Whether renting, buying or borrowing a rototiller, you must know how to start it in order to operate the tiller. Most gas-powered tillers, whether rear or front tine, follow the same basic starting instructions. Learn how to start your rototiller properly the first time to avoid flooding it or causing potentially costly mechanical problems.
Switch the "on/off" or "start/stop" button to "on" or "start."
Find the choke button or level. Pull it out or switch it to the closed position to close the choke.
Press the purge bulb, if provided, located on the engine, to send fuel through the fuel return line. Press it until you see fuel flowing through the line and then immediately stop pressing. If a purge button is not located on the tiller, simply turn the throttle lever toward the "fast" position before starting.
Pull the starter cord back towards you about 12 to 18 inches until the engine starts. When the engine starts, it may only sound like a sputter as it will not run on choke.
Push the choke button back in to open the choke.
Pull the starter cord back towards you again. The engine will now run, but let it warm up for three minutes before using the tiller.
