Spraying and the Law

1.2

Current legislation requires the operator to assess the risk of all work activities prior to carrying them out. When planning chemical applications, consideration must be given to both personal safety and environmental damage. In both cases risks must be minimised. It is suggested that the following questions are asked before starting application: • • • • •

Am I using the correct product consistent with the problem I am trying to solve? Can I fill the applicator in a way, which minimises personal risk? Is my set up such that maximum beneficial effect will be achieved with minimum environmental damage? Am I working within all the guidelines laid down on the product label? Is my applicator set up to give the correct application rate consistent with my current throughput? ENSURE THAT THE ANSWER TO ALL OF THE ABOVE IS ”YES” BEFORE SPRAYING

General Safety

1.3

Any guards fitted are designed to comply with current legislation and are provided for your safety. The manufacturer will not accept liability for injury caused where safety devices have been removed. Once the Sprayer has been used, assume that it is always contaminated. Always wear suitable protective clothing as specified on the product label when handling any part of the Sprayer. Do not eat, drink or smoke whilst working with the Sprayer and then not until contaminated clothing has been removed and all exposed skin has been thoroughly washed. Take particular care when removing the suction and return hoses from the tank to avoid chemical splashes. WEAR SUITABLE FACE VISOR.

Description

1.4

The SPR30, (30L capacity) and the SPR60, (60L capacity) Pedestrian Sprayers are robust, hand propelled units specifically designed to apply quantities of diluted chemical for treatment of grass/lawn areas. The success of the units revolves around the 12V DC diaphragm pump, which handles most chemicals with ease (must be flushed through with clean water after each use). The SPR 60 is fitted with a Spray/Return valve enabling the operator to recirculate the spray solution whilst moving to the work area, an adjustable pressure regulation valve provides pressure adjustment of the spray solution to the spray nozzles. The spray boom height can be easily adjusted to position the nozzles at the correct distance above the target, (see nozzle application chart). Each unit is supplied with a sealed 12V battery and 240V battery charging system, the sprayer pump will begin to ‘run-slow’ when the battery is losing charge (pump running noise will change), ensure the battery is re-charged when battery is running low and never store unit with a ‘flat battery’.

NOTE: If the power leads are removed from the battery terminals ensure they are reconnected back to the correct position: Brown lead to the Positive (+) terminal. Blue lead to the Negative (-) terminal.

OPERATING THE SPRAYER

Calibration & Nozzle Selection

1.5

The application rate of the sprayer is governed by three factors: 1. Forward Speed 2. Nozzle Size 3. Pressure Walk with the machine and decide upon a comfortable and maintainable forward speed. Mark out 100 metres accurately. Walking at the desired speed calculate the time it takes to walk the 100 metres, (trying to keep the speed constant) 1. Forward Speed = 360 ÷ time to travel 100 metres in seconds. Example: 360 ÷ 60 (seconds) = 6km/hr. Read the spray product label and establish the recommended application rate of water per hectare. Calculate the required nozzle output. 2. Nozzle Size = Application Rate (Ltr/Ha) x Nozzle Spacing (M) x Speed (km/hr) ÷ 600 Example: Application rate 200Ltr/Ha x Nozzle Spacing 0.5M (Normal) x Speed 6km/hr 200 x 0.5 x 6 ÷ 600 = 1.0 Ltr/min. Using the nozzle selection chart for the chosen manufacturer (Hypro supplied as standard), select the nozzle, which will provide the spray quantity defined by the product label. If in doubt choose the larger nozzle at lower pressure in order to minimize drift and blockages. Example: (From Hypro Chart) 1.0 Ltr/min VP02F110 Yellow @ approx 4.5 bar pressure – Fine Spray VP03F110 Blue @ approx’ 2 bar pressure – course spray Fit the selected Nozzles.

Testing the Sprayer

1.6

Always check the calibration of the sprayer with water before commencing to spray with chemical. To check the calibration of the sprayer: Partially fill the tank with clean water and open the spray booms, a hand lance assembly is fitted to the SP60 and can be used instead of the spray boom, the system pressure will have to be adjusted as only using one nozzle, see connection below. Switch On the pump and set the pressure regulator valve to the predetermined pressure, see below. The pressure gauge allows the system pressure to be monitored by the operator.

