CONTROLS 17 This operator’s manual describes the Husqvarna Zero T urn Rider . The rider is fitted with a four -stroke overhead valve engine. T ransmission from the engine is made via belt-driven hydraulic pumps. Using the left and right steering controls, the flow is r egulated and thereby the direction and speed.
CONTROLS 18 8050-003 Steering controls Steering Control Levers The machine’s speed and direction ar e continuously variable using the two steering controls. The steering controls can be moved forwar d or backward about a neutral position. Further more, ther e is a neutral position, which is locked if the steering controls ar e moved outward.
CONTROLS 19 Throttle Control The throttle contr ol regulates the engine speed and thereby the rate of r otation of the blades. In order to incr ease or decrease the engine speed, the control is moved forwar d or back respectively . Avoid idling the engine for long periods, as ther e is a risk of fouling the spark plugs.
CONTROLS 20 Choke Control The choke control is used for cold starts in order to provide the engine with a richer fuel mixtur e. For cold starts the throttle knob should be pushed forward all of the way . Refueling Read the safety instructions before r efueling.
CONTROLS 21 Fuel Shut Off V alve The fuel shut off valve is located in the fuel line under the seat. Tilt seat forward for access. The fuel valve is ON when the valve is parallel to the fuel line. Rotate the valve ¼ turn clockwise to tur n fuel OFF .
