Specifications; Standard Accessories - Hitachi CM12Y Handling Instructions Manual

English
e) Do not attach a saw chain woodcarving blade 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 blinding 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.

PRECAUTIONS 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 re-
duced 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.
8. Wear a dust mask
Do not inhale the harmful dusts generated in cutting
operation. The dust can endanger the health of
yourself and bystanders.
