Maintaining and 
Transporting the Projector
Your projector needs little maintenance. All you need to do on a 
regular basis is keep the lens clean. Any dirt or smears on the lens may 
show up on your projected image. 
You also need to periodically clean the air filter on the bottom of the 
projector. A clogged air filter can block ventilation needed to cool the 
projector and cause overheating. 
The only parts you should replace are the lamp and air...
