ENGINE CARE
If major engine service or repair is required, contact
an authorized engine service center. The manufac-
turer of these engines has established an excellent
world-wide engine service organization. Engine ser-
vice is very likely available from a nearby authorized
dealer or distributor. Check the yellow pages of your
local telephone directory under “Engines-Gasoline”
for the closest engine repair center or ask the dealer
from whom you purchased the power plant.
1.
Change the oil
after the fi rst 20 hours of opera-
tion and yearly or 100 hours thereafter under normal
operating conditions. Change engine oil every 50
hours of operation if the engine is operated under
heavy load, or in high ambient temperatures.
a. Start the engine and warm it up, stop the engine
and remove the spark plug wire to prevent it
from accidently being started.
b. Remove oil drain bolt at base of the engine
and drain the oil into an approved container.
c. Replace oil drain bolt making sure the sealing
washer is in place..
d. With the engine in a level position, fi ll with new
oil. Refer to the table on page 5 for the proper
grade of oil.
NOTE: This engine requires 38 to 39 ounces of oil
if it is completely drained. Use caution when refi lling
the engine as some residual oil may have remained
in the engine. Always use the dipstick when fi lling the
engine with oil to prevent overfi lling.
e. Replace
fi ller plug.
f
Start the engine up and warm it up.
h. After warming up the engine, recheck the oil
level and refi ll as necessary to bring it to the
proper
level.
2.
Checking the Oil Level
: The oil level must al-
ways be checked before the engine is started. Take
care to remove any dirt or debris from around the
oil fi ll plug before removing. Be sure the oil level is
maintained. Fill to the “
FULL
” mark on the dipstick.
3.
Dual Element Air Filter
: Clean and/or replace
foam pre-cleaner and air fi lter annually or every 100
hours. Service more often under dusty conditions.
WARNING: EQUIPMENT DAMAGE
Never start or run the engine with the air fi lter re-
moved
a. Remove the wing nut from the air cleaner cover
and remove cover
b. Remove the wing nut from the air fi lter, and
remove
the
fi lter.
d. Remove the foam fi lter element from the paper
fi lter element.
e, Inspect
both
fi lter elements, and replace them
if they are damaged. Always replace the paper
fi lter element at the scheduled interval.
See page 11.
f.
To loosen debris, gently tap the air fi lter on a
hard surface. If the air fi lter is excessively dirty
replace with a new fi lter. You can use pres-
surized air (not to exceed 30 psi.) to clean the
fi lter. Always blow the compressed air from
inside to the outside.
g. Wash the foam fi lter element in liquid detergent
and water. Then allow it to thoroughly air dry.
Dip the foam fi lter element in clean engine oil
and squeeze out all the excess oil. The engine
will smoke when started if too much oil is left in
the
foam.
h. Clean the dirt from the inside of the air cleaner
body and cover. Be careful to prevent dirt from
entering the air duct that leads to the carburetor.
Reinstall the air fi lter in housing making sure
the gasket is in place beneath the fi lter element.
Tighten the wing nut securely.
