g) Operate the lever (26) on the lance (13) to achieve the required spraying angle (from an
empty cone to a needle-point jet). The adjuster (24) can be used to fix the preferred position
for spraying. We recommend this is done while spraying with the lance into the tank to avoid
wasting chemicals.
h) The flow rate of the sprayed liquid depends on the operating pressure, the nozzle (27) used
(the 1.5 mm Ø nozzle is supplied as standard with the appliance) and the adjustment of the
spray angle. Refer to the table below for information on which nozzle to use for a job (note
that the maximum flow is indicated, i.e. corresponding to a needle-point spray angle).
WARNING
• Follow step c) each time the tank is emptied of liquid to ensure the appliance will prime
quickly.
• We recommend checking the pump oil level after the first few hours of operation and to top
it up if necessary as indicated in the “PRELIMINARY PROCEDURES” section.
5. SWITCHING OFF
CAUTION
• Always check that there are no moving parts on the appliance and there is no pressurised
liquid in the hoses after the following instructions for switching off have been
completed.
• When switching off the appliance and leaving it to cool down, take care that:
- the appliance is not left unattended in the presence of unsupervised children, elderly or
disabled people.
- the appliance is in a stable position and not at risk of falling over.
- the appliance is not in contact with inflammable materials, or in their immediate
vicinity.
a) Eliminate the delivery pressure as instructed in point c) in the “Spraying” section.
b) If the appliance is fitted with an electric motor, operate both the switch on the electric motor, if
any, and the universal circuit breaker on the socket that the appliance is connected to, by putting
them both in position “0” and remove the plug from the power outlet. For appliances fitted
with a combustion engine, follow the instructions for switching off the same in the engine’s
operating and maintenance instructions and then disconnect the spark plug.
c) Put the lance lever (26) in position “ON” so that any residual pressure is discharged.
