Abstract:
A method for adjusting the idle position of a throttle pull of a portable handheld work apparatus driven by an internal combustion engine having a carburetor, the carburetor having a throttle lever and a throttle flap lever, the throttle pull including a Bowden cable having a cable casing and a cable wire axially guided and axially movable in said cable casing, and said Bowden cable connecting said throttle lever and said throttle flap lever to each other, said throttle lever being movable between a first idle stop and a first full throttle stop and said throttle flap lever also being movable between a second idle stop and a second full throttle stop; and, said throttle pull further including an adjusting device mounted on an apparatus-fixed support location and having a holding element; the method comprising the steps of:moving said throttle flap lever in a direction of full throttle utilizing said throttle lever until one of said levers comes into contact with the full throttle stop corresponding thereto; loosening an existing connection between said holding element of said adjusting device and one of the two ends of said cable casing; axially shifting said one end of said cable casing relative to said holding element so far that said throttle lever and said throttle flap lever come into contact engagement with said first and second full throttle stops, respectively; reestablishing the connection between said holding element and said one end of said cable casing; moving said throttle lever so far in a direction toward said first idle stop so that said throttle flap lever comes into contact engagement with said second idle stop; and, moving said throttle lever through a lost motion distance to said first idle stop.
