Commissioning & decommissioning

Press the pump handle down and then turn it to the left. You can now remove the pump and fill the spray liquid up to the maximum mark on the device. Please pay attention to the exact instructions of the spray manufacturer. Now you can mix the liquid well and screw the pump back on. Next, you have to pump until the red color mark appears on the safety valve. When this happens, press the hand lever to start the spraying process. If you release the hand lever, the spraying process is interrupted. If you want to open the container again, please first pull on the safety valve to release the pressure.

Please clean the syringe carefully after each use. To do this, simply open the pressure-free container and rinse and clean it with clean water. Please do not use aggressive cleaning agents such as cold cleaners or thinners.

The SOLO 425 is pre-assembled except for the lever. And you can attach this to the right or left, as you wish. The lever of the 425 pressure sprayer is pre-assembled on the left at the factory → when looking at the container label. When assembling the lever, the holding tube (b) of the lever must point upwards and backwards. To put the device down, the pump lever © in the holding tube (b) can be turned upwards and the spray tube can be hooked into the two clamps (d). When you want to work with the pressure sprayer again, turn the pump lever © in the holding tube (b) back down.

The spray pipe is attached to the hand valve by tightening the union nut (e).

To regulate the quantity, the spray pressure can be set to different levels. These are approximately in the range of 1 to 4 bar.

If you want to treat shrubs or trees, the nozzles with a hollow cone spray pattern (f) are best. For normal surface treatments, we recommend the flat jet nozzles (g).

The pressure is adjusted before filling the spray liquid by turning the adjustment cap (h) above the marking on the air vessel.

Important: Please do not fill the container beyond the maximum mark.

Now use quick lever movements to prime the pump and open the shut-off valve by operating the hand lever. Only the spray liquid is sprayed through the nozzle through the opening. When you release the hand lever, the spray jet is immediately interrupted.

First, you should make sure that the pump toggle switch is in the "0" position. To open the protective housing, turn the two locking knobs 100º anti-clockwise. Positive pole: Pull the safety cap off the positive pole connection of the battery and plug the positive cable firmly onto the battery plug. Negative pole: This connection is already firmly plugged in. You should only check that the plugs are tight and that the polarity is correct. Now you can close the protective housing again and turn the locking knobs clockwise back to their previous position.

The spray pipe (10) is sealed to the hand valve (8) using the 16x3 mm O-ring. You can now screw the union nut (a) onto the hand valve by hand. When not in use, the spray pipe is attached to the holder.

Now screw the nozzle attachment (11) with the 10x2 mm O-ring hand-tight onto the spray pipe. A flat jet nozzle (a) is installed at the factory as the standard nozzle.

A ball valve filter (b) is installed in front of the spray nozzle in the angle piece to minimize dripping from the nozzle when the manual valve is closed.
