8. Trouble Shooting Guide
Symptom: Tank cleaning machine will not clean
1. No or insufficient liquid flow.
a. Check fluid supply to ensure that pressure and flow as per the operating
curves are being observed. For this to be properly accomplished, you
should install a pressure gauge as close to the machine inlet as possible,
not further from the tank cleaning machine than 4,5 m or 15 feet.
2. Tank cleaning machine inlet is blocked.
a. Check inlet of machine; position 47; and ensure that no debris or
particles is present. Remember that it was advised earlier in this manual
(page 11) to employ a filter in the supply line.
3. Tank cleaning nozzles are blocked.
a. Remove and dismantle the nozzles, position 1 and 3, and check for any
foreign matter. If present, remove and then reassemble nozzles.
Symptom: Tank cleaning machine will not rotate
4. Bevel gears are blocked.
a. If foreign matter has entered the machine and passed through the
body, it may have lodged itself in the bevel gears; position 7 and 40.
To check these areas refer to “7.4. Disassembly” on page 19. Take care
to review the gearing and ensure that there is no damage that could
prevent operation.
5. Gearbox rotation is restricted.
a. If foreign matter has entered through the stator, position 40, it may have
lodged itself in the gearbox; to perform an inspection see disassembly
instructions.
6. Worn parts; replacements required.
a. After items 1-5 above have been checked; it may be necessary to replace
parts due to normal wear associated with your type of operation (or
possible damage). One of the best ways to determine the need to
replace parts is a visual inspection of the primary wear parts as indicated
on the list at “14. Service Kit Contents” on page 35.
Symptom: Tank cleaning machine runs with wrong speed
7. Check that the pressure and flow is correct.
8. Try changing the rotation speed by adjusting turbine as described on page 15.
