avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. Emptythe gas tank, start
the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
next season. See Storage Instructionsfor
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanentdamage may occur.
TO STOP ENGINE
• To stop engine, release operator pres-
ence control bar.
TO START
ENGINE
NOTE: Due to protective
coatings on the
engine, a small amount of smoke may be
present during the initial use of the product
and should be considered
normal.
1. To start a cold engine, push primer
three (3) times before trying to start.
Use a firm push. This step is not usu-
ally necessary when starting an engine
which has already run for a few minutes.
2. Hold operator presence control bar down
to the handle and turn the start key.
IMPORTANT:
Do not crank engine more
than five continous seconds between each
time you try to start. Wait 5 to 10 seconds
between each attempt.
• To start engine using the rope starter,
follow the steps above. Exchange the
use of the starter rope for start key.
Pul! starter handle quickly. Do not allow
starter rope to snap back.
NOTE: In coolerweather
itmay be necessary
to repeat priming steps. In warmer 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
_i, CAUTION:
Do not use de-thatcher
blade attachments
on your mower. Such
attachments
are hazardous,
wil! 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 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 cut-
ting 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. See "CLEANING"
in the
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 recut-
ting 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, yet the newly cut area will not be
exposed to direct sunlight.
• 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 grass, reduce your width of cut
by overlapping
previously cut path and
mow slowly.

• 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 sec-
ond cut, mow across (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.
