4 MAINTENANCE
4.1 Safety instructions
• When cleaning and servicing the machine or changing parts, pull out the mains connector plug.
• The machine must not be cleaned with high pressure steam cleaners or powerful liquid jets.
• For reparations use only original Wetrok spare parts.
Important:
Before commencing any maintenance work, switch off the machine and unplug it from the mains.
Emptying dust
Replace the paper filter bag as soon as it is 2/3 full. When working without paper filter bag, empty the suction tank regularly. At each emptying, thorough-
ly clean the protective filter by beating or brushing. If possible, use another vacuum cleaner.
Emptying water
When the tank is full, the high positioned float interrupts the suction flow. Take out the water suction device and empty the waste water tank.
The water suction device has always to be installed tor wet vacuuming.
Wipe the outer surface of the machine, especially the mains cable, from time to time with a damp cloth.
5 CORRECTIVE MAINTENANCE
We recommend that repairs and inspections are carried out by the Wetrok Service Agent. A maintenance agreement is available.
5.1 Fault-finding and rectification
Dry vacuuming:
•
Paper filter bag or suction tank overfilled?
•
Suction pipe, suction hose or nozzle obstructed?
•
Protective filter coated with dust?
The suction motors of Duovac 50 are provided with a thermal overload switch, which shuts off the motors automatically if they overheat. It switches the
motors on again as soon as they have cooled off.
Wet vacuuming:
•
Float sticking to valve aperture?
•
Use of a too strongly foaming detergent, causing float to respond too early?
•
Water suction device not correctly positio-ned?
•
No effective sealing between the suction head and the suction tank?
