Troubleshooting - comoc CA30 Manual De Uso Y Mantenimiento

N.B: If the previous operations have not resolved the low vacuum, switch off the machine and
remove blockage from the vacuum hose or from the accessories being used.
Cleaning wet surfaces:
1. Check that the vacuum motor control switch is in the "0" position, otherwise turn the switch to the off
position (Fig.04).
2. Check that the plug on the power cable is connected to the power supply socket, otherwise
disconnect it.
WARNING: To prevent damaging the power cable, disconnect the plug from the mains socket by
directly pulling the plug and not the cable.
3. Free the vacuum head (Fig.06) and check that the cloth filter has been removed (Fig.11).
N.B: If cartridge filters or dust collection bags are used instead of the cloth filter, make sure they
have been removed.
4. Check that the foam filter has been fitted below the vacuum head (Fig.12).
N.B: For use on wet surfaces, ensure that the inside of the collection tank is free of any dust
before use. The accessory with the squeegee rubbers should always be used for use on wet
surfaces and the cloth filter should ideally be removed.
5. Secure the vacuum head to the collection tank (Fig.09-10).
6. Plug the power cable into the mains socket.
ATTENTION: Do not exceed the maximum mains impedance value allowed for the electrical
connection point (see Technical Data). Please contact your electrical energy supplier if in doubts
concerning mains impedance on the connecting point.
7. Switch on the appliance by positioning the vacuum motor switch to position "I" (Fig. 4).
N.B: If the appliance is supplied with two vacuum motors switch on one or two depending on the
type of work to be carried out.
8. Start work.
If when working a reduction in the vacuuming power is noted or the noise of the appliance becomes
louder:
• Switch off the appliance, position the vacuum motor switch to position "0" (Fig. 4).
• Remove the plug from the power socket.
WARNING: To prevent damaging to the mains socket, disconnect the plug from the mains socket
by directly pulling the plug and not the power cable.
• Loosen the latch hinges of the vacuum head and remove it (Fig. 6-7).
• Empty the collection tank.
N.B: The place intended for this operation must comply with local environmental regulations.
• remove the foam filter and clean it (Fig.13), clean the mechanical float also (Fig.14).
• When dry, fit the foam filter again (Fig.12).
• Reassemble the vacuum head (Fig.9-10).
• Start working again.
Take the appliance to the designated machine storage place after work is completed.
ATTENTION: Park the appliance in an enclosed place, on a flat surface; near the appliance there
must be no objects that could either damage it, or be damaged through contact with it.
EMPTYING THE COLLECTION TANK
At the end of the work, and before carrying out any type of maintenance, perform the following
operations:
1. Take the appliance to where its collection tank is emptied.
N.B: the place designated for this operation must comply with current environmental
protection regulations.
CAUTION: These operations must be carried out using gloves to protect the hands.
2. Check that the vacuum motor control switch is in the "0" position, otherwise turn the switch to
the off position (Fig.04).
3. Check that the plug on the power cable is connected to the power supply socket, otherwise
disconnect it.
WARNING: To prevent damaging the power cable, disconnect the plug from the mains socket
by directly pulling the plug and not the cable.
4. Free the vacuum head (Fig.06) and lay it on the ground.
5. Empty the collection tank.
N.B: If present, remove the filter - collection bag from inside the collection tank, being
careful not to rip it. If the bag is made of paper, dispose of it properly, but if it is made of
fabric just empty it.
N.B: If the appliance has a tilting system, grip the front handle to turn the tank when being
emptied.
6. Refit all the parts.
MAINTENANCE
When the work is finished and before putting the appliance away, carry out the following
maintenance:
1. Take the device to its maintenance area.
CAUTION: These operations must be carried out using gloves to protect the hands.
2. Check that the vacuum motor control switch is in the "0" position, otherwise turn the
switch to the off position (Fig.04).
3. Check that the plug on the power cable is connected to the power supply socket,
otherwise disconnect it.
WARNING: To prevent damaging the power cable, disconnect the plug from the
mains socket by directly pulling the plug and not the cable.
4. Free the vacuum head (Fig.06) and lay it on the ground.
5. If there is an air inlet cloth filter in the tank, remove it (Fig.11).
6. Clean the filter with a jet of air from a distance of at least 20 cm. Replace it if damaged.
N.B: If cartridge filters or dust collection bags (cotton version) are used instead of
the cloth filter, clean them with a jet or air and check the state of their wear, and if
necessary replace them.
7. If there is a foam filter in the tank, remove it (Fig.13).
8. Clean the filter under running water, and if damaged replace it.
N.B: It can only be put back in the appliance when completely dry.
9. If there is one inside the collection tank, clean the foam block float with a damp cloth
(Fig.14).
10. Refit all the parts.
