Maintenance

allowed to be opened by authorised service personnel.
7.1
Maintenance during operation
The NAV350 is maintenance-free apart from the maintenance measures listed below. No
maintenance is necessary to ensure the retention of laser class 1.
Recommendation
To obtain the full optical power of the NAV350, the window in the scanner head of the
NAV350 should be regularly checked for contamination. This applies particularly in harsh
operating environments (dust, powder, moisture).
Damage to the optics in the NAV350!
The window in the scanner head on the NAV350 is made of glass. The optical power is re-
duced by scratches and smearing on the front screen.
Do not use aggressive detergents.
Do not use abrasive cleaning agents.
Only use fabric cleaning cloths or paper towels free of wood and fluff.
Avoid scratching and scouring movements on the window.
Performance reduction due to contamination of the window in the scanner head!
Static charges cause dust particles to be attracted to the window of the NAV350. You can
prevent this effect by using the antistatic plastic cleaner (part no. 5600006) and the SICK
lens cloth (part no. 4003353).
