Precautions

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

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.
