11 Care and maintenance
T
he M4000 multiple light beam safety device is maintenance-free. The front screen of the
M4000 multiple light beam safety device should be regularly cleaned and also if contami-
nated.
 Do not use aggressive detergents.
 Do not use abrasive cleaning agents.
Static charges cause dust particles to be attracted to the front screen. You can prevent
this effect by using the antistatic plastic cleaner (SICK Part No. 5600006) and the SICK
lens cloth (SICK Part No. 4003353).
How to clean the front screen:
 Use a clean and soft brush to remove dust from the front screen.
 Now wipe the front screen with a clean and damp cloth.
 After cleaning, check the position of sender and receiver to ensure that the protective
device cannot be bypassed (reaching over, under or standing behind).
 Verify the effectiveness of the protective device as described in chapter 9.3 “Test
notes” on page 100.
