Malfunctions
Malfunctions
In the event of malfunctions immediately deactivate the cleaner and secure it against
inadvertent reactivation. Malfunctions may only be remedied by qualified staff, who must
observe the safety instructions.
Go through the check list below in numerical order.
No Remedying Faults
1
Check the cleaning liquid pressure and flow rate. Check the pressure at the cleaning head
and not at the pump.
For pressure and flow rate requirements refer to chapter “Betriebsbedingungen“
(page 23).
Increase the pressure/flow rate if necessary.
2
Take the Fury cleaner out of the tank. Blank off the nozzles and supply water through a
hose at 2 bar (30 psi). Blanks for the nozzles can be supplied but a simple plug fitting
inside the nozzles will do.
3
Check the inlet tube. Make sure the inlet tube is free from blockage, is not jammed and is
not bent.
4
Rotate the nozzle tube forward and back 1/4 turn.
Check the valve action is positive when it clicks over. The valve should be free and not
bent.
5
Ensure that the valve spindle snaps up and down positively without delay.
6
Undo the bolts, remove the valve block and unscrew the control screw. Check that filter
and control screw are free of blockage. Blow the water passages out with compressed air.
7
Move the index lever forwards and backwards by hand. Check that the inlet tube moves
round in steps.
•
Check that this area is free of oil or grease. Remove with de-greaser if necessary.
•
Ensure the spring is intact and operates correctly.
8
Springs should be tensioned. If necessary, tighten by screwing the spring ends half a turn.
9
Check that all nozzles are free of blockage and the vanes are not damaged.
