TO START ENGINE
To start a cold engine, push primer three
(3) times before tryingto start. Use a firm
push. This step is not usually necessary
when starting an engine which has
already run for a few minutes.
Move throttle control lever to fast
position.
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, 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.
When using a rear discharge lawn
mower in moist, heavy grass, clumps of
cut grass may not enter the grass
catcher. Reduce ground speed
(pushing speed) and/or run the lawn
mower over the area a second time.
If a trail of clippings is left on the right
side of a rear discharge mower, mow in
a clockwise direction with a small
overlap to collect the clippings on the
next pass.
o
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 Maintenance section
ofthis 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 isthe early aftemoon. 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 heightso that the lawn mower cuts
offonly the top one-thirdof the grass blades.
Ifthe lawn isovergrown itwillbe necessary
to raisethe heightofcut to reduce pushing
effortand to keep from overloading the
engine and leavingclumps of mulched
grass. Forextremely heavy mulching,
reduce your widthof cutby overlapping
previouslycut path and mow slowly.
Certain types ofgrass and grass conditions
may require that an area be mulched a
second time to completely hide the
clippings. When doing a second cut, mow
acrossor perpendiculartothe first cut path.
Change yourcuttingpattern from week to
week. Mow northto south one week then
change to east to west the next week. This
willhelp prevent matting and graining ofthe
lawn.
