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