PRECAUTIONS
The Importance of Periodic
Maintenance
Engine deterioration and wear occur in
proportion to the length of time the engine
has been in service and the conditions the
engine is subjected to during operation.
Periodic maintenance prevents unexpected
downtime, reduces the number of accidents
due to poor machine performance and helps
extend the life of the engine.
Performing Periodic
Maintenance
WARNING! NEVER block windows,
vents, or other means of ventilation if
the engine is operating in an enclosed
area. All internal combustion engines
create carbon monoxide gas during
operation. Accumulation of this gas
within an enclosure could cause illness
or even death. Make sure that all
connections are tightened to
specifications after repair is made to the
exhaust system. Failure to comply could
result in death or serious injury.
Perform periodic maintenance procedures
in an open, level area free from traffic. If
possible, perform the procedures indoors to
prevent environmental conditions such as
rain, wind, or snow from damaging the
engine.
The Importance of Daily Checks
The Periodic Maintenance Schedule
assume that the daily checks are performed
on a regular basis. Make it a habit of
performing daily checks before the start of
each operating day. See Daily Checks on
page 40.
Keep a Log of Engine Hours and
Daily Checks
Keep a log of the number of hours the engine
is run each day and a log of the daily checks
performed. Also note the date, type of repair
(e.g., replaced alternator), and parts used
for any service needed between the periodic
maintenance intervals. Periodic
maintenance intervals are every 50, 250,
500, and 1000 engine hours. Failure to
perform periodic maintenance will shorten
the life of the engine.
Yanmar Replacement Parts
Yanmar recommends that you use genuine
Yanmar parts when replacement parts are
needed. Genuine replacement parts help
ensure long engine life.
