Engine oil and oil filter change
To change engine oil and oil filter:
1. Run the engine for approximately 5 minutes to
warm up the oil. Stop the engine.
2. Remove the oil drain plug (1). Its position may
vary depending on the engine application.
3. Drain crankcase oil from the engine while warm.
4. Loosen and remove the filter element (2) by using
a suitable filter wrench. Discard the oil filter
element. The position of the oil filter may vary
depending on the engine application.
5. Apply clean engine oil to the inner and outer seals
of the new filter (3) and to the filter threads.
6. Wipe both sealing surfaces of the header (4) with
a clean rag.
7. Ensure the notches in the dust seal (5) are properly
installed in the slots of the housing. Replace the
dust seal if damaged.
8. Install the filter element,
hand tighten only
. A
filter wrench should be used for removal only.
9. Install and tighten the oil filter by hand, until it is
firmly seated against the dust seal. DO NOT apply
an extra 3/4 or 1-1/4 turn after gasket contacts, as
done for standard filters.
10. Fill the engine crankcase through the oil filler cap,
using the correct Atlas Copco engine oil.
Observe all relevant environmental
and safety precautions.
Be sure to stop the engine before
draining engine oil or changing the
oil filter cartridge.
Allow the engine to cool down
sufficiently; oil can be hot and cause
burns.

Filtration of engine oil is critical to
proper lubrication. Therefore,
change the oil filter regularly,
respecting the intervals specified in
the “Maintenance schedule”.
Use an oil filter, meeting the Atlas
Copco performance specifications.
!
Immediately after completing the oil
change, crank the engine for 30
seconds, without permitting the
engine to start. This will help to
insure adequate lubrication of the
engine components, before the
engine starts.
