An adjustable exhaust assembly for a pneumatic fastening tool having body and a handle extending from the body, the handle defining an inlet channel for receiving input of pressurized gas and an outlet channel for outputting exhaust. The adjustable exhaust assembly includes a base non-rotatably attachable to an end of the handle opposite the body. The base has a plate and a boss extending from the plate. The boss is configured to receive an air hose and defining an inlet opening configured to direct compressed air to the inlet channel. The plate has an outlet opening in communication with the outlet channel. A substantially annular and cap is rotatably received about the boss. The cap defines a substantially annular channel in communication with the outlet opening of the base and an outlet port defined in a portion of a circumferential wall of the annular cap and in communication with the annular channel. Rotation of the cap about the boss moves the outlet opening among a plurality of radial positions relative to the boss.

What is claimed is: 1. An adjustable exhaust assembly for a pneumatic fastening tool having a body and a handle extending from the body, the handle defining an inlet channel for receiving input of pressurized gas and an outlet channel for outputting exhaust gas, the adjustable exhaust assembly comprising: a base non-rotatably attachable to an end of the handle opposite the body, the base having a plate and a boss extending from the plate, the boss configured to receive an air hose and defining an inlet opening configured to direct compressed air to the inlet channel, and the plate having an outlet opening in communication with the outlet channel; a substantially annular cap rotatably received about the boss, the cap defining a substantially annular channel in communication with the outlet opening of the base and an outlet port defined in a portion of a circumferential wall of the annular cap and in communication with the annular channel, wherein rotation of the cap about the boss moves the outlet opening among a plurality of radial positions relative to the boss. 2. The adjustable exhaust assembly of claim 1, wherein the base is non-rotatably attached to the end of the handle by at least one fastener. 3. The adjustable exhaust assembly of claim 1, wherein the inlet opening in the boss includes a portion configured to receive a quick connect for a hose. 4. The adjustable exhaust assembly of claim 3, wherein the portion of the boss is internally threaded. 5. The adjustable exhaust assembly of claim 1, wherein the cap comprises an inner annular wall that abuts against the boss. 6. The adjustable exhaust assembly of claim 5, wherein the cap comprises a middle wall extending radially outwardly from the inner annular wall and an outer annular wall extending downward from the middle wall, where the inner and outer walls are substantially parallel. 7. An adjustable exhaust assembly for a pneumatic fastening tool having a body and a handle extending from the body, the handle defining an inlet channel for receiving input of pressurized gas and an outlet channel for outputting exhaust gas, the adjustable exhaust assembly comprising: a first cover and a second cover, each configured to cover an end of the handle opposite the body, the first cover including an inlet opening in communication with the inlet channel to admit pressurized gas to the inlet channel, the first cover and the second covers each including an outlet opening, the outlet openings in communication with each other and with the outlet channel to release exhaust gas from the outlet channel to atmosphere in a region adjacent to the covers, wherein the second cover is moveable relative to the first cover to direct the exhaust gas in a plurality of directions. 8. The adjustable exhaust assembly of claim 7, wherein the first cover comprises a body portion that includes the outlet opening and a boss extending from the body portion that includes the inlet opening. 9. The adjustable exhaust assembly of claim 7, wherein the second cover comprises a generally cylindrical side wall and a top wall coupled to the side wall. 10. The adjustable exhaust assembly of claim 9, wherein the top wall defines a central hole that receives the protrusion therethrough. 11. The adjustable exhaust assembly of claim 10, wherein the side wall includes the exhaust opening. 12. The adjustable exhaust assembly of claim 10, wherein the top wall and the side wall at least in part define a donut-shaped internal channel in communication with the outlet opening and the exhaust opening. 13. The adjustable exhaust assembly of claim 7, wherein the plurality of directions are generally transverse to an axis of the handle. 14. A pneumatic fastening tool comprising: a body containing a pneumatically actuated cylinder for driving a fastener; a magazine coupled to the body for holding a plurality of fasteners; a handle extending from the body, the handle defining an inlet channel for receiving input of compressed gas to the cylinder and an outlet channel for outputting exhaust gas from the cylinder; an adjustable exhaust assembly comprising a first cover and a second cover, each configured to cover an end of the handle opposite the body, the first cover including an inlet opening in communication with the inlet channel to admit pressurized gas to the inlet channel, the first cover and the second covers each including an outlet opening, the outlet openings in communication with each other and with the outlet channel to release exhaust gas from the outlet channel to atmosphere in a region adjacent to the covers, wherein the second cover is moveable relative to the first cover to direct the exhaust gas in a plurality of directions. 15. The adjustable exhaust assembly of claim 14, wherein the first cover comprises a body portion that includes the outlet opening and a boss extending from the body portion that includes the inlet opening. 16. The adjustable exhaust assembly of claim 14, wherein the second cover comprises a generally cylindrical side wall and a top wall coupled to the side wall. 17. The adjustable exhaust assembly of claim 16, wherein the top wall defines a central hole that receives the protrusion therethrough. 18. The adjustable exhaust assembly of claim 17, wherein the side wall includes the exhaust opening. 19. The adjustable exhaust assembly of claim 17, wherein the top wall and the side wall at least in part define a donut-shaped internal channel in communication with the outlet opening and the exhaust opening. 20. The adjustable exhaust assembly of claim 14, wherein the plurality of directions are generally transverse to an axis of the handle.
