4. Assembly

The Sprayer is assembled except for the pump lever
which can be attached to either side. (discharge hose
and lever grip already fitted) 1-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.

5. Correct choise 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).

6. 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.
