PERIODIC MAINTENANCE

PRECAUTIONS
The Importance of Periodic
Maintenance
Engine deterioration and wear occurs in proportion
to length of time the engine has been in service and
the conditions the engine is subject 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
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.
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 49.
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, 250, 500, 1000, 1500, 2000 and 3000 engine
hours. Failure to perform periodic maintenance will
shorten the life of the engine.
