CARBURETOR ADJUSTMENT

The carburetor has been carefully adjusted at the factory and should not
require any further adjustment. Only the idling speed can be adjusted by
turning the idle speed adjustment screw (see sketch). The correct speed
for model BC2259, BC2259H and BC329H are 2700 - 3300 RPM, and for
others are 2400 - 2800 RPM (or just below the clutch engagement speed).
Turning the adjustment screw clockwise will increase the idle speed.
If further adjustment is necessary, please contact a local authorized
MARUYAMA dealer.
OPERATING THE BRUSHCUTTER

fastening parts are correctly secured.
