MACHINE PREPARATION
1. HANDLING THE MACHINE
The machine is delivered packed, on a pallet. A forklift or other lifting means (hoist)
of a suitable capacity should be used for handling purposes.
If the machine is delivered without any packaging, it should be handled with lifting
means of a suitable capacity (hoist, bridge crane), using the special lifting plates
supplied with it; fix them to the hooks on the machine itself.
The use of any other lifting system will invalidate the warranty in relation to any
damage that may result.
ATTENTION: only lift when the debris container is empty.
2. HOW TO UNPACK THE MACHINE
To remove the packaging, proceed as follows:
1. cut the straps
2. remove the metal points at the base of the packaging
3. remove the cardboard
Dimensions of the packaging (in cm) and weight of the packed machine without batteries:
CS 80B 203x128x162 780kg
CS 80D 203x128x162 820kg
CS 90B 238x152x164 790kg
CS 90D 238x152x164 850kg
3. EARTH CONNECTION
Use a hammer to remove the wooden wedges blocking the front wheels.
Use a hammer to remove the front crossbar of the pallet, to create a ramp.
Open the motor cover and bring the hydrostatic drive valve lever (1) to the vertical
(idle) position as otherwise the machine cannot be moved. (On the battery-operated
version the lever is in the lower part of the pump.)
Disengage the parking brake.
Close the cover and push the machine forwards so it slides down the ramp.
Bring the hydrostatic drive valve lever back to the horizontal (running) position
(clockwise or anticlockwise) so the machine can operate.

WORK
MACHINE START-UP, VERSIONS 80B-90B
Comac sweeping machines should only be used by trained, authorised operators,
and only when the machine itself is in perfect working order. Faulty sweeping
machines must be taken out of service immediately.
Before carrying out any type of work:
1. check the parking brake is disengaged
2. turn the key to position I (clockwise)
3. check the battery charge is sufficient for carrying out the planned work
ATTENTION: To avoid any permanent damage to the batteries,
it is essential to avoid their total run-down. When the run-down
buzzer sounds, the machine must be switched off (maintaining
just the forwards function so it can reach the recharge point).
4. Open the hatch of the debris hopper (green indicator light ON).
5. On the side instrument panel, activate the lever to lower the central brush,
and the lever for the side brush (only for cleaning near pavements, walls, etc.).
6. Activate the suction (left-hand lever).
7. Press the pedal command to move, and adjust the machine speed according
to the quantity of dust and dirt on the floor.
8. If you need to transfer the machine to another area, you are advised not to
use the brushes (raise them).
ATTENTION: the machine is fitted with a micro-switch under the
seat to indicate the presence of an operator on board; this switch
stops the machine moving if the operator is not correctly seated.
INITIAL START-UP AND USE OF THE MACHINE, VERSIONS 80D – 90D
Move the accelerator lever until it is in the minimum position.
Start the motor by means of the start-up key, bringing it to the heating position (I).
Wait about 6 seconds, until the glowplug indicator light (11) switches off.
When the indicator light is OFF, turn the key to the start position.
When the motor switches on, release the key.
After an initial heating phase (see “after motor start-up“), bring the motor to a speed
of about 2000rpm, using the accelerator lever.
The machine is now ready to work.
Observe the warnings given in the Use and Maintenance booklet of the motor
for start-up operations (motor start-up).
MACHINE DIRECTION
The choice of direction when using the machine does not involve any switches or
levers, but is implemented via the pedal command: pressing the right-hand pedal the
machine moves forwards, while the left-hand pedal enables reverse movements.
14
WORK
SUCTION ACTIVATION
The machine works in normal conditions with the hatch open, as the dirt is picked up
by the brush and sucked into the debris hopper (left-hand lever - 1).
Pressure on the hatch lever will illuminate the green indicator light ("hopper open")
on the instrument panel, so the dirt can be collected.
Turning the lever (1) anticlockwise, the air flow in the hopper is interrupted.
Press the filter shaker switch on the instrument panel to activate the filter shaker
motor and free the dirt captured by the filter itself.
To maintain effective suction via the filter shaker, clean the filter every 20-
30 minutes and always before emptying the debris hopper.
NB: do not activate the filter shaker when the suction is enabled.
ATTENTION: avoid prolonged operation of the filter shaker motor.
Turn off the suction by means of the lever (1) when you are about
to work on wet or damp surfaces, to avoid ruining the filter.
USING THE SERVICE OR PARKING BRAKE
Use the service brake whenever you want to slow down or stop the machine
movement.
Pull the parking brake when you want to park or stop on a sloping surface.

15
WORK
EMPTYING THE DEBRIS HOPPER
When the machine begins to leave behind clear traces of dirt, this means the hopper
is full and needs emptying.
ATTENTION: before emptying the debris hopper, close the
hatch by means of the lever on the side instrument panel, and
check there is nobody within the machine's working radius.
To raise the debris hopper, proceed as follows:
1. close the hatch by pushing the lever (1) upwards
2. push up the lever that raises the debris hopper (2) until the required height is reached
3. move next to a debris hopper
4. push the hatch lever (1) down, so the hatch opens to empty the hopper
ATTENTION: when the debris hopper is raised, move the
machine very slowly - maximum speed 1km/h.
Only empty the hopper when the machine is on an even surface.
Do not activate the filter shaker when the hopper is raised.
After emptying, pull the hatch lever down to close the hatch.
For safety reasons, the hopper lowering operation is only possible if the green
button (1) on the front instrument panel is pressed (with the right hand) at the same
time as the hopper lowering lever (2) is pushed down.
After bringing the hopper back to the working position, open the hatch again by
pushing the lever (3) upwards.
