Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the
accessory must fit the locating diameter of the
flange.
Accessories that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory is dropped, inspect for damage or install
an undamaged accessory. After inspecting
and installing an accessory, position yourself
and bystanders away from the plane of the
rotating accessory and run the power tool at
maximum no-load speed for one minute.
Dam-
aged accessories will normally break apart during this test
time.
Wear personal protective equipment. Depend-
ing on application, use face shield, safety gog-
gles or safety glasses. As appropriate, wear
dust mask, hearing protectors, gloves and
shop apron capable of stopping small abra-
sive 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 protective equipment.
Fragments of workpiece or of a broken accessory may fly
away and cause injury beyond immediate area of opera-
tion.
Hold power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting accessory may contact hid-
den wiring.
Cutting accessory contacting a “live” wire
may make exposed metal parts of the power tool “live”
and shock the operator.
Position the cord clear of the spinning acces-
sory.
If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning
wheel.
Never lay the power tool down until the acces-
sory has come to a complete stop.
The spinning
wheel may grab the surface and pull the power tool out
of your control.
Do not run the power tool while carrying it at
your side.
Accidental contact with the spinning acces-
sory 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 cool-
ants.
Using water or other liquid coolants may result in
electrocution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. 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 workpiece, 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 pinch-
ing. Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
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.
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.
Kick-
back will propel the tool in direction opposite to the
wheel’s movement at the point of snagging.
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.
