TO STOP
ENGINE
• To stop engine, release operator pres-
ence control bar.
NOTE: In cooler weather it may be neces-
sary 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 attempt-
ing to start and do not repeat priming
steps.
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 prod-
uct 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
usually necessary when starting an
engine which has already run for a few
minutes.
2. Hold operator presence control bar
down to the handle and putt starter
handle quickly. Do not allow starter
rope to snap back.
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 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 tess 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 wilt 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 wilt 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 wilt 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
wilt 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.
MAX 1/3
• 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 wilt help prevent matting and
graining of the lawn.
