Operation
7.2 Blade selection and maintenance
The gap between the individual teeth should be large
enough to carry the material chips and to throw them
away. If the gap is too small, the blade will overheat and
rupture.
Do not use kinked, ruptured or bent saw blades.
For soft wood, the set should be a max. of twice the
thickness of the saw blade and for hard wood, a max. of
1.5 times the thickness of the saw blade.
Change blunt blades and have them sharpened by a
specialist workshop or purchase a new saw blade.
It is recommended to use only high quality saw blades.
The following saw blades may be used:

Attention! Once the machine is no longer in use, loosen the belt tension and place an appropriate
warning sign on the machine. This will thus prevent damage to the wearing surface of the wheels.
Selecting the type of saw blade and its width, depends on the material to be cut and the type of cut:
• Narrow saw blades are designed for curved and circular cuts, whereas wide saw blades are desi-
gned for straight cuts.
• A fine-toothed saw blade is required for hard wood, whereas a coarse-toothed saw blade is required
for soft wood.
