Who Is This Tiller Best For? 🏡 Homeowners maintaining small to medium garden beds 🌱 Anyone preparing soil for planting, seeding, or landscaping 🪴 Gardeners mixing compost, fertilizer, or peat into soil 💪 Users looking for a lightweight alternative to heavy gas-powered tillers ⚠️This product is designed for private domestic use only — not commercial, trade, or rental applications. It is best suited for small gardens and flower beds, not large-scale farming or extremely hard, dry, or wet soil. Assembly 🚫Do NOT connect to power until assembly is fully complete. Failure to comply may result in accidental starting and serious personal injury. Unpack and inspect Remove all items from the carton. Confirm every part is present and undamaged. If anything is missing or broken, do NOT return to the store — call us at 1-866-225-9723. Attach the middle handle bars (Position A) Remove bolts from the knobs and set aside. Slide the two middle handle bars into the lower handle and secure with the first set of knobs and bolts (Position A). Tighten fully on both sides. Connect the upper handle (Position B) Slide the upper handle onto the middle handle and secure with the second set of knobs and bolts (Position B). Tighten fully on both sides. All four knobs must be fully tightened before use. Route and clip the cord Secure the appliance cord through the two cable clips along the handle to keep it tidy and out of the way of the tines. Connect the extension cord Use an approved outdoor-rated extension cord. Loop the cord through the hole in the handle and around the extension cord restraint hook before connecting, to prevent accidental disconnection during use. ⚠️Confirm the voltage on the rating label matches your power supply (120V / 60 Hz) before plugging in. Getting Started Before First Use Assemble the handle completely and confirm all knobs are tightened Inspect the unit and extension cord for any shipping damage Clear the work area of rocks, sticks, wire, and other foreign objects Confirm the area is dry — never operate in rain or wet conditions Adjusting Wheel Depth Before tilling, pull the lock pin on the rear wheel bracket and move to one of 4 available positions. A higher wheel position = deeper tine penetration. Always confirm the wheels are securely locked before operating. Turning On Connect to power Plug into a 120V outlet using your outdoor extension cord. Loop it through the restraint hook first. Press the Safety Lock Button Press and hold the safety lock button (top of right handle) with your thumb. Squeeze the Trigger Switch With the lock button held, squeeze the trigger switch with your fingers. Once running, you may release the lock button. Turning Off Simply release the trigger switch. The tines will continue rotating for a few seconds — do not touch them until they have fully stopped. ⚠️The motor housing stays hot for a short time after shutoff. Allow it to cool completely before touching or storing near combustible materials. Tilling Tips 📋 Recommended Tilling Pattern (for best coverage) 1 Move vertically in straight rows — up and down → 2 Move horizontally left to right in overlapping rows → 3 Result: even, fully-tilled soil with no missed spots Walk at a normal, steady pace — do not rush or force the machine Till in slightly overlapping rows for full coverage Apply light downward pressure on the handles when turning to lift the tines Do not till extremely wet or extremely dry soil — both can damage the unit Do not try to till too deeply or force the tines into very hard or resistant soil If the unit strikes a foreign object, stop immediately, unplug, and inspect before continuing If excessive vibration occurs at any time, stop the machine and inspect for damage Keep the air vents clear of debris at all times to prevent overheating Care & Maintenance 🚫Always switch off and unplug before cleaning, inspecting, or performing any maintenance. Wait for the tines to fully stop rotating. After Every Use Clean the tines and drive shaft Use a dry brush or cloth to remove all soil, dirt, and debris from the tines, drive shaft, and air vents. Lubricate the tines Spray or rub biodegradable oil onto the tines to prevent rust and extend service life. Wipe the handles Clean soiled grips with a damp cloth. Keep handles dry, clean, and free of oil or grease. Periodic Checks Inspect and tighten all nuts, bolts, and handle knobs Confirm tines rotate freely without debris buildup Inspect the extension cord for wear or damage — replace immediately if found Verify all safety labels and guards are in place and readable Changing the Tines The unit comes with 6 steel tines replaceable in pairs (3 per side). Always replace both pairs at the same time to avoid imbalance. Power off and unplug Place the unit on a flat, stable surface. Remove the old tines Remove the 2 bolts and 2 nuts, then slide the steel blade tines off the drive shaft. Clean the drive shaft Spray or rub biodegradable oil onto the drive shaft. Install new tines Align the new tines on the drive shaft so all holes line up. Insert the 2 bolts through the holes and secure with the 2 nuts. ⚠️Install tines in the correct rotation direction. Note how the old tines were positioned before removing them, and install the new ones the same way. Storage Disconnect the extension cord before storing Store in a dry, frost-free, dark, and well-ventilated indoor location Ideal storage temperature: 50°F – 86°F (10°C – 30°C) Keep out of reach of children Use the original packaging or cover with a protective cloth Power Cord Damage If the appliance power cord is damaged, it must be replaced to avoid safety hazards.

