liquid or attempt to blow dirt off with air hose as this
will puncture fitter element. Carefully handle new ele¬
ment — do not use if gasket surfaces are bent or
twisted. Check the following when installing a new
element: (See Figure 32.)
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.
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.
CLEANING ENGINE
This tractor has an air-cooled engine. Air must be
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 accumu¬
lated dirt and trash or engine will overheat and result
in damaged moving parts. Periodically clean the
inside of the side panels and grille insert for adequate
cooling.
Hl^ 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.

tion.
