Clean the holes of the nozzles with a
needle (fig. 20).
Always keep the two scrapers of the
recovery tank clean.
This procedure should be carried
out after every machine operation.
GENERAL MAINTENANCE
The mechanical parts of the DUPLEX do not require periodic maintenance
as their gearings all run on bearings.
IMPORTANT PRECAUTIONS
At times it may happen that the electric cord gets tangled up underneath the
brushes of the machine. Do not under any circumstances attempt to extract
the cord while the machine is in operation. First take the handle up to the
vertical position.
Disconnect the plug from the power point and before reinserting it check the
cord to make sure that it has not been damaged.
In the event of the cord being damaged after being caught up underneath the
machine, do not simply repair it with tape but have it checked and repaired by
a qualified technician.
Whenever in the rest position the DUPLEX must never rest on the brushes as
the weight of the machine itself could deform them. It must always be raised
up from the brushes and supported by the four castors that come down
automatically when the register is in the “RT” position (see Translation page
16)
Do not pour water or other liquids on top of the machine.
For all maintenance operations unplug the power supply cord from the power
point.
