CONTROLS

.

WARNING!

Gasoline is highly flammable. Observe caution and fill the tank outdoors

(see the safety rules).

WARNING!

Fill to bottom of filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.

When operating in temperatures below 32° F. (0° C.), use fresh, clean winter grade gasoline to help insure good cold weather starting.

Choke Control (All Models)

The choke control is used for cold starts in order to provide the engine with a richer fuel mixture.

For cold starts the throttle lever should be pushed all the way forward past “FAST” position to “CHOKE” position. Once engine has warmed pull throttle lever rearward to “FAST” (run) position.

Throttle Control (All Models)

The throttle control regulates the engine speed and thereby the rate of rotation of the blades. In order to increase or decrease the engine speed, the control is moved forward or backward respectively.

Avoid idling the engine for long periods, as there is a risk of fouling the spark plugs.

USE FULL THROTTLE WHEN MOWING, for best mower performance.

IMPORTANT INFORMATION

Experience indicates that alcohol blended fuels (called gasohol, ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage Instructions for additional information. Never use engine or carburetor cleaners in the fuel tank or permanent damage may occur.
