WARNING
Operating the engine without the air filter element in place could be
hazardous.
If the air filter element did not filter dirt, severe engine damage would
occur if the dirt entered the running engine.
Never run the engine without the air filter element in place.
CAUTION
!
Failing to inspect the air filter element frequently if the vehicle is used in
dusty, wet, or muddy conditions could damage your Go-kart.
The air filter element could become clogged under these conditions, and
engine damage may result.
Always check the air filter element after riding in severe conditions.
Clean or replace the elements as necessary. If water gets in the air filter
case, immediately clean the element and the inside of the case.
CAUTION
!
A torn air filter could damage your Go-kart.
Dirt and dust may get inside of the engine if the element is torn.
Examine carefully the element for tears before and after cleaning it.
Replace the element with a new one if it is torn.
CAUTION
!
Failing to position the air cleaner element properly could damage your
Go-kart.
Air will bypass the air cleaner element if the element is not positioned
properly. This will cause the engine parts to wear more rapidly.
Be sure to position the air cleaner element properly.
