[VP-300]
Measure the tension of the belt at the
empty screw hole of the LM Guide between
the 2nd and 3rd Grit Rollers from the left
using Tension Gauge (ST-001)(*1).
Pull up the belt until its inside comes to
the top surface of the Cable Guide when
you see it from the machine front(*2). The
tension is proper if the measured value is
1.25kgf to 1.40kgf.
If the tension is improper, move on to the
next step and adjust the belt tension.
Loosen the 2 Fixing Screws which is located on the left
4
end of the belt halfway round.
Be careful with the sharp edges around the
belt when loosening the screws. It may cause
injury.
Insert a wrench through the holes on the Side Frame and
5
loosen the 2 screws to make a gap of 3mm between the
tip of the screw and Idle Pulley Holder.
(The belt tension cannot be adjusted higher when the screw
contacts with Idle Pulley Holder.)
The gap between the screws and Idle Pulley
can be seen from both front side and rear side
of the machine.
