◦operation and
◦maintenance of the equipment (insofar as this maintenance has not been
contractually taken over by RÖHM).
▪caused by technical operating conditions unknown to RÖHM (e.g.
chemical or electrolytic influences) and/or machine specifications.
▪caused by natural wear.
▪caused by force majeure.
▪caused by incorrect operation of all types or by incorrect use or opera-
tion of the drill chuck. This also includes loading beyond the specified
load limits (e.g. speed, pressure, force, etc.).
This also includes damage caused

Maximum protection of personnel and the environment from dangers and
trouble-free operation is only possible when all safety instructions and
warnings in this operating manual are observed.
2.1 Intended Use
The drill chuckEXTRA-RV may only be operated with hand-held corded
drills and cordless drills with and without a spindle stop. To operate on a
machine without a spindle stop, a version with a holding ring is recommen-
ded.
Only suitable rotationally symmetric tools may be clamped in the drill chuck-
EXTRA-RV.
The permissible usage and environmental conditions must be observed
(Technical data [}11]).
2.2 Improper Use
If the drill chuck is operated for a purpose other than the intended use as
specified in this Operating manual, this is deemed to be improper use.
Any utilisation beyond the scope of the “intended use” poses risks and is
not approved by RÖHM.
Improper use refers to the following:
▪Use of the drill chuck to clamp unsuitable materials (compressible ma-
terials);
▪Clamping and releasing the drill chuck with an aid.
▪Use of the drill chuck with missing or damaged components.
▪Use of the drill chuck as load-bearing equipment, workpiece chuck or
holding device, e.g. gripper;
▪Loading of the drill chuck beyond the defined limits;
▪rotation with the workpiece inserted but not clamped;
▪clamping of rotating workpieces with a great imbalance;
▪Assembly of the drill chuck and accessory parts with incorrect torque
(see Disassembly/assembly of the drill chuck [}13]).
▪Operation with modifications not approved by the manufacturer.

For clamping/releasing, the clamping sleeve (3) is rotated in the direction
shown on the disk (1) or the clamping sleeve. For locking, the clamping
sleeve is rotated in the “ZU (CLOSED)” direction of rotation until further ro-
tation is no longer possible. The clamping jaws (2) fix the clamped tool in
place. In machines without a spindle stop, the holding ring (4) is used for
holding during clamping/releasing.
