PREPARATION OF THE KNAPSACK SPRAYER
MOUNTING THE LANCE Lower the lever in the direction that you will follow to carry out the treatment.
Check for the presence of the OR on the handle E and screw the barrel L on the handle E (fig. 7). Unscrew the ring N from
the handgrip E and insert it into the pipe G. Stick completely the tip of the pipe G on the rubber holder of the handgrip E.
Tighten until the end the ring N on the handgrip E (fig.7). Mounting the hose: Completely introduce (Fig. 8) the end of the
hose onto the relevant connector of the handle and tighten the ring nut by turning it clockwise. Mounting the shoulder
strap: fold in half the shoulder strap and insert the folded side into the slot under the handle (Fig. 2); secure it then with
the plastic tab. Mount on the two free ends the hooks (Fig. 3) adjusting the length.
CHANGING THE POSITION OF THE THROTTLE FROM LEFT TO RIGHT The knapsack sprayer is supplied with left throttle.
To change the position of the throttle, remove the snap ring that secure the connecting rod on the throttle (Fig. 9-A),
remove the other retaining ring that secure the throttle at the opposite end of the tank (Fig. 9-B). Remove the throttle
from the connecting rod and from the base of the tank (Fig. 9-C). Pull the shoulder straps (Fig. 9-D). Insert the throttle
into the opposite seat (Fig. 10-E). Insert the connecting rod into the throttle (Fig. 10F). Place the brass washer at the end
of the throttle and secure the whole with the pressure mounted snap ring (Fig. 10-G). Replace the snap ring on the
connecting rod, throttle side, by pressure mounting it (Fig. 10-M). Attach the shoulder straps (Fig. 10-N).
FILLING THE TANK Remove the lid and fill the tank by pouring the liquid previously prepared through the filter of the
mouth of the tank. The fluid level must never exceed the bottom of the filter. Replace the cover and screw it tight.
CONDITIONS OF USE Attach the hook of a belt of the shoulder strap, lever side, to the protrusion at the bottom of the
tank (Fig. 5). Insert the arm into the belt just hooked (Fig. 6) and place the knapsack sprayer on the shoulder. Grasp the
other strap, carry it on the free shoulder and hook it in the same way described below for the other side. With the handle
in the closed position, operate the knapsack sprayer until you feel some resistance, then spray, acting on the handle,
continuing pumping regularly. Adjust the jet depending on the treatment to be carried out, by turning the terminal part
of the sprayer. Choose the desired spray pattern (Fig. 7).
AFTER USE Pour all the remaining liquid into a container and rinse thoroughly with clean water inside the tank and the
hose, spraying clean water through the lance nozzle. Check that the filters are clean and that the water used for rinsing
has completely emptied. Close the tap of the handle and store the knapsack sprayer upside down in a clean, dry place
inaccessible to children, protected from sun and frost.
MAINTENANCE Always keep clean, intact and greased all seals, valves, the pumping device and its components. The
breakage or hardening of even one of these components may impair the proper functioning of the knapsack sprayer. Be
careful to correctly reassemble the components. In case of poor dispensing quality, clean the end of the sprayer with
clean water.
