Maintenance and Adjustments

IMPORTANT!

Maintenance, replacement or repair of emission control devices and systems may be performed by any repair establish- ment or individual; however, warranty repairs must be performed by a dealer or service center authorized by ECHO, Inc. . The use of parts that are not equivalent in performance and durability to authorized parts may impair the effectiveness of the emission control system and may have a bearing on the outcome of a warranty claim.

NOTE:

Using non-standard replacement parts could invalidate your Shindaiwa warranty.

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.

WARNING!

Accidental start-ups can cause severe injury! Before performing any maintenance on this equipment, stop the engine and disconnect the spark plug!
