DeWalt DW235G User Manual

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 medication. 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 switches before turning the tool on.
A wrench or 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, breakage
of parts, and any other condition that may affect the tools
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 manufac-
turer 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 manu-
al. Use of unauthorized parts or failure to follow Maintenance
Instructions may create a risk of electric shock or injury.
Additional Safety Rules
• Hold tool by insulated gripping surfaces when performing an
operation where the cutting tools may contact hidden wiring
or its own cord. Contact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
• Keep handles dry, clean, free from oil and grease. It is recom-
mended to use rubber gloves. This will enable better control
• DO NOT TOUCH ANY METAL PARTS OF THE TOOL when
drilling or driving into walls, floors or wherever live electrical
wires may be encountered. Hold the tool only by insulated
grasping surfaces to prevent electric shock if you drill or drive into
a live wire.
