Operating Instructions29Engine ThrottleThe throttle control lever (red knob) is located on theleft side of the seat and is used to control enginespeed. Moving the lever forward toward the FASTposition increases engine speed; moving it back-ward toward the IDLE position decreases enginespeed.ThrottleThrottle LocationBody LatchThe front portion of the tractor body hinges forwardfor maintenance access and is latched down in theOPERATING position. To raise the body, first tilt theutility bed back, then pull back and up on body latchand lift the body from behind the seat.BodyLatchBody LatchForward Speed Control (FSC)Forward Speed Control (FSC) has two functions:One is to set forward travel speed, and the other isto establish the NEUTRAL-PARK position. Whenthe FSC lever is moved into the FORWARD position, a friction lock holds any forward speed settingfrom 0 to 10 mph (0 to 16 km/h). The ground speedis proportional to the lever position; the further thelever is advanced forward, the faster the tractormoves. It is not necessary to hold the FSC in position since the friction lock maintains the selectedlever position. Pulling back on the steering leversoverrides the FSC setting and slows or stops forward travel. Releasing the steering levers allowsthe tractor to resume forward travel at the speed setby the FSC lever. To stop and park the machine, theFSC lever is moved backward to the NEUTRAL-PARK position.Fuel Pump PrimingThe Kohler diesel engine is equipped with a mechanical fuel pump and in certain situations (runningout of fuel, changing the fuel filter, or other fuel system maintenance) the fuel system may need to beprimed by removing air trapped in the system. Fuelpump priming should be used if the engine does notstart after a couple of 10 second cranking attempts.NOTE: DO NOT use prolonged cranking to primethe fuel system as this may damage the starter andshorten battery life.Use the following procedure to prime the fuel pumpand purge air out of the fuel system:1. Loosen the bolt on the fuel injection pump returnhose where it attaches to the fuel filter housingas shown.FuelFilterFuel Injection PumpReturn HoseLoosen Bolt to BleedAir From Fuel SystemAir Bleed Bolt Location2. Turn ignition key to ON to open the electric fuelshutoff valve (do not crank or run engine).3. Repeatedly stroke the Fuel Pump Primer leveruntil fuel is flowing out of the return hose fitting.(continued on next page)
