the overload cutout to reset.
Check that motor air intakes are clear.
Perform the cut on the piece at the correct pressure.
Specialized personnel should check the machine; do
not attempt to repair the machine by yourself.
Set the retainers by unloosening the fastening screws
and re-positioning them.
Decrease cutting pressure.
Check the cutting parameters (blade toothing, cutting
speed) in the cuts table (point 4.7).
Check blade-guide adjustment (points 3.5 and 3.6).
Check piece positioning and clamping in the vice
(point 4.5).
Check the cutting parameters (blade toothing, cutting
speed) in the cuts table (point 4.7).
Decrease cutting pressure.
Check eccentric blade-guide adjustment (point 3.6).
Specialized personnel should check the pulleys and
replace them if necessary.
Never use any type of lubricant or coolant for the
