5. Maintenance of Your Projector
2. Remove the air filter.
(1) Turn the screws at the 2 locations counterclockwise to
remove them.
(2) Bend the air filter slightly to detach the 2 tabs
from the grooves on the main unit before
removing the air filter.
Caution: If you bend the metal filter too much
with a strong force, it may bend and break,
thus becoming unusable. Be very careful and
bend it just a little.
3. Use a vacuum cleaner to remove the dust.
Use a vacuum cleaner to suck up the dust from both sides of the air filter and the front and back of the side
cover.
Air filters are also provided on the projector. They cannot be removed. Use a vacuum cleaner with a nozzle
attachment to clean dust from the air filters.
Note: Do not press the nozzle of the vacuum cleaner strongly against the projector. Doing so could damage the
wings of the radiator.
