DeWalt D27105 Instruction Manual page 17

• 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 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.
• Rebating, slotting or grooving is not allowed.
• Ensure riving knife is adjusted correctly. Never cut without riving knife
assembled.
Never cut work-piece 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
• 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 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 HSS 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 stillstand 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.
• 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 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 prevents
other persons from use 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.
• A laser to indicate the cutting line is supplied with the D27107V, the
laser is of class 2 according to EN 60825-1. Do not replace a laser
diode with a different type. If damaged, have the laser repaired by an
authorised repair 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.
- Risk of injury when changing the blade.
- Risk of squeezing fi ngers when opening the guards.
- Health hazards caused by breathing dust developed when sawing
wood, especially oak, beech and MDF.
The following factors are of infl uence to noise production:
• The material to be cut
• The type of saw blade
• The feed force
The following factors increase the risk of breathing problems:
• No dust extractor connected when sawing wood
• Insuffi cient dust extraction caused by uncleaned exhaust fi lters
• Worn saw blade
• Workpiece not exactly guided
