ENGINE CARE
MAINTENANCE SCHEDULE
If major engine service or repair is required, contact an
authorized engine service center. The manufacturer of
these engines has established an excellent world-wide
engine service organization. Engine service is very likely
available from a nearby authorized dealer or distributor.
CHECKING THE OIL LEVEL
The oil level must always be checked before the engine is
started. Refer to he lubrication section of this manual for
instructions on checking the oil level. Take care to remove
any dirt or debris from around the oil plug before removing.
Be sure the oil level is maintained.
CHANGING THE OIL
Refer to the Maintenance Schedule Chart for required oil
change intervals.
Outdoor temperatures determine the proper oil viscosity for
the engines. Winco recommends our 5W-30 fully synthetic
oil to give you excellent protection in cold temperatures
while maintaining excellent performance in warmer
weather.
A. Start the engine and warm it up, stop the engine and
remove the spark plug wire to prevent it from
accidentally being started.
B. Remove the oil drain bolt at base of the engine and
drain the oil into an approved container.
C. Replace the oil drain bolt making sure the sealing
washer is in place.
D. With the engine in a level position, fill with new oil.
Refer to the table in the Oil Recommendation section in
this
manual.
NOTE: This engine requires 38.4 ounces (1.2 qt) of oil if
completely drained. Use caution when refilling the engine
as some residual oil may have remained in the engine.
Always use the dipstick when filling the engine with oil to
prevent overfilling.
E. Replace filler plug.
F. Start engine up and warm it up.
G. After warming up the engine, recheck the oil level and
refill as necessary to bring it to the proper level.
DUAL ELEMENT AIR FILTER
Clean and/or replace the foam pre-cleaner and the air filter
annually or every 100 hours. Service more often under
dusty conditions.
WARNING: EQUIPMENT DAMAGE
Never start or run the engine with the air filter
removed.
A. Remove the wing nut from the air cleaner cover and
remove
cover.
B. Remove the wing nut from the air filter and remove
the
filter.
C. Remove the foam filter elements from the paper filter
element.
D. Inspect both filter elements and replace them if
damaged. Always replace the paper filter element at
the scheduled interval.
E. To loosen debris, gently tap the air filter on a hard
surface. If the air filter is excessively dirty replace with a
new filter. You can use pressurized air (not to exceed
30 psi) to clean the filter. Always blow the compressed
air from inside to the outside.
F. Wash the foam filter element in liquid detergent and
water. Then allow it to thoroughly air dry. Dip the foam
filter element in clean engine oil and squeeze out all
the excess before reinstalling it.
The engine will smoke when started if too much oil is
left in the foam.
