PERIODIC MAINTENANCE
6SY Operation Manual
75
Performing Periodic
Maintenance
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
Periodic Maintenance Schedules 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 44.
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, 750, 1000 and
2000 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.
Tools Required
Before you start any periodic maintenance
procedure make sure you have the tools
you need to perform all of the required
tasks.

A
WARNING
EXHAUST HAZARD!
• NEVER operate the engine in
an enclosed area such as a
garage, tunnel, underground
room, manhole or ship’s hold
without proper ventilation.
• 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.
