attract moisture which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storager To avoid engine
problems, the fuel system should be emptied before stor-
age of 30 days or longer. Drain the fuel tank, start the
engine and let it run until fuel Iines and carburetor are

MOWING TiPS
o Under certain conditions, such as very tall grass, itmay
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.
= For'extremely heavy cutting, reduce the width of cut by
overlapping previously cut path and mow SloWlyr
O For better grass bagging and most cutting conditions,
the engine speed should be set in the fast (,_) posi-
tion..
= When using a rear discharge lawn mower in moist,
heavy grass, clumps of cut grass may not enter the
grasscatchero Reduce ground speed (pushing speed)
and!o r runthe lawn mower' over the area a second time.
o 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.
•Pores in cloth grass catchers can become filled with dirt
and dust with use and catchers willcollect 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 airflow
and extend engine life.

MULCHING MOWING TIPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH_ SEE "CLEANING" IN CUSTOMER
RESPONSIBILITIES SECTION OF THIS MANUAL
"The special mulching blade will recut the grass clip-
pings many times and reduce them in size so that as
they fall onto the lawn they will disperse into the grass
and not be notice& 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
bladeso
o Avoid cutting your lawn when it isweL 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 (See Fig. 11). If the lawn is
overgrown it wil! be necessary to raise the height of cut
to reduce pushing effort and to keep from overloading
the engine and leaving clumps of mulched gras& For
extremely heavy mulching, reduce your width of cut by
0verlapplng previously cut path and mow slowly°
• Certain types of grass and grass conditions may re-
quire that an area be mulched a second time to
completely hide the clippings. When doing a second
cut, mow across or perpendicular to the first cut path.
o Change your cutting pat!ern from week to week. Mow
north to south one week _.nenchange to east to west the
next week. This will help prevent matting and graining
of the lawn.
