Maintenance
Your projector needs little maintenance. You should keep the 
lens clean because any dirt or smears appear on the screen. 
You also need to periodically clean the air filter. A clogged air 
filter can block ventilation needed to cool the projector and 
keep it from overheating.
The only parts you should replace are the lamp and air filter. 
If any other part needs replacing,...

filter, follow these steps:
1. Turn off the projector and unplug the power cable.
2. Stand the projector with the lens at the top.
