c) The workpiece must be stationary and
clamped or held against both the fence and
the table. Do not feed the workpiece into the
blade or cut "freehand" in any way.
Unrestrained or moving workpieces could be
thrown at high speeds, causing injury.
d) Push the saw through the workpiece. Do
not pull the saw through the workpiece. To
make a cut, raise the saw head and pull it out
over the workpiece without cutting, start the
motor, press the saw head down and push
the saw through the workpiece. Cutting on the
pull stroke is likely to cause the saw blade to
climb on top of the workpiece and violently throw
the blade assembly towards the operator.
e) Never cross your hand over the intended
line of cutting either in front or behind the
saw blade. Supporting the workpiece "cross
handed" i.e. holding the workpiece to the right of
the saw blade with your left hand or vice versa is
very dangerous.
f) Never reach behind the fence when the saw
blade is rotating. with either hand closer than
100 mm from either side of the saw blade, to
remove wood scraps, or for any other reason
while the blade is spinning. The proximity of
the spinning saw blade to your hand may not be
obvious and you may be seriously injured.
g) Inspect your workpiece before cutting. If
the workpiece is bowed or warped, clamp it
with the outside bowed face toward the
fence. Always make certain that there is no
gap between the workpiece, fence and table
along the line of the cut. Bent or warped
workpieces can twist or shift and may cause
binding on the spinning saw blade while cutting.
There should be no nails or foreign objects in the
workpiece.
h) Do not use the saw until the table is clear
of all tools, wood scraps, etc. except for the
workpiece. Small debris or loose pieces of wood
or other objects that contact the revolving blade
can be thrown with high speed.
i) Cut only one workpiece at a time. Stacked
multiple workpieces cannot be adequately
clamped or braced and may bind on the blade or
shift during cutting.
j) Ensure the mitre saw is mounted or placed
on a level, firm work surface before use. A
level and firm work surface reduces the risk of the
mitre saw becoming unstable.
k) Plan your work. Every time you change the
bevel or mitre angle setting, make sure the
adjustable fence is set correctly to support
the workpiece and will not interfere with the
blade or the guarding system. Without turning
the tool "ON" and with no workpiece on the table,
move the saw blade through a complete
simulated cut to assure there will be no
interference or danger of cutting the fence.
l) Provide adequate support such as table
extensions, saw horses, etc. for a workpiece
that is wider or longer than the table top.
Workpieces longer or wider than the mitre saw
table can tip if not securely supported. If the cut-
off piece or workpiece tips, it can lift the lower
guard or be thrown by the spinning blade.
m) Do not use another person as a substitute
for a table extension or as additional support.
Unstable support for the workpiece can cause the
blade to bind or the workpiece to shift during the
cutting operation pulling you and the helper into
the spinning blade.
n) The cut-off piece must not be jammed or
pressed by any means against the spinning
saw blade. If confined, i.e. using length stops,
the cut-off piece could get wedged against the
blade and thrown violently.
o) Always use a clamp or a fixture designed
to properly support round material such as
rods or tubing. Rods have a tendency to roll
while being cut, causing the blade to "bite" and
pull the work with your hand into the blade.
p) Let the blade reach full speed before
contacting the workpiece. This will reduce the
risk of the workpiece being thrown.
q) If the workpiece or blade becomes
jammed, turn the mitre saw off. Wait for all
moving parts to stop and disconnect the plug
from the power source. Then work to free the
jammed material. Continued sawing with a
jammed workpiece could cause loss of control or
damage to the mitre saw.

r) After finishing the cut, release the switch,
hold the saw head down and wait for the
blade to stop before removing the cut-off
piece. Reaching with your hand near the coasting
blade is dangerous.
s) Hold the handle firmly when making an
incomplete cut or when releasing the switch
before the saw head is completely in the
down position. The braking action of the saw
may cause the saw head to be suddenly pulled
downward, causing a risk of injury.

