1.2 How to clean the air filter

with clean water or vacuum it
with an electric vacuum cleaner.
1. Cleaning the air filter

clean the front panel or it may
become discolored.

thinner, polishing compound,
machine oil, etc. when cleaning
the front panel, or paint may peel
off, or it may become deformed or
damaged.
Note: Once the air filter is washed,
dry it completely before returning it
to its original position.
After cleaning, be sure to return it to
its original position.
