10. Troubleshooting
If the machine does not run:
1. Check that air pressure and flow is
correct
2. Remove any dirt or debris if present at
the inlet strainer
3. Open the cofferdam plug and try to
start the tank cleaning machine by
opening the inlet valve slowly. Check
that the pressure is correct!
4. Check that the turbine is rotating freely.
Undo the plug (pos. 18) and use an Allen key to rotate the shaft.
5. Inspect the magnet (pos. 39) in the drive unit by taking the drive unit of the
gun unit and try rotating it by hand. Inspect the turbine cover (pos. 101, in
the gun unit) to see if there are any marks indicating that the upper magnet
has been stacked on the cover.
6. Inspect the underside of the turbine cover, undo it with tool 30074, in case
the lower magnet (pos. 103) has been going against the cover, creating
marks. If so, replace the turbine cover and or the magnet.
7. Check that there is no dirt stacking the turbine. After undoing the turbine
cover, undo the screws (pos. 104) in the turbine housing (pos. 107) and use
a pair of tongs to lift it up. Remove any dirt or debris present, and check that
the turbine can rotate smoothly. Adjust the adjusting sleeve if necessary,
see page 20.
If the machine does not clean properly:
1. Check that pressure and flow of supply line is correct
2. Check strainer at inlet and remove any dirt or debris that may be stacked
3. Check that the nozzles are not clogged. Look at the nozzles while starting
the tank cleaning machine, if the water-jet is defuse there might be dirt
stacked in the nozzles. For more instructions about disassembling, see “8.3.
Service Interval”
If the machine runs with wrong speed:
1. Check that pressure and flow of supply line is correct
2. Try changing the rotation speed by adjusting the adjusting sleeve, see “7.7.
Speed Adjustment” on page 20. Note that the tank cleaning machine might
rotate slower in cold climate.
