Maintenance Information; Tanks; Suction Hose; Squeegee - Comet Spa CRS 75 BT Manual De Instrucciones

R Plus is equipped with electric actuators for the
automatic lifting/lowering of the brush group unit
and of the squeegee.
The lifting/lowering of the brush group unit can be ef-
fected through the selector positioned on the control
panel (Photo M - 5) and takes place simultaneously
to the switching on/off the brush motor; the lifting/
lowering of the squeegee can be effected through the
selector positioned on the control panel (Photo M - 4)
and takes place simultaneously to the switching
on/off the suction motor.
When moving in reverse, the squeegee will lift au-
tomatically in order to avoid to damage itself. After
changing direction (forward direction), the squee-
gee will automatically return to their previous con-
dition.

8. MAINTENANCE INFORMATION

Turn the key, remove it from the control panel and
disconnect the battery from the machine wiring.
All work on the electrical system as well as all main-
tenance and repair operations (especially those not
explicitly described in this manual) should be carried
out only by authorised service centres or by special-
ised technical personnel who are experts in the sector
and in the pertinent safety regulations.
Performing regular maintenance on the machine, and
carefully following the manufacturer's instructions,
is the best guarantee for obtaining the best perfor-
mances and extended machine service life.
8.1

TANKS

Drain the two tanks as described in the relative sec-
tions.
Remove any solid dirt by filling and draining the tanks
until all dirt has been eliminated: use a washing hose
or similar tool to do this.
Water hotter than 50°, a high-pressure cleaner
or excessively powerful sprays may damage the
tanks and the machine.
Leave the covers of the tanks open (only while the
machine is not being used) so that they can dry and
thus prevent the formation of foul odours.
8.2

SUCTION HOSE

Detach the suction hose from the squeegee.
Pull out the suction hose from its connection hole
placed in the recovery tank.
Now you can wash the hose and remove any obstruc-
tions.
After the cleaning, firmly insert again the suction hose
inside connection hole placed in the recovery tank.
Firmly insert the hose on the squeegee body.
8.3

SQUEEGEE

Do not handle the squeegee with bare hands: wear
gloves and any safety clothing needed to carry out
the operation.
Detach the squeegee from the machine and clean it
under running water using a sponge or a brush.
Check the efficiency and the wear on the strips in con-
tact with the floor. They are designed to scrape the
film of detergent and water on the floor and to isolate
that portion of the surface to enhance the vacuum of
the suction motor: this ensures that the machine will
dry very efficiently. Working constantly in this manner
tends to round or to deteriorate the sharp edge of the
strip, thus reducing drying efficiently. This is why the
squeegee strips must be replaced.
To replace the worn straps, follow the instructions in
the relative section. Turn the straps around to wear
down the other sharp corners or to install new ones.
8.4

ACCESSORIES

Remove and clean the brushes or the scraper disks.
To avoid damaging the floor and the machine,
carefully check if foreign matter, such as metallic
parts, screws, chips, cords or similar items, has be-
come jammed.
Check that the brushes are flat as they work on the
surface (check for any irregular wear on the brushes
or on the abrasive disks). If necessary, adjust the slant
of the action on the floor.
Use only the accessories recommended by the manu-
facturer: other products may reduce operating safety.
8.5

CLEANING SOLUTION FILTER

Make sure that the detergent solution tank is empty.
Check and clean the solution filter located in the
lower front part of the machine. Clean with running
water if necessary and check that the detergent solu-
tion is being delivered on the brushes.
Fully tighten the filter to prevent leaks during opera-
tion.
8.6 MACHINE BODY
Use a sponge or a soft cloth to clean the exterior of
the machine and, if necessary, a soft brush to elimi-
nate tough dirt. The machine's shockproof surface
is rough to make it harder to see scratches caused
during use. However, this does not make it easier to
remove tough stains on the surface. Steam machines
can be used but it's prohibited to use hoses with run-
ning water or a high-pressure cleaner.

8.7.1

PB-ACID

Carry out maintenance operations in accordance with
the manufacturer's instructions and with all the other
instructions provided in this manual.
Exposing the element plates (not completely im-
mersed in the acid solution) will lead to rapid oxida-
tion and irreparably reduce the element's operating
