7.14  SPECIFIC INSTRUCTIONS FOR THE 

USE OF MODEL AC 230V

The AC 230V  machine may be turned on only if the 

voltage indicated on the tag corresponds with the 

available voltage and that the electrical outlet is 

grounded (earthed).

Do not damage the feed cable; do not crush or pull 

on it.  

•

 ATTENTION  Make sure that the power cable does 

not come into contact with the rotary brushes.

•

 ATTENTION  - The AC 230V machine has parts, 

which are connected to the current; contact with 

these could cause grave injuries or even death. 

- Before executing any type of operation on the ma-

chine always disconnect it from the electrical source.

- Never touch electric cables that are defective or 

worn.

- Before gaining access to the electrical system it is 

always necessary to disconnect the machine from 

the electrical source by removing the plug from the  

socket-outlet.

- In the case of defective, damaged, or cracked electric 

cables, replace immediately with authentic replace-

ment parts. 

- The network of connections must be protected from 

water spray.

- The patch cord for the connection of the machine 

to the mains power must conforms to current 

safety rules.   

- The electrical system to which the machine is con-

nected must be equipped with a cutout box.

- It is absolutely forbidden to use the machine in prox-

imity to swimming pools or stretches of water.

•

 EMERGENCY SITUATIONS

In case of emergency:

- Immediately disconnect the machine from the 

power mains.

- Immediately apply proper first-aid.

If an accident should occur the machine must not be 

put into operation until a technician authorized by 

the manufacturer has examined it.

8. MAINTENANCE 

MAINTENANCE INFORMATION

•

 Switch OFF the ON-OFF main switch, and Discon-

nect the Anderson connector of the battery wiring 

from the Anderson connector of the machine wiring 

(Foto B-17)(Foto B-18).

☞

 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 authorized service centers or by special-

ized 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 plugs of the tanks open (only while the ma-

chine is not being used) so that they can dry and thus 

prevent the formation of foul odors.

8.2 

SOLUTION FILTER CLEANING

Remove the transparent cap (Foto E-36) then remove 

the metal strainer.
