How to use

Fit an appropriate standard bit for the screw or fastener and secure it in the chuck or bit holder. Select the required torque or operating mode according to the task and material. Position the driver head squarely on the fastener and apply steady pressure while engaging the trigger to start rotation; the impact mechanism will operate as needed under load. Release the trigger once fastening is complete and inspect the joint for correct engagement. Follow standard safety practices such as wearing eye protection and disconnecting power or removing batteries before changing bits.

Usage recommendations

For consistent results, pre-select torque settings for softer materials and use higher torque or impact mode for harder materials and longer fasteners. Use bits in good condition to prevent cam-out and ensure accurate torque transmission. Store the tool dry and check bit retention regularly to maintain safe operation.
