ENGINE COOLING
Incoming air for combustion is filtered by a
dry-type air cleaner having a filter element inside
of the cover.
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 accumulated dirt and trash or engine will
overheat and result in damaged moving parts.
Periodic cleaning with compressed air will keep
area clear for adequate cooling.
Clean or replace the element when loss of power is
noticeable. Replace at least once a year.
Cleaning the Element -To clean the element,
remove wing nut, air cleaner cover, then remove
element and tap it lightly on a flat surface to cause
loose dirt to falloff. Handle paper element with
care to avoid dents or crushing local areas. Do not
use compressed air to remove dirt as this can
repture the element. Do not wash or use a solvent.
DRY TYPE AIR CLEANER
Replacing the Element -Replace element with a
new one if dirt does not drop off easily, or if it is
bent or damaged. When replacing element be sure
the back plate is securely tightened to the carbu-
retor. Replace the back plate if bent or cracked,
then be sure the element fits snugly around the
inside edge of the air cleaner base. The gasket
surfaces of the element must be flat against the
back plate and cover to seal effectively. Replace
cover and tighten wing nut finger tight.
Removing the air cleaner filter element.
The twelve-volt electrical system consists princi-
pally of a motor-generator, voltage regulator, and a
twelve-volt battery.
NOTE: When the engine is not operating, the key
must be turned to the "OFF" position to prevent
battery discharge.
SAFETY STARTING SWITCH
All connections must be clean and securely
fastened.
The safety starting switches activated by the
clutch-brake pedal and the power take-off clutch
lever serve to prevent starting the engine acci-
dentally.
IGNITION SWITCH
Turn the key clockwise to turn on the ignition. A
further turn actuates the motor-generator. The key
cannot be removed when in the "ON" position.
