7.4 Cleaning the air cleaner
A dirty air cleaner obstructs the flow of air to the carburetor. To prevent
carburetor malfunctions, clean the air cleaner on a regular basis. Clean
the filter more frequently if the engine is operated in an extremely dusty
environment.
Warning: Never use gasoline or cleaning solutions with a low flash point to
clean the air cleaner cartridge. This could cause a fire or worse an explo-
sion.
Caution: Never run the engine without an air cleaner. This leads
to undue engine wear.
1. Remove the wing nuts and the air cleaner cap. Take out the ele-
ments and separate them. Check both elements for holes or tears
and replace them as needed.
2. Foam element: Wash out the element in warm soap water, rinse it
and allow it to completely dry. If necessary, wash out the element in
a cleaning solution with high flash point and allow it to dry.
3. Paper element: Tap the element lightly against a hard surface a few
times to loosen excess dirt. Never attempt to brush off the dirt, since
this will rub the dirt into the fibers. Replace the paper element if it is
very dirty.
Cleaning the cyclone housing:
If dirt accumulates in the cyclone housing, unscrew the three special
flat head screws and wipe the components or rinse them with water.
Then completely dry off the components and assemble them carefully.
Caution:
∗ During the reassembly of the cyclone, make sure that the cloth of the
air inlet fits properly into the groove of the preliminary filter cap.
∗ Install the air horn in the correct direction.
7.5 Cleaning the filter cup
Close the fuel tap. Remove the filter cup with the o-ring and wash it out
with non-combustible and low-flammable solvent. Allow it to complete-
ly dry, then reinstall it and tighten it firmly. Open the fuel tap and check
for leaks.