Yes — tines continue rotating for a few seconds after power-off due to motor momentum. This is normal and expected behavior. What To Do Do not touch the tines until they have completely stopped If spinning persists abnormally long, contact support 🟡 Motor Overheating Possible Causes Air vents blocked with debris Forcing tines into extremely hard soil Extended continuous use without breaks Solutions Stop and allow the motor to cool completely Clean air vents with a soft brush Take regular breaks during extended use Avoid forcing the tool into very compact soil 🟡 Extension Cord Disconnects Possible Causes Cord not secured to restraint hook Cord being pulled or stepped on Solutions Always loop the extension cord through the restraint hook before connecting Keep the cord clear of the work path Optionally, tie both cords together as shown in the operator's manual (Table 1) 💡This product does not contain any parts that can be repaired by the consumer (except tine replacement). For all other repairs, contact an authorized Sun Joe® dealer or call 1-866-225-9723. Frequently Asked Questions Does the TJ605E come with an extension cord? No — an extension cord is not included. You will need an outdoor-rated, polarized extension cord: 14 AWG for up to 25 ft, or 12 AWG for up to 50 ft. Sun Joe® recommends the Power Joe® PJEXT50-B 14-gauge 50-ft model. Order at shopjoe.com or call 1-866-225-9723. Can this tiller handle hard or compact soil? The TJ605E can handle typical garden soil effectively. For very compact soil, it's best to make multiple lighter passes rather than forcing the unit to full depth in one go. Do not force the tines into extremely hard, dry, or rocky soil — this can cause damage and excessive wear. If the machine is struggling, reduce the depth setting and work incrementally. Can I use this tiller in wet or rainy conditions? No — operating the TJ605E in rain or wet conditions is strictly prohibited per the operator's manual. Wet soil also tends to stick to the tines and prevent proper rotation, and standing water creates a serious electric shock hazard. Always operate in dry conditions only. Does this require gas or oil? No. The TJ605E is fully electric — it operates on a standard 120V household outlet via a heavy-duty outdoor extension cord. There is no gas, oil, carburetor, spark plug, or engine to maintain. Simply plug in and go. Is this suitable for large areas? The TJ605E is designed for small gardens and flower beds, not large-scale farming or extensive acreage. It is ideal for residential garden plots, vegetable beds, and flower borders. For large commercial areas, a heavier-duty gas-powered unit may be more appropriate. How do I start the tiller? Press and hold the Safety Lock Button on the right handle with your thumb, then squeeze the Trigger Switch with your fingers. Once running, you may release the safety lock button. To stop, release the trigger. The tines will continue spinning for a few seconds after — do not touch them until they fully stop. The tines keep spinning after I turn it off — is that normal? Yes, this is completely normal. Residual motor momentum will keep the tines rotating for a few seconds after the trigger is released. Do not touch the tines until they have completely stopped. This is standard behavior and not a defect. How do I adjust the wheel depth? Pull the lock pin on the rear wheel bracket and move the wheel to one of 4 positions. A higher wheel position means the tines dig deeper. Always confirm the wheels are clicked into position and fully locked before operating. Never use the product with the wheels in an unlocked position. Can it remove weeds? Yes. The rotating tines will uproot and chop weeds as they turn the soil, making it an effective weed control tool for garden beds. For best results, till the area before weeds go to seed to prevent regrowth. Are the tines replaceable? Yes. The 6 steel tines are replaceable using the TJ605E-2 Replacement Blade Set. Tines must always be replaced in pairs (both pairs at once) to maintain proper balance. Note that tines are considered wearing parts and are not covered under the standard warranty. Order at shopjoe.com or by calling 1-866-225-9723. My tiller vibrates excessively — what should I do? Excessive vibration is a signal of potential damage. Stop the machine immediately, unplug it, and inspect for: bent or missing tines, loose bolts, debris on the drive shaft, or foreign objects in the work area. If you cannot identify or resolve the issue, contact our team at 1-866-225-9723 before resuming use. Can I use any extension cord? No. You must use an outdoor-rated, polarized extension cord of an approved type: SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A, or SJTOW-A. Use 14 AWG for up to 25 ft, or 12 AWG for 25–50 ft. Never exceed 50 ft. An undersized cord causes voltage drop, overheating, and motor damage. Can I repair this product myself? The only user-serviceable tasks are tine replacement and cleaning. The motor, gearbox, and power cord must be serviced by a qualified technician at an authorized Sun Joe® dealer. This is a double-insulated appliance — never attempt to open the motor housing or add a grounding connection. Call 1-866-225-9723 for service referrals. How do I register my product?
