth.
Loosen wing bolt 22 of the extraction device.
Without switching the power tool on, apply it firmly
to the drilling location. The SDS-plus drilling tool
must face against the surface.
