PERIODIC MAINTENANCE

INTRODUCTION

This section of the Service Manual describes the
procedures for proper care and maintenance of the
engine.
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! 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.

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.

EPA REQUIREMENTS

To maintain optimum engine performance and
compliance with the Environmental Protection
Agency (EPA) Regulations for Engines, it is
essential that you follow the See Periodic
Maintenance Schedule on page 4-6 and the See
Periodic Maintenance Procedures on page 4-9.
EPA Requirements for USA and
Other Applicable Countries
The EPA emission regulation is applicable only in
the USA and other countries that have adapted the
EPA requirements in part or in whole. Determine
and follow the emission regulations in the country
where your engine will be operating to assist you in
specified compliance.
The following are the requirements for the EPA.
Unless these requirements are met, the exhaust
gas emissions will not be within the limits specified
by the EPA.
See See Conditions to Ensure Compliance with
EPA Emission Standards on page 4-5. Clean or
replace the air cleaner element if the air intake
restriction exceeds the referenced specifications.
