Differences in conveyor belt replacement depending on the machine stage type
Regarding W2 and W3 conveyor belts for YSM20R Dual-stage type, belt replacement procedure is different from other
conveyor belts. Go on to Step 10 for replacement procedures other than W2/W3 conveyor belts for YSM20R Dual-stage type.

Read desired board data.
1. Read desired board data.
2. If the value on "B. Board Size Y (mm) on
"Board" screen is 380 mm or more, enter
the value less than 380 mm.

Move the conveyor U-axis.
1. Close the machine safety cover and
cancel the emergency stop. Set the

3. Press the emergency stop button and
then open the machine safety cover.
4. Detach the carriage if the machine is the
carriage type.
5. Moving the U-axis belt manually moves
the entire conveyor. For the W2-axis, fully
move the conveyor to the rear side by
moving the U-axis belt in the direction
indicated by an arrow shown in the
figure on the right. For the W3-axis, fully
move the conveyor to the front in the
same manner.
TIP
The stage 2 (W2-axis) and stage 3 (W3-axis) move back
and forth by pressing [Mount Position] button when
"Board Size Y" is less than 380 mm.

Separate the shaft.
Remove the bolt from the shaft (for the
pulley position, see the figure shown in Step
4) with a hex wrench (3).
