Service
 Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Hammer Safety Warnings
 Wear ear protectors. Exposure to noise can cause hear-
ing loss.
 Use auxiliary handle(s), if supplied with the tool. Loss
of control can cause personal injury.
 Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting ac-
cessory contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the operator an
electric shock.
 When working with the machine, always hold it firmly
with both hands and provide for a secure stance. The
power tool is guided more secure with both hands.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an author-
ised customer service agent. The replacement plug should
have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains sock-
et elsewhere.
Products sold in AUS and NZ only: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.
Additional Safety and Working In-
structions
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
 Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility com-
pany 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 dam-
age.
 Before any work on the machine itself, pull the mains
plug.
1 619 92A 067 | (18.10.13)
 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.
 If the application tool should become blocked, switch
the machine off. Loosen the application tool.
 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.
 For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving, tools without SDS-plus
are used (e.g., drills with cylindrical shank). For these
tools, a keyless chuck or a key type drill chuck are re-
quired.
 GBH 2-28 DFV: Only use quick change chucks with 3
identification grooves (standard delivery scope) or 2
identification grooves (accessory/spare part) – see
figure 1, page 35.
– The quick change chuck is automatically locked. Check
the locking effect by pulling the quick change chuck.
 Inserting SDS-plus Drilling Tools:
 Check the latching by pulling the tool.
 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 in-
serting the tool, pay attention that the dust protection cap
is not damaged.
 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 res-
piratory infections and/or cancer. Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
ble 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.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
 Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam and
lead to loss of control over the power tool.
