TO START ENGINE
GAS (See Fig. 11)
,
To start a cold engine, push primer five (5) 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.
Fill gasoline tank with fresh, clean unleaded gasoline.
DO NOT USE PREMIUM GASOLINE. BE CAREFUL
NOT TO OVER FILL TANK.
WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storage.
To avoid engine problems, the fuel system should be
emptied before storage for30 days or longer. Drain the gas
tank, start the engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel next season. See
Storage instructions for additional information.
Never use engine or carburetor cleaner products in the fuel
tank or permanent damage may occur.
•
Push engine speed control lever to HIGH (,_)

Hold operatorpresence 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,

ATION
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.
•
For extremely heavy cutting, reduce the width of cut
and raise the rear of the lawn mower housing one (1)
wheel adjuster setting higher than the front for better
discharge o_ grass.
For better grass bagging and most cutting conditions,
the engine speed should be set in the '"HIGH" (_)
(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 grass clippings is left on the right side of a
rear discharge lawn mower, mow in a clockwise
direction with a small overlap to collect the clippings
on the next pass.
•
Keep top of engine around starter clear and clean of
grass clippings and chaff. This will help engine air
flow and extend engine life.
FiG, 12
*
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 (See Fig. 12). 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,
mow slowly and raise the rear of the lawn mower one
wheel adjuster setting higher than the front.
o
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 perpendicular 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.
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 catchers off
with water and tet dry before using.
MULCHING
MOWING
TIPS
IMPORTANT:
FOR BEST PERFORMANCE,
KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH. CLEAN AFTER EACH USE. SEE "CLEANING"
IN CUSTOMER RESPONSIBILITIES 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.
