Additional Safety Rules For Mitre Saws - DeWalt DW743N QS Originalanweisungen

EN G LI S H
• Disconnect the machine from the mains supply before leaving the
working place.
• Do not use the saw without the guards and riving knife in position
and properly maintained, especially when changing from mitre saw
mode to bench saw mode, or vice versa.
• Make sure the floor area around the machine is level, well
maintained and free of loose materials, e.g. chips and cut-offs.
• Make sure adequate general or localized lighting is provided.
• Wear suitable personal protective equipment when necessary,
including:
– hearing protection to reduce the risk of induced hearing loss;
– respiratory protection to reduce the risk of inhalation of harmful
dust;
– gloves for handling saw blades and rough material. Saw blades
should be carried in a holder wherever practicable.
• Before making any operation ensure the machine is located on an
even and stable surface.
• Refrain from removing any cut-offs or other parts of the work piece
from the cutting area while the saw is running and the saw head is
not in the rest position.
• Replace the table insert when worn.
• Replace the table when the slot in the table is too wide.
• Report faults in the machine, including guards or saw blades, to
your dealer as soon as they are discovered.
• Ensure that the upper portion of the saw blade is completely
enclosed in the mitre sawing mode.
• Ensure that the arm is securely fixed in the working position in the
bench sawing mode.
• Ensure that the arm is securely fixed when bevelling in the bench
saw mode.
• Take care when grooving during the bench saw operation by using
appropriate guarding system. Slotting is not allowed.
• Connect the saw to a dust collection device when sawing wood.
Always consider factors which influence exposure of dust such as:
-– Type of material to be machined (chip board produces more
dust than wood);
-– Correct adjustment of the saw blade;
-– Ensure that the local extraction as well as hoods, baffles and
chutes are properly adjusted.
-– Dust extractor with air velocity not less than 20 m/s
• Do not use any abrasive discs or diamond cutting wheels..
• In case of an accident or machine failure, immediately turn the
machine off and disconnect machine from the power source.
• Report the failure and mark the machine in suitable form to prevent
other people from using the defective machine.
• When the saw blade is blocked due to abnormal feed force during
cutting, turn the machine off and disconnect it from power supply.
Remove the workpiece and ensure that the saw blade runs free.
Turn the machine on and start new cutting operation with reduced
feed force.
• Never cut light alloy, especially magnesium.
• Whenever the situation allows, mount the machine to a bench
using bolts with a diameter of 8 mm and 80 mm in length (fig. C2).

Additional Safety Rules for Mitre Saws

• Make sure all locking knobs and clamp handles are tight before
starting any operation.
• Do not operate the machine without the guard in position, or if the
guard does not function or is not maintained properly.
• Never use your saw without the kerf plate.
• Never place either hand in the blade area when the saw is
connected to the electrical power source.
• Never attempt to stop a machine in motion rapidly by jamming a
tool or other means against the blade; serious accidents can be
caused unintentionally in this way.
• Before using any accessory consult the instruction manual. The
improper use of an accessory can cause damage.

• Select the correct blade for the material to be cut.
• Use a holder or wear gloves when handling a saw blade or rough
material.
• Raise the blade from the kerf in the workpiece prior to releasing the
switch.
• Ensure that the arm is securely fixed when performing bevel cuts.
• Do not wedge anything against the fan to hold the motor shaft.
• The blade guard on your saw will automatically raise when the arm
is brought down; it will lower over the blade when the arm is raised.
The guard can be raised by hand when installing or removing saw
blades or for inspection of the saw. Never raise the blade guard
manually unless the saw is switched off.
• Keep the surrounding area of the machine well maintained and free
of loose materials, e.g. chips and cut-offs.
• Check periodically that the motor air slots are clean and free of
chips.
• Replace the kerf plate when worn.
• Disconnect the machine from the mains before carrying out any
maintenance work or when changing the blade.
• Never perform any cleaning or maintenance work when the
machine is still running and the head is not in the rest position.
• When possible, always mount the machine to a bench.
• If you use a laser to indicate the cutting line, make sure that the
laser is of class 2 according to EN 60825-1:2007. Do not replace
a laser diode with a different type. If damaged, have the laser
repaired by an authorised repair agent.
• Never use the machine in mitre saw mode as long as the guard is
not fitted (50, fig. D).
• Never cut workpiece shorter than 150 mm.
• Without additional support the machine is designed to accept the
maximum workpiece size of:
– Height 68 mm by width 140 mm by length 600 mm
– Longer workpieces need to be supported by suitable additional
table, e.g. DE3497. Always clamp the workpiece safely.
• Always clamp the workpiece safely.
Additional Safety Rules for Bench Saws
• Do not use saw blades with a body thickness greater or a width of
tooth smaller than the thickness of the riving knife.
• Make sure that the blade rotates in the correct direction and that
the teeth are pointing to the front of the bench saw.
• Be sure all clamp handles are tight before starting any operation.
• Be sure all blade and flanges are clean and the recessed sides of
the collar are against the blade. Tighten the arbor nut securely.
• Keep the saw blade sharp and properly set.
• Make sure that the riving knife is adjusted to the correct distance
from the blade - maximum 5 mm.
• Never operate the saw without the upper and lower guards in
place.
• Keep your hands out of the path of the saw blade.
• Disconnect the saw from the mains supply before changing blades
or carrying out maintenance.
• Use a push stick at all times, and ensure that you do not place
hands closer than 150 mm from the saw blade while cutting.
• Do not attempt to operate on anything but the designated voltage.
• Do not apply lubricants to the blade when it is running.
• Do not reach around behind the saw blade.
• Always keep the push stick in its place when not in use.
• Do not stand on top of the unit.
• During transportation make sure that the upper part of the saw
blade is covered, e.g., by the guard.
• Do not use the guard for handling or transportation.
• Do not use blades with a body thickness greater or a width of tooth
smaller than the thickness of the riving knife.
• Consider applying specially designed noise-reduction blades.
