OK, so what is this time it David ?
LOADING / FILLING Rested Sprayers.
What do you mean?
You would not believe the number of calls that we get during Spring, and through the season, generally from frustrated sprayer operators, who have filled up their sprayer with water and chemical ready to spray and then found that the sprayer has leaks or just won’t work.
ALL sprayer operators really do need to check over their sprayer for fitness of purpose, ----before they even put water in the tank.
This is following what should have been a good rinsing and cleaning / decontamination before Autumn / Winter storage,
This process helps to keep seals and O-rings and diaphragms in better shape ready for the OFF
- Firstly check tightness of all connections of hoses & diaphragms, lid seals etc
- Check that the tank is clean & free from grit or bits of grass.
- Check and clean any in line filters in hoses, or shut off valve handles, or in nozzle mounts such as with anti- drip valves/ nozzle filters.
- Check that the actual spray nozzle is the appropriate type for the intended spray operation, & that it is not damaged.
- Refer to your specialist supplier for advice on this key element for optimisation of accuracy, efficacy and safety.
- Set the pressure relief valve (if fitted) to 2 or 3 bar, or to the highest setting.
If your machine has none of these features, consider using a Flow Control Valve to ensure more consistent & accurate application rates.
NOW PART LOAD WITH WATER and test the sprayer, spray pattern and output.
Calibrate the sprayer.
IF OK put the requisite chemical into the partially filled tank and top it up.
Now Enjoy your Spray Day
