6. Maintenance
Important: shut-off power from the host machine before starting any cleaning activities.
6.1. Removing and re-installing the hopper
The hopper can easily be removed by pressing on the yellow release button on the mounting plate
and then removing the connector.
Re-installing the hopper:
First plug the connector into the Hopper at the reverse side and slide it into the two yellow hooks on
the mounting bracket, then press the yellow button with lever slightly backwards and push the hopper
onto the bracket.
6.2. Cleaning and Materials
All reachable places where the coins pass through the hopper should be cleaned
at least every 6 months or after counting 500,000 coins (whichever situation occurs first)
with a moist cloth with dry silicon spray (Part No. 20-0124-1).
In particular the opto coupler needs to be kept clean.
Dirt could obstruct or disrupt the optic signal, resulting in unreliable coin counting.
