The present disclosure relates to an arrangement for transferring fluid to a guide bar in a chain saw. A channel can extend from a chain saw body to the fastening arrangement of the guide bar. The channel can include a cavity through the entire channel, a first end of the cavity being connected to a feed channel provided in the chain saw body and a second end thereof to a counter channel provided in the fastening arrangement. The counter channel, in turn, is arranged to extend to the guide bar. The channel is thus arranged to guide fluid flowing in the feed channel provided in the chain saw body through the channel and further through the counter channel provided in the fastening arrangement to the guide bar.

A handheld work apparatus includes a drive motor, an operating-fluid tank and a motor carrier on which the drive motor is held. The operating-fluid tank has a first housing section and a second housing section. The first housing section is realized so as to be integral with the motor carrier. At least a portion of the second housing section is formed from light-transmitting material to permit discerning the fill level of the operating-fluid tank. The motor carrier has a light-transmitting light conductive element for conducting light into the operating-fluid tank.
