Generally, wash foam-type filters in
a dishwashing detergent and water
solution. Rinse and wring dry, then
saturate with oil and squeeze out
excess. Failure to re-oil this type
filter will ruin the engine.
Clean paper elements by tapping
lightly. Blowing with air will rupture
paper elements.
Use a flashlight to detect clogged
or torn paper elements – replace if
damaged in any way.
PRIMARY MAINTENANCE
Dirt
can
also
be
introduced into an engine
in
dirty
fuel
from
a
contaminated container.
Always use clean fresh
fuel
from
a
clean
container
to
guard
against dirt, sludge and
water contamination.
Be aware that fuel
breaks
down
storage
and
forms
gummy
compounds
which
will
block
carburetor passages.
Never use fuel more
than 3 months old.
Drain tank then run
the engine out of fuel
before storing during
the off-season.
Failure to keep external surfaces
clean
not
only presents
hazards, but causes overheating
and resulting engine damages
such as:
1.
Distorted valve
guides.
2.
Sticking Valves.
3.
Scuffed, scored
cylinder walls.
4.
Over-speeding.
5.
Loss of power.
6.
Complete failure
of engine.
An engine must also have proper lubrication. All
in
engines use some oil. On 4-cycle engine, CHECK
OIL LEVEL BEFORE EACH START-UP. Wipe area
clean around the oil check plug or dipstick opening
to keep dirt from falling into the engine when
checking the oil. Always check with the machine on
a level surface. On engines with dipstick, keep the
level up to, but not over, the FULL mark. When
adding oil, allow time for all of the oil to flow down
the fill tube to prevent a false full reading when the
level could actually be low and result in engine
damage.

Air is also needed to keep
your engine cool. Dirt, dust &
debris build up restricts and
clogs
cooling
air
intake
screens
and
fins.
Clean
screens and fins at frequent
intervals. The engine blower
housing and shrouds should
be removed at least once
each season or more often
under dry, dusty conditions
for a thorough cleaning of
fins.
