MAINTENANCE

Replacing the air filter

If the engine seems to lack power or does not run smoothly this may be because the air filter is clogged. If run with a soiled air filter, carbon can build-up on the spark plugs and lead to malfunction.

For this reason, it is important to replace the air filter regularly (see “Maintenance schedule” on page 29 for the proper service interval).

WARNING!

Allow the exhaust system to cool before performing service. Risk for burns.
