Quick-Start Steps
- Charge before first use. Connect the included USB-C cable to the S1 Pro's charging port and plug into a USB-C wall adapter. The LED indicator will blink white slowly while charging and turn solid white when the battery is full. Do not use the screwdriver while the cable is connected — the motor will not run during charging.
- Open the pop-up case and select a bit. Press the latch to open the magnetic aluminum alloy case. The 16 S2 bits are organized in 5 categories — Phillips, flathead, Torx, hex, and pozidriv. Choose the bit that fits your screw head.
- Seat the bit into the magnetic chuck. Align the bit shank with the magnetic chuck opening and push until it clicks into place. Give it a gentle tug to confirm it is seated — a partially inserted bit will slip under load.
- Select your torque level. Press the torque-mode button to cycle through the three levels: 1.5 N·m for delicate electronics, 3 N·m for furniture and general assembly, 4.2 N·m for tougher fasteners. Start at the lowest level appropriate for your job and step up only if the screw doesn't seat fully.
- Set the rotation direction. Slide the forward/reverse switch to the desired direction before pressing the trigger. Forward drives screws in; reverse backs them out.
- Press the trigger and drive. Apply steady forward pressure on the screw while pressing the trigger. The S1 Pro runs at 220 RPM — a controlled pace that reduces cam-out on Phillips heads. Release the trigger as the screw seats to avoid stripping.
Torque and Speed Modes Explained
The S1 Pro has three electronic torque levels plus a manual mode:
- Level 1 — 1.5 N·m: Best for small machine screws, electronics repair, eyeglass frames, and any fastener where stripping the head or the material is a risk.
- Level 2 — 3 N·m: General-purpose setting. Suitable for furniture assembly (IKEA-style cam locks, dowels), light cabinetry, and most M3–M5 fasteners.
- Level 3 — 4.2 N·m: Harder fasteners and tighter-fitting threads. The clutch engages when the S1 Pro reaches torque, so it stops driving before over-torquing.
- Max hard torque — 6 N·m: The mechanical ceiling before the clutch releases. Driving a stuck or cross-threaded screw past this point requires switching to the manual mode handle.
- Manual torque — 8 N·m: The S1 Pro's chuck accepts manual turning for the highest-resistance situations, such as breaking a rust-seized screw free before switching back to electric drive.
Changing Bits
The magnetic chuck makes bit swaps tool-free and fast.
- Release the trigger and let the motor stop completely.
- Grip the current bit near the base and pull straight back — the magnet releases with a firm tug.
- Pick the new bit from the case and push it into the chuck until you feel the magnetic click.
- Tug gently to confirm engagement before driving.
All 16 included bits have the same shank diameter. Third-party bits must match the standard 1/4 in hex shank format to fit the S1 Pro chuck.
Charging and Battery Care
Charge via the USB-C port using a standard phone charger or any USB-C wall adapter. Read the LED indicators to track battery state:
- Charging: LED blinks white slowly.
- Fully charged: LED turns solid white.
- Low battery (below 20%): LED blinks red rapidly during use — finish the current job, then recharge before continuing.
- Cannot use while charging: The motor will not run when the USB-C cable is plugged in. Unplug, then operate.
The 2000mAh battery is rated for 1,300 screws per full charge under standard test conditions. Heavy-duty fasteners or sustained high-torque use will reduce that count; light electronics work will exceed it.
Safety Rules
- Always confirm the bit is fully seated before pressing the trigger — an unclipped bit can eject under torque.
- Start at the lowest torque level for any new fastener type; step up only if needed.
- Do not force a stuck screw past the max hard torque (6 N·m) with the electric mode. Switch to manual drive to break it free, then continue electrically.
- Keep the chuck and bit shanks clean and dry. Corrosion on the shank reduces the magnetic hold.
- Do not charge from a computer USB port or a 1A USB-A adapter if you need a full charge quickly — low-current sources will charge the 2000mAh cell very slowly.
- Store in the included magnetic case to protect the bits and prevent accidental activation.

A: The LED indicator turns solid white when charging is complete. While charging, it blinks white slowly.
Q: How do I change torque modes?
A: Press the torque-mode button to step through the three levels: 1.5, 3, and 4.2 N·m. The selected level is displayed via the indicator or labeled on the tool body — check the manual PDF for the exact indicator pattern on your unit.
Q: What bit shank size does the S1 Pro accept?
