• Never use your saw without the kerf plate.
• Raise the blade from the kerf in the workpiece prior to releasing the
switch.
• Before each cut ensure that the machine is stable.
• 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 head lock up
release lever (b) is pushed.
• 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.
• 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 fitted with laser, no exchange with different type of
laser permitted. Repairs shall only be carried out by the laser
manufacturer or an authorized 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.
• Please be aware of the following factors influencing exposure
to noise:
-– use saw blades designed to reduce the emitted noise;
-– use only well sharpened saw blades;
• Machine maintenance shall be conducted periodically;
• Provide adequate general or localized lighting;
• Ensure the operator is adequately trained in the use, adjustment
and operation of the machine;
• 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 rest position
• Never cut workpieces shorter than 150 mm.
• Without additional support the machine is designed to accept the
maximum workpiece size of:
– Height 60 mm by width 270 mm by length 500 mm
– Longer workpieces need to be supported by suitable additional
table, e.g. DE7023. 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.
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 unprotected saw 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 increases the risk of breathing problems:
– No dust extractor connected when sawing wood
– Insufficient dust extraction caused by uncleaned exhaust filters
