PERSONAL SAFETY
Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use tool while
tired or under the influence of drugs, alcohol, or medica-
tion. A moment of inattention while operating power tools may
result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry.
Contain long hair. Keep your hair, clothing, and gloves away
from moving parts. Loose clothing, jewelry, or long hair can be
caught in moving parts. Air vents often cover moving parts and
should also be avoided.
Avoid accidental starting. Be sure switch is off before plug-
ging in. Carrying tools with your finger on the switch or plugging
in tools that have the switch on invites accidents.
Remove adjusting keys or wrenches before turning the tool
on. A wrench or a key that is left attached to a rotating part of
the tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all
times. Proper footing and balance enables better control of the
tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust
mask, non-skid safety shoes, hard hat, or hearing protection
must be used for appropriate conditions.
TOOL USE AND CARE
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.
Do not force tool. Use the correct tool for your application.
The correct tool will do the job better and safer at the rate for
which it is designed.
Do not use tool if switch does not turn it on or off. Any tool
that cannot be controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing the tool.
Such preventative safety measures reduce the risk of starting
the tool accidentally.
Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and
clean. Properly maintained tools, with sharp cutting edges are
less likely to bind and are easier to control.
Check for misalignment or binding of moving parts, break-
age of parts, and any other condition that may affect the
tool’s operation. If damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the manu-
facturer for your model. Accessories that may be suitable for
one tool, may become hazardous when used on another tool.
SERVICE
Tool service must be performed only by qualified repair
personnel. Service or maintenance performed by unqualified
personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts.
Follow instructions in the Maintenance section of this man-
ual. Use of unauthorized parts or failure to follow maintenance
instructions may create a risk of electric shock or injury.
