throttle control located on the side of the
upper handle. Choke position is for
starting a cold engine and fast position is
for normal cutting, trimming, and better
grass bagging. Slow position is for light
cutting, trimming and fuel economy.

BEFORE STARTING ENGINE
OIL
Your lawn mower is shipped without oil in
the engine.
• Be sure mower is level and area
around oil fill is clean.
• Remove engine oil cap and fill to the
upper limit mark on dipstick.
NOTE: Allow oil to settle down into
engine for accurate dipstick reading.
• Engine holds 18 1/2 ozs. of oil. For
type and grade of oil to use, see
"ENGINE" in Maintenance section of
this manual.
• Pour oil slowly. Do not over fill.
• Check oil level before each use. Add
oil if needed. Fill to the upper limit mark
on dipstick.
• To read proper level, insert the dipstick
into the tube and rest engine oil cap on
the tube. Do not thread the cap onto
the tube. Remove and read the oil
level.
• Reinstall engine oil cap and tighten.
• Change the oil after every 25 hours of
operation or each season. You may
need to change the oil more often
under dusty, dirty conditions.
ADD GASOLINE
• Fill fuel tank. 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
freshness.
_WARNING: Experience indicates that
alcohol 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. To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer. Drain the fuel tank, start the
engine and let it run until fuel lines and
carburetor are empty. Use fresh fuel next
season. See Storage Instructions for
additional information. Never use engine
or carburetor cleaner products in fuel tank
or permanent damage may occur.
ACAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or use
gasoline near an open flame.

MOWING TIPS
• 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
clippings. It may also be necessary to
reduce 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
cutting conditions, the engine speed
should be set in the fast position.
• Pores in cloth grass catchers can
become 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.
MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean UNDERSIDE OF MOWER
HOUSING after each use. See "Cleaning"
in MAINTENANCE section of this manual.
The special mulching blade will recut
the grass clippings many times and
reduce them in size so that as they fall
onto the lawn they will disperse into the
grass and not be noticed. Also, the
mulched grass will biodegrade quickly
to provide nutrients for the lawn. Always
mulch with your highest engine (blade)
speed as this will provide the best
recutting action of the blades.
Avoid cutting your lawn when it is wet.
Wet grass tends to form clumps and
interferes with the mulching action. The
best time to mow your lawn is the early
afternoon. At this time the grass has
dried and the newly cut area will not be
exposed to the direct sun.
For best results, adjust the lawn mower
cutting height so that the lawn mower
cuts off only the top one-third of the
grass blades. If the lawn is overgrown it
will be necessary to raise the height of
cut to reduce pushing effort and to keep
from overloading the engine and
leaving clumps of mulched grass. For
extremely heavy mulching, reduce your
width of cut, mow slowly and raise
the rear of the lawn mower one wheel
adjuster setting higher than the front.
Certain types of grass and grass
conditions may require that an area be
mulched a second time to completely
hide the clippings. When doing a
second cut, mow across or perpendicu-
lar to the first cut path.
Change your cutting pattern from week
to week. Mow north to south one week
then change to east to west the next
week. This will help prevent matting
and graining of the lawn.
