Residual Risks - DeWalt DWS779 Bedienungsanleitung

EnGLISh
• Use a holder or wear gloves when handling a saw blade or rough material.
• Ensure that the saw blade is mounted correctly before use.
• Make sure that the blade rotates in the correct direction.
• Do not use blades of larger or smaller diameter than recommended. For
the proper blade rating refer to the technical data. Use only the blades
specified in this manual, complying with EN 847-1.
• Do consider applying specially designed noise-reduction blades.
• Do not use HIGH SPEED STEEL blades.
• Do not use cracked or damaged saw blades.
• Do not use any abrasive or diamond discs.
• Never use your saw without the kerf plate.
• Before each cut ensure that the machine is stable.
• Raise the blade from the kerf in the workpiece prior to releasing the switch.
• Do not wedge anything against the fan to hold the motor shaft.
• The blade guard on your saw will automatically raise when the head
up-lock release lever is pushed and the arm is brought down; it will lower
over the blade as the arm is raised.
• Never raise the blade guard manually unless the saw is switched off. The
guard can be raised by hand when installing or removing saw blades or
for inspection of the saw.
• Check periodically that the motor air slots are clean and free of chips.
• Replace the kerf plate when worn. Refer to service parts list included.
• 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 upper position.
• If you use an LED to indicate the cutting line, make sure that the LED
is of class 2 according to EN 62471. Do not replace an LED diode with
a different type. If damaged, have the LED repaired by an authorised
repair agent.
• The front section of the guard is louvered for visibility while cutting.
Although the louvers dramatically reduce flying debris, they are openings
in the guard and safety glasses should be worn at all times when viewing
through the louvers.
• Connect the saw to a dust collection device when sawing wood. Always
consider factors which influence exposure of dust such as:
ʵ type of material to be machined (chip board produces more dust than
wood);
ʵ sharpness of the saw blade;
ʵ correct adjustment of the saw blade;
ʵ dust extractor with air velocity not less than 20m/s.
• Ensure that the local extraction as well as hoods, baffles and chutes are
properly adjusted.
• Please be aware of the following factors influencing exposure
to noise:
ʵ use saw blades designed to reduce the emitted noise;
ʵ use only well sharpened saw blades.
• Machine maintenance shall be conducted periodically.
• Provide adequate general or localized lighting.
• Ensure that any spacers and spindle rings are suitable for the purpose as
stated in this manual.
• 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 upper position.
• Never cut workpieces shorter than 200 mm.
• Without additional support the machine is designed to accept the
maximum workpiece size for cross-cutting:
ʵ Maximum height: 112 mm
ʵ Maximum width: 345 mm
ʵ Maximum length: 600 mm
34
ʵ Longer workpiece needs to be supported by suitable additional
support, e.g. DE7023-XJ or DE7033-XJ legstand. Always clamp the
workpiece safely.
• 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.
• Ensure the operator is adequately trained in the use, adjustment and
operation of the machine.
• Before working select the correct saw blade for the material to be cut.
• Use only saw blades where the speed marked on the saw blade is at least
equal to the speed marked on the rating blade.
• Ensure before each cut that the machine is located on an even and stable
surface to prevent movement.

WARNING: We recommend the use of a residual current device with a
residual current rating of 30mA or less.

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.
• Risk of injury when changing the blade.
• Risk of squeezing fingers when opening the guards.
• Health hazards caused by breathing dust developed when sawing wood,
especially oak, beech and MDF.
The following factors increase the risk of breathing problems:
• No dust extractor connected when sawing wood.
• Insufficient dust extraction caused by uncleaned exhaust filters.
Markings on Tool
