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
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 racutting 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.
