For example, if an indexable insert is snagged or
pinched by the workpiece, the edge of the insert that
is entering into the pinch point can dig into the
surface of the material causing the insert to climb
out or kick out. The indexable insert may either jump
towards or away from the operator depending on
direction of the indexable insert holder at the point
of pinching. Indexable inserts may also break under
these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating 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. The operator can control
kickback forces if proper precautions are taken.
b) Use special care when working in corners,
on 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.
c) Always feed the accessory 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). Feeding the
power tool in the wrong direction causes the cutting
edge of the accessory to move out of the workpiece
and pull the tool in the direction of this feed.
d) Prevent any jamming of the indexing insert
or excessive pressure. Do not set the chamfer
height greater than the permitted maximum.
Overstressing the indexable insert increases the
loading and susceptibility to twisting or binding of
the disc in the cut and the possibility of kickback or
breakage of the indexable insert.
e) Do not position your hand in line with and
behind the indexable insert. When the indexable
insert is moving away from your body at the point of
operation, the possible kickback may propel the
rotating indexable insert and the power tool directly
at you.
f) Turn/replace blunt indexable inserts or
inserts where the coating is worn in due time.
Blunt indexable inserts increase the risk of the
machine getting jammed and breaking.
4.2 Additional Safety Instructions:
Hold the power tool by the insulated gripping
surfaces because the milling cutter may hit its
own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power
tool "live" and could give the operator an electric
shock.
Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
WARNING – Always wear protective
goggles.
Wear ear protectors.
Pull the plug out of the socket before making
any adjustments, changing tools, carrying
out maintenance or cleaning.
Wear suitable work clothes.
Ensure that nobody gets injured by
catapulted foreign bodies.
Keep persons nearby and pets at a safe
distance to the device.
Keep away hair, loose clothing, fingers and
other body parts. They can get caught and
sucked in. Use a hair net for long hair.
Warning of rotating tools
Always wear protective goggles, gloves and sturdy
shoes when working with this tool.
Danger of injury from sharp edges. Wear protective
gloves.
Indexable inserts, holders for indexable inserts, the
workpiece and chips can be hot after work. Wear
protective gloves.
A damaged or cracked additional handle must be
replaced. Never operate the machine with a
defective side handle.
Pull the plug out of the socket before making any
adjustments, changing tools, carrying out
maintenance or cleaning.
Use of a fixed extractor system is recommended.
Always install an RCD with a maximum trip current
of 30 mA upstream. When the machine is shut down
by the RCD, it must be checked and cleaned. See
chapter 10. Cleaning.
Wear ear protectors when working for long
periods of time. High noise levels over a
prolonged period of time may affect your hearing.
Use only sharp, undamaged indexable blades.
The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must
be sufficiently supported.
Ensure that sparks produced during work do not
constitute a risk to the user or others and are not
able to ignite flammable substances. Areas at risk
must be protected with flame-resistant covers.
Always keep a fire extinguisher on hand when
working in areas prone to fire risk.
Always hold the machine with both hands on the
designated handles, take a secure stance and
concentrate on the work.
Keep your hands away from the milling area and
from the tool.
Do not touch the rotating accessory! Remove chips
and similar material only with the machine at a
standstill. Pull the mains plug out of the socket.
Damaged, eccentric or vibrating tools must not be
used.
Do not work overhead.
