DRIVE CONTROL
ADD GASOLINE
o Self-propelling is controlled by holding
the operator presence control bar down
to the handle and pushing the drive
control lever forward until it clicks; then
release the lever°
= Forward motion wilt stop when the
operator presence control bar is
released. To stop forward motion
without stopping engine, release the
operator presence control bar slightly
until the drive control disengages. Hold
operator presence control bar down to
handle to continue mowing without selfpropelling.
= To keep drive control engaged when
turning corners, push down on handle
and lift front wheels off ground while
turning lawn mower.
o Fillfuel tank_ Use fresh, clean, regular'
unleaded gasoline with a minimum of 87
octane. Do not mix oilwith gasoline.
Purchase fuel in quantities that can be used
within 30 days to assure fuel freshness_
IMPORTANT: When operating in
temperatures below 32°F(0°C), use fresh,
clean winter grade gasoline to help insure
good cold weather starting.
WARNING: Experience indicates that alcohol
blended fuels (called gasohol or using ethanol
or rnethanol) 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 gas tank, start the engine and let it
run until the 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 the fuel tank or permanent
damage may occur.
CAUTION:
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.

- Check oil level before each use. Add oil if
needed. Fil! to full line on dipstick.
° To read proper level, tighten engine oil cap
each time.
o Reinstall engine oil cap and tighten.
° Change the oil after every 25 hours of
operation or each season° You rnayneed

TO START ENGINE
• To start a cold engine, push primerthree
(3) times before tryingto start. Use a firm
push_ This step is not usually necessary
when starting an engine which has already
runfor a few minutes,
o Hold operator presence control bar down to
the handle and pull starter handle quickly.
Do not allow starter rope to snap back.
o To stop engine, release operator presence
control bar.
NOTE: In cooler weather it may be
necessary to repeat priming steps. In
8
warmew:weather over priming may cause
flooding and engine will not start. If you
do flood engine, wait a few minutes before
attempting to start and do not repeat
priming steps.
MOWING TIPS
o 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 clipping&
o For extremely heavy cutting, reduce the
width of cut and raise the rear of the lawn
mower housing one (1) wheel 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 position°
o When using a rear discharge lawn mower in
moist, heavy grass, clumps of cut grass
may not enter the grass catcher. Reduce
ground speed (pushing speed) and/or run
the lawn mower over the area a second
time_
o 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 collect the clippings on the next pass.
° Keep top of engine around starter clear and
clean of grass clippings and chaff° This will
help engine air flow and extend engine life.
• 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 catchers off with water
and let dry before using.
MULCHING
MOWING
TiPS
IMPORTANT:
For best performance, keep
mower housing free of built-up grass and
trash. 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 fawn 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°
tf 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 by overlapping
previously cut path and mow slowly.
o 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 perpendicular 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.

GENERAL
RECOMMENDATIONS
The warranty on this lawn mower does not
cover items that have been subjected to
operator abuse or negligence. To receive
full value from the warranty, operator must
maintain mower as instructed in this
manual.

periodically to properly maintain your unit.
All adjustments in the Service and
Adjustments section of this manual should
be checked at least once each season.
• Once a year, replace the spark plug,
replace air filter element and check
blade for wear. A new spark plug and
clean/new air filter element assures
proper air-fuel mixture and helps your
engine run better and last longer.
• Follow the maintenance schedule in this
manual.
BEFORE EACH USE
• Check engine oil level,
e Check for loose fasteners.

BEFORE NEX-r OIL CFfANGE
NOTE: A[though mul'd-viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi-viscosity oils will
result in increased oil consumption when
used above 32°F. Check your engine oil
level more frequently to avoid possible
engine damage from running low on oil.
Change after the first 25 hours of operation at
least once a year if the lawn mower is not used
for 25 hours in one year.
Check the crankcase oil level before starting
the engine and after each five (5) hours of
continuous use. Tighten oil plug securely each
time you check the oil level.
