2. Replacing conveyor belt
The conveyor belt should be replaced if excessive slack, grime or fraying is found after checking it as
described in "5.3.1 Inspecting conveyor belt and cleaning guide and pulley" in Chapter 3. Use the
following procedure to replace the belt.
2.1 Replacing the conveyor belt
1
Prepare for work.
e
1. Remove all items sensitive to magnetic
fields such as wristwatches and magnetic
ID cards.
2. Press the emergency stop button and
then open the machine safety cover.
3. Use the CLAMP ON/OFF switch to lower
the feeder exchange carriage and
detach it.
4. Detach the tape cutter duct.
5. Place a square cloth on the push-up
plate.
2
Detach the board clamp assembly.
Use a hex wrench (2.5) to remove the bolts (4
places shown in the figure at right) that
mount the board clamp assembly.

c
CAUTION
Do not remove any bolts other than the 4 bolts shown in
the figure at right.
3
Put a mark at the pulley position.
Using an oil-based pen, put a mark to
indicate the position of the bolt that mounts
the tensioner pulley.

4
Loosen the belt.
1. Use two hex wrenches to loosen the belt
tensioner pulley and move it to the end
of the tension adjusting slot (in the
loosening direction).
Hex wrench on pulley side : 5 mm
Hex wrench on bolt side : 4 mm
2. Use a slotted screwdriver to detach the
end pulley shaft next to the tensioner
pulley just loosened and then detach the
end pulley.

Separate the belt drive pulley from
the shaft.
1. Use a hex wrench (2.5) to loosen the
bolts on the coupling.
2. Disconnect the coupling from the drive
pulley to allow a gap through which the
belt can be taken out.

Detach the belt from the conveyor.
Detach the conveyor belt by taking it out
through the gap between the coupling and
the drive pulley.

Clean the guides and pulleys.
1. Use a vacuum assembly (option) to
suction the belt wear debris on the belt
guides and sensors, etc.
2. Use a plastic spatula or similar tool to
remove the belt wear debris adhering to
the outer peripheral surface of the
pulleys.
3. Use a brush or similar tool to remove the
belt wear debris caught in the belt
guides.

CAUTION
Do not use a solvent (IPA, etc.) unless the guides and
pulleys are excessively dirty. If using a solvent, be
careful not to spill the solvent on the bearing in the
pulleys during cleaning.
