Installation Notes

Insert the bit fully into the chuck or bit holder before driving fasteners to prevent cam-out and bit slippage. Ensure the drill or impact driver is powered off and the battery is removed before changing bits. Match the correct bit size to the fastener head to avoid stripping the drive recess. Bits should be inspected for wear before use and replaced when rounding or deformation is visible on the drive tip.
