Removing/Inserting the Quick Change Chuck
(GBH 36 VF-LI Plus)
The SDS-plus quick change chuck 2 can easily be replaced
against the quick change keyless chuck 1 provided.
Removing the Quick Change Chuck (see figure D)
– 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 E)
 Use only model-specific original equipment and pay at-
tention to the number of identification grooves 26.On-
ly quick-change chucks with two or three identification
grooves are permitted. When an unsuitable quick-change
chuck is used, the application tool could fall out during op-
eration.
– 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 25 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.
Changing the Tool (SDS-plus)
Inserting SDS-plus Drilling Tools (see figure F)
The SDS-plus drill chuck allows for simple and convenient
changing of drilling tools without the use of additional tools.
– GBH 36 VF-LI Plus: 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 G)
– Push back the locking sleeve 5 and remove the tool.

Dust Extraction with GDE 16 Plus (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-treat-
ment additives (chromate, wood preservative). Materials
containing 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.
