MUTOH SC-550 Maintenance Manual page 57

Step 7 : Move the head to the right end of the Y-rail and measure with a bar tension gauge (range : 500g,
MUTOH Part# JD-41446B) the tension of the belt in the middle of the Y-rail (Please refer to
picture mentioned below).
Push the belt with the bar tension gauge (with steel belt tension attachment MUTOH part# JD-
41565) to touch the rail and release gently the pressure on the gauge.
The movement that the belt starts to release from the rail is the moment of reading the value on
the bar tension gauge.
The values are different for each size machine :
SC-550
205 ± 5 g
The tension can be adjusted by turning the screws on the return pulley CW for more tension and
CCW for less tension.
Caution :
Pay attention to the tension on the belt during this alignment.
The tension should stay between acceptable values (Please refer to step 7).
SC-650
205 ± 5 g
Caution :
While adjusting the tension, keep on checking the track of the belt on the
return pulley (Please refer to step 5).
