4.1 Replacing conveyor belt
If significant looseness, contamination, or scuffing is found in the conveyor belt when performing the work
steps stated in "5.2 Inspecting conveyor belt and cleaning guide" in chapter 3, the conveyor belt needs to be
replaced. Follow the steps below to replace the conveyor belt.
YSM20R/YSM20WR has following 4 types of conveyor.
• YSM20R Dual-stage type
• YSM20R Single-lane type
• YSM20WR Dual-lane type
• YSM20WR Single-lane type (for transferring heavy board)
Regarding YSM20R/YSM20WR Single-lane type / YSM20WR Dual-lane type machines, the procedures for
replacing the conveyor belt are mostly the same. However W2-axis and W3-axis of YSM20R Dual-stage type
machine partly differ the replacing procedure.
1
Change the conveyor width to a
convenient width for maintenance
work.
1. Press the [Width] button to display the
"Conveyor Width" screen.
2. In the "Target Width" box, enter a width
wide enough (about 200 mm) for using
tool (hex wrench) and press [OK] button.
The conveyor is changed to the specified
width
2
Make the preparation for cleaning.
e
1. Take off all accessories susceptible to the
magnetic fields, such as a wristwatch
and/or magnetic ID card.
2. Press the emergency stop button and
then open the machine safety cover
3. If the machine is the carriage type,
detach the carriage to easily access to
the conveyor.
4. Place a square cloth on the push-up
plate.
3
Detach the board clamp plates.
Use a hexagon wrench (3) to remove the 4
board clamp bolts, then detach the board
clamp plate.
c
CAUTION
Do not remove any bolts other than the 4 bolts shown in
the figure at right.

Loosen the belt.
1. Before loosening the conveyor belt, mark the current position of pulley bracket (YSM20R/YSM20WR
Single-lane type/YSM20WR Dual-lane type: pulley mounting bolt) with a permanent marker.
2. See the figure below and loosen 2 bolts mounting pulley bracket with hex wrench (3) and move the
bracket to the end of the slotted hole (in loosening direction).
YSM20R/YSM20WR Single-lane type/YSM20WR Dual-lane type: Loosen pulley mounting bolts with hex
wrenches (4 and 5) and move the pulley.

* This image is right flow type.
Regarding YSM20WR Single-lane, the tensioner (pulley) locates at the downstream side of the flow direction.

Tip
Regarding YSM20W Single-lane, the tensioner (pulley) locates at the downstream side of the conveyor flow direction.
Therefore the tensioner (pulley) location varies if the machine flow direction is different.
