CAUTION
• NEVER remove or attempt to remove
the tamper-proof devices from the
full-load fuel adjusting screw or the
high-speed throttle limit screw on the
fuel injection pump and governor
assembly. These adjustments have
been made at the factory to meet all
applicable emissions regulations and
then sealed.
• NEVER attempt to make any
adjustments to these sealed
adjustment screws. If adjustments are
required, they can be made only by a
qualified fuel injection shop that will
ensure the injection pump continues
to meet all applicable emissions
regulations and then replace the
tamper-proof seals.
• Tampering with or removing these
devices may void the “Yanmar Limited
Warranty.”

injection pump.
Failure to rewrite the fuel injection
data before replacing the fuel injection
pump will void the engine warranty.
