n)
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.
o)
Do not operate the power tool near flammable materials.
Sparks could ignite these
materials.
p)
Do not use accessories that require liquid coolants.
Using water or other liquid
coolants may result in electrocution or shock.
NOTE
：
The above warning does not apply for power tools specifically designed for use with a
liquid system.
4. KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush
or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled power tool to be forced in the direction opposite of
the accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the work-piece, the edge of the
wheel that is entering into the pinch point can dig into the surface of the material causing
the wheel to climb out or kick out. The wheel may either jump toward or away from the
operator, depending on direction of the wheel’s movement at the point of pinching.
Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below.
a)
Maintain a firm grip on the power tool and position your body and arm to allow you to
resist kickback forces. Always use auxiliary handle, if provided, for maximum control
over kickback or torque reaction during start-up.
The operator can control torque
reactions or kickback forces, if proper precautions are taken.
b)
Never place your hand near the rotating accessory.
Accessory may kickback over
your hand.
c)
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.
d)
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.
e)
Do not attach a saw chain woodcarving blade or toothed saw blade.
Such blades
create frequent kickback and loss of control.
5. ADDITIONAL SAFETY INSTRUCTIONS FOR GRINDING AND
CUTTING OFF OPERATIONS
a)
Use only wheel types that are recommended for your power tool and the specific
guard designed for the selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
b)
The grinding surface of center depressed wheels must be mounted below the plane
of the guard lip. An improperly mounted wheel that projects through the plane of the
guard lip cannot be adequately protected.
