Always hold the power tool firmly when start-
ing it. The reaction torque of the motor, as it
accelerates to full speed, can cause the power
tool to twist.
If possible, use clamps to fasten or affix the
workpiece. Never hold a workpiece in one
hand and the power tool in the other hand
while in use. Clamping workpieces allows
you to use both hands for better control the
power tool.
Never lay the power tool down until the acces-
sory has come to a complete stop. The spin-
ning accessory may grab the surface and pull
the power tool out of your control.
Do not run the power tool while carrying it at
your side. Accidental contact with the spin-
ning accessory could snag your clothing, pull-
ing the accessory into your body.
Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside the
housing and excessive accumulation of pow-
dered metal may cause electrical hazards.
Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Secure the work piece firmly. A work piece
that is gripped tightly in a clamping device or
vice, is more secure than if held by hand.

Kickback and related warnings

Kickback is the sudden reaction to a pinched
or snagged rotating application tool. Pinching
or snagging causes the rotating application
tool to rapidly stop. This can cause a power
tool to be forced in the opposite direction to
the rotating application tool at the point of
binding.
For example, if the indexable insert is snagged
or pinched in the workpiece, the edge of the
indexable insert entering into the workpiece
can get caught, causing the indexable insert to
break out or cause kickback. The indexable-
insert holder may either jump toward or
away from the operator, depending on the
direction of the indexable-insert holder at the
point of binding. Indexable inserts can also
break under these conditions.
Kickback is the result of power tool misuse or
incorrect operating procedures. It can be
avoided by taking proper precautions as
described below.
Maintain a firm grip on the power tool and
position your body and arms to allow you to
resist kickback forces. The operator can con-
trol torque reactions or kickback forces, if
proper precautions are taken.
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.
Always feed the application tool into the
material in the same direction as the cutting
edge is exiting from the material (which is the
same direction as the chips are thrown).
Guiding the power tool in the wrong direc-
tion causes the cutting edge of the application
tool to climb out of the workpiece and pull
the tool in the direction of this feed.
Do not jam or seize the indexable insert or
apply excessive pressure than the maximum
allowed. Do not set a larger bevel height than
maximally allowed. Overstressing the index-
able inserts increases the loading and suscep-
tibility to wedging or snagging in the cut, and
thus increases the possibility of kickback or
indexable insert breakage.
Do not position your body directly in front or
behind the indexable insert when operating
the machine, position yourself parallel to the
cutting surface. When moving the indexable
inserts into the workpiece any potential kick-
back could result in contact with the index-
able inserts.
Turn or replace blunt indexable inserts or
those with worn off coating in good time.
Blunt indexable inserts increase the risk of the
machine jamming and breaking out.
Do not use the power tool without the guide
plate.
Further safety warnings
Use ear protection during operation.
Indexable inserts, indexable-insert holder,
workpiece and chippings can be hot after
working. Wear protective gloves.
