Maintenance check list, problem
prevention and day-to-day fixes
Every two weeks (recommended):
- check the air pressure of the bag. It should be NO MORE
than 2psi,
- check if the bag is not rotating about its own axis. If it is, see
point d) in this section,
- check the position of the arm protector. See point h) in this
section,
- check all of the connections on the main board,
- check the level/balance of the machine. If needed use
adjusting legs under the machine to bring the machine to
level,
- check if the usage instructions are readable.
Every month:
- check mounting cover screws/nuts,
- check the lubrication of the mechanism. For the instructions
see point c) in this section,
- check the display lights,
- clean the coin/ bill acceptor.
a)
Coin acceptor maintenance
Coin acceptor should be cleaned periodically (every 2000 - 3000
credits). Best way to clean it is by using simple cloth slightly soaked
in distilled alcohol. Focus should be placed on cleaning the area
where coins slide thru (make sure sliding part is in open position).
b) Sound volume regulation
Volume potentiometer (see Main Board Layout, back side) used to
control volume is placed on the top right side of the electronic board.
The volume adjustment can be done by rotating the potentiometer to
the left or right.
