WARNING:
Never operate the machine without the air filter; dirt
could be sucked in and interfere with the function of the machine.

push in the clips on both sides of the air filter cover and then
pull the cover towards you. (Fig. L).
2. Remove the air filter and clean in water. If the air filter is
soiled, replace with a new air filter.
3. When the air filter is dry, place the air filter back into position,
and re-attach the cover by pushing the clips back into their
slots and the cover is secure.
