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.
