A fastener driving device includes a housing having an engine receiving portion and a handle portion. A reservoir is configured to receive a gas having a pressure greater than atmospheric pressure and is at least partially located in the handle portion. A dust blower is configured to allow gas in the reservoir to be selectively communicated to atmosphere through an outlet in the engine receiving portion of the housing. The dust blower includes a passageway extending from the reservoir to the outlet in the engine receiving portion, the passageway at least partially circumnavigating the cylinder of the drive engine, and an actuator configured to selectively open and close the passageway so that when the passageway is open, gas from the reservoir is communicated from the reservoir to the outlet, and when the passageway is closed, the gas from the reservoir is not communicated from the reservoir to the outlet.

1. A fastener driving device comprising: a housing having an engine receiving portion and a handle portion;a drive engine located in the engine receiving portion, the drive engine comprising a cylinder and a piston reciprocally mounted within the cylinder, the piston comprising a driver configured to move along a drive axis to drive a fastener during a drive stroke;a reservoir at least partially located in the handle portion, the reservoir configured to receive a gas having a pressure greater than atmospheric pressure, the reservoir being in fluid communication with the drive engine;a trigger configured to operate the drive engine; anda dust blower configured to allow gas in the reservoir to be selectively communicated to atmosphere through an outlet in the engine receiving portion of the housing, the dust blower comprising a passageway extending from the reservoir to the outlet in the engine receiving portion of the housing, the passageway at least partially circumnavigating the cylinder of the drive engine, andan actuator configured to selectively open and close the passageway so that when the passageway is open, gas from the reservoir is communicated from the reservoir to the outlet, and when the passageway is closed, the gas from the reservoir is not communicated from the reservoir to the outlet. 2. The fastener driving device according to claim 1, wherein the actuator is located on the handle portion. 3. The fastener driving device according to claim 2, wherein the actuator is located near the trigger. 4. The fastener driving device according to claim 1, wherein the housing comprises an elongated chamber, and wherein the actuator comprises an elongated member slidingly received by the elongated chamber, a first seal surrounding a circumference of the elongated member, and a second seal surrounding the circumference of the elongated member and spaced from the first seal along the elongated member, wherein when the elongated member is in a first position, the first seal contacts an inner surface of the elongated chamber to block the passageway, and wherein when the elongated member is in a second position, the first seal does not contact the inner surface of the elongated chamber to open the passageway and allow the gas from the reservoir to flow through the passageway to the outlet. 5. The fastener driving device according to claim 4, wherein the actuator further comprising a biasing member configured to bias the elongated member in the first position. 6. The fastener driving device according to claim 5, wherein the biasing member is a coil spring. 7. The fastener driving device according to claim 5, wherein the elongated chamber comprises a first surface defined by a first diameter, a second surface defined by a second diameter that is larger than the first diameter, and transition surface in between the first surface and the second surface, and wherein the elongated member comprises a portion configured to engage the biasing member on a first side and to engage the transition surface on a second side that is opposite the first side to hold the elongated member in the first position. 8. The fastener driving device according to claim 7, wherein the first seal is located adjacent the second side and configured to engage the transition surface when the elongated member is in the first position. 9. The fastener driving device according to claim 5, wherein the actuator further comprises a push button connected to one end of elongated member, the push button being configured to receive a thumb or finger of a user of the fastener driving device to enable the user to move the elongated member against the bias of the biasing member to move the elongated member from the first position to the second position.
