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
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 pull starter
handle
quickly.
Do not allow starter
rope to snap
back.
NOTE:
In cooler
weather
it may 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,
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 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.
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 will help prevent
matting
and
graining
of the lawn,
