Specifications; Standard Accessories - Hitachi CM 12Y Operating Instructions Manual

English
The operator can control torque reactions or kickback
forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in line with the rotating
wheel.
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 specifi ed 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 effi ciency 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 fl ame comes out,
cover the dust collection adapter with a rubber cap and
be sure to wear protective glasses.
