Operating Instructions
•
Ensure that the hose is securely attached to the sprayer and the lance and the locking nut
are tight.
•
Check that the liquid which you intend to use is suitable (see the spraying chemical
section).
•
Fill the container to the desired level taking care not to exceed the maximum fill mark.
•
Screw the pump firmly home to ensure an airtight seal.
•
Operate the pressure release valve manually by pulling the blue knob upwards to ensure it
is functioning correctly.
•
Release the pump handle by pressing down and turning anti-clockwise.
•
Pump to pressurize the container.
•
When the correct operating pressure has been reached, the pressure release valve will vent
to discharge excess air.
•
The container is adequately pressurized and does not require further pumping.
Trigger Operation
•
The trigger mechanism has been designed to allow for two modes of operation, either
intermittent or continuous.
Intermittent Operation
•
Depress trigger to operate and release it to stop spraying.
Continuous Operation
•
While depressing trigger push forward with the thumb to hold in the lock on position.
•
The sprayer will now continue to operate without any further finger pressure, so preventing
fatigue.
•
To turn off the sprayer pull back the level and release.
•
Aim the spray nozzle towards a test area, squeeze the trigger on the lance and adjust the
nozzle to the desired degree of fineness by twisting the nozzle from mist through coarse
spray to jet.
•
Do not undo the nozzle too far or leakage will occur from the back of the nozzle.
•
If the nozzle continues to spray or drip after the trigger has been released, it is because
there is air in the discharge system (lance, handle trigger or hose).
•
Purge the system by turning the nozzle to jet and operating the trigger on the lance on and
off in short bursts until the liquid shuts off cleanly.
•
Collect any chemicals in a separate container and use later.
•
To keep spraying a few pumps at infrequent interval are all that is required.
•
After use and before storage release the pressure from the container by pulling the blue
knob of the pressure release valve upwards.
•
If the sprayer has been used with chemicals, discard safely any unused solution after use.
•
Add a little detergent and some warm water (not hot) to the sprayer.
•
Re-assemble the sprayer and spray some of the contents through.
•
Repeat with the clean, cold water.
•
Check that the nozzle assembly is free from sediment.
•
If necessary, repeat the process until the sprayer is clean.
