A handheld work apparatus includes a work tool. The work apparatus defines a longitudinal plane and includes a handle having a longitudinal axis. The blocking lever is mounted so as to be pivotable about a rotational axis. The blocking lever blocks the actuating lever in a blocking or disable position and enables the actuating lever for actuation in at least one operating enable position. In the direction of view perpendicular to the longitudinal plane, the longitudinal axis of the handle and the rotational axis of the blocking lever conjointly define an angle (α). The angle (α) lies in a range of from 10° to 60°.

A pressure washer includes a connection for a fluid source, a pump, a motor. A main line has a suction chamber between a connection to a spray opening and a pump and a pressure chamber between the pump and the spray opening which are fluidically connected via a bypass line. To regulate the pressure in the pressure chamber, a free cross-sectional surface of the bypass line is adjustable. A switch-off unit causes, as a result of the pressure prevailing in the pressure chamber, that the motor is in the off-state if the pressure chamber pressure corresponds at least to a pressure threshold. A pressure build-up valve is arranged in the bypass line reducing the free cross-sectional surface of the bypass line to such an extent when a volume threshold of flow through the bypass line is exceeded, the pressure in the pressure chamber corresponds at least to the pressure threshold.

A two-stroke engine possesses a cylinder, in the cylinder bore of which a combustion chamber is formed. The combustion chamber is bounded by a reciprocating piston, which drives a crankshaft rotatably mounted in a crankcase. A crankcase interior is fluidically connected to the combustion chamber across at least one transfer channel in at least one position of the piston.

A high-pressure cleaning appliance includes a connection for a liquid source, a delivery pump, a motor for driving the delivery pump, a delivery line through which liquid can be delivered from the connection to a spraying-out opening of the delivery line via the delivery pump, and a valve which is arranged in the delivery line. The motor has two operating states. The two operating states include an off state and an on state. The valve has two valve states, wherein the two valve states include a closed state and an open state. In the closed state, the valve prevents a flow of liquid through the delivery line. In the open state, the valve allows a flow of liquid through the delivery line. The high-pressure cleaning appliance is structurally configured in such a way that the adjustment of the operating state of the motor is possible only if the valve is in the open state.

A method determines at least one power contact resistance or at least one resistance value corresponding to the at least one power contact resistance between at least one pack power contact of a battery pack and at least one apparatus power contact of an electrically driven work apparatus or of a charging apparatus. The pack power contact and the apparatus power contact touch one another and are loaded with a power current. The battery pack and the work apparatus or the charging apparatus are electrically connected by a data communication line for transmitting a data communication signal. The method determines the power contact resistance or the resistance value by comparing a signal voltage variable of the data communication line and a power voltage variable of the at least one pack power contact or of the apparatus power contact with one another, wherein the signal voltage variable or the power voltage variable is dependent on a voltage drop caused by the power current and the at least one power contact resistance.
