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 that you can move the machine by hand without the engine running. Note: Specifications and design are subject to change without notice. Width For normal operating position, pull up on the handle and then push it in until all 3 notches are inside the frame.
Operation • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.
