11.5 Remedy of faults
No defect should arise if you operate the machine properly and practise suitable
maintenance regularly. In case that the sawdust sticks onto saw blade or the exhausting
hose is filled up - switch off the electric motor before beginning of a repair, otherwise it could
get damaged. Switch off the electric motor immediately, if the machine is getting jammed
with the workpiece. The blunt saw blade is often a cause of the motor overheating. If the
machine embodies increased vibrations, check its placing, fixing, or fixing and balance of
tools.

piece more slowly.
