completely by letting the pump work and keeping the spray lever pressed.
This operation is useful to clean the hydraulic circuit of the machine, including
the pump, the couplings, the nozzle.
2. After each use, switch off the motor and the pump, then close the security
valve of the air outlet.
3. Periodically clean the water filter, removing it from the machine and rinsing it
under water.
4. Periodically check and clean the filter of the vacuum motor, which is located
between the 2 tanks.
5. Eliminate the lime that, in the long run, deposits in the hydraulic circuit, by
putting a special anti-lime chemical in the solution tank and letting it work from
some hours. Use the same products used for dishwashers. Empty and then
rinse the solution tank. This operation should be done every 6-8 months.
6. Periodically bring the machine to a technical service point, to check the
correct working of all the parts subject to wear. In particular: pump, vacuum
motor and compressor. There are some parts, like carbon brushes, bearings,
and so on, which must be replaced on time to avoid serious damages to the
components upon which they are assembled. These damages cannot be then
covered by warranty.
7. Periodically drain (every 2-3 months) the air tank from condensate that may
originate during the normal working.
ATTENTION:
This operation must be done with the compressor completely
empty and with the machine switched off.
