Maintenance
⚠WARNING
All the components used to build this engine must remain in place for proper operation.
Use only original equipment replacement parts. Other parts may not perform as well,
may damage the unit, and may result in injury.
In addition, use of other parts may void your warranty. We recommend that you use an authorized
service center for all maintenance and service of the engine and engine parts.
Before performing adjustments or repairs
Disconnect the spark plug wire and keep it away from the spark plug.
• Use only correct tools.
• Do not tamper with governor spring, links or other parts to increase engine speed.
• Replacement parts must be the same and installed in the same position as the original parts.
• Do not strike the flywheel with a hammer or hard object because the flywheel may later shatter
during operation.
When Testing for Spark
Use an approved spark plug tester.
