A power-tool cooling apparatus for a portable power tool includes a first fan configured to generate a first cooling fluid flow to cool a drive unit of the portable power tool, and a second fan that generates a further cooling fluid flow to cool an electronics unit of the portable power-tool. A third fan generates a third cooling fluid flow to cool a second electronics unit of the power-tool, and supplies cooling fluid to the first cooling fluid flow.

Power-tool cooling apparatus

The disclosure relates to a circular saw, in particular a hand-held circular saw, having a housing and a drive unit, at least some sections of which are arranged in the housing and with which a tool holder for an exchangeable saw blade is associated. The drive unit is designed to rotationally drive the exchangeable saw blade about an associated axis of rotation. In the circular saw, a blade guard is associated with the exchangeable saw blade. The blade guard is mounted in the housing for rotation about the associated axis of rotation and extends around a cutting point of the exchangeable saw blade at least during a sawing operation in such a way that contact with the cutting point can be at least substantially prevented.

Circular saw, in particular hand-held circular saw

A power-tool cooling apparatus for a portable power tool comprises at least one cooling unit configured to generate a cooling fluid flow to cool a drive unit of the portable power tool, and at least one further cooling unit configured to generate a further cooling fluid flow. The at least one further cooling unit is designed to differ from the at least one cooling unit.
