SERIES 50 OPERATOR'S GUIDE
Item 10 – Air Cleaner
The air cleaner element should be
inspected every 15,000 miles (24,000
km) for vehicle engines, 150 hou rs for
non-vehicle engines, or more often if
the engine is operated under severe
dust conditions. Replace the element,
if necessary. Check the gaskets for
deterioration and replace, if necessary.
If the dry type air cleaner is equipped
with an aspirator, check for aspirator
damage or clogging. Clean, repair or
replace, as necessary.
Dry type air cleaner elements
should be replaced after one year
of serv ice or when the maximum
allowable air intake restriction has
been reached, whichever comes first.
Refer t o section When to Service the
Dry Type Air Cleaner in this guide for
additional information.
NOTICE:
Do not allow the air inlet restriction
to exceed 20 inches of water (5.0
kPa) under any engine operating
conditions. A clogged air cleaner
element will cause excessive
intake restriction and a reduced
air supply to the eng ine. This, in
turn, can result in increased fuel
consumption, inefficient engine
operation and reduced engine life.
Inspect the entire air system for leaks
daily. Look especially for to rn air inlet
piping or boots and lo ose or damaged
clamps. Have worn or damaged parts
repaired or replaced, as required.
Retighten loose connections.
