OPERATION
system of an engine while in storage. To avoid engine
problems, the fuel system should be emptied before stor­
age of 30 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 Instruc­
tions for additional information. Never use engine or
carburetor cleaner products in the fuel tank or permanent
damage may occur.
A
CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.
TO START ENGINE (See Fig. 7)
This engine on this product is designed for maximum
perfomance and life if operated with the choke (|\|) fully
open and the throttle control in the fast (^) position. To
open the choke fully requires an engine warm-up period of
several seconds to several minutes, depending on the
temperature.
After starting the engine, first open the choke slowly until
the engine just begins to run smoothly. Then open the
choke in small steps, allowing the engine to accept small
changes in speed and load, until the choke is fully open.
During engine warm-up, the equipment can be operated.
When starting engine for the first time or if engine has run
out of fuel, it will take extra cranking time to move fuel from
the tank to the engine.
• Depress clutch/brake pedal and set parking brake.
• Place gearshift (ever in neutral (N) position.
• Move attachment clutch to “DISENGAGED” position,
• Move throttle control lever to choke (|\|} position for
cold engine start. For warm engine start, move throttle
control to fast (4») position.
• Insert key into ignition and turnkey clockwise to “START’
position and release key as soon as engine starts. Do
not run starter continuously for more than fifteen
seconds per minute. If engine does not start after
several attempts, move throttle control to fast (4i)
position, wait a few minutes and try again.
® When engine starts, move throttle control to desired
position.
• Allow engine to warm up for a few minutes before
engaging drive or attachments.
NOTE: If at a high altitude (above 3000 feet) or in cold
temperatures (below 32°F), the carburetor fuel mixture
may need to be adjusted for best engine performance. See
‘TO ADJUST CARBURETOR” in the Service and Adjust­
ments section of this manual.
MOWING TIPS
“ Tire chains cannot be used when the mower housing
is attached to tractor.
® Mower should be properly leveled for best mowing
performance. See ‘TO LEVEL MOWER HOUSING” in
...... the Service and Adjustments section of this manual.'"'
® The left hand side of mower should be used for trim­
ming.
• Drive so that clippings are discharged onto the area
that has been cut. Have the cut area to the right of the
machine. This will result in a more even distribution of
clippings and more uniform cutting.
• When mowing large areas, start by turning to the right
so that clippings will discharge away from shrubs,
fences, driveways, etc. After one or two rounds, mow
in the opposite direction making left hand turns until
finished (See Fig. 10 ).
If grass is extremely tall, it should be mowed twice to
reduce load and possible fire hazard from dried clip­
pings. Make first cut relatively high; the second to the
desired height.
Do not mow grass when it is wet. Wet grass will plug
mower and leave undesirable clumps. Allow grass to
dry before mowing.
Always operate engine at full throttle when mowing to
assure better mowing performance and proper dis­
charge of materia). Regulate ground speed by select­
ing a low enough gear to give the mower cutting
performance as well as the quality of cut desired.
When operating attachments, select a ground speed
that will suit the terrain and give best performance of
the attachment being used.
MULCHING MOWING TIPS
IMPORTANT: FOH BEST PERFORMANCE. KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH. CLEAN AFTER EACH USE.
® 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 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 mower cutting height so that
the mower cuts off only the top one-third of the grass
blades (See Fig. 11). For extremely heavy mulching,
reduce your width of cut and mow slowly.
• Certain types of grass and grass conditions may re­
quire that an area be mulched a second time to com­
pletely 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.
