a detent at the "idle" position, continuing rearward past this detent will shut off the engine.

B&S 8.5 hp Engines:

For the B&S 8.5 hp engine the choke control is located on the left side of the engine (from operator's position). Pull the choke lever outward and to the rear (counter-clockwise from top).

Once the engine has started, move the choke control to the off position and move the throttle control to about medium throttle position to allow engine to warm-up before going to full throttle.

To stop the engine, move the throttle control lever to the full rearward position.

4.1.7Transmission Shift Lever:

Located under the control console and behind the

fuel tank. It shifts the 5-speed transmission into five forward gears, neutral and reverse. Shift transmission only when drive levers are in the neutral position. Shifting without drive levers in neutral may cause damage to the transmission.

NOTE: Reverse is "reverse assist" only, meaning when the transmission is in reverse, the operator has to pull the unit backward to "assist" with the movement of the unit.

4.1.8Fuel Shut-Off Valve:

Installed on the fuel line midway between the fuel tank and the engine. The fuel shut off valve shuts off the flow of fuel when the machine will not be used for a few days, when parking inside a building, and during transport to and from the job. Rotate the valve 1/4 turn clockwise to shut off fuel. Rotate the valve 1/4 turn counter-clockwise to turn on fuel.

4.2PRE-START

4.2.1Refer to the Maintenance Section 5.1 and perform all

of the necessary inspection and maintenance steps.

•Fuel is highly flammable. Add fuel before starting the engine. Refuel outdoors or in a well ventilated area.

•DO NOT smoke when refueling or operating the equipment. Never remove the cap of the gas tank while engine is hot or when engine is running.

4.2.2Fill fuel tank. For best results, use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher. Regular grade leaded gasoline may also be used; however, combustion chamber and cylinder head will require more frequent service. See Engine Owner's Manual.

Do not add oil to gasoline.

Do not overfill fuel tank. Never fill the fuel tank so that the fuel level rises above a level that is ½” below the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage.
