Periodic Maintenance; Post-Scrubbing Operations; Maintenance Information - Comet CRS 90 BT Manual De Instrucciones

Prepare the machine as previously described.
First set of operations:
Select the forward direction using the direction lever.
Insert and turn the key.
Activate the brush motor and the detergent solution
supply.
Lower the brushes.
Use the detergent adjustment lever to regulate the
solution outlet flow (depending on advancement
speed).
Lightly press the advancement pedal and check that
the brushes and solution feed system are working.
Fully depress the accelerator to increase the work
speed.
Adjust the maximum advancement speed and the de-
tergent solution flow as required.
The steering wheel is similar to a car steering wheel: it
can be used to turn the machine around itself by stee-
ring all the way to one side.
• During these operations, the rear of the machine
moves slightly outward: reduce the speed to avoid
brusque direction changes and impacts against walls
or other objects.
Allow the detergent solution to work on the dirt ac-
cording to what is indicated in the information relative
to the detergent used.
Second set of operations:
Follow the steps described in the previous section
"Direct Scrubbing" (7.8.3).

8.9 PERIODIC MAINTENANCE

Remove and wash the squeegee
Drain the recovery tank
Drain, rinse with clean water or sanificate the recovery tank
Charge the batteries
Check the acid level in the battery cells (if batteries are not
maintenance-free)
Remove brushes and check for brush wear, foreign bodies and wrapped belts
Verify the machine general conditions.
Verify that suction hose and conduct are free from obstructions
Check the wear of the squeegee rubber blades
Open and clean the solution water filter
Clean the brush plate, squeegee support and squeegee
Check the lifting/lowering of the brush plate.
Check the lifting/lowering of the squeegee.
Grease the moving parts.
Check the control cable for the opening of the solution water tap.
Verify the security devices ( emergency switch, mechanical or electromechani-
cal brake, operator safety switch, etc).
Descale water hoses.
To avoid damage to the surfaces being treated, the
brush motor will stop automatically about 2 seconds
after the advancement pedal has been completely
released.
When moving in reverse, the squeegee will lift and
suction will be deactivated automatically. After
changing direction (forward direction), the squeegee
and the suction will automatically return to
their previous condition.
☞ Never use the machine without the detergent
solution: the floor might be damaged

7.8.5 POST-SCRUBBING OPERATIONS

Lift the brush unit and turn off the brush motor.
After having completely dried any traces of water
on the surface, wait a few seconds and then lift the

Move to a suitable location to drain the tanks (as de-
scribed in 7.4 and 7.5).
Empty and clean the tanks (see sections 7.4 and 7.5).
Turn off the machine using the key and remove it from
the control panel.
If necessary, charge the battery (see the relative sec-
tion)..
