Thermal cut-out protection
The vacuum cleaner is equipped with a thermal cut-out to protect
the motor and other vital machine parts from overheating. Should
the machine cut out, you will have to wait at least 5-10 minutes for
it to automatically reset. While you are waiting, switch the machine
off and unplug it, then check the hose, dust bag and filters to be sure
that nothing is blocking the flow of air through the machine.
Fault finding
• the motor will not start
– a fuse may have blown and needs replacing.
– the cable may be defective and needs checking.
• the suction power is reduced
– the dust bag may be full and needs replacing.
See point 3.
– the dust filters may be clogged and need replacing.
See point 3-4-7.
– the hose, tube or nozzle may be blocked and needs to be
cleared.
• the vacuum cleaner stops
– the thermal cut-out has switched off the motor as a result of an
obstruction of the hose, tube or nozzle.
Remove the cause of the obstruction.
Maintenance
Always keep the cleaner in a dry place. The cleaner is designed for
continuous heavy work. Depending on the number of running hours
- the dust filters should be renewed.
Keep the container clean with a dry cloth, and a small amount of
spray polish.
