Starting the Engine Starting a Cold Engine OPERATION WARNING Engine exhaust contains poisonous carbon monoxide and can cause loss of consciousness resulting in severe injury or death. Never run an engine in an enclosed area. 1. Place the transmission in PARK and lock the parking brake. 2. Turn the fuel tank valve on. 3. Sit on the vehicle and pull the choke knob out until it stops (1). NOTE: The variable choke is fully 1 on when the knob is pulled completely out. The choke is off when the knob is pushed completely in. The choke can be adjusted gradually, depending on how much choke is needed for starting. Be sure the choke is off during operation, as excess fuel washing into the engine oil will increase wear on engine components. 4. Turn the engine stop switch to RUN. NOTE: Do not press the throttle while starting the engine. 5. Turn the ignition key past the ON position to engage the starter. Activate the starter for a maximum of five seconds, releasing the key when the vehicle starts. If the engine does not start, release the starter and wait five seconds. Activate the starter for another five seconds if necessary. Repeat this procedure until the engine starts. 6. If the engine slows or stops, position the choke knob half way in to allow proper engine warm-up. 7. Vary the engine RPM slightly with the throttle to aid in warm-up. When the engine idles smoothly, push the choke completely in. CAUTION Operating the vehicle immediately after starting could cause engine damage. Allow the engine to warm up for several minutes before operating the vehicle. 53
