2 Preparing the device for use
2.1 Assembly
The backpack sprayer is dismantled before it is
dispatched. It must be fully reassembled again
before it is used.
Installation of the pump lever:
Fig. 3 – Fig. 7
The pump lever can be attached to either side of
the device. The figures show mounting on the left
(on the right, mounting is performed accordingly).
Fig. 3:
When fitting the pump lever, the retaining tube (b)
of the pump lever should be facing upwards and
back (facing towards the tank inscription).
Fig. 4 , Fig. 5:
1. Push washer onto the shaft
2. Push pump lever onto the shaft
3. Screw the pump lever to the shaft with screw
and washer, secure with nut.
Fig. 6:
The pump lever length can be adjusted in three
lengths. For this, depress the pin (i), move the
pump handle (c) and latch the pin (i) in one of the
three bores (j).
Fig. 7:
To put down the device, the pump lever can be
turned up with the pump handle (c) in the holder
pipe (b).
For work, turn the pump lever down again with the
pump handle (c) in the holder pipe (b).
Outside of work, the spraying tube (e) is attached
to the carry handle (d).
Installation of the spray tube:
Fasten the threaded collar (Fig. 2, pos. h) on
straight and firmly screw the spray tube (e) with
O-ring (16x3 mm) hand-tight onto the shut-off
valve (g). Do not use any tools!
At the factory, a yellow flat jet nozzle 02-F80 is
assembled as the standard spray nozzle.
2.2 Checking for operationally safe condition
Before any use, the backpack sprayer must be
subjected to a visual inspection. There must be no
visible cracks at the tank (a), the spray tube (e) and
the nozzle attachment (f).
The following inspections must be performed at
first commissioning and at recommissioning after
extended standstill. During use of the pressure
sprayer, proper function generally must be verified
in operation.
To verify tightness even with the tank pressurised,
build up pressure across the pump and inspect the
entire device. No liquid must escape before
actuating the shut-off valve, even while the tank is
pressurised.
Check the function of the shut-off valve during
application. When releasing the shut-off valve,
spraying must stop and no liquid must escape
anymore.
In case of irregularities, recognisable damage,
leaks or limited function, do not start work but have
it inspected by a specialist workshop.
2.3 Pressure adjustment
The pressure is adjusted
prior to filling the tank by
turning the adjuster
cap (m) on top of the
pressure tank. Press down
the adjuster cap and locate
the selected pressure
marker tooth over the tooth
on the pressure tank.
