Wear personal protective equipment. Depending on appli-
cation, use face shield, safety goggles or safety glasses.
Where appropriate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stopping small
abrasive or workpiece fragments. The eye protection
must be capable of stopping flying debris generated by
various operations. The dust mask or respirator must be
capable of filtrating particles generated by your opera-
tion. Prolonged exposure to high intensity noise may
cause hearing loss.
Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal pro-
tective equipment. Fragments of workpiece or of a bro-
ken accessory may fly away and cause injury beyond
immediate area of operation.
Hold the power tool by insulated gripping surfaces only,
when performing an operation where the cutting acces-
sory 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.
Always hold the power tool firmly when starting it. The
reaction torque of the motor, as it accelerates to full
speed, can cause the power tool to twist.
If possible, use clamps to fasten or affix the workpiece.
Never hold a small workpiece in one hand and the power
tool in the other hand while in use. Clamping small work-
pieces allows you to use both hands for better control
the power tool. Round material such as dowel rods, pipes
or tubing have a tendency to roll away while being cut,
and may cause the application tool to jam or bind and be
thrown toward you.
Keep the connection cable away from rotating application
tools. When losing control over the machine, the mains
cable can be cut through or get caught, and your hand or
arm can come in contact with the rotating application
tool.
Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your con-
trol.
After changing application tools or making adjustments
on the tool, tighten the collet nut, chuck or any other fas-
tening elements. Loose fastening elements can unexpect-
edly misadjust and lead to loss of control; unfastened,
rotating components will be violently thrown.
Do not run the power tool while carrying it at your side.
Accidental contact with the spinning accessory could snag
your clothing, pulling the accessory into your body.
Regularly clean the power tool's air vents. The motor's
fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Using
water or other liquid coolants may result in electrocution
or shock.
Further safety warnings for all applications
Kickback and related warnings
Kickback is the sudden reaction to a pinched or snagged
rotating application tool, such as a grinding wheel, sand-
ing belt, wire brush, etc. Pinching or snagging causes the
rotating application tool to rapidly stop. This causes an
uncontrolled power tool to be forced in the direction
opposite of the application tool's rotation direction.
For example, if a grinding wheel is snagged or pinched in
the workpiece, the edge of the grinding wheel that is
entering into the workpiece can be caught, causing the
grinding wheel to break out or cause kickback. The grind-
ing wheel may either jump toward or away from the
operator, depending on the direction of the wheel at the
point of blocking. Grinding wheels can also break under
these conditions.
Kickback is the result of power tool misuse or incorrect
operating procedures. It can be avoided by taking proper
precautions as described below.
Maintain a firm grip on the power tool and position your
body and arms to allow you to resist kickback forces. The
operator can control torque reactions or kickback forces,
if proper precautions are taken.
Use special care when working corners, sharp edges, etc.
Avoid bouncing and snagging the accessory. Corners,
sharp edges or bouncing have a tendency to snag the
rotating accessory and cause loss of control or kickback.
Do not use toothed saw blades. Such application tools
create frequent kickback or loss of control over the
power tool.
Always feed the application tool into the material in the
same direction as the cutting edge is exiting from the
material (which is the same direction as the chips are
thrown). Guiding the power tool in the wrong direction
causes the cutting edge of the application tool to climb
out of the workpiece and pull the tool in the direction of
this feed.
Always clamp the workpiece when using rotating files,
cutting discs, carbide (TC) or high-speed grinding tools.
These application tools will pinch or grab if they become
slightly canted in the groove, and can kickback. When a
cutting disc grabs, the disc itself usually breaks. When
rotating files, carbide (TC) or high-speed grinding tools
pinch or grab, the tool insert may jump from the groove
and you could lose control of the tool.
Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
Do not position your body in the area where power tool
will move if kickback occurs. Kickback will propel the
tool in direction opposite to the wheel's movement at
the point of snagging.
