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
CAUTION
The maximum air intake restriction shall
be 0.43 psi (2.94 kPa; 300 mm Aq) or
less. Clean or replace the air cleaner
element if the air intake restriction
exceeds the above mentioned value.

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.
