Safety Instructions for Cut-Off Machines
1) Cut-Off Machine Safety Warnings
•
Position yourself and bystanders away from the
plane of the rotating wheel.
The guard helps to protect
the operator from broken wheel fragments and accidental
contact with wheel.
•
Use only bonded reinforced wheels for your power
tool.
Just because an accessory can be attached to your
power tool, it does not assure safe operation.
•
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.
•
Wheels must be used only for recommended
applications.
For example: do not grind with the side of
a cut-off wheel. Abrasive cut-off wheels are intended for
peripheral grinding, side forces applied to these wheels
may cause them to shatter.
•
Always use undamaged wheel flanges that are of
correct diameter for your selected wheel.
Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
•
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.
•
The arbour size of wheels and flanges must properly
fit the spindle of the power tool.
Wheels and flanges
with arbour holes 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 damaged wheels.
Before each use, inspect
the wheels for chips and cracks. If the power tool or wheel
is dropped, inspect for damage or install an undamaged
wheel. After inspecting and installing the wheel, position
yourself and bystanders away from the plane of the
rotating wheel and run the power tool at maximum no
load speed for one minute. Damaged wheels will normally
break apart during this test time.
•
Wear personal protective equipment.
Depending
on application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and shop apron capable of stopping
small abrasive 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 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
protective equipment. Fragments of workpiece or of a
broken wheel may fly away and cause injury beyond
immediate area of operation.
•
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 wheel.
•
Regularly clean the power tool’s air vents.
The
motor’s fan can 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.
Do not operate the power tool while placed on
a combustible surface such as wood. 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.
2) Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid stalling
of the rotating wheel which in turn causes the uncontrolled
cutting unit to be forced upwards toward the operator.
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. 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 firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces.
The operator can control upward kickback forces,
if proper precautions are taken.
•
Do not position your body in line with the rotating
wheel.
If kickback occurs, it will propel the cutting unit
upwards toward the operator.
•
Do not attach a saw chain, woodcarving blade,
segmented diamond wheel or toothed saw blade.
Such blades create frequent kickback and loss of control.
damaged, have the power tool repaired before
use.
Many accidents are caused by poorly maintained
power tools.
f )
Keep cutting tools sharp and clean.
Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
g )
Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking
into account the working conditions and the
work to be performed.
Use of the power tool for
operations different from those intended could result
in a hazardous situation.
h )
Keep handles and grasping surfaces dry, clean
and free from oil and grease.
Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
5) Service
a )
Have your power tool serviced by a qualified
repair person using only identical replacement
parts.
This will ensure that the safety of the power
tool is maintained.
