1.Place the unit on the ground, then start the engine, and then allow it to idle
2.If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw
3.If a tachometer is available, the engine idle speed should be final adjusted to 2,750 (±250) RPM
4.Carburetor fuel mixture adjustments are preset at factory on units with emission control systems and cannot be serviced in the field.
Checking Unit Condition
NEVER operate the unit with the cut- ting attachment shield or other protective devices (harness, ignition switch, blade retention clip, etc.) removed!

A cutting attachment shield or other protective device is no guarantee of protection against ricochet. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS!
