• To change engine oil, see the Maintenance
section
in this manual.
ADD GASOLINE
• Fill fuel tank to bottom of filler neck. Do not
overfill.
Usefresh,
clean, regular unleaded
gasoline
with a minimum
of 87 octane.
(Use of
leaded
gasoline
will
increase
carbon and lead oxide deposits and reduce
valve life).
Do not mix oil with gasoline.
Purchasefuel
in quantitiesthat
can be used
,_woithin 30 days to assure
fuel freshness.
AUTION:
Wipe
off any spilled
oil or
fuel.
Do not store, spill or use gasoline
near
an open flame.
IMPORTANT:
When operating
in tempera-
tures below32°F(0°C),
use fresh, clean winter
grade
gasoline
to help
insure
good
cold
weather
starting.
CAUTION:
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
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
Instructions
for additional
information.
Never use engine
or carburetor
cleaner products
in the fuel tan k
or permanent
damage
may occur.
TO START
ENGINE
When starting
the engine for the first time or
if the engine
has run out of fuel, it will take
extra cranking
time to move fuel from the
tank to the engine.
1. Sit on seat in operating
position,
depress
clutch/brake
pedal and set parking brake.
2.
Placegearshiftleverin
neutral(N) position.
3.
Move attachment
clutch
to disengaged
position.
4.
Move throttle
control to choke position.
NOTE:
Before starting,
read the warm and
cold starting
procedures
below.
5.
Insert
key
into
ignition
and
turn
key
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 the engine
does
not start
after several
attempts,
move
throttle
control
to fast position,
wait a
few minutes
and try again. If engine still
does not start, move the throttle
control
back to the choke position
and retry.
WARM WEATHER STARTING (50 ° F and above)
6.
When
engine
starts,
move the throttle
control to the fast position.
• The attachments and ground drive can nowbe
used. Ifthe engine does not acceptthe load, re-
start the engine and allow it to warm up for one
minute using the choke as described above. 15
COLD WEATHER STARTING ( 50 ° F and below)
6.
When engine starts, leave throttle control
in choke position
until engine warms
up
and begins to run roughly. Once rough run-
ning begins, immediately
move the throttle
control to the fast position. Engine warm-up
may take fTom several seconds to several
minutes
(the colder the temperature,
the
longer the warm-up).
• The attachments
can also be used during
the engine warm-up
period.
NOTE: If at a high altitude (above 3000 feet) or
in cold temperatures
(below 32 F) the carbure-
tor 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
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 trimming.
• Drive so that clippings
are discharged
onto
the area that has already
been cut. Have
the cut area to the right of the tractor. This
will result in a more even distribution
of
clippings
and more uniform cutting.
• When mowing large areas, start byturning
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.
f
_272
• If grass
is extremely
tall,
it should
be
mowed twice to reduce load and possible
fire hazard
from
dried clippings.
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 undesir-
able clumps.
Allow
grass to dry before
mowing.
• Always
operate
engine
at full throttle
when
mowing
to assure
better mow-
ing performance
and proper
discharge
of material.
Regulate
ground
speed
by
selecting
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.
