Inspection and maintenance
3.5 Replacing the conveyor belt
The following describes how to replace the conveyor belt.
n
Required tools
• Hex wrench (3mm, 5mm)
• Fine brush
• Cleaning rag
• Replacement conveyor belt (KKX-M9124-00X BELT CONVEYOR)
e
1
Press the emergency stop button.
The machine must be in emergency stop to
ensure safety during work.
2
Slacken the belt.
Loosen the belt tensioner bolt with the hex
wrench (5mm) and slide the bolt fully along
the elongate hole (in the direction of
slackening the belt).

3
Detach the belt.
1. Use the hex wrench (3mm) to loosen the
mounting bolt securing the belt drive
pulley and pull the shaft away from the
pulley.
2. Detach the belt from the pulley and take
it out through the space between the
pulley and the shaft.

4
Detach the belt from the conveyor.
After you have detached the belt, clean the
clearance between the conveyor frame
and board guide with a fine brush or cloth
rag.
5
Attach a new belt.
1. Temporarily fit a new belt onto the pulley.
2. Reconnect the shaft to the pulley and
tighten the bolt.
3. Tighten the belt tensioner bolt while
applying a proper tension to the belt by
moving the belt tensioner bolt.
c
CAUTION
Always set the belt tensioner (pulley) tightening torque
at 5.5N•m.
6
Check the belt rotating condition.
1. Cancel emergency stop.
2. On the [Unit]-[Conveyor] tab, press the
[Left] and [Right] buttons to turn on the
conveyor motor and check the belt
rotation.
3. If the rotation speed fluctuates or there is
slack in the belt, adjust the position of
the tensioner bolt and then check the
rotation again.
