Milwaukee 5211 Grinder User Manual


 
4 5
Wear personal protective equip-
ment. Depending on application, use
face shield, safety goggles or safety
glasses. As appropriate, wear dust
mask, hearing protectors, gloves and
work shop apron capable of stopping
small abrasive or workpiece fragments.
The eye protection must be capable of
stopping ying debris generated by
various operations. The dust mask or
respirator must be capable of ltrating
particles generated by your operation.
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 protec-
tive equipment. Fragments of workpiece
or of a broken accessory may y away
and cause injury beyond immediate area
of operation.
Hold power tool by insulated gripping
surfaces only, when performing an
operation where the cutting accessory
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 shock the operator.
Position the cord clear of the spinning
accessory. If you lose control, the cord
may be cut or snagged and your hand
or arm may be pulled into the spinning
accessory.
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 control.
Do not run the power tool while carrying
it at your side. Accidental contact with the
spinning accessory could snag your cloth-
ing, 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 accu-
mulation of powdered metal may cause
electrical hazards.
Do not operate the power tool near
ammable 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.
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 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, depend-
ing 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.
Maintain a rm grip on the power tool
and position your body and arm to
allow you to resist kickback forces. Al-
ways 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 kick back 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 move-
ment at the point of snagging.
Use special care when working cor-
ners, 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 attach a saw chain woodcarv-
ing blade or toothed saw blade. Such
blades create frequent kickback and loss
of control.
Safety Warnings Speci c for
Grinding
Operations:
Use only wheel types that are rec-
ommended for your power tool and
the speci c guard designed for the
selected wheel. Wheels for which the
power tool was not designed can not be
adequately guarded and are unsafe.
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 operator from
broken wheel fragments and accidental
contact with wheel.
Wheels must be used only for recom-
mended 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 shat-
ter.
Always use undamaged wheel anges
that are of correct size and shape for
your selected wheel. Proper wheel
anges support the wheel thus reducing
the possibility of wheel breakage. Flanges
for cut-off wheels may be different from
grinding wheel anges.
Do not use worn down wheels from
larger power tools. Wheel intended for
larger power tool is not suitable for the
higher speed of a smaller tool and may
burst.
Additional Safety Warnings
Maintain labels and nameplates. These
carry important information. If unreadable
or missing, contact a MILWAUKEE service
facility for a free replacement.
WARNING: Some dust created by power
sanding, sawing, grinding, drilling, and
other construction activities contains
chemicals known to cause cancer, birth
defects or other reproductive harm. Some
examples of these chemicals are:
lead from lead-based paint
• crystalline silica from bricks and cement
and other masonry products, and
• arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equip-
ment, such as those dust masks that are
specially designed to lter out microscopic
particles.
