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 machine.

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 shift. See Daily Checks on
page 41.
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 needed for any service
needed between the periodic maintenance
intervals. Periodic maintenance intervals are every
50, 200, 400, 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.

procedure make sure you have the tools you need
