Safety Precautions
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."
CAUTION
Never use a steel wire brush to clean
fuel injectors. Damage to the nozzle and
other components is likely to result.
CAUTION
Allow the engine to warm-up for at least
five minutes and the idle speed of the
engine to return to normal before
engaging the transmission or any PTOs.
Engaging the transmission or PTO at an
elevated engine speed could result in an
unexpected movement of the
equipment.
