Properly cleaned and installed air cleaner
elements are the best guarantee to continued
long and satisfactory 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 accumulated 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.
NOTE: This machine is designed to cool properly
with the engine side panels in place. Operating
the machine without panels in place may result in
inadequate cooling.
SPARK PLUGS
Cleaning Spark Plug
Clean spark plugs with a penknife or wire brush
and solvent. If electrode is burned away or the
porcelain is cracked, replace with new plug.
NOTE: Do not sandblast or use any abrasive
machines to clean spark plugs; because any grit
introduced into the engine could cause severe
damage.
LIGHTS
The headlights are sealed-beam units. Refer to
"SPECIFICATIONS" when replacement is
necessary.
To replace the taillight lamp, remove socket and
bulb from the back of the taillight by rotating
socket 1/4 turn. Refer to "SPECIFICATIONS".
FUSES
Always use the same capacity fuse for replace-
ment. Refer to "SPECIFICATIONS." If the lights
fail or the electric clutch does not engage, check
the appropriate fuse.
To install a new fuse, press in on the fuse housing
cap and turn counterclockwise to remove it from
the fuse housing. Remove the old fuse and
replace it with a new one. Then reassemble the
cap to the housing.
NOTE: The fuse on the left is for the lights; the
fuse on the right is for the electric clutch.
