This cordless impact wrench is designed for driving and loosening screws and bolts. Always ensure the battery is charged and the correct bit is inserted before use. The tool features a 1/4" internal hexagon tool holder, a user interface for speed and mode selection, and optional Bluetooth connectivity via the GCY 42 module.
Assembly
Battery: Slide the charged battery into the holder until it clicks. To remove, press the release button and pull the battery out. Do not use force.
Tool Change: Insert the bit into the tool holder (1). If insertion is difficult, pull the locking sleeve (2) forward and then push the bit in until it stops. Ensure the bit is securely locked.
Operation
Direction: Use the rotational direction switch (3) to change between clockwise (right) and counter-clockwise (left) rotation. This cannot be changed while the On/Off switch (9) is pressed.
Speed/Impact Rate: Regulate the speed and impact rate by varying the pressure on the On/Off switch (9). Light pressure results in low speed; increasing pressure increases the speed.
User Interface: Use the interface (8) to preselect speed settings (19) and working modes (17). The status indicator (15) shows the tool's current state.
Maintenance
Clean the air vents regularly to prevent dust accumulation, which can cause electrical hazards. Periodically clean the tool holder (1) and locking sleeve (2). Always remove the battery before performing any maintenance or transport.
