gearmotor lifespan. To replace the brush, proceed as follows:
1. Take the machine to the maintenance area.
2. Make sure the machine has been secured (see the section titled “
”).
CAUTION
: users are advised to always wear protective gloves, to avoid the risk of serious
injury to hands.
NB
: the place designated for this operation must comply with current environmental protection
regulations.
3. Go to the front of the machine.
4. Replace the worn brush with a new one.
5. Press the brush-holder plate retainer (1) and simultaneously rotate the brush in the direction
shown in the image (
Fig.1
).
ATTENTION
:
Fig.1
shows the rotation direction of the left-hand brush.
6. When brush rotation is prevented, turn until the button on the brush is disengaged from the
coupling spring on the brush-holder plate.
7. Repeat the same operation for the right-hand brush.
REPLACING THE BRUSH HEAD BRUSH (60BT VERSIONS)
REPLACING THE ABRASIVE PAD (50BTO VERSIONS)
Ensuring the good condition of the abrasive pad will guarantee better floor cleaning results, and will
extend the service life of the brush head motor. To replace the abrasive pad, proceed as follows:
1. Take the machine to the maintenance area.
2. Make sure the machine has been secured (see the section titled “
”).
CAUTION
: users are advised to always wear protective gloves, to avoid the risk of serious
injury to hands.
NB
: the place designated for this operation must comply with current environmental protection
regulations.
3. Go to the front of the machine.
4. Replace the worn pad with the new one. With the brush head in the raised position, slide the
abrasive pad into the housing under the brush head, pressing it until it is firmly attached to it (
Fig.1
).
REPLACING THE CYLINDRICAL BRUSHES (50BTS VERSIONS)
The good condition of the brush guarantees better cleaning of the floor, as well as a longer brush head
gearmotor lifespan. To replace the brush, proceed as follows:
1. Take the machine to the maintenance area.
2. Make sure the machine has been secured (see the section titled “
”).
CAUTION
: users are advised to always wear protective gloves, to avoid the risk of serious
injury to hands.
NB
: the place designated for this operation must comply with current environmental protection
regulations.
3. Go to the front of the machine.
4.
With the brush head raised from the floor, turn the knobs (1) that hold the left lateral carter (2) in
place anti-clockwise (
Fig.1
).
5. Remove the left lateral carter (2) (
Fig.2
).
6. Replace the worn brush with a new one. Insert the brush into the tunnel, taking care to make
sure that the gearmotor's drive shaft enters the slit in the brush itself.
7. Repeat the previously described operations for the right-hand side as well.
NB
: In order to be installed correctly, the brushes must form an X when viewed from above in
the forward direction of movement (
Fig.3
).
REPLACING THE SQUEEGEE BODY RUBBER BLADES
Ensuring the good condition of the squeegee body rubber blades guarantees better floor cleaning and
drying results, as well as a longer service life for the vacuum motor. To replace the squeegee body
rubber blades, proceed as follows:
1. Take the machine to the maintenance area.
2. Make sure the machine has been secured (see the section titled “
CAUTION
: these operations must be carried out using protective gloves to avoid any possible
contact with the edges or tips of metal objects.
3. Remove the vacuum tube (1) from the vacuum nozzle on the squeegee body (
Fig.1
).
4. Completely unscrew the knobs (2) in the squeegee body pre-assembly (
Fig.2
).
5. Remove the squeegee body from the slits in the squeegee connector (
Fig.3
).
6. Remove the rear rubber-pressing blade by releasing the retainer (3) on the back of the squeegee
(
Fig.4
).
7. Remove the rear rubber blade (4) from the squeegee body (
Fig.5
).
8. Completely unscrew the knobs (5) in the squeegee body pre-assembly (
Fig.6
).
9. Remove the front rubber blade (7) from the inside of the squeegee (
Fig.7
).
10. Repeat the operations in reverse order to reassemble all the parts.
NB
: before using the machine, remember to adjust the squeegee body (see
).
NB
: you are advised to replace both squeegee body blades in order to ensure good results when
drying the floor.
ADJUSTMENT INTERVENTIONS
ADJUSTING THE SQUEEGEE BODY RUBBER BLADES
Careful adjustment of the squeegee body rubber blades guarantees better cleaning of the floor.
To adjust the squeegee body blades, proceed as follows:
1. Make sure the machine is in a safe condition (see “
ATTENTION
: these operations must be carried out using protective gloves to avoid any
possible contact with the edges or tips of metal objects.
2. Stand at the back of the machine.
Adjusting the height of the squeegee body:
3.
Adjust the height of the rubber blade in relation to the floor by loosening or tightening the knobs
(1) (
Fig.1
).
NB
: Figure 1 indicates the rotation direction for decreasing the distance between the squeegee
support and the floor. This distance can be increased by turning it in the opposite direction.
NB
: by decreasing the distance between the squeegee support and the floor, the rubber blades
present in the squeegee body move closer to the floor.
NB
: the right-hand and left-hand knobs must be rotated the same number of times, so that the
squeegee is parallel to the floor when it is working.
NB
: make sure the adjustment is correct by looking at the instrument (2) on the squeegee body
(
Fig.2
).
