H. Routine Maintenance CAUTION!

Your machine can be equipped with a low emission carburetor. We recommend that car- buretor adjustment be done, if necessary, exclusively by authorized service centers, which have the appropriate equipment to ensure optimum performance with lower emis- sions.

The correct engine setting at idle speed is 2800 rpm as indicated in the technical specifications of this manual and should not be modified unless by an authorized service center

If the engine does not hold the idle speed, turn the screw T clockwise to increase the rpm and counterclockwise reduce the rpm.

CAUTION! ALL THE ABOVE SETTINGS SHOULD BE MADE WITH THE CUTTING ATTACHMENTS PROPERLY INSTALLED.
