Abstract
An electric pulse tool includes an electric motor drivingly connected to a flywheel, an output shaft drivingly connected to a drive element, and a compression spring. The electric pulse tool is operative to oscillate the flywheel between a first and a second direction. The flywheel is configured to drive the drive element in the first direction to provide a torque pulse on the output shaft in the first direction, whereby the drive element compress the compression spring. The drive element is configured to drive the flywheel in the second direction, when the compression spring is decompressed and forces the drive element to rotate in the second direction.
