WARNING SAFETY SUMMARY (continued)
Before doing any work on the electrical system,
disconnect the batteries at the Battery Disconnect.
The fuel needle is factory adjusted for the best heater
performance, using sophisticated exhaust gas analyz-
ing equipment. Do not drastically change the factory
setting in an attempt to speed starting. A lean fuel
mixture extends heater life and reduces maintenance.
Use insulated tools and take care to prevent contact
with high tension lead. High voltage is present
which could lead to injury.
