Engine Oil Replacement:
1. Replace engine oil after the first 20 hours of operation and
every 100 hours thereafter.
2. Oil may be drained more easily when it is warm after
operation.
3. When changing the engine oil, the old oil can be drained by
removing the oil filler cap, and unscrewing the engine oil
drain plug located at the base of the engine (Figure 17).
4. Remember to refill engine crankcase with the recommended
type of oil as listed in Table 4 (For more details, see separate
Honda Owner's Manual).

Air Filter
The air filter element should be regularly cleaned. A clogged air
cleaner can cause poor engine starting, lack of power and shorten
engine life substantially.
1. To clean or replace air filter loosen the wing nut on the air
filter housing (Figure 18), remove the cover and take out air
filter cartridge. If only cleaning of the air filter is desired blow
through the air filter cartridge from the inside, moving a jet of
dry compressed air up and down until all dust is removed.
Spark Plug
1. Remove and clean the spark plug (Figure 16).
2. Adjust the spark gap to 0.028 ~0.031 inch (0.6~0.7 mm). This
unit has electronic ignition, which requires no adjustments.
