<p>Embodiments herein relate to a chain saw comprising a chain sharpening member (200) connected to a body portion (110) of the chain saw (100) and arranged for sharpening links (310) of a saw chain (300) mounted on a guide bar (400) and a drive sprocket (500) of the chain saw (100), the chain sharpening member (200) being selectively displaceable from a resting position (250) in which the chain sharpening member (200) is separated from the saw chain (300), to a sharpening position (260) in which the chain sharpening member (200) engages one or more links (310) of the saw chain (300) as the links traverse the drive sprocket (500). The chain saw furthermore comprises a chain brake mechanism and a front hand guard (600) pivotably connected to the body portion (110) and operatively connected to the chain brake mechanism, the front hand guard (600) being selectively pivotable relative to the body portion (110) from an idle position (650) associated with an inactivated state of the chain brake mechanism to a first activated position (660) associated with an activated state of the chain brake mechanism. The front hand guard (600) is operatively connected to the chain sharpening member (200), the front hand guard being selectively pivotable relative to the body portion (110) from the idle position (650) associated with the resting position (250) of the chain sharpening member (200) to second activated position (670) associated with the sharpening position (260) of the chain sharpening member (200).</p> |
