Concrete planer/grinder safety warnings
Safety Warnings Common for Concrete planing,
Grinding, Sanding, Wire Brushing, or Abrasive
Cutting-Off Operations:
1.
This power tool is intended to function as a
concrete planer, grinder, sander, wire brush or
cut-off tool. Read all safety warnings, instruc-
tions, illustrations and specifications provided
with this power tool.
Failure to follow all instruc-
tions listed below may result in electric shock, fire
and/or serious injury.
2.
Operations such as polishing are not recom-
mended to be performed with this power tool.
Operations for which the power tool was not designed
may create a hazard and cause personal injury.
3.
Do not use accessories which are not specifi
-
cally designed and recommended by the tool
manufacturer.
Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
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 maximum
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 sur-
faces 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 could give the operator an electric shock.
11.
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 accessory.
12.
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.
13.
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.
14.
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.
15.
Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
16.
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 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.
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.
