surface and stopped.
b. Remove the filler cap/dipstick and check the
oil level shown on the dipstick.
c. If the oil level is low, fill to the edge of the oil
filler hole with the recommended oil.
Oil capacity: 0.4L
SAE 10W-30 is recommended for general
use. Other viscosities shown in the chart may
be used when the average temperature in
your area is with the recommended range.
CAUTIONS! Use not depurative lubrication or 2-cycle lubrication can cause
engine damage.
3. Check air cleaner
NOTICE! Operating the engine without an air filter, or with a damaged air
filter, will allow dirt to enter the engine, causing rapid engine wear. This type
of damage is not covered by the Distributor’s Limited Warranty.
4. Check fuel
These engines are certified to operate on unleaded gasoline. Unleaded
gasoline produces fewer engine and spark plug deposits and extends
exhaust system life. Never use stale or contaminated gasoline or an oil
/gasoline mixture. Avoid getting dirt or water in the fuel tank. Occasionally
you may hear a light “spark knock” or “pinging” (metallic raping noise) while
operating under heavy loads. This is no cause for concern. If spark knock
or pinging occurs at a steady engine speed, under normal load, change
brands of gasoline. If spark knock or pinging persists, see an authorized
you’re servicing dealer.
DANGER!
A. Gasoline is highly flammable and explosive.
B. Refuel in a well-ventilated area before starting the engine. If the
