Power Tool Use and Care
r ) 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.
s ) 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.
t ) 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.
u ) 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.
v ) 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.
w ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
x ) 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.
y ) 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.
Battery Tool Use and Care
z ) 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.
aa ) Use power tools only with specifically designated
battery packs. Use of any other battery packs may create
a risk of injury and fire.
ab ) 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.
ac ) 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.
ad ) Do not use a battery pack or tool that is damaged
or modified. Damaged or modified batteries may exhibit
30
unpredictable behaviour resulting in fire, explosion or risk
of injury.
ae ) Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130 °C may cause explosion.
af ) 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.
Service
ag ) 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.
ah ) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
Additional Safety Instructions 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 the 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 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.
It is recommended that the side handle be used at all times.
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 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.
