Air Filter
The H4 engine that powers your Shindaiwa model is a hybrid 4-stroke engine. As a hybrid, the engine is lubricated by oil mixed
with the gasoline and air from the carburetor that moves through and around the internal parts of the engine in a similar way that
a 2-stroke engine is lubricated. Without the heavy duty 2-stage air filter equipped on all H4 engines, dust and dirt could also move
through the engine, decreasing engine life, increasing valve wear and the need for more frequent valve adjustments. To keep
your H4 engine strong and reliable, Shindaiwa recommends that you check and service the air filter as instructed in the 10-Hour
Maintenance section that follows.
NOTE:
Using non-standard replacement parts
could invalidate your Shindaiwa warranty.
