Remove stones, sticks, wires, roots, and other hard objects that could be thrown by the blades or damage the unit. 🌱 Use suitable soil conditions. Avoid tilling in rain, wet locations, very wet soil, or extremely dry/hard soil. Use light passes and do not force the tool. Extension Cord Guide ⚠️ Use an outdoor-rated extension cord only.

Starting + Tilling 1 Clear Area Remove rocks, sticks, and wires. › 2 Secure Cord Use cord lock and keep cord behind. › 3 Start Use safety switch and start switch. › 4 Cultivate Use slow, controlled passes. Position the tiller Place the TJ604E at the start of your garden row. Keep the power cord behind the unit and away from the blades. Start the tool Use the release safety switch and instant start switch to start the motor. Use controlled forward movement Guide the tiller slowly through the soil. Let the tines do the work instead of forcing the machine downward. Use overlapping rows For even soil prep, make straight passes with slight overlap between rows. Stop safely Release the switch, unplug the unit, and wait for the blades to stop completely before moving, checking, or cleaning the tiller. Tilling + Cultivating Tips 1 Break soil in stages For compacted soil, use multiple shallow passes instead of forcing the unit to till full depth immediately. 2 Avoid wet soil Wet soil can clump around the blades, reduce performance, and make the unit harder to control. 3 Do not force the tool If the tines slow or stop, reduce your pace, use a shallower pass, and inspect for debris after unplugging the unit. 4 Use for seedbed prep The TJ604E is helpful for aerating soil and preparing planting beds before seeding or transplanting. Care + Maintenance 🚫 Always unplug the tiller before maintenance. Wear protective gloves when working near the blades. Use a brush or wooden stick to remove debris; never use bare hands near the tines. 1 Clean after each use Remove soil, roots, weeds, and debris from the tines, housing, wheels, and handle area after operation. 2 Inspect the extension cord Check the cord before each use. Do not use a damaged extension cord. 3 Check hardware Make sure handle knobs, screws, wheels, guards, and visible hardware are secure before operation. 4 Keep vents clean Keep motor vents clear of dust, soil, grass, and debris to help prevent overheating. Storage 1 Unplug and clean Disconnect the tiller from power and clean off soil and debris before storage. 2 Fold the handle Collapse the foldable handle for compact storage when not in use. 3 Store indoors Store in a dry, secure indoor location out of reach of children and away from moisture.
