Annually
Every 5th year
1. More often if required.
2. Earlier if low pressure indicator shows red.
3. If inhibitor has not been topped up for five years, the coolant should be changed.

Lepaskan mur dan angkat
cover oil cleaner.
Perhatian : Hati-hati pada saat
membuka tutup, kemungkinan
oli masih panas.
Cuci semua part tersebut
didalam solar.
Pasangkan kembali O-ring ke
mangkuk rotor.
Pastikan O-ring tidak rusak.
Ganti jika memang diperlukan.
Tarik rotor dan longgarkan
mur pada mangkuk rotor
sebanyak 3 putaran.
Memasang rotor kembali.
Kencangkan kembali mur
pelan-pelan dengan tangan.
Jika mur macet : jepitkan
mur (bukan rotornya) pada
ragum dan putar rotor
sebanyak 3 putaran
menggunakan tangan atau
dengan memakai obeng.
Sesuaikan kembali posisi
rotor.
Pastikan bahwa rotor dapat
berputar dengan mudah.
Ketuk mur pelan-pelan dengan
menggunakan tangan atau
palu plastik, untuk
melepaskan mangkuk rotor
dari Bottom plate.
Lepaskan mur dan angkat
mangkuk rotor.
Ungkit pelan-pelan untuk
melepaskan saringan dari
Bottom plate.
Bersihkan endapan kotoran di
dalam mangkuk rotor. Jika tidak
ada endapan, hal ini menandakan
bahwa cleaner tidak berfungsi
dengan baik.
Jika tebal endapan melebihi 20mm :
Harus lebih sering dibersihkan !
Pastikan O-ring mangkuk rotor
tidak rusak. Ganti jika O-ring
mengeras atau rusak.
Tutup mangkuk dan kencangkan
mur.
Jika mur dikencangkan
memakai alat, hal ini dapat
merusak shaft rotor, mur dan
mangkuk rotor.
Rotor akan terus berputar
beberapa saat setelah mesin
dimatikan.
Matikan mesin jika suhu rotor
memanas.
Dengarkan suara desingan dari
rotor atau rasakan getaran dari
bagian luar cleaner.
Rotor normalnya terus berputar
selama 30-60 detik setelah mesin
dihentikan.
Jika tidak, bongkar dan periksa !
PERHATIAN : BERSIHKAN OIL CLEANER SECARA RUTIN BERSAMAAN DENGAN PENGGANTIAN OLI

3. Every 400 hours:
CLEANING THE OIL CLEANER
(at same time as an oil change)
- Clean the cover. Unscrew the nut and remove the cover.
Open the cap carefully.
The oil may be hot.
- Lift out the rotor and loosen the nut on the rotor bowl three turns.
- If the nut is jammed:
Clamp the nut, absolutely not the rotor, in a vice and turn the rotor three
turns by hand or with a screwdriver.
- Tap the nut lightly with your hand or a plastic hammer, to detach the
rotor bowl from the bottom plate.
- Unscrew the nut and remove the rotor bowl.
- Remove the strainer located on the rotor. If the strainer is stuck, you can
prise its bottom edge carefully until it comes loose from the bottom
plate.
- Scrape off the deposits from the inside of the rotor bowl. If there are no
deposits, this indicates that the cleaner is not working properly.
- If the deposits are thicker than 20 mm: clean more often.

- Wash all parts in diesel oil.
- Make sure the nozzles on the rotor are not blocked or damaged.
- Make sure the bearings are not damaged.
- Fit the O-ring in the rotor bowl. Make sure it is not damaged.
Change if necessary.
- Reassemble the rotor.
- Tighten the rotor nut firmly by hand.
- Make sure the shaft is not loose. If it is loose, use locking compound
561 200 and tighten it to a torque of 34 Nm.
- Refit the rotor.
- Check that it rotates easily by rotating it manually.
- Check that the O-ring in the bowl is undamaged.
A hardened or damaged O-ring must be changed.
- Screw on the bowl and tighten the lock nut to 15 Nm.
Tighten the nut carefully so as not to damage the rotor shaft, nut or bowl.
Functional inspection
The rotor rotates very fast and should continue to rotate when the engine has
stopped.
- Stop the engine when it is warm.
- Listen for a whirring sound from the rotor or feel whether the cleaner
housing is vibrating.
The rotor normally continues spinning for 30 - 60 seconds after the engine
has stopped.
If it does not: dismantle it and inspect the component parts.
