2. Safety Information

Please read and understand all safety warnings and instructions before using this product. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.

• Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
• Avoid unintentional starting. Ensure the switch is in the off-position before connecting to battery pack, picking up or carrying the tool.
• Use the correct bit for the application. Forcing the tool may cause damage to the screw head or the tool itself.
• Do not over-tighten screws. Use appropriate torque settings.
• Do not expose the screwdriver to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not attempt to disassemble the battery or the screwdriver housing. Refer all servicing to qualified service personnel.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.

4. Product Overview

The HOTO 3.6V Smart Cordless Screwdriver features a sleek, minimalist design with user-friendly controls and intelligent functionalities.

• Screwdriver Body: Features a screwless, minimalist all-in-one design. The double-layered non-slip grip consists of a high-strength plastic inner layer and a soft TPE rubber outer layer, providing comfortable handling. The net weight is 250g.
• Control Buttons: User-friendly "screw-unscrew" buttons for easy operation.
• Torque Adjustment Knob: A four-staged rotary knob with a built-in intelligent chip allows for precise electronic torque control, similar to a zoom ring.
• Circular LED Shadowless Lamp: Illuminates the working area, automatically turning off 10 seconds after the button is released, making it suitable for dark corners.
• Type-C Charging Port: Conveniently located for charging with any compatible Type-C cable.
• Bit Set: Includes 12 pieces of 50mm long S2 alloy steel bits with a hardness up to 60HRC. These bits are resilient, durable, and coated with environmentally-friendly nickel for rust resistance.
• Storage Box: The frosted Al alloy storage box features an anodized sandblasting texture and an abrasion-resistant plastic base. It securely holds all 12 bits and has a soft rubber top handle for comfort and portability.

5. Setup

1. Initial Charging: Before first use, fully charge the screwdriver. Connect the provided Type-C charging cable to the charging port on the screwdriver and plug the other end into a suitable USB power adapter (not included). The charging time is less than 150 minutes.
2. Inserting Bits: Select the appropriate S2 steel bit for your task from the storage box. Insert the bit firmly into the screwdriver's chuck until it clicks into place. The bits are magnetic for secure attachment.
3. Selecting Torque: Rotate the mechanical knob at the front of the screwdriver to select the desired torque stage (OFF, Torque I, Torque II, Torque III).

6. Operating Instructions

1. Power On/Off: The "OFF" position on the torque adjustment knob acts as a safety lock, completely shutting down the device and preventing unintentional activation. To operate, rotate the knob to one of the torque settings.
2. Screwing/Unscrewing: Press the "screw" button (up arrow) to drive screws in, or the "unscrew" button (down arrow) to remove them. The circular LED lamp will automatically illuminate during operation and turn off 10 seconds after the button is released.
3. Torque Stages: The four-staged rotary knob allows you to adjust the torque to suit different applications:
   • Torque I (Modification-loving Geek): Low torque setting, ideal for delicate tasks such as assembling speaker sets or working with computer hardware. This setting helps prevent over-tightening and protects screws.
   • Torque II (At-home DIYer): Medium torque setting, perfect for general household DIY projects like assembling bookcases or flower shelves.
   • Torque III (Urban traveler): The highest torque setting, suitable for more demanding tasks such as assembling skateboards or bicycles.
4. Instant Stop Safety Feature: The built-in circuit board senses when the button is released and instantly stops the rotation. This prevents scratches or dents on your screws and protects your fingers from injury due to over-rotation.

7. Maintenance

• Cleaning: Wipe the screwdriver and bits with a clean, dry cloth after each use. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the screwdriver and all bits in the provided frosted Al alloy storage box in a dry place, away from direct sunlight and extreme temperatures.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the screwdriver regularly, even if not in use for extended periods. Do not attempt to replace the internal battery yourself.

8. Troubleshooting

• Screwdriver not turning on: Ensure the torque adjustment knob is not in the "OFF" position. Check if the battery is charged; if not, connect it to the charger.
• Bits slipping or not engaging: Ensure the correct bit size is used for the screw head. Make sure the bit is fully inserted into the chuck. Adjust the torque setting to a higher level if necessary.
• Short battery life: Ensure the screwdriver is fully charged before use. Extreme temperatures can affect battery performance; operate and store the tool within recommended temperature ranges.
• Unusual noise or vibration: Stop using the tool immediately and contact customer support.

10. User Tips

• The included bits are magnetic, which helps in holding screws securely during operation.
• For very tight screws, the screwdriver can be used for manual tightening after the electric mode has driven the screw most of the way.
• While versatile, this screwdriver may not be ideal for very delicate tasks like disassembling cell phones due to the size of the bits and potential for slight bit wobble.
