Abstract

A hand-held power tool may include a rotatable work tool with a center, a circumference and a direction of rotation. The power tool may further include a blade guard arrangement arranged to shield a variable part of the rotatable work tool which may include a blade guard and a swiveling cover part attached to the blade guard. In a first position, the swiveling cover part may be positioned such that a first portion of the circumference is covered, following the blade guard, and extending an angular distance after the blade guard, in the direction of rotation. The swiveling cover part may be moveable between the first position and a second position where a cutting operation of the rotatable work tool along the first portion of the circumference occurs. The cover part may be biased towards the first position.
