CORRECTIVE MAINTENANCE
Wetrok machines are tested in the works for safety. For reliable operation and maintenance of value, regular servicing must be performed.
Servicing shall only be performed by the Wetrok Service Department or authorised specialists.

Paper filter bag overfilled?
•
Suction pipe, suction hose or nozzle obstructed?
•
Inlet filter coated with dust?
•
Exhaust air filter obstructed?
•
Secondary air valve open at handle?
•
Motor shut off by thermal overload switch (overheating)?
The suction motor of the Monovac 6 and 11 is provided with a thermal overload switch. This shuts off the motor automatically if it overheats. After coo-
