MAINTENANCE SCHEDULE
CHANGING ENGINE OIL:
Change oil after the first 20 hours of operation. Thereafter it
should be changed every 00 hours.
1. Drain oil by removing the drain plug and the oil filler cap
while the engine is warm. (Fig. 6)
2. Reinstall the drain plug and fill the engine with oil until it
reaches the upper level on the oil filler cap.
NOTE: Use 4-stroke automotive detergent oil of API
service class SE or higher grade (SG, SH or SJ is
recommended). If contaminated or deteriorated oil is
used or the quantity of the engine oil is not sufficient,
the engine damage will result and its life will be greatly
shortened.
3. Dispose of used oil according to local zoning or
environmental regulations.
SERVICING THE AIR CLEANER:
Maintaining an air cleaner in proper condition is very
important. Dirt induced through improperly installed,
improperly serviced or inadequate elements damages and
wears out engines. Always keep the element clean.
. Unhook the cover and remove the cleaner element. (Fig.
7)
2. Urethane foam: Wash the element with fresh water.
Squeeze out the water then dry the element. (Do not
twist.)
CLEANING AND GAPPING SPARK PLUG:
If the plug is contaminated with carbon, remove the carbon
using a plug cleaner or wire brush. (Fig. 8)
