Inserting and Removing a Tool

Tools are clamped into the fastening head (3) without the use of
a key.
Inserting a Tool
Attention! Risk of injury by electric current. Unplug the
device from the power socket before making any ad‑
justments (such as mounting or removing hand grips,
making adjustments, replacing drill bits, etc.)!
Make sure the tool shank (9) is clean and lubricate it with a lubri-
cant designed for this purpose.
When inserting a tool into the fastening head, there is no need
to push in the securing sleeve. Always slowly rotate the tool until
it clips into the guiding grooves. Then, check whether the tool is
fastened sufficiently and will not fall out of the fastening head by
slightly moving the tools axis.
When fastening the tool, be careful not to damage the rubber cov-
er (5) that protects the fastening head from dust and coarse dirt.
Immediately replace the rubber cover with a new one if it becomes
damaged!
Removing a Tool
Pull the securing sleeve (4) towards you and pull out the tool.

CVS Anti-vibration Grip

The electro-pneumatic breaker EKS  3 is equipped with an ergo-
nomic composite grip (8) that is fitted with an anti-vibration joint
at the attachment point to the gearbox. This ensures vibrations are
absorbed and prevents them from having any negative impact on
the operator's arm.

Tips for Use

Use protective glasses and ear protection.
Do not press too hard onto the drilling hammer. It will not lead to
any significant increase in its effectiveness.
Always work with the detachable handgrip (7) mounted.
Before turning the device on, check that the function switch (2) is
set to the desired mode.
Long‑term Storage
After the device has been stored for an extended period of time, it
may not operate at full capacity right from the start when in impact
drilling mode. It is a common problem caused by hardened lubri-
cant in the impact drilling mechanism. Leave the device in impact
