Briggs & Stratton 30236 Clean Cooling System, Carburetor Adjustment, Maintenance

MAINTENANCE

WARNING

Running engines produce heat.Temperature of muffler and nearby areas can reach or exceed 150°F (65°C).

Severe burns can occur on contact.

Exhaust heat/gases can ignite combustibles, structures or damage fuel tank causing a fire.

•DO NOT touch hot surfaces and avoid hot exhaust gases.

•Allow equipment to cool before touching.

•Keep at least 5 ft. (152 cm) clearance on all sides of generator including overhead.

•Code of Federal Regulation (CFR) Title 36 Parks, Forests, and Public Property require equipment powered by an internal combustion engine to have a spark arrester, maintained in effective working order, complying to USDA Forest service standard 5100-1C or later revision. In the State of California a spark arrester is required under section 4442 of the California Public resources code. Other states may have similar laws.

Clean and inspect the spark arrester as follows:

1.To remove muffler heat shield from muffler, remove four screws that connect guard to muffler bracket (Figure 14).

Clean Cooling System

Over time debris may accumulate in cylinder cooling fins and cannot be observed without partial engine disassembly. For this reason, we recommend you have a authorized service dealer clean the cooling system (Figure 15) per recommended intervals (see “Maintenance Schedule” on page 15). Equally important is to keep top of engine free from debris. See “Generator Cleaning”.

2.Remove four screws that attach spark arrester screen.

3.Inspect screen and replace if torn, perforated or otherwise damaged. DO NOT use a defective screen. If screen is not damaged, clean it with commercial solvent.

4.Reattach screen and muffler guard.

Carburetor Adjustment

The carburetor on this engine is low emission. It is equipped with a non-adjustable idle mixture valve and governed idle, if equipped. Governed idle and top speed have been set at the factory. If adjustment is required, see an authorized service dealer.

CAUTION

Excessively high operating speeds increase risk of injury and damage to generator.

Excessively low speeds impose a heavy load.

•DO NOT tamper with governed speed. Generator supplies correct rated frequency and voltage when running at governed speed.

•DO NOT modify generator in any way.
