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. Move throttle control lever to FAST
position.
3. Hold operator presence control bar
down to the handle and pull starter
handle quickly. Do not allow starter
rope to snap back.
TO STOP ENGINE
• To stop engine,
release
operator
presence
control
bar.
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
• 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.
9
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 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 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
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.
