Kickback will propel the tool in direction opposite to
the wheel's movement at the point of snagging.
d) 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.
e) 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.
f) 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.
g) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool 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.
h) 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.
i) Support panels or 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.
j) Use extra caution when making a "pocket cut" into
existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.

PRECAUTION ON USING DISC CUTTER
1. Never attach any tool except the diamond wheel or
cutting wheel as specified by the manufacturer (see
optional accessories).
Do not operate the cutter while applying water.
2. Always check the diamond wheel before starting the
machine. If it is cracked, broken or bent, do not use
it. Carefully start the machine to check for other
abnormalities.
3. Using the diamond wheel to cut metal will shorten
its service life or will result in breakage. Never use
the diamond wheel to cut metal.
4. Start working only when maximum rotation speed
is reached.
5. Excessive force overloads the motor and reduces
working efficiency and service life. Always cut
concrete, tile or stone with a cutting depth of 50mm
or less. If the cutting depth is more than 50mm,
cut the workpiece 2 or 3 times. If the workpiece is
cut with a cutting depth of more than 50mm, the
service life of the diamond wheel will be reduced
and the motor may seize.
6. Do not use this machine to cut asbestos.
7. In operations using a cutting wheel, if flame comes
out, cover the dust collection adapter with a rubber
cap and be sure to wear protective glasses.
