Additional Safety Information - DeWalt D25911 Instruction Manual

g ) If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust‑related hazards.
h ) Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
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 remove the battery pack, if detachable, from
the power tool before making any adjustments,
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 and accessories. Check
for misalignment or binding of moving parts,
breakage 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 instructions, taking
into account the working conditions and the
work to be performed. Use of the power tool for
operations different from those intended could result in
a hazardous situation.
h ) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
5) Service
a ) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power tool
is maintained.
Additional Safety Instructions for
Demolition Hammers
• Wear ear protectors. Exposure to noise can cause
hearing loss.
• Use auxiliary handles 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
accessory contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the operator
an electric shock.
• Be certain that the material being operated
on does not conceal electric or gas service and
that their locations have been verified with the
utility companies.
• Keep a firm grip on the tool at all times. Do not
attempt to operate this tool without holding it with both
hands. Operating this tool with one hand will result in
loss of control. Breaking through or encountering hard
materials such as re‑bar may be hazardous as well. Tighten
the side handle securely before use.
• Do not recondition accessories yourself. Chisel
reconditioning should be done by a qualified specialist.
Improperly reconditioned accessories could cause injury.
• Wear gloves when operating tool or changing
bits. Accessible metal parts on the tool and bits may
get extremely hot during operation. Small bits of broken
material may damage bare hands.
• Never lay the tool down until the bit has come to a
complete stop. Moving bits could cause injury.
• Do not strike jammed bits with a hammer to dislodge
them. Fragments of metal or material chips could dislodge
and cause injury.
• Ensure the chisel is secured in place before operating
the tool.
• In cold‑weather conditions or when the tool has not
been used for a longer period of time, let the tool run
with no load for several minutes before use.
• When working above ground level ensure the area
below is clear.
• Do not touch the chisel or the parts close to the
chisel immediately after operation, as they may be
extremely hot and cause burns to the skin.
• Always direct the power cable to the rear, away from
the chisel.
Do not operate this tool for long periods of time.
•
Vibration caused by hammer action may be harmful to
your hands and arms. Use gloves to provide extra cushion
and limit exposure by taking frequent rest periods.
