Assembly

The Sprayer is assembled except for the pump lever which can be attached to either side. (discharge hose and lever grip already fitted) I-off lever grip (LX lever model). The pressure sprayer is supplied with fittings for assembly of the lever grip (LX lever) preattached on the left-hand side (facing towards the tank inscription). If you prefer the lever grip (LX lever) to be mounted on the opposite side, reposition the safety clips (a) on the r.h. side.

When fitting the LX lever, the retaining tube (b) of the LX lever should be facing upwards and back (facing towards the tank inscription).
If you prefer the lever grip (LX lever) to be mounted on the opposite side, reposition the safety clips (a) on the r.h. side.
To store the device, raise the pump handle (C) of the LX lever in the retaining tube (b) and suspend the spray tube in both clips (d).
To work the pump handle (c),lower it again in the retaining tube (b).
The spray tube is connected to the shut-off valve by means of screw cap.

Correct choice of

The spray tube is connected to the shut-off valve by means of screw cap (e).
For the treatment of shrubs, bushes and trees (three dimensional distribution) we recommend the use of the hollow cone nozzle (f). For area treatment (two dimensional distribution) we recommend the use of a flat spray nozzle (g).
For the treatment of tall bushes or trees, a brass tree lance (150cm length) is available as an accessory (part no. 49 00528).

Pressure adjustment

To regulate the output quantity/ droplet size, the spray pressure can be adjusted in steps from 1-4 bar.
The pressure is adjusted prior to filling the tank by turning the adjuster cap (h) on top of the pressure tank. After any pressure in the pressure tank has been released via the shutoff valve, press down adjuster cap and locate the selected pressure marker tooth over the tooth on the pressure tank.
Should spray pressure in excess of 4 bar be required we recommend to replace the pressure valve with the pressure plug (i)(part no 42 00 215) which is supplied with the unit. Release any pressure in the pressure tank first before replacing the valve. A spanner width of 24 mm is required.

Volume of spray solutions

Prepare spray solution according to the instructions provided by the chemical manufacturer. Prepare only as much solution as is required for the job. nate the environment or water mains network.

Medium Volume Guide for Plant Protection:

• Ground Plants 0.3 - 0.5 Itr. for 10 m2
• Espalier trees, pencil bushes 0.5 - 1.0 Itr. per plant
• Taller bush trees 2.0 Itr. per plant.
• Older, free standing trees 3.0 - 5.0 Itr. per tree
• Small Shrubs 1.0 - 1.5 Itr. for 10 m2

Preparing spray solution

Prepare solution outside, never within living areas, stables or n storage area for foodstuff.
Prepare solution with powder chemicals in a separate container. Mix well and then transfer to sprayer tank.
NOTE:
If necessary, the solution can be re-agitated in the tank by stirring with the spray tube.
With liquid plant protection chemicals (if full tank is required), fill sprayer tank 1/4 full with water, add prediluted chemical and then add remaining water as required.
When applying organic spray solutions please filter the solution as or before pouring into the spray tank.
Always observe the Safety Notes provided by the chemical manufacturer!

Filling

When filling the spray tank always use the filter provided with the machine and observe the total filling process.
Avoid a direct connection between water hose and spray tank.
Spray Chemical may not reach the water mains.
When filling ensure that no spray chemicals will contaminate the environment or water mains network.
Avoid any overflow from the tank and any contamination of public waterways, drainage and water channels.

Spraying

Prime the pump with a few up and down strokes of the pump lever. By squeezing the shut-off trigger valve, liquid will be forced through the spray nozzle. When the shut-off trigger valve is released, the spray will stop.

Maintenance and care

The SOLO Backpack Sprayer is almost maintenance free. If the tank lid becomes hard to tighten or open, apply all to the lid gasket.
Proper Maintenance also includes:

• Regular check of the spray tank,
• Regular check of spray line and screw connectors,
• Clean all filters and check for any damage.

To protect piston, cylinder and piston collar (models 425/435/ 473P) from impurities in the spray solution, an additional filter is fitted on the inlet side of the pressure tank. This filter can be cleaned by vigorously shaking the tank when flushing it.
With models 425/435/473P: After disassembly of pump components or after replacing the piston collar, use water resistant grease to lubricate the piston and the collar.
In case of unexpected problems please refer to your SOLO Dealer.

Storage

Even through the tank is manufactured from UV- stabilized material we recommend that the unit is protected from direct sunlight and stored in a dry room, away from children and animals. In areas subject to frost, always drain all the liquid from tank, pressure tank and hoses. Please always use SOLO Original Replacement Parts available from your SOLO Partner.
