SERVICING PAPER CARTRIDGE
This engine is equipped with a dry type air cleaner
element, which should be checked every 100 oper¬
ating hours and replaced if dirty. It should be checked
and if necessary replaced more often under extremely
dirty, dusty conditions. Do not wash element in any
liquid or attempt to blow dirt off with air hose as this
will puncture filter element. Carefully handle new ele¬
ment — do not use if gasket surfaces are bent or
twisted. Check the following when installing a new
element: (Refer to Figure 27.)
1.
Backplate must be fiat on gasket of carburetor
elbow. Replace backplate if bent or cracked.
2.
Gasket surfaces of element must be flat against
backplate and covered to seal effectively.
3.
Seal on cover must be in place to reduce noise
and vibration of the cover. Vibration can cause
stud hole in cover to enlarge, thus permitting dirt
to enter carburetor.
4. Wing nuts must be finger tight — do not over¬
tighten.
Properly cleaned and installed air cleaner elements
are the best guarantee to continued long and satisfac¬
tory engine life.
