Adjustments<br />
Yanmar recommends that only idle speed adjustment<br />
should be performed by non-authorized service technicians.<br />
Refer to Chapter Three for the idle speed procedure.<br />
Other adjustments, such as no-load maximum governed<br />
speed and fuel limiter screw setting, are set by the<br />
manufacturer. Incorrect adjustment can damage the engine.<br />
To prevent tampering, a safety wire is attached to<br />
each screw and a lead seal is affixed to the wire or the<br />
screw assembly is marked (Figure 46). Removing or cutting<br />
the wire or seal or altering the marked screw position<br />
will void the engine warranty.
