certified and require the following maintenance.
■
The fuel cap includes a rubber gasket that can become worn over
time. The gasket is important for keeping the fuel system sealed,
and must be replaced if damaged. Check the gasket once a year.
Use only a gasket that provides a vapor-proof seal. Use only
manufacturer-approved replacement parts.

The EPA-approved fuel lines are made from rubber that can degrade
over time. The fuel lines are vital for proper operation, and must be
replaced if damaged. Check the fuel lines once a year. Use only EPA-
approved fuel lines.

When servicing an XAF generator, shut off all fuel lines and
eliminate all possible outside sources of ignition.
