PROBLEMS CAUSES

Defective motor, power cable or
plug.
Blown electric panel fuses.
No voltage in the mains system.
The overload cutout has tripped.
Motor overheating.
M o t o r o v e r l o a d c a u s e d b y
excessive cutting pressure.
Motor breakdown.
The setting of the H and K retainers
(point 3.3) is inaccurate.
Excessive cutting pressure (on
pipes and section bars).
Incorrect blade toothing in relation
to the piece to cut.
Incorrect adjustment of the eccentric
and sliding blade-guides.
Incorrect cutting speed in relation
to the piece to cut.
The piece is wrongly positioned
in the vice.
The blade is worn or its toothing
is not right for the thickness of the
piece being cut.
Excessive cutting pressure.
Incorrect eccentric blade-guide
adjustment.
Excessive wear of the pulley rubber
linings.
The blade slips on the pulleys,
caused by oil or grease required
for cutting operations.
SOLUTIONS SUGGESTED
Specialized personnel should check the machine; do
not attempt to repair the motor by yourself.
Check fuse integrity and replace, if necessary.
Check for voltage in the mains system.
Release the run button and wait a few minutes for 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 4.6).
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 4.6).
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
cutting operations; specialized personnel should check
and, if necessary, replace the pulleys.
