15. - Trouble-shooting
• the motor will not start
- a fuse may have blown and needs replacing.
- the cable or the wall socket may be defective and needs
checking.
• the suction power is reduced- the dust bag may be full
and needs replacing,
- the filter may be clogged and needs shaking,
- The by pass valve is open
The by pass valve protects the motors against an overheating
that may occur when there is not enough cooling air.
You should not release this mechanism unnecessarily by closing
the suction inlet with your hand while the machine is working.
When the hose or the tube is blocked or the filter needs to be
cleaned, the airflow is interrupted or not longer sufficient and
the by pass valve opens. It is not necessary to shut down the
system while removing the blockage. Having done that, you
may continue with your work.
• the vacuum cleaner stops
- the thermal cut-out has switched of the motor as a result
of an obstruction of the hose, wand or nozzle. Remove the
cause of the obstruction.
- when the motor is cool, it will automatically start again.
