Engine Overspeed
This fault is indicated by fault code FC_6 and six blinks on the LED indicator. This feature protects devices connected to the transfer switch by shutting the generator down if the engine happens to run faster than the preset limit. The overspeed fault is detected as follows:
•If the generator output frequency is
•If the generator output frequency is greater than 70 Hz, the generator will shut down immediately.
This condition is caused by a failed engine governor. To remedy the problem, contact your installer or a Briggs & Stratton Authorized Dealer.
High Temperature
This fault is indicated by fault code FC_7 and seven blinks on the LED indicator. The contacts of the temperature switch (A) are normally open. The Oil Drain connector (B) is shown for reference. If the engine oil temperature exceeds approximately 148.9°C (300°F), the fault is detected and the engine shuts down.

Common causes for this condition include running the unit with all access doors removed, obstructed air inlet or exhaust port, low oil level, or debris in the engine cylinder cooling fins.
To resolve the problem, let the engine cool down and remove any accumulated debris and obstructions. Ensure that the access doors are installed whenever the unit is running.
Transfer Switch Fault
This fault is indicated by fault code FC_8 and eight blinks on the LED indicator (if transfer switch is equipped with fault detection). The most likely cause of this fault is a blown fuse in the transfer switch.
To remedy the problem, contact your installer or a Briggs & Stratton Authorized Dealer.
Generator Maintenance
The generator warranty does not cover items that have been subjected to operator abuse or neglect. To receive full value from the warranty, the operator must maintain the system as instructed in the engine operator’s manual.
All adjustments should be made at least once each season. Follow the requirements in the engine operator’s manual.
Generator maintenance consists of keeping the unit clean. Operate the unit in an environment where it will not be exposed to excessive dust, dirt, moisture or any corrosive vapors. Cooling air louvers on the enclosure must not become clogged with snow, leaves, or any other foreign material.
Check the cleanliness of the unit frequently and clean when dust, dirt, oil, moisture or other foreign substances are visible on its exterior/interior surface.
NOTE: DO NOT use direct spray from a garden hose to clean generator. Water can enter the engine and generator and cause problems.
Engine Oil
The system is filled with synthetic oil
NOTE: The use of synthetic oil does not alter the required oil change intervals described in the engine operator’s manual.
Changing Engine Oil
•Place the oil drain tube into an approved container.
•Push in and rotate the oil drain fitting 1/4 turn counterclockwise. Slowly pull outward until oil starts draining. DO NOT pull the oil drain fitting off the engine.
•When the oil has drained, push the oil drain fitting in and rotate 1/4 turn clockwise until it locks in place.
•Slide the oil drain tube up into the clamp on the generator.
