3
Remove the conveyor belt.
Remove the conveyor belt from the pulley
and the belt groove of the board guide.
4
Check for wear on the board
conveying side of the conveyor belt.
After removing the belt in step 3, check for
wear on the board conveying side of that
conveyor belt.
TIP
About half (3 to 4 mm) the belt width is used for board
conveying. If the board conveying side of the conveyor
belt is worn, then you can still reuse the belt by switching
the used side with the opposite side. However, this will
cause errors after long-term use, so early belt
replacement is recommended.
5
Clean the pulley and the belt
groove on the board guide.
Using a vacuum cleaner or similar device,
suction up the belt wear dust deposited in
the belt groove or on the sensor surface. Also
use a vacuum cleaner while brushing debris
away with the brush supplied with the
machine.
Also clean the pulley and other parts for the
conveyor belt.
