Maintenance / Servicing - Hozelock Pulsar Plus Manual De Instrucciones

OPERATION
- Follow the manufacturer's instructions for the
treatment agents (dosage, application method,
rinsing).
- Only prepare the quantity of agent that is
strictly necessary and for one application.
- Dosing is easy due to the graduation scale on
the reservoir. The transparent tank allows full
visibility of the liquid level.
- Preparation of the solution to be sprayed:
a) Powder product (soluble or wettable):
prepare the solution in a bucket before
decanting it into the reservoir through the filling
hole.
b) 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 (Fig. 15).
During use
- Depending on the apparatus, manually screw the
filling cap or the pump on the reservoir (Fig. 16).
- Pump to pressurise until the valve operates
(until a blast of air is released) (Fig. 17).
- Pressurise the sprayer exclusively with its pump.
- Spray by pressing the handle switch (Fig. 18).
- Adjust the jet by turning the nozzle in both
directions (Fig. 19, depending on the model.
Fig. 19b Release the trigger before rotating
nozzle to different settings. Ensure the arrow is
aligned with the number before spraying. Failure
to do so may result in leaks).
- Depending on the model: The regulator
provides a constant spraying pressure.
Therefore:
Spraying takes place at the pressure indicated
on the regulator, even if the sprayer is set to a
higher pressure than this. Spraying stops when
the sprayer pressure falls below the pressure
indicated on the regulator. Pump again to
pressurise the apparatus.
- A range of accessories are available to ensure
treatments suitable for different uses (weed
control booms, telescopic lance, weed control
cover, etc.) (Fig. 14).

After use/ Cleaning
After each use:
- Eliminate any residual pressure that may
remain in the apparatus operating the safety
valve, by pushing it (Fig. 20), 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. 22)
- If you spray until there is just air in the spray:
eliminate residual pressure remaining in the
sprayer by operating the safety valve (Fig. 20)
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.
- Rinsing for models equipped with 1 bar
pressure regulator: add 1 litre of water to the
sprayer, pressurise and spray into a suitable
container until all the liquid has been evacuated
and air comes out of the nozzle. To discharge the
remaining pressure in the sprayer, use the safety
pressure release valve (Fig. 20).
- If there is still some unused treatment product
left, eliminate any residual pressure remaining in
the apparatus by operating the safety valve
(Fig. 20). 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. 21)
- Clean the lance filter (Fig. 22)
- Disassemble the pump (Fig. 23)
- Grease or replace the valve and the seals
(Fig. 23 A, B, C, D)
- The sprayer is equipped with a reservoir which
is resistant to UV radiation.
