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.
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
Do not position your body in line with the rotating wheel. If
kickback occurs, it will propel the cutting unit upwards toward the
Do not attach a saw chain, woodcarving blade, segmented
diamond wheel with a peripheral gap greater than 10 mm or
toothed saw blade. Such blades create frequent kickback and
loss of control.
Do not "jam" the wheel or apply excessive pressure. Do not
attempt to make an excessive depth of cut. Overstressing
the wheel increases the loading and susceptibility to twisting or
binding of the wheel in the cut and the possibility of kickback or
When the wheel is binding or when interrupting a cut for any
reason, switch off the power tool and hold the cutting unit
motionless until the wheel comes to a complete stop. Never
attempt to remove the wheel from the cut while the wheel is
in motion otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of wheel binding.
Do not restart the cutting operation in the workpiece. Let
the wheel reach full speed and carefully re-enter the cut. The
wheel may bind, walk up or kickback if the power tool is restarted
in the workpiece.
Support any oversized workpiece to minimize the risk of
wheel pinching and kickback. Large workpieces tend to sag
under their own weight. Supports must be placed under the
workpiece near the line of cut and near the edge of the workpiece
on both sides of the wheel.
ADDITIONAL SAFETY WARNINGS
Always use eye and ear protection when cutting.
Use personal protective equipment such as dust mask, gloves
and apron. If there is the risk of falling object, wear helmet or head
Ensure that the abrasive cutting-off wheel is correctly fitted and
tightened before use and run the machine at no-load for 30 seconds
in a safe position, and to stop immediately and replace the cutting-off
wheel if there is considerable vibration.
Before making a cut, be sure all adjustments are secure.
Before performing any adjustment, make sure the tool is disconnected
from the power supply. Failure to disconnect the power supply could
result in accidental starting causing possible serious personal injury.
Assemble all parts to your cut-off saw before connecting it to power
The product should never be connected to the power supply when
you are assembling parts, making adjustments, installing or removing
wheels, or when not in use.
Visually inspect the abrasive wheel before every use. Check the wheel
for fissures and cracks. Do not use damaged abrasive wheel.
Do not use saw blades.
Never use a wheel that is too thick to allow outer flange to engage
with the flats on the spindle. Larger wheels will come in contact with
the wheel guards, while thicker wheels will prevent the bolt from
securing the wheel on the spindle. Either of these situations could
result in a serious accident and can cause serious personal injury.
Do not remove the machine's wheel guards. Never operate the
machine with any guard or cover removed. Make sure all guards are
operating properly before each use.
Do not start your cut-off saw without checking for interference
