If the engine is adjusted for operation above 330 m (1,100 ft.) ASL,
the carburetor must be re-adjusted when operating the engine below
330 m (1,100 ft.) ASL, otherwise severe engine damage may result.
Note: Every unit is run at the factory and the carburetor is set in
compliance with emission regulations. Carburetor adjustments,
other than idle speed, must be performed by an authorized dealer.
◆
The cutting attachment may be moving during carburetor
adjustments.
◆
Wear your protective equipment and observe all safety
instructions.
◆
For units equipped with a clutch, be sure the cutting

When the unit is turned off, make sure the cutting
attachment has stopped before the unit is set down.

Check idle speed and reset if
necessary. If a tachometer is

manual. Turn idle screw (A)
clockwise to increase idle
speed; counterclockwise to
decrease idle speed.
When carburetor adjustment is completed, the cutting
attachment should not move at idle, otherwise serious personal
injury may result.
