Residual Risks - DeWalt D27107 Original Instructions Manual

Additional safety rules for saw benches
• Make sure that the blade rotates in the correct direction and the teeth
are pointing to the front of the saw bench.
• Make sure all locking knobs and 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.
• Use correctly sharpened saw blades. Observe the maximum speed
mark on the saw blade. The marked maximum speed shall always be
higher than the speed marked on rating plate.
• Never operate the saw without the upper and lower guards in place.
• Never place either hand in the blade area when the saw is connected to
the electrical power source.
• Disconnect the saw from the mains before changing blades or carrying
out maintenance.
• Use a push stick at all times, and ensure that you do not place hands
closer than 200 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.
• Rebating, slotting or grooving is not allowed.
• Ensure riving knife is adjusted correctly. Never cut without riving knife
assembled.
• Never cut workpiece smaller than 30 mm.
• Without additional support the machine is designed to accept the
maximum workpiece size of:
– Height 81 mm by width 400 mm by length 600 mm
– Longer workpieces need to be supported by suitable additional
table, e.g. D271055 or D271058.
Additional safety rules for fl ip-over saws
• Before using the saw ensure that the machine is stable. Never position
the machine on uneven ground. If needed secure the machine to a
workbench using 150 mm long hexagon head bolts.
• Never operate the machine without the guards in position, especially
after a mode change. Keep the guards in good working order and
properly maintained.
• Replace table insert when worn.
• 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.
• Ensure the table is correctly locked when changing the saw mode.
• Never saw ferrous or non-ferrous materials when ripping in the bench
saw mode.
• Before using any accessory consult the instruction manual. The
improper use of an accessory can cause damage.
• Observe the maximum speed marked on the saw blade.
• Use a holder or wear gloves when handling a saw blade.
• Ensure that the blade rotates in the correct direction. Keep the blade
sharp.
• The max. allowable speed of the saw blade must always be equal to or
greater than the no-load speed of the tool specified on the nameplate.
• Do not use saw blades that do not conform to the dimensions stated
in the technical data. Do not use any spacers and spindle rings to
make a blade fit onto the spindle. Use only the blades specified in this
manual, complying with EN 847-1.
• Consider applying specially designed noise-reduction blades.
• Do not use HIGH SPEED STEEL blades.
• Do not use cracked or damaged saw blades.
• After completing the cut, release the switch and wait for the saw blade
to come to a complete stop before returning the head to its upper rest
position.
• 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.
• Disconnect the machine from the mains before carrying out any
maintenance work or when changing the blade.
• Use only saw blades specified by the manufacturer. Ensure that the
riving knife is not thicker than the width of the groove cut by the saw
blade and not thinner than the body of the saw blade.
• Make sure the machine is placed on an even surface with sufficient
stability.
• Do not use abrasive or diamond disc.
• In case of an accident or machine failure immediately switch the
machine off and disconnect from 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.
• Refrain from removing any cut-offs or other parts of the workpiece from
the cutting area while the machine is running and the saw head is not in
the rest position
• Do not use the machine without the legs mounted.
• Make sure your position is always left or right of the cutting line.
• Provide adequate general or localized lighting.
• Ensure the operator is adequately trained in the use, adjustment and
operation of the machine.
• Switch the machine off when unattended.
• Make sure that the LED meets EN 62471. Do not replace the LED
with a different type. If damaged, have the LED light repaired by an
authorized service agent.
• 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);
-– sharpness of the saw blade;
-– correct adjustment of the saw blade,
-– dust extractor with air velocity not less than 20 m/s.
Ensure that the local extraction as well as hoods, baffles and chutes are
properly adjusted.
• Never cut light alloy, especially magnesium.

Residual risks

The following risks are inherent to the use of saws:
- injuries caused by touching the rotating parts.
In spite of the application of the relevant safety regulations and the
implementation of safety devices, certain residual risks cannot be avoided.
These are:
- Impairment of hearing;
- Risk of accidents caused by the uncovered parts of the rotating saw
blade;
