6.2.4 Cleaning and care
Safety: BEFORE YOU BEGIN; SWITCH OFF THE POWER SUPPLY TO THE VENDING MACHINE
Dirt is a major cause of malfunctioning and therefore cleaning is a prominent aspect of field servicing. Apart from general cleaning near the CF7900, the coin path,
dispenser arms and guides must also be cleaned on a regular basis.
Cleaning material to be used: Use only a damp cloth, cotton buds or a soft brush with a foam cleaner (i. e. Aberclens or similar).
DO NOT USE SOLVENTS OR ABRASIVES
Cleaning the coin checker module
The coin checker module of the CF7900 combines the coin path, accept gate, the rout-
ing gates and reject path.
• Open the coin checker by pulling on the left-hand side and lifting upwards and to
the right. Note: The coin checker lid does not remain open and may trap fingers if
released.
• Clean the areas shown on the right, leaving the surfaces clean and dry.
• Do not scratch or damage the coin path as this will lead to poor acceptance.
• Ensure lid closes completely after cleaning.
