Spilled fuel is not only a fire hazard, it causes envi-
ronmental damage. Wipe up spills immediately.
Fuel can damage paint and plastic. Be careful
not to spill fuel when filling your fuel tank.
Damage caused by spilled fuel is not covered
under warranty.
FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating
of 86 or higher.
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 rapping 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 gaso-
line. If spark knock or pinging persists, see an
authorized servicing dealer.
Running the engine with persistent spark knock
or pinging can cause engine damage.
Running the engine with persistent spark knock
or pinging is considered misuse, and Hypro’s
Limited Warranty does not cover parts dam-
aged by misuse.
ENGINE OIL LEVEL CHECK
Check the engine oil level with the engine stopped
and in a level position.
1. Remove the filler cap/dipstick and wipe it clean.
2. Insert and remove the dipstick without screwing it
into the filler neck. Check the oil level shown on the
dipstick.
3. If the oil level is low, fill to the edge of the oil filler
hole with the recommended oil.
4. Screw in the filler cap/dipstick securely.
Running the engine with a low oil level can
cause engine damage.
The Low Oil Sensor (applicable engine types) will
automatically stop the engine before the oil level
falls below safe limit. However, to avoid the incon-
venience of an unexpected shutdown, always
check the engine oil level before startup.
ENGINE OIL CHANGE
Drain the used oil while the engine is warm. Warm
oil drains quickly and completely.
1. Place a suitable container below the engine to
catch the used oil, and then remove the filler
cap/dipstick and the drain plug.
2. Allow the used oil to drain completely, and then
reinstall the drain plug and tighten it securely.
Please dispose of used motor oil in a manner that
is compatible with the environment. We suggest
you take used oil in a sealed container to your local
recycling center or service station for reclamation.
Do not throw it in the trash, pour it on the ground, or
down a drain.
3. With the engine in a level position, fill to the outer
edge of the oil filler hole with the recommended oil.
