SERVICING PAPER CARTRIDGE
This engine is equipped with a dry type air cleaner
element, which should be checked every 100 operat¬
ing hours and replaced if dirty. It should be checked
and
if
necessary
replaced
more
often
under
extremely dirty, dusty conditions. Do not wash ele¬
ment in any liquid or attempt to blow dirt off with air
hose as this will puncture filter element. Carefully
handle new element — do no! use if gasket surfaces
are bent or twisted. Check the following when instal¬
ling a new element: (See Figure 26.)
1
.
Backplate must be flat 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.

tighten.
Properly cleaned and Installed air cleaner elements
are the best guarantee to continued long and satisfac¬
tory engine life.
CLEANING ENGINE

able to circulate freely around the engine, through the
screen, shroud, and over the fins of the cylinder head
and cylinder block. Keep these areas free of accu¬
mulated dirt and trash or engine will overheat and
result in damaged moving parts. Periodically clean
the inside of the side panels and grille for adequate
cooling.
■i^NOTE
This machine is designed to cool properly
with the engine side panels in place. Oper¬
ating the machine without panels in place
may result in inadequate cooling.
