Air Cleaner; Valve Clearance/Others - Isuzu 4LE2 Owner's Manual

INSPECTION AND MAINTENANCE
The air cleaner cleans the air that is sent to the engine by removing the dust and
other impurities contained in the air.
When the element of the air cleaner is dirty, the intake air volume decreases, which
cause drop in engine output or engine malfunction. Also, when the element is
damaged, the cylinder portion or valve may wear due to the dust sucked in, which
may lead to increase in oil consumption or drop in engine output, and not only shorten
the engine service life but also cause a engine failure or an accident. In addition, for
the engine with turbocharger, it can cause a failure or an accident of the turbocharger
itself.
For handling the air cleaner, perform periodic inspections and maintenance as
specified by the machine manufacturer. Also, for use in a dusty environment, consult
the machine manufacture for application of a pre-filter.
CAUTION
• When using in a dusty environment, shorten the interval of cleaning or
replacement.
• When a damage is found on the air cleaner during cleaning, replace the
element.
• When disassembling the air cleaner, be careful not to cause an air leak.
The following items are the inspection and maintenance items that enable smooth
and long-term use of the engine and require specialized maintenance techniques.
In accordance with the periodic inspection and maintenance list, consult the
machine manufacturer or the nearest Isuzu Distributor periodically for inspection and
adjustment.
ADVICE
• Inspection and maintenance should be performed by personnel who are
qualified or experienced in maintenance. A general user or inexperienced
person should not perform the works.
