BEFORE
STARTING
THE ENGINE
CHECK ENGINE OIL LEVEL
The engine
in your tractor
has been shipped,
from the factory,
already
filled
with summer
weight
oil.
1.
Check
engine
oil with tractor
on level
ground.
2.
Remove
oil fill cap/dipstick
and
wipe
clean, reinsert
the dipstick
and screw cap
tight, wait for a few seconds,
remove
and
read oil level.
If necessary,
add oil until
"FULL'
mark on dipstick
is reached.
Do
not overfill.
• For cold
weather
operation
you
should
change
oil for easier
starting
(See the oil
viscosity
chart in the Maintenance
section
of this manual).
• To change
engine oil, seethe
Maintenance
section
in this manual.
ADD
GASOLINE
• Fill fuel tank to bottom
of filler
neck.
Do
not
overfill.
Use
fresh,
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.
Purchase
fuel in quantities
that
can be used within 30 days to assure
fuel
freshness.
_CAUTION:
Wipe off any spilled
oil or fuel.
Do not store,
spill or use gasoline
near an
open flame.
IMPORTANT:
When
operating
in tempera-
tures
below
32°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
fue!
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.
