person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
Hammer Safety Warnings
u Wear ear protectors. Exposure to noise can cause hearing
loss.
u Use auxiliary handle(s), if supplied with the tool. Loss
of control can cause personal injury.
u Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting
accessory contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the operator an
electric shock.
Additional Safety and Working
Instructions
u Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate
of the machine.
u Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility company
for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property damage.
u Firmly tighten the auxiliary handle, hold the machine
firmly with both hands while working and keep proper
footing and balance at all times. The machine is securely
guided with both hands.
u Select the correct operating mode and the suitable
application tool for the material to be worked.
u Insert the SDS-max application tool: Check the latching
by pulling the tool.
u Replace a damaged dust protection cap immediately.
The dust protection cap largely prevents the penetration of
drilling dust into the tool holder during operation. When
inserting the tool, pay attention that the dust protection cap
is not damaged.
u Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health and cause allergic reactions, lead to
respiratory infections and/or cancer. 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.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
u If the application tool should become blocked, switch
the machine off. Loosen the application tool.
u Before switching on the power tool, make sure that the
application tool moves freely. When switching on with a
blocked drilling tool, high torque reaction can occur.
