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 pul! 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
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. 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 grass,
reduce your
width of cut by overlapping
previously
cut path and mow slowly.
MAXI_
• 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.
