s) Do not use diamond wheels that require liquid coolants.
Using water or other liquid coolants may result in electrocution or
shock.
t) Do not use accessories which are not specifically designed
and recommended by the tool manufacturer. Just because the
accessory can be attached to your power tool, it does not assure safe
operation.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating
wheel, diamond wheel. Pinching or snagging causes rapid stalling
of the rotating diamond wheel which in turn causes the uncontrol-
led power tool to be forced in the direction opposite of the diamond
wheel’s rotation at the point of the binding.
For example, if an diamond 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 diamond-
wheel to climb out or kick out. The diamond wheel may either jump
toward or away from the operator, depending on direction of the
diamond wheel’s movement at the point of pinching. Diamond
wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect opera-
ting procedures or conditions and can be avoided by taking proper
precautions as given below.
a) Maintain a firm grip on the power tool and position your
body and arm to allow you to resist kickback forces. Always
use auxiliary handle, if provided, for maximum control over
kickback or torque reaction during start-up. The operator can
control torque reactions or kickback forces, if proper precautions
are taken.
b) Never place your hand near the rotating diamond wheel.
Diamond wheel may kickback over your hand.
c) Do not position your body in line with the rotating dia-
mond wheel. Kickback will propel the tool in direction opposite to
the diamond wheel’s movement at the point of snagging.
d) Use special care when working corners, sharp edges etc.
Avoid bouncing and snagging the diamond wheel. Corners,
sharp edges or bouncing have a tendency to snag the rotating
diamond wheel and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving blade or toothed
saw blade. Such blades create frequent kickback and loss of control.
Safety Warnings Specific for Diamond Cutting-Off Operations:
a) Use only diamond wheels that are recommended for
abrasive cutting-off operations.
b) Do not use worn down diamond wheels from larger power
tools. Diamond wheel intended for larger power tool is not suitable
for the higher speed of a smaller tool and may burst.
Additional Safety Warnings Specific for Abrasive Cutting-Off
Operations:
a) Do not “jam” the diamond wheel or apply excessive
pressure. Do not attempt to make an excessive depth of cut.
Overstressing the diamond wheel increases the loading and suscepti-
bility to twisting or binding of the diamond wheel in the cut and the
possibility of kickback or diamond wheel breakage.
b) Do not position your body in line with and behind the
rotating diamond wheel.
When the diamond wheel, at the point of
operation, is moving away from your body, the possible kickback may
propel the spinning diamond wheel and the power tool directly at you.
c) When diamond wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold the power
tool motionless until the diamond wheel comes to a complete
stop. Never attempt to remove the diamond wheel from the
cut while the diamond wheel is in motion otherwise kickback
may occur. Investigate and take corrective action to eliminate the
cause of wheel binding.
d) Do not restart the cutting operation in the workpiece. Let
the diamond wheel reach full speed and carefully re-enter the
cut. The diamond wheel may bind, walk up or kickback if the power
tool is restarted in the workpiece.
e) Support panels or any oversized workpiece to minimize the
risk of diamond 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.
f) Use extra caution when making a “pocket cut” into existing
walls or other blind areas. The protruding diamond wheel may cut
gas or water pipes, electrical wiring or objects that can cause kickback.
Additional Safety and Working Instructions
Avoid sanding dust hit your body.
Never reach into the danger area of the machine when it is running.
Immediately switch off the machine in case of considerable vibra-
tions or if other malfunctions occur. Check the machine in order to
find out the cause.
Chips and splinters must not be removed while the machine is
running.
WORKING INSTRUCTIONS
Only use and store diamond cutting discs according to the manu-
facturer‘s instructions.
Always use the cutting guard for cutting.
The adjusting nut must be tightened before starting to work with
the machine.
Always use the auxiliary handle.
The workpiece must be fixed if it is not heavy enough to be steady.
Never lead the workpiece to the diamond wheel with your hand.
MAINTENANCE
Use only Milwaukee accessories and Milwaukee spare parts. Should
components need to be replaced which have not been described, please
contact one of our Milwaukee service agents (see our list of guarantee/
service addresses).
If needed, an exploded view of the tool can be ordered. Please state
