<p>A handheld power tool, specifically a combustion nailer tool (10), including a tool housing (12), a combustion source (14) disposed in the housing (12). The tool has a valve sleeve (24) reciprocating relative to a cylinder head along a longitudinal tool axis (A) between a rest position and a pre- firing position, a fuel cell chamber (34) in the housing (12) in operational proximity to the combustion source (14) and dimensioned for accommodating a fuel cell. It also includes at least one pivot point (56) associated with the fuel cell chamber (34) transverse to the tool axis (A) for facilitating movement of the fuel cell between a non-activated position and an activated position, and at least one actuator (50) pivotable about the pivot point (56) and extending from the pivot point (56) at least to the tool axis (A) for engaging the valve sleeve (24). The apparatus requires a reduced actuation force in order to combat user fatigue.</p> |
