3.9 Setting the carburetor
Note: The cut-off saws are equipped with a speed limiting electronic ignition.
In addition, the carburetor has a fixed nozzle that cannot be adjusted.
• The idle speed has been factory set to approx. 2500 rpm; however, the run-
in procedure of a new machine requires a slight readjustment of the idle
speed.
• The following steps are required to correctly set the idle speed:
• Start the engine and let it warm up (approx. 3 - 5 minutes).
• Make the carburetor setting with the screwdriver that was included in deliv-
ery.
• Readjust the idle speed
• If the cutting disc rotates when the engine is running, screw the stop screw
"S" (2) for the choke outward until the cutting disc no longer rotates. If the em-
gine stops when idling, turn the screw back in somewhat.
Turn off the engine
Set the idle speed with a flathead
screwdriver (head width 4 mm/0.16").
The screwdriver shown has a moulded
nose that can be used as a setting tool.
