Maintenance Of Air Cleaner; Cleaning Of Filter Element - KIRLOSKAR DV Series O & M Manual

Maintenance of air cleaner

• The pre-cleaner (if provided) should be cleaned to remove the accumulated dust, after each day's
work, when the engine is stopped.
• The restriction indicator, mounted on air cleaner near the hose, indicates the condition of the air
cleaner element, when the air element is in good condition, a red signal will be seen through the
transparent window on the indicator when the engine is running and will disappear when engine is
stopped. However, if the element is choked, then the red signal will remain 'ON' even after engine is
stopped. This is an indication that the main filter element must be removed & cleaned or replaced.
NOTES: -
1. If engine performance is poor, but restriction is still within limits, do not change the element. The air
cleaner is probably not at fault.
2. To get those extra service hours out of air cleaner element, make sure the air inlet is away from any
heavy dust clouds caused by operation. Also, make sure that exhaust carbon cannot enter the air
cleaner.
3. Discharge the dust vaccuator valve by pressing apart the lips of the ejection slot.
• Clean the vacuation slot time to time.
• Remove any cakes of dust by pressing together the upper part of the valve.
• Make sure that vacuator valve is not damaged, if required change it
