2-Cycle Tiller Transportation & Storage 2-CYCLE TILLER TRANSPORTATION Transporting your Tiller is easy. It’s light enough and easy to carry using the carrying handle as seen in Figure 1. Or, with it running, you can walk it by gently squeezing the throttle until it moves at a comfortable pace. Your tiller is easily transported in the back of a car or truck. Be sure to empty the fuel tank (This is crucial)! Then stow your tiller in the trunk of your car or truck.

Make sure to clear the choke button. 3. The air filter is the pad on the inside of the air-cleaner cover. Check whether it is soiled or moist. 4. If the air filter needs cleaning or no longer fits properly, remove it. Just lift an edge carefully and “peel” it out. (Picture 2) 5. Use a brush to remove debris from the pad. 6.

2-Cycle Tiller Maintenance HOW TO RESEAT THE FLANGE At some point, you may find that the tines won’t turn when you press the throttle. This may mean the engine isn’t sitting all the way down on the worm gear housing. Perhaps you’ve been using your Tiller for several years. Or perhaps you’ve removed the engine for use with our hedge trimmer attachment, then replaced it. In either case, the flange bolt may have come loose and lifted the engine up.
Troubleshooting Problem Cause Remedy 1. T ines don’t turn when throttle is depressed • Engine is not seated properly on the gear housing. • Re-install engine following the instructions on page 18 “How to reseat the flange”. 2. Engine fails to start • O/I switch is in “O” position. • No fuel in tank. • Fuel strainer clogged. • Fuel line clogged. • Spark plug shorted or fouled.
