GENERAL INSPECTION
Prior to each use, the air compressor should be cleaned
and inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for fuel,
oil, and coolant leaks. Use Table 9 as a general guideline
for engine maintenance.
AIR CLEANER (DAILY/500 HOURS)
This Isuzu diesel engine is equipped with a replaceable,
high-density paper air cleaner element (Figure 48).This air
cleaner is equipped with an inner element that is used as a
backup filter should the main element become damaged.
Remove air cleaner elements and clean the heavy duty
paper element with a light spray of compressed air. Replace
the air cleaner element every 500 hours.

NOTICE
If the engine is operating in very
dusty
or
dry
grass
conditions, a clogged air cleaner will result. This can
lead to a loss of power, excessive carbon buildup in
the combustion chamber, and high fuel consumption.
Change air cleaner
more frequently
if these conditions
exist.
CAUTION
Wear protective equipment such as
approved safety glasses or face shields
and dust masks or respirators when
cleaning air filters with compressed air.
