COMAC OPTIMA 85B - Starting Work and Operating Modes; Initiating Machine Operation; Understanding Work Functions

STARTING WORK
To start working, do as follows:
1. Make all the checks listed in “PREPARING TO WORK”.
2. Sit in the driver's seat, to adjust the driving position read paragraph “USER SEAT ADJUSTMENT”.
3. Move the main switch (1) to position “I” and turn the key a quarter turn clockwise (Fig. 1).
4. When the display comes on, three screens appear in sequence.
• The rst screen displayed indicates the logo of the manufacturer of the machine.
• The second screen displayed indicates the name of the machine.
• The third screen displayed (Fig. 2) indicates the characteristics of the machine's programming.
• The forth screen displays (Fig. 3) identies the work panel.
5. Select the movement direction using the selector switch (2) (Fig. 4).
6. Select one of the following work functions (Fig. 6) by means of the knob (3) (Fig. 5):
A. Transfer
B. Drying
C. Scrubbing with drying
D. Scrubbing without drying
7. Press the forward movement pedal (4) (Fig. 7) to begin moving the machine.

Transfer function:
The machine can be moved from one work area to another with the selector switch in transfer mode. The only main actuator active is that of the traction hub
motor.
Drying function:
With the selector in drying mode it is possible to dry the previously washed portion of the oor. The main actuators active are those of the traction hub motor
and the vacuum motor. When the drive pedal is pressed, the squeegee is brought into working position (in contact with the oor) and the vacuum motor will
start working in full working order. If the machine is stopped and the drive pedal is released during the operation, the squeegee body will remain in contact
with the oor for a few seconds, after which it will raise up from the ground to go back to its rest position. For all these phases the vacuum motor will continue
to operate, only after a few seconds that it has returned to its work position will it switch o󰀨, this is to allow the motor to collect all the liquid in the vacuum
hose. During these phases, the symbol of the vacuum motor on the instrument panel display will blink, and it will only stop when the squeegee is in its rest
position and the vacuum motor is o󰀨. If reverse is carried out with this program active, the squeegee will move to the rest position, the vacuum motor will
keep working for a pre-set time and then it will switch o󰀨.
Scrubbing with Drying function:
With the selector in the scrubbing with drying mode it is possible to both scrub and dry the oor at the same time. The main actuators active are those of the
traction hub motor. brush head gearmotors and vacuum motor. When the drive pedal is pressed, both the brush head and the squeegee will move to the
working position, and as soon as it is in contact with the ground the brush head gearmotors and the vacuum motor start working in full working order. If the
machine stops and the foot pedal is released during the operation, the brush head body will start to rise to return to the rest position, and after a period of
time the gearmotors will switch o󰀨. The squeegee body will stay in contact with the oor for a few seconds, after which it will raise up from the ground and
return to its rest position. For all these phases the vacuum motor will continue to operate, only after a few seconds that it has returned to its rest position will
it switch o󰀨, this is to allow the motor to collect all the liquid in the vacuum hose. During these phases, the symbol of the vacuum motor on the instrument
panel display will blink, and it will only stop when the squeegee is in its rest position and the vacuum motor is o󰀨. If reverse is carried out with this program
active, the squeegee will move to the rest position, the vacuum motor will keep working for a pre-set time and then it will switch o󰀨.
Scrubbing without drying function:
With the selector in scrubbing without drying mode, it is possible to scrub the oor without vacuuming the detergent solution applied. The main actuators
active are those of the traction hub motor and the brush head gearmotors. When the drive pedal is pressed, the brush head will move to the working position,
and as soon as it is in contact with the ground the brush head gearmotors start working in full working order. If the machine stops and the foot pedal is
released during the operation, the brush head body will start to rise to return to the rest position, and after a period of time the gearmotors will switch o󰀨.
The drying without scrubbing operation should only be carried out if the machine was previously used to carry out a
scrubbing without drying operation.
