- Preparation of the solution to be sprayed:
Liquid-based product (to be diluted in water):
fill the tank with 1 to 2 litres of water, pour in
the dose of liquid product, then fill up with the
required quantity of water.
During use
- Manually screw the pump on the reservoir
(Fig. 14).
- Pump to pressurise until the valve operates
(until a blast of air is released) (Fig. 15).
- Pressurise the sprayer exclusively with its pump.
- Spray by pressing the handle switch (Fig. 16).
After use/ Cleaning
After each use:
- Eliminate any residual pressure that may
remain in the apparatus operating the safety
valve, by pushing it, or by spraying until there is
no more pressure.
- Avoid risks of pollution by recovering any
unused product and its packaging.
- Wash your hands and face with clean water
after using the sprayer.
- Never store the sprayer pressurised.
- Never store the treatment agent inside the sprayer.
- Store the sprayer in a closed location out of the
reach of children.
- Clean the handle filter and the suction filter in
the reservoir if present in the sprayer. (Fig. 19)
- If you spray until there is just air in the spray:
eliminate residual pressure remaining in the
sprayer by operating the safety valve (Fig. 17)
or by spraying until there is no more pressure.
The residual volume of liquid is less than 250 ml.
- Before storing and before any other use
with another treatment agent, perform a
rinsing operation, i.e. put 1 litre of water into
the reservoir for dilution, mix thoroughly
and operate the apparatus to rinse all of the
apparatus' components.
This rinsing operation must be carried out
without removing any of the accessories used
during the treatment. The rinsing mixture must
not be emptied into a sewer but must be sprayed
outside on the land that has already been
treated.
- Repeat the operation several times before the
winter period.
- If there is still some unused treatment product
left, eliminate any residual pressure remaining in
the apparatus by operating the safety valve
(Fig. 17). Recover any possible excess of product
and rinse the sprayer again as indicated above.
- Before using again, even if it is used again
immediately, with the same treatment product
or a different one, repeat the rinsing operation
3 consecutive times and check that the sprayer
works properly (especially the safety valve).

MAINTENANCE / SERVICING

Periodically, on re-use after the winter period
and several times per season, grease all the
joints (with silicone grease for sprayers) and
check that the sprayer is working properly
(especially the valve).
- Clean the nozzle and the nozzle holder (Fig. 18)
- Clean the lance filter (Fig. 19)
- Disassemble the pump (Fig. 20)
- Grease or replace the valve and the seals
(Fig. 20 A, B, C, D)
- The sprayer is equipped with a reservoir which
is resistant to UV radiation.
