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 (A) from muffler (B), remove four screws that connect guard to muffler bracket (Figure 14).

Engine Air 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 an authorized Briggs & Stratton service dealer clean the cooling system (Figure 15) per recommended intervals (see Maintenance Schedule in the Maintenance section). Equally important is to keep top of engine free from debris. Also see Cleaning.

Check Valve Clearance

Regular valve clearance check and adjustment will improve performance and extend engine life. This procedure cannot be done without partial engine disassembly and the use of special tools. For this reason we recommend that you have an authorized Service Dealer check and adjust valve clearance at recommended intervals (see Maintenance Schedule in the Maintenance section).

Carburetor Adjustment

The carburetor on this engine is low emission. It is equipped with a non-adjustable idle mixture valve. Top speed has 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.
