Abstract: A handheld work apparatus has a combustion engine which drives a tool of the work apparatus via a centrifugal clutch. The centrifugal clutch couples in an engagement rotational speed range (nK) which extends between a lower engagement rotational speed (nu) and an upper engagement rotational speed (no). The engine has a fuel supply device, an ignition device, a control device and a device for detecting the rotational speed (n) of the engine. A method for operating the handheld work apparatus makes provision for the rotational speed profile of the combustion engine to be monitored in the engagement rotational speed range (nK) and for the power (P) output for driving the tool to be increased from an operating power (P1) to an increased power (P2, P3) when the rotational speed profile corresponds with a predetermined rotational speed profile over a predetermined period of time (?t).

Accordingly, the first clamp member (21) and the second clamp member (31) are moved to be close to each other. As a result, an auxiliary handle attachable part (140) of a screw driver (100) is clamped by the first clamp member (21) and the second clamp member (31), and thereby the auxiliary handle (10) is attached to the screw driver (100).

Abstract: A combustion driven fastener hand tool is disclosed having a piston driven by combustion within a chamber, the piston affixed to a driver for forcing a fastener. The piston forms a retention chamber having a lower internal pressure (“vacuum”) than that of the surrounding combustion chamber when the piston is disposed in the starting position for operation of the device. The lower internal pressure of the retention chamber (generated from a previous combustion cycle) momentarily holds the piston in place such that combustion behind the piston must first increase sufficiently to overcome holding force of the retention chamber before the piston moves. Requiring build up of combustion chamber pressure before piston motion greatly improves efficiency and power of the device. Use of the vacuum retention chamber is readily tunable with proper sizing of the chamber.
