The invention relates to a hand-held power tool having a tool and an internal combustion engine, having a parking position. The internal combustion engine comprises a cylinder in which a piston is mounted in a reciprocating manner. The piston drives a crankshaft which is rotatably mounted in a crankshaft housing. The internal combustion engine includes an intake passage having an intake passage section formed in the fuel supply. The suction passage is divided into a mixture passage and an air passage by a partition wall. The internal combustion engine comprises an air filter and a shock absorber is formed in a cleaning chamber of the internal combustion engine. The shock absorber has a first confluence opening at which the air channel transitions from the shock absorber to the cleaning chamber and a second confluence opening at which the mixture channel transitions from the shock absorber to the cleaning chamber. The air channel and the mixture channel are guided completely separately from each other in the s
