Fuel-Shutoff Valve Blade-Control Lock The fuel-shutoff valve (Figure 5) is located on the engine and is used to shut off the fuel when the machine will not be used for a few days, during transport to and from the jobsite, and when parked inside a building. The blade-control lock (Figure 6) is located on the left side of the handle, next to the blade-control bail. Moving the blade-control lock into the full forward position allows the blade-control bail to be squeezed against the handle.
Hydrostatic-Drive Bypass Lever Specifications The hydrostatic-drive bypass lever (Figure 8) releases the hydrostatic-drive system so you can move the machine by hand, without the engine running.

Adding Fuel Operation Capacity: 5.6 L (1.48 US gallons) Note: Determine the left and right sides of the Recommended Fuel: machine from the normal operating position. • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). Before Operation Safety • Ethanol: Gasoline with up to 10% ethanol General Safety (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable.
DANGER DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. In certain conditions during fueling, static electricity can be released, causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling.
