- Move the choke lever to the 'Choke' position.
- Place the unit on a flat, stable surface. Hold the body of the product firmly with one hand.
- Pull the starter rope handle slowly until you feel resistance, then pull quickly and with force 1-4 times until the engine 'pops' or tries to start.
- Move the choke lever to the 'Run' position.
- Pull the starter rope handle again until the engine starts completely.
- Allow the engine to warm up for approximately 60 seconds before operating.
