GAS:
• Fill gasoline tank with fresh, clean unleaded
gasoline. DO NOT USE PREMIUM GASOLINE.
BE CAREFUL NOT TO OVERFILL TANK (SEE
FIG. 8).
WARNING: Experience indicates that alcohol blend-
ed fuels (called gasohol or using ethanol or methanol)
can attract moisture which leads to separation and
formation of acids during storage. Acidic gas can
damage the fuel system of an engine while in storage_
To avoid engine problems, the fuel system shouldbe
emptied before storage for 30 days or longer° Drain
the gas tank, start the engine and let it run until the
fueliines and carburetor are empty. Use fresh fuel

MOWINGTIPS
OPERAr!ON
• Under certain conditions, suchas very tall grass,
it may be necessary to raise the height of cutto
reduce pushing effort and to keep from
overloading the engine and leaving clumps of
grass clippings.
• For extremely heavy cutting, reducethe wtdth of
cut and raise the rear of the lawn mower hous-
ing one (1) wheel adjuster setting higher than the
front for better discharge ofgrass. .
o For better grass bagging andmost cutting con-
ditions, the engine speed should be set in the
"HIGH" (FAST) position.
• When using a rear discharge lawn mower in
moist, heavy grass, clumpsof cut grass may not
enter the grass catcher_ Reduce ground speed
(pushingspeed) and/or run the lawn mower over
the area a second time.
• If a trail of grass clippings isleft on the right side
of a rear discharge lawn mower, mow in a
clockwise direction with a small overlap to col-
lect the clippings on the next pass.
o Pores in cloth grass catchers can become filled
with dirt and dust with useand catchers will col-
lect lessgrass. To prevent this,regularly hosecat-
cher off with water and let dry before using.
. Keep top of enginearound starter clear and clean
of grassclippings and chaff. Thiswdi help engine
air flow and extend engine life_

I_PORTAHT:
IT IS IMPORTANT TO PREVENT
GUM DEPOSITS FROM FORMING
IN ESSENTIAL FUEL SYSTEM PARTS
SUCH AS THE CARBURETOR, FUEL
FILTER, FUEL HOSE, OR TANK
DURING STORAGE. ALSO, EX-
PERIENCE INDICATES THAT ALCO-
HOL BLENDED FUELS (CALLED
GASOHOL OR USING ETHANOL
OR METHANOL) CAN ATTRACT
MOISTURE WHICH LEADS TO
SEPARATION AND FORMATION
OF ACIDS DURING STORAGE.
ACIDIC GAS CAN DAMAGE THE
FUEL SYSTEM OF AN ENGINE
WHILE IN STORAGE_
FIG. 16
OTHER

° Replace your gasoline can if your can starts to
rust° Rust and/or dirt in your gasoline can cause

densation to form and car_ cause your lawn
mower to rust.
o When setting up your Handle from the storage
position,the Lower Handle will automatically lock
into the mowing position.
