ADD GASOLINE
• Fill fuel tank to bottom
of tank filler neck.
Do not overfill.
Use fresh, clean,
regular
unleaded
gasoline
with a minimum
of
87 octane.
Do not mix oil with gasoline.
Purchase
fuel in quantities
that can be
used within 30 days to assure
fuel fresh-
ness.
A CAUTION:
Wipe off any spilled
oil or
fuel.
Do not store,
spill or use gasoline
near an open flame.
A CAUTION:
Alcohol
blended
fuels
(called gasohol
or using ethanol
or metha-
nol) 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
should
be emptied
before storage
of 30
days or longer.
Empty
the gas tank, start
the engine
and let it run until the fuel lines
and carburetor
are empty.
Use fresh fuel
next season.
See Storage

MOWING
TIPS
A CAUTION:
Do not use de-thatcher
blade attachments
on your mower.
Such
attachments
are hazardous,
will damage
your mower
and could void your warranty.
• Under certain
conditions,
such as very
tall grass,
it 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 clip-
pings. It may also be necessary
to re-
duce ground
speed
and/or
run the lawn
mower over the area a second
time.
• For extremely
heavy cutting,
reduce
the
width of cut by overlapping
previously
cut path and mow slowly.
• For better grass bagging
and most cut-
ting conditions,
the engine
speed
should
be set in the FAST position.
• Pores in cloth grass catchers
can be-
come filled with dirt and dust with use
and catchers
will collect
less grass. To
prevent
this, regularly
hose catcher
off
with water and let dry before
using.
• Keep top of engine
around
starter
clear
and clean of grass
clippings
and chaff.
This will help engine
air flow and extend
engine
life.
