8. Trouble Shooting Guide
Symptom: Tank cleaning machine will not clean
Possible causes are:
1. No or insuffi cient liquid fl ow
a. Check fl uid supply to ensure that pressure and fl ow 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 (pos. 1) and ensure that no debris or particles
is present. Remember that it was advised earlier in this manual (page
11) to employ a 100 micron fi lter.
3. Tank cleaning nozzles are blocked.
a. Remove the nozzles (pos. 17) and check for any foreign matter. If
present, clean the nozzles and then remount them.
Symptom: Tank cleaning machine will not rotate
Possible causes are:
4. Bevel gears are blocked.
a. If foreign matter has entered the machine and passed through the
turbine, it may have lodged itself in the bevel gears (pos. 8 and pos 14).
To check these areas refer to “7.4. Disassembly” on page 16. 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 (pos. 8) it may have
lodged itself in the gearbox; to perform an inspection see “7.4.
Disassembly”.
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
in “11. Spare Parts List - BIO 10” on page 26.
