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 carbure-
tor 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.
