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) Battery Tool Use and Care
a ) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used
with another battery pack.
b ) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
c ) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or a fire.
d ) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
e ) Do not use a battery pack or tool that is
damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior resulting
in fire, explosion or risk of injury.
f ) Do not expose a battery pack or tool to
fire or excessive temperature. Exposure to
fire or temperature above 265 °F (130 °C) may
cause explosion.
g ) Follow all charging instructions and do not
charge the battery pack or tool outside the temperature range specified in the instructions.
Charging improperly or at temperatures outside the
specified range may damage the battery and increase
the risk of fire.
6) 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.
b ) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
Specific Safety Rules for Rotary Hammers
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 injury.
• Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring. 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 drilled/
demolished does not conceal electric or gas service
and that their locations have been verified with the
utility companies.
• Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and
may lead to loss of control.
• Wear safety goggles or other eye protection.
Hammering operations cause chips to fly. Flying particles
can cause permanent eye damage. Wear a dust mask
or respirator for applications that generate dust. Ear
protection may be required for most applications.
• 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.
Additional Safety Rules for Rotary Hammers
• 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.
• Do not recondition bits yourself. Chisel reconditioning
should be done by an authorized specialist. Improperly
reconditioned chisels could cause injury.
• Accessories and tool may get hot during operation.
Wear gloves when handling them if performing heat
producing applications such as hammerdrilling and
drilling metals.
• 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.
Slightly worn chisels can be resharpened
•
by grinding.
• Do not overheat the bit (discoloration) while
grinding a new edge. Badly worn chisels require
reforging. Do not reharden and temper the chisel.
• Do not use this tool to mix or pump easily
combustible or explosive fluids (benzine,
alcohol, etc.).
• Do not mix or stir inflammable liquids
labelled accordingly.
