Working Advice

General Sawing Instructions
For all cuts, it must first be ensured that the
saw blade at no time can come in contact
with the fence, screw clamps or other ma-
chine parts. Remove possibly mounted aux-
iliary stops or adjust them accordingly.
Protect the saw blade against impact and shock.
Do not subject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The work-
piece must always have a straight edge to face
against the fence.
Long workpieces must be underlaid or support-
ed at their free end.
