Abstract
To improve an intake device (100) for a handheld tool implemented having an air cleaner, particularly for a chainsaw, a cuffing-off grinder, or the like, which comprises an internal combustion engine (25) and a drive unit (20) for the attachment, the air cleaner cleaning combustion air, which is charged with dirt particles, for the engine (25), in that a centrifugal separator (30) separates the combustion air into at least one first air flow (31), which is freed from dirt particles as much as possible, and a second air flow (32), which is loaded with dirt particles, in particular to cause higher efficiency of the intake device, it is suggested that a blower (10) be situated on the drive unit (20), which sucks in the second air flow (32), by which cooling of the drive unit (20) is caused.
