g) If devices are provided for the connec-
tion of dust extraction and collection fa-
cilities, ensure these are connected and
properly used. Use of dust collection can
reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the
correct power tool for your application.
The correct power tool will do the job
better and safer at the rate for which it
was designed.
b) Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch
is dangerous and must be repaired.
c) Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjust-
ments, changing accessories, or storing
power tools. Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
d) Store idle power tools out of the reach
of children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for misalign-
ment or binding of moving parts, break-
age of parts and any other condition that
may affect the power tool's operation. If
damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
g) Use the power tool, accessories and tool
bits etc. in accordance with these instruc-
tions, taking into account the working
conditions and the work to be performed.
Use of the power tool for operations differ-
ent from those intended could result in a
hazardous situation.

5) Service
a) Have your power tool serviced by a qual-
ified repair person using only identical
replacement parts. This will ensure that
the safety of the power tool is maintained.

Hammer Safety Warnings

Wear ear protectors. Exposure to noise can
cause hearing loss.
Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal in-
jury.
Hold power tool by insulated gripping sur-
faces, 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.
Use suitable 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 or may cause 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 clamping devices or in a vice is held
more secure than by hand.
Keep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from
light alloys can burn or explode.
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.
Never use the machine with a damaged
cable. Do not touch the damaged cable and
pull the mains plug when the cable is dam-
aged while working. Damaged cables in-
crease the risk of an electric shock.
