OPERATION
GAS
• Fill fusi tank. Use fresh,, clean, regular unteaded
gasoline with a minimum of 87 octane, (Use of leaded
gasoline will increase carbon and lead orride deposits
and reduce valve life}, Do not mix oil with gasoline.
Purchase fuel in quantities that can be used withlri 30
days to assure fuel freshness. , ,,
WARNING: Experience indicates that alcohol blended
fuels {called gasohol or using ethanol or melhanoi) can
attract moisture which leads to separation and formation of
adds during storage. Acidic gas can damage the fuel
system pi an erìgine while in, storage. Jp avoid engine
problems, the fuel system should be emptied before stor­
age of 30 days’ or longer. Drain the fuel tank, start the

MOWING TIPS
• Under certain conditions, such as very tall grass, i! may
be necessary to raise the height of cut to reduce
pushing effort and to keep from overloading the engine
and leaving clumps of grass clippings.
• For extremely heavy cutting, reduce the width of cut
and raise, the rear of the lawn mower housing one (1 )
vrh'eel adjuster setting higher than the front for better
discharge of grass.
'
• For better grass bagging and most cutting conditions,
the engine -speed should be set In the fast (%) posi­
tion. -
• When using a rear cSscharge lawn riiower In moist,
heavy grass, clumps of cut grass may not enter the
grass catcher: Reduce ground speed (pushing speed)
and/or run the lawn mowerover tnearea a second time.
• if a trail of grass clippings is left on the right side of a rear
discharge lawn mower, mow in a clockwise,direction
with a small overlap to còlteci the clipptogs on the next
pass.' ■
‘ '
•• keep top of engine around starter, clear arid clean of
grass clippings and chaff. This will help engine airflow
and extend engine life
