Operating Instructions

Powering On/Off and Speed Control

1. Power On: Press the accelerator switch to start the tool. The speed is variable depending on the pressure applied to the switch.
2. Power Off: Release the accelerator switch. The electronic quick brake will stop the chuck rotation.
3. Lock-on Function: For continuous operation, press the accelerator switch and then engage the lock-on button (if present, typically on the side of the switch). To release, press the accelerator switch again.

Selecting Rotation Direction (Forward/Reverse)

A forward/reverse switch is located above the accelerator switch.

• Push the switch to the left for forward rotation (drilling/driving).
• Push the switch to the right for reverse rotation (removing screws/bits).
• Position the switch in the center for the lock-off position, preventing accidental starting.

Selecting Torque and Speed Settings

The tool features a torque collar and a 4-speed gearbox.

1. Torque Setting: Rotate the torque collar to select the desired torque level (1-11) for screwdriving. The drill symbol indicates drill mode, which bypasses the clutch for maximum power.
2. Speed Setting: Use the gear selector switch (typically on top of the tool) to choose between the four speed ranges (1, 2, 3, 4). Lower speeds are for higher torque applications (e.g., driving large screws), while higher speeds are for drilling.
