3. INSTRUCTIONS FOR CORRECT AND SAFE USE
WARNING
This equipment should only be utilized with agricultural chemicals approved by the
regulatory authorities in your country for use with knapsack sprayers.
For the possibility of using the equipment in the application of other substances,
consult the manufacturer.
Guarany does not recommend the use of chemical products based on flammable
solvents and highly concentrated fertilizers, such as ammonium nitrate and
C
sulfate (ammonium salts) and lime sulphur syrup in high concentrations.
During the handling and application of agrochemicals the use of
Personal Protective Equipment (PPE) is mandatory. Read the label and
package instructions of the chemical to determine what PPE (Personal Protection
Equipment) should be used and any other forms of protection needed during the
handling of these products.

Figure 7
1º - After assembling the equipment, fill the tank with the prepared agrochemical
by passing the liquid through the filter (Item 2);
2º - The harness straps for this sprayer come with a new coupling and quick
release system (Figure 7A), which allows you to secure the strap with the
equipment already placed on the back (Figure 7B), providing greater agility at
work and the release of same just by turning the buckle in the direction indicated
by the arrow in (Figure 7C). This provides greater safety when it is necessary to
remove the knapsack sprayer quickly;
3º - Place the equipment on the back, by adjusting the straps through the
adjustable harness buckles (Figure 1);
4º - Move the pump lever until the desired working pressure is reached; the
equipment has a pressure relief valve (Figure 4) that will be activated when the
pressure in the tank exceeds 500 KPA (75 PSI). Note that when activated it may
make a slight noise, indicating the correct working pressure has been reached.
5º - To adjust the conical spray jet, simply turn the adjustable nozzle tip (Figure
3B).
4. SPRAY MAINTENANCE
Never leave the remains of agrochemicals in the spray tank; wash your sprayer
with clean water at the end of every workday, fill the tank to about 25% of its
volume with water and then spray for about 1 minute, into the an appropriate
container, allowing for thorough cleaning of the equipment. Follow this with the
lubrication procedure:
Double bushing lubrication (Figure 8): For lubrication of the dual bushing
(item 16) you should first remove the clip and then remove the upper part of the
lever pump rod (Figure 5 C), unscrew the pump-securing cap (item 7) and
withdraw the mixer (item 29) fixed into the pressure cylinder (item 20) inside the
chemical tank (for this you must use PPE (Personal Protection Equipment) and
proper gloves to avoid contamination). Remove the pressure cylinder (item 25)
and coat the inner wall with grease or Vaseline to allow lubrication of the dual
bushing when in operation.
Lubrication of Super 3 discharge valve (Figure 9): Disengage the items (G)
and (F) (Figure 6) and through one of the apertures add 3 drops of two-stroke
engine oil into item (F) (Figure 6) allowing the lubrication of the entire needle valve
assembly (item 44)
5. TROUBLE SHOOTING
