Fuel Filter Service
The fuel filter cannot
be cleaned
and must be replaced
once a
year or every 100 operating
hours; more often if run with old
gasoline.
1.
Remove all fuel from tank by running
engine until it stops
from lack of fuel
2.
Remove c-clamp from fuel line and remove fuel line from
tank outlet. See Fig. 10-5.

3.
Pull out old fuel filter from tank outlet.
Replace when dirty
or damaged.
4.
Grasp new fuel filter from shouldered
end and insert it
completely
to the shoulder
into the tank outlet.
See Fig.
10-5 inset.
5.
Replace fuel line and c-clamp.
Clean Engine
If the engine
has been running,
allow it to cool for at least half
an hour before cleaning.
Periodically
remove
dirt build-up
from
engine. Clean finger
guard and around
mufflen
Clean with a
brush or compressed
air.
IMPORTANT: Do not spray engine with water to clean because
water could contaminate
fuel. Using a garden hose or pressure
washing
equipment
can also force water into the air cleaner or
muffler
opening.
Water in the air cleaner will soak the paper
element,
and water that passes through
the element
or muffler
can enter the cylinder,
causing damage.
WARNING:
Accumulation
of debris
around
muffler
could
cause a fire.
Inspect
and
clean
before
every
use.
Storage
Engines stored between
30 and 90 days need to be treated
with
a gasoline
stabilizer
and engines stored over 90 days need to be
drained
of fuel to prevent
deterioration
and gum from forming
in fuel system or on essential
carburetor
parts. If the gasoline
in
your engine deteriorates
during
storage, you may need to have
the carburetor,
and other fuel system components,
serviced or
replaced.
1.
Remove all fuel from tank by running
engine
until it stops
from lack of fuel.
WARNING:
Never leave engine unattended
while
running.
2.
3.
Change oil. See Oil Change section.
Remove spark plug and pour about
1/2 an ounce of engine
oil into cylinder.
Replace spark plug and crank slowly to
distribute
oil.
4.
Clean debris from around
engine, under finger
guard, and
under, around and behind
muffler.
Touch up any damaged
paint, and coat other areas that may rust with a light film
of oil.
S.
Store in a clean, dry and well ventilated
area away from any
appliance
that operates
with a flame or pilot light, such
as a furnace, water heater, or clothes
dryer. Also avoid any
area with a spark producing
electric
motor, or where power
tools are operated.
6.
If possible,
also avoid storage
areas with high humidity,
because that promotes
rust and corrosion.
7.
Keep the engine level in storage. Tilting
can cause fuel or
oil leakage.
Removing From Storage
1.
Check your engine as described
in the Pre-Operation
Check section
of this manual.
2.
If the fuel was drained
during
storage
preparation,
fill the
tank with fresh gasoline.
If you keep a container
of gasoline
for refueling,
make certain it contains
only fresh fuel.
Gasoline
oxidizes and deteriorates
over time, causing hard
starting.
3.
If the cylinder
was coated with oil during
storage
preparation,
the engine will smoke briefly at startup.
This
is normal.
