4.
The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool.
Accessories running faster than
their rated speed can break and fly apart.
5.
The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool.
Incorrectly sized accessories
cannot be adequately guarded or controlled.
6.
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.
7.
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 accessory 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 maxi-
mum no-load speed for one minute.
Damaged acces-
sories will normally break apart during this test time.
8.
Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appropri-
ate, wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping small
abrasive or workpiece fragments.
The eye pro-
tection 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 operation. Prolonged exposure
to high intensity noise may cause hearing loss.
9.
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 operation.
10.
Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden
wiring.
Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
11.
Never lay the power tool down until the acces-
sory has come to a complete stop.
The spinning
accessory may grab the surface and pull the
power tool out of your control.
12.
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.
13.
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.
14.
Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
15.
Do not use accessories that require liquid
coolants.
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 uncon-
trolled 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 move-
ment 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.
1.
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 kick-
back forces, if proper precautions are taken.
2.
Never place your hand near the rotating acces-
sory.
Accessory may kickback over your hand.
3.
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.
4.
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.
5.
Do not attach a saw chain woodcarving blade
or toothed saw blade.
Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations:
1.
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.
2.
The grinding surface of centre 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.
3.
The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed
towards the operator.
The guard helps to protect
the operator from broken wheel fragments, acci-
dental contact with wheel and sparks that could
ignite clothing.
4.
Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel.
Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.
