pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the surface

incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
Ŷ 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.
Ŷ Do not position your body in line with the rotating
wheel.
If kickback occurs, it will propel the cutting unit
upwards toward the operator.
Ŷ 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.
Ŷ 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 wheel breakage.
Ŷ 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.
Ŷ 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.
Ŷ 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
Ŷ Ensure that the product is always used on a stable and
level surface.
Ŷ Always use eye and ear protection when cutting.
Ŷ Use personal protective equipment such as dust mask,
gloves and apron.
Ŷ If there is the risk of falling object, wear helmet or head
protection.
Ŷ 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.
Ŷ Before making a cut, be sure all adjustments are secure.
Ŷ Before performing any adjustment, make sure the tool
is unplugged from the power supply. Failure to unplug
cut-off machine could result in accidental starting
causing possible serious personal injury.
Ŷ Assemble all parts to your cut-off machine before
connecting it to power supply.
Ŷ The product should never be connected to power supply
when you are assembling parts, making adjustments,
installing or removing wheels, or when not in use.
Ŷ Visually inspect the abrasive wheel before every use.
Check the wheel for fissures and cracks. Do not use
damaged abrasive wheel.
Ŷ Do not use saw blades.
Ŷ 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.
Ŷ 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.
Ŷ Do not start your abrasive cut-off machine without
checking for interference between the wheel and the
machine base support. Damage may result to the wheel
if it strikes the machine base support during operation
of the machine.
Ŷ Do not attempt to cut wood or masonry with this cut-
off machine. Never cut magnesium or magnesium alloy
with this machine.

cracks.
Ŷ Always ease the abrasive wheel against the work piece
when starting to cut. A harsh impact can break the wheel.
Ŷ Never cut more than one work piece at a time. Do not
stack more than one work piece on the machine base
at a time.
Ŷ To minimise risk of tipping the machine, always support
long work pieces.
Ŷ Cutting steel will cause sparks. Do not operate in the
presence of combustible or flammable materials.
Ŷ Never leave tool running unattended. Do not leave tool
until it comes to a complete stop. The wheel continues
to rotate after the product is switched off.
Ŷ Always release the power switch and allow the wheel
to stop rotating before raising it out of the work piece.
Ŷ Keep hands away from cutting area. Keep hands away
from wheel. Do not reach underneath work or around
or under the wheel while the wheel is rotating. Do not
