Briggs & Stratton Liquid-Cooled Home Generator System Generator Maintenance, Engine Maintenance

High Temperature (FC_7)

This fault is indicated by fault code FC_7 and seven blinks on the LED indicator. The contacts of the coolant temperature switch are normally open. If the engine coolant temperature exceeds approximately 115.5°C (240°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 or coolant level, or debris in the engine compartment or radiator.

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 (FC_8)

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 Maintenance

An engine manual was packaged with this system. Please refer there for all engine-related maintenance topics. However, proper engine cooling and lubrication are so important we give them special mention here.

Engine Oil

The system is filled with the recommended non-synthetic oil (API SL 10W-30W). This allows for system operation in a wide range of temperature and climate conditions.

NOTE: Refer to the engine operator’s manual for recommended oil change intervals.

Shown here is the oil drain location (B) and the oil filter (A).

Changing Engine Oil

CAUTION

Avoid prolonged or repeated skin contact with used motor oil.

•Used motor oil has been shown to cause skin cancer in certain laboratory animals.

•Thoroughly wash exposed areas with soap and water.

KEEP OUT OF REACH OF CHILDREN. DON’T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.

1.Disconnect the negative battery terminal from battery.

2.Change oil while the engine is still warm from running, as described in the engine operator’s manual.

notice

Any attempt to crank or start the engine before it has been properly serviced with the recommended oil will result in equipment failure.

•Refer to Maintenance and engine manual for oil fill information.

•Damage to equipment resulting from failure to follow this instruction will void engine and generator warranty.

To fill your engine with oil:

Follow the oil grade recommendation and oil fill instructions given in the engine operator’s manual.

To make the task of adding oil more convenient, we recommend use of a funnel attached to a length of tubing long enough to reach from the Coolant Fill door to the oil fill opening on the engine valve cover.
