Getting Started Inspect the work area Remove stones, sticks, wires, and other objects that could be thrown by the blades or damage the unit. Use the correct extension cord Connect the tiller to a working 120V outlet using a heavy-duty outdoor extension cord. Use 14 AWG up to 50 ft or 12 AWG from 50–100 ft. Do not use an extension cord over 100 ft. Secure the cord Make a loop in the extension cord and place it through the handle opening and around the restraint hook. Then connect the extension cord to the appliance cord. Set the wheels Pull each wheel and move it to the desired position. Make sure both wheels are set to the same height and locked before use. Start the tiller Press and hold the safety lock button with your thumb, then squeeze the trigger switch. Once the tool is running, release the safety lock button. Till at a normal walking pace Move in straight, slightly overlapping rows. For full coverage, first till vertically, then work horizontally from left to right. Stop the tiller Release the trigger switch. Wait for the blades to stop completely before lifting, inspecting, transporting, or cleaning the machine. 🚫Do not use in rain, wet grass, damp soil, or standing water. The manual states that use in rain or wet conditions is prohibited. ⚠️ Do not force the tiller. Do not try to till too deeply or push the unit into extremely hard or resistant soil. This can overload the machine and reduce control. Operating Tips 1 Use on suitable soil The TJ603E is designed for small gardens and flower beds. It can loosen and turn soil, and mix coarse soil with fertilizer, peat, or compost. 2 Avoid extremely dry or wet soil Do not till extremely dry soil or very wet soil. Wet soil can stick to the blades and may cause slipping. 3 Keep a firm two-hand grip Hold both handles during use. Keep handles dry and apply light pressure to guide the machine. 4 Work across slopes When working on slopes, follow the safety symbol guidance and work across the slope, never up and down. Maintenance & Care 🚫Always switch OFF, unplug the tiller, and let the machine cool completely before inspecting, cleaning, or performing maintenance. Wait until the blades stop rotating before touching or moving the unit. 1 Clean after each use Use a dry cloth and brush to remove soil, dirt, foliage, and debris from the blades, drive shaft, tool surface, and vents. 2 Keep air vents clear Blocked air vents can cause overheating. Clean vents with a cloth and brush after every use. 3 Clean the underbody and blades safely Wear safety gloves and use a brush or wooden stick to remove soil from the blades. Never use bare hands near the working tool. 4 Lubricate blades Spray or rub biodegradable oil onto the blades after each use to help prolong blade life. 5 Check hardware Inspect nuts, bolts, screws, labels, guards, and safety features before and after use. Tighten loose hardware before operating. 6 Replace worn blades in pairs The machine uses 6 tilling blades. Always replace blade pairs together and install new blades in the same turning direction as the originals. 7 Store indoors Store the tiller in a dark, dry, frost-free, well-ventilated place out of children’s reach. Recommended storage temperature is 50°F to 86°F. ⚠️ Cleaning reminder: Do not spray the machine with water, especially pressurized water. Do not use chemical, alkaline, abrasive, or aggressive cleaners. Changing the Blades Power down safely Place the unit on a flat, stable surface. Turn the unit OFF and unplug it from the extension cord. Remove old blades Remove the 2 bolts and 2 nuts, then remove the steel blades from the drive shaft. Clean the drive shaft Clean the drive shaft with biodegradable oil before installing replacement blades. Install replacement blades Place the new blades on the drive shaft so the holes on the blade axles line up with the holes on the drive shaft. Secure the blades Insert the 2 bolts through the holes and secure them with the 2 nuts. Confirm the blades are installed in the correct turning direction.
