7.7 Replacing the Saw Blade
WARNING
Before exchanging the saw blade, pull
the mains plug from the power sup ply
socket.
Wear protective gloves!
The sawing performance and the quality of the
cut depend essentially on the condition and
tooth form of the saw blade. Therefore, use
only sharp saw blades that are suitable for the
material to be worked.
Swing back the swinging guard with the lever
[3-5].
Install a suitable saw blade according to the
illustration and tighten. Take care that the
mounting flange [3-4] and the clamping flange
[3-2] are correctly positioned. The holes in the
saw blade [3-3] must fi t onto the follow-up
pins on the mounting fl ange [3-4].
WARNING
Observe for installation: The cutting di-
rection of the teeth (arrow on the saw
blade) must match the direction of the
arrow on the guard.
Check the function of the swinging
guard.
Tighten the hexagon bolt [3-1] using the SW19
Allen key supplied, while holding the clamping
fl ange [3-2] with the single ring spanner which
is also supplied.
To remove the blade, follow the same sequence
in reverse.
8 Operating Instructions
►
Do not cut into nails, screws, etc.
►
Do not work with materials containing as-
bestos.
►
Do not use saw blades that have cracks or
that are damaged.
►
Under no circumstances use abrasive
disks!
►
Saw blades of highly alloyed, high-speed
steel (HSS-steel) must not be used.
►
Feeding too fast significantly reduces the
performance of the machine and short ens
the life of the saw blade.
22
►
Use only sharp saw blades in perfect con-
dition.
►
Uncoated saw blades can be protected from
corrosion with a thin coat of acid free oil.
►
Resin and glue on the saw blade cause poor
cutting results. Therefore, clean the saw
blade immediately after use.
8.1 Working different materials
Wood
The proper selection of the saw blade is de-
pendent on the type and quality of the wood
as well as whether the wood is to be sawed
along or across the grain. Beech and oak dust
is especially detrimental to health and there-
fore should be worked only with vacuum dust
extraction.
Plastic
When cutting plastic, especially PVC, long, spi-
ral shaped shavings are produced that can be
electrostatically charged.
This can cause the ejector to become clogged
and the swinging protective guard [1-8] to
stick. The use of a vacuum cleaner for dust
extraction is recommended.
Apply the machine running against the work-
piece and carefully start sawing. Then saw
steadily and without interruption so that the
saw teeth have less chance of sticking.
Non-ferrous Metals
Use only a suitable and sharp saw blade. This
ensures a clean cut and prevents jam ming of
the saw blade.
Apply the machine running to the workpiece,
carefully start sawing and then saw with slow
feeding and without interruption.
For profiles, always start the cut on the small
side; for U-profiles, never start the cuts on the
open side.
Support long profile, otherwise the saw blade
can become jammed when the profile tips over
and the machine can "kick back".
Material with Mineral Content (Light
building material)
►
Only dry cutting is permitted.
►
Use vacuum dust extraction. The vacu um
cleaner must be suitable for masonry dust.
