5.Periodic Inspection/Maintenance
5-9
5.5.6 Change compressor oil filter
[At 300 hours for the first change and every 1,000 hours thereafter]

Poor quality oil filters do not trap dust sufficiently and will cause damage to the bearings in a short
period.
① Remove the cartridge“1”, using a filter wrench.
② Screw in the new cartridge“1”with the packing“2”
coated slightly with oil. (For part number, see 5.4)
③ After the packing“2”touches the sealing face, further
tighten it by turning it 3/4 time with the filter wrench.
④ After installing the oil filter, check it for any leak during
operation.
5.5.7 Clean strainer in the scavenging orifice
[Every 500 hours]
① Remove the pipe“1”, using a spanner.
② First remove the bushing“2”.
③ Then remove the strainer“3”.
④ Wash the removed strainer“3”in diesel oil and blow out
“dust” by air blowing.
⑤ After finishing the cleaning, install the strainer“3”
again in the reverse procedure.
5.5.8 Change air filter element
[Every 500 hours]

Air filter is an important part which is crucial to machine's performance and life.
Be sure to use genuine parts.
① After removing the cap“1”by loosening its latch“2”,
clean its interior properly.
② Remove the element“3”and then replace it with a
new one.
(For part number, see 5.4)
③ When installing the cap“1”after finishing the
replacing job, push the element into the case“4”
surely by hand, and then make sure that the latch
“
2”fixing the cap surely hooks the case“4”. Finally
tighten it.
 When used or operated under bad conditions, it is
better to remove all the elements, check them, clean
them and replace them earlier before the intervals
listed in maintenance table, if they are found
difficult to be repaired.