4.1 Additional Safety Instructions

· Please also observe the special safety
instructions in the respective chapters.
· Where applicable, follow the legal directives or
regulations for the prevention of accidents.
General hazards!
· Consider environmental conditions:
· When working long stock use suitable supports.
· The saw shall only be started and operated by
persons familiar with circular saws and who are
at any time aware of the dangers associated
with the operation of such tools.
Persons under 18 years of age shall use this
machine only in the course of their vocational
training, under the supervision of an instructor.
· Keep bystanders, particularly children, out of
the danger zone. Do not permit other persons to
touch the machine or power cable while it is
running.
· Avoid overheating of the saw teeth.
· When sawing plastic, avoid melting of the
plastic.
Risks of personal injury and crushing
by moving parts!
· Do not operate the machine without installed
guards.
· Always keep sufficient distance to the saw
blade. Use suitable feeding aids, if necessary.
Keep sufficient distance to driven components
when operating this machine.
· Wait for the saw blade to come to a complete
stop before removing cutoffs, scrap, etc. from
the work area.
· Cut only stock of dimensions that can be safely
held during cutting.
· Use clamping devices or a vice to hold the
workpiece. It is held safer by these devices than
by your hand.
· Do not attempt to stop the saw blade by pushing
the workpiece against its side.
· Disconnect the mains plug before starting any
setting, maintenance or repair work.
· Disconnect the mains plug if the tool is not used.
Cutting hazard, even with the cutting
tool at standstill!
· Wear gloves when changing cutting tools.
· Store saw blade in such manner that nobody will
get hurt.
Danger from kickback of the saw head
(saw blade gets caught in the workpiece and
the saw head suddenly kicks back)!
· Select a saw blade suited for the material to be
cut.
· Keep the handle tight. When the saw blade
enters the workpiece, the risk of kickback is
particularly high.
· Cut thin or thin-walled workpieces only with fine-
toothed saw blades.
· Always use sharp saw blades. Replace
damaged saw blades immediately. There is an
increased risk of kickback if a blunt sawtooth
gets caught in the workpiece's surface.
· Do not jam any work pieces.
· If in doubt, check work piece for inclusion of
foreign matter (e.g. nails or screws).
· Never cut several work pieces at the same time
– and also no bundles containing several
individual pieces. Risk of personal injury if
individual pieces are caught by the saw blade
uncontrolled.
· When making grooves avoid lateral pressure on
the saw blade - use a clamping device.
Entanglement hazard!
· Ensure that during operation no parts of the
body or clothing can be caught and drawn in by
rotating components (no ties no gloves, no
clothes with wide sleeves; contain long hair with
a hairnet).
· Never cut workpieces to which ropes, cords,
strings, cables or wires are attached or which
contain such materials.
Hazard generated by insufficient
personal protection gear!
· Wear hearing protection.
· Wear safety glasses.
· Wear dust mask.
· Wear suitable work clothes.
· Wear non-slip footwear.
· Wear gloves when handling saw blades and
rough tools. Carry saw blades in a container.
Risk of injury by inhaled wood dust!
· Work only with a suitable dust collector attached
to the saw. The dust extraction unit must comply
with the values stated in chapter 15..
Reducing Dust Exposure:
· Some of the dust created using this power tool
may contain chemicals known to cause cancer,
allergic reactions, respiratory disease, birth
defects or other reproductive harm. Some
examples of such substances are, lead (in paint
containing lead), additives used for wood
treatment (chromate, wood preservatives),
some wood types (such as oak or beech dust).
· The risk from exposure to such substances will
depend on how long the user or nearby persons
are being exposed.
· Do not let particles enter the body.
· To reduce exposure to these substances: work
in a well ventilated area and wear protective
equipment, such as dust masks that are
specially designed to filter out microscopic
particles.
· Observe the relevant guidelines for your
material, staff, application and place of
application (e.g. occupational health and safety
regulations, disposal).
· Collect the generated particles at the source,
avoid deposits in the surrounding area.
· Use a suitable extraction unit. In this way, fewer
particles enter the environment in an
uncontrolled manner.
· Reduce dust exposure with the following
measures:
– do not direct the escaping particles and the
exhaust air stream towards yourself or nearby
persons or towards dust deposits,
– use an extraction unit and/or air purifiers,
– ensure good ventilation of the workplace and
keep it clean using a vacuum cleaner.
Sweeping or blowing stirs up dust.
– Vacuum or wash protective clothing. Do not
blow, beat or brush protective gear.
Hazard generated by modification of
the machine or use of parts not tested and
approved by the equipment manufacturer
· Assemble the machine in strict accordance with
these instructions.
· Use only parts approved by the manufacturer.
This applies especially to:
– Saw blades (for order numbers, refer to
chapter 11. "Accessories").
– Safety devices.
– Cutting laser.
