• Check that the saw blade has no teeth missing and
shows no cracks or splits. Any such saw blades must
be replaced at once.
• The saw guard must not be set higher than is
necessary to allow the work to pass.
• The riving knife must be thinner than the kerf and
thicker than the body of the saw blade.
• Never exert lateral pressure on the saw blade or it
may break.
• Watch out for knots, nails, cuts and/or dirt deposits
in the wood, as they may cause dangerous kickback.
• Take care that no objects get into the dust extractor.
They could come into contact with the saw blade,
causing dangerous situations.
WHEN USING THE MACHINE
1. The work must be pressed firmly onto the
table top.
The cut-off part of the work must also be held so as
to prevent break-off. The hand used to hold the cut-
off must be behind the saw blade and move away
from it. In addition, the arm holding the work must
not be across the arm operating the machine.
2. Push the work slowly forward.
Do not feed the work too fast or the sawing machine
will be heavily loaded. The saw blade will then also be
subjected to excessive forces, which may result in
accidents.
3. Use a push stick.
Use a push stick when sawing small workpieces so as
to push the work past the saw blade.
4. Avoid using long extension cables.
Allow the machine to cool down when you intend to
move the sawing machine.
5. Wood remnants or the like that are in the
immediate vicinity of the rotating saw blade
must not be removed by hand.
When wood remnants are stuck between fixed
and/or moving parts, the machine must be stopped
and the plug taken out of the socket before they are
removed. Wood remnants must also be removed
from the dust extractor connector. These wood
remnants may come into contact with the saw blade,
which may give rise to dangerous situations.
6. The saw blade is one of the most important
components of a circular saw table.
Making the right choice of material, teeth and
number of revolutions and correctly sharpening and
fitting the saw blade not only prolong its life, but will
also prevent cracks or fractures and the dangers
arising from them. Only use the saw blades
recommended by the manufacturer.
7. When sawing short blocks a push stick must
be used that is about the same height as the
work.
The front of the push stick must be roughly V-shaped
and the push stick must be slightly raised in order to
prevent the wood from jumping up. The front of the
rip fence may not be more than 10 mm past the point
where the saw blade will cut into the wood over the
full height.
8. Sawing tenons or mortise work entails an
increased risk.
Tenons and mortise work should therefore be sawn
on a suitable machine (tenoning machine or milling
machine) and not on this saw bench.
9. Sawing waste wood and firewood must be
avoided.
Since the quality of the kerf is unimportant with these
types of wood, the user has a tendency not to
concentrate properly on the sawing operation, not
to check the work sufficiently for nails, knots and
other irregularities and to push hard against the saw.
When firewood is being sawn, there is a good chance
that the wood will roll, which could give rise to
dangerous situations. This is why it is recommended
that waste wood and firewood should not be sawn.
10.Large workpieces.
Large workpieces should be supported by a table
extension at the same height as the circular saw
table. Such an extension can be made of wood and
should be placed behind the machine and attached to
the workbench independently of the sawing
machine. You can also ask other trained people to
hold the wood. They must not however be young
people under the age of 18.
TURN OFF THE MACHINE IMMEDIATELY IN
THE EVENT OF:
•A defective mains plug or mains cord or damage to
the cord.
•A defective switch.
• Smoke or smell of scorched insulation.
EXAMPLES OF THINGS THAT CAN GO
WRONG IF CIRCULAR SAW TABLES ARE
USED INCORRECTLY!
1. Touching the rotating saw blade
This can happen if the protective devices and
accessories (such as the saw guard, screening
beneath the table top, the riving knife and the push
stick) are missing or incorrectly used. Incorrectly
functioning protective devices and accessories can
also cause accidents. When the machine is switched
off and is therefore no longer making a noise, the
user must exercise caution, as the saw blade may still
be rotating. The saw guard is also very important in
this situation.
2. Workpiece kickback
In the event of kickback of the work, people nearby
may be hit by the work flying off at great speed and
may suffer serious or even fatal injury. Kickback of
the workpiece may have the following causes,
possibly in combination with one another:
• The work sticking to the saw blade because there is no
riving knife or the riving knife used is too thin or
incorrectly set.
• There is no rip fence (straight edge) or it is incorrectly
set. The wood can then get stuck between the main
guide and the rotating saw blade.
3. The rotating saw blade breaks
This may be caused by:
• Incorrect sharpening method.
• Saw blade fitted incorrectly.
• Incorrect working procedure.
• Sawing material that is unsuitable for the saw blade.
