Cleaning The Brush Head Body Brushes; Cleaning The Recovery Tank - COMAC Innova Comfort Use And Maintenance Manual

CLEANING THE BRUSH HEAD BODY BRUSHES

Careful cleaning of the brush guarantees better cleaning of the floor as well as a longer brush head gearmotor lifespan.
To clean the brush on manual machine versions, proceed as follows:
1. Stand on the left side of the machine.
2. Turn the brush in increments so that the button on it is released from the coupling spring in the brush-holder plate (Fig.14).
N.B.: Image 14 indicates the direction of rotation for coupling the left brush; the right brush must be turned in the opposite direction.
3. Repeat the operations described for the right-hand front brush as well.
4. Clean the brush under a stream of running water to remove any impurities from its bristles. Check the wear status of the bristles and replace
the brushes if they are excessively consumed (the bristles' protrusion must not be less than 10 mm; this distance is indicated on the brush by
the yellow band). To replace the brushes, refer to "ASSEMBLING THE BRUSH HEAD BODY BRUSHES" on page 19.
N.B.: you are advised to invert the right and left-hand brushes every day.
ATTENTION: If the brushes are not new however, and have deformed bristles, it is better to reassemble them in the same position (the
right-hand one on the right, and the left-hand one on the left), to prevent the different inclination of the bristles producing an overload on
the brush motor as well as excessive vibrations.
To clean the brush on automatic machine versions, proceed as follows:
1. Unhook the tank rotation stop lever (14) (Fig.15) and turn the recovery tank to its maintenance position (Fig.16).
2. Connect the battery connector to the machine's main system connector (Fig.17).
3. Rotate the recovery tank into the working position (Fig.18). Use the lever (14) to block rotation (Fig.19).
4. Sit on the driver's seat.
5. Insert the key (15) into the main switch on the control panel. Bring the main switch to the "I" position, making a quarter turn clockwise with
the key (15) (Fig.20).
6. Select the "TRANSFER" program, then turn the knob (16) on the control panel (Fig.21) as far as icon (A) (Fig.22).
N.B.: in this way, both the brush head body and the squeegee body will move to their idle position.
7. When button (17) on the control panel (Fig.23) is pressed for the first time, the confirmation request symbol will appear on the control display
(Fig.24).
8. Pressing the button (17) again will activate the brush release function.
N.B.: Once the release sequence has been activated, it is not possible to activate other functions or move the machine.
CAUTION: During this operation, check there are no people or objects near the brush.
9. Clean the brush under a stream of running water to remove any impurities from its bristles. Check the wear status of the bristles and replace
the brushes if they are excessively consumed (the bristles' protrusion must not be less than 10 mm; this distance is indicated on the brush by
the yellow band). To replace the brushes, refer to "ASSEMBLING THE BRUSH HEAD BODY BRUSHES" on page 19.
N.B.: you are advised to invert the right and left-hand brushes every day.
ATTENTION: If the brushes are not new however, and have deformed bristles, it is better to reassemble them in the same position (the
right-hand one on the right, and the left-hand one on the left), to prevent the different inclination of the bristles producing an overload on
the brush motor as well as excessive vibrations.

CLEANING THE RECOVERY TANK

To clean the recovery tank, proceed as follows:
1. Release the recovery tank drainage tube at the back of the machine from the retainers (Fig.1), unscrew the cap and place it on the ground
(Fig.2).
2. Grip the handle on the back of the recovery tank cover and remove it (8) (Fig.9).
3. Rinse the inside with a jet of water, if necessary use a spatula to remove the sludge that has accumulated at the bottom of the tank.
4. Repeat the operations in reverse order to reassemble all the parts.