Pressure regulator valve Boom/hand lance connection

Using calibration jug, check the output from each nozzle. If the nozzles are new, discard any that vary more than +/- 5%. If the nozzles are old, replace the complete set if any vary by more than +/- 5% or show an uneven pattern. NOTE: It may be necessary to adjust the pressure slightly to achieve the correct output. Record the following data: Speed (km/h) Nozzles System Pressure (Bar) Nozzle Output (Ltr/min) Application Rate (Ltr/Ha) Spray/Return valve (SPR60 only) enables the operator to switch the flow from the pump to either feed the boom for spraying or return back to the tank keeping the spray solution in suspension whilst moving from one location to another, see below:

Boom/hand lance connection Spray/return valve

Calculating Quantity of Chemical

1.7

Divide the tank volume by the application rate. Example: 30L Tank ÷ 200 Ltr/Ha = 0.15Ha If this area is larger than the area to be sprayed reduce the volume accordingly. Multiply the area per tank full by the chemical dose rate. Example: Dose rate = 2Ltr/Ha (0.15Ha x 2L = 0.3L)

Adding Chemical to the Sprayer

1.8

Before adding chemicals, ensure the calibration of the sprayer has been carefully checked (see Testing the Sprayer). To add chemicals to the tank: Calculate the quantity of chemical required and follow the chemical mixing procedure as recommended on the product label. Ensure the mixture is well shaken before adding to the tank. After adding the chemical refit the tank lid. SPR30: Set the adjustable pressure regulator valve to the lowest possible pressure setting and then switch on the pump, the sprayer should now run in agitation. Allow the machine to run in agitation for 2-3 minutes. When ready to spray, set the pressure regulator valve to the predetermined pressure. The machine will now spray. Use the pump on/off switch (mounted on handle) to turn the sprayer on and off as required. SPR60: Set the Spray/Return valve to Return and adjust the pressure regulator valve to the lowest possible pressure setting and then switch on the pump, the sprayer should now run in agitation. Allow the machine to run in agitation for 2-3 minutes. When ready to spray, set the Spray/Return valve to spray and the pressure regulator valve to the predetermined pressure, the machine will now spray. Use the Spray/Return valve to turn the sprayer on and off as required, use the pump on/off switch (mounted on handle) to turn the sprayer pump on and off as required. Spray immediately after mixing and continue spraying until the tank is empty. Do not allow the tank contents to stand unagitated for long periods. If this is unavoidable, shake the tank manually to stir up the contents, and then run the machine in agitation before commencing to spray. NOTE: The suction side of the pump is fitted with a filter. Check this filter frequently and clean when required.

Flushing Through with Water

1.9

The sprayer should be flushed out at the end of each days use. The tank and system should be emptied of all remaining liquid before flushing through with water. ALWAYS DISPOSE OF FLUSHINGS SAFELY. To empty the system (SP30): • • • • • • •

Unscrew the tank lid and lift the plastic suction tube clear of the liquid. Switch on the pump and continue spraying until all residues are flushed from the system. Switch off the pump, remove the tank and pour the remaining liquid into suitable container. ALWAYS DISPOSE OF SAFELY. Refill the sprayer with clean water or cleaning solution as recommended on the product label. Switch on pump and continue spraying until all residues are flushed from the system. Clean the outside of the sprayer. Remove all nozzles, nozzle filters and suction filter, rinse and store in a bucket of clean water.

To Empty the System (SP60) • • • • • • •

Empty sprayer of remaining liquid using the drain tap located underneath the tank. ALWAYS DISPOSE OF SAFELY. Switch on pump and continue spraying until all residues are flushed from the system. Refill the sprayer with clean water or cleaning solution as recommended on the product label. Switch on the pump and continue spraying until all residues are flushed from the system. Clean the outside of the sprayer. Remove all nozzles, nozzle filters and suction filter, rinse and store in a bucket of clean water.

Field Operation Notes

1.10

Check the indicated pressure from time to time. Avoid disposal problems by filling the sprayer accurately for the area to be covered. Keep the pump running between filling and spraying in order to maintain a thorough mix.. Set the boom height above the target as recommended by the nozzle manufacturer.

MAINTENANCE Maintenance and Lubrication

1.11

The sprayer is a reliable and straightforward machine to use. However, the following maintenance recommendations should be observed: •

Always flush through with clean water after use. problems due to blockages.



Check the suction filter and clean when required.



It is possible that an accumulation of sediment may cause the pressure regulator valve to stick. If this occurs, release the adjusting screw and carefully remove the cap in the end of the valve body. Remove the plunger (fitted with ‘o’ ring seal). Clean and apply grease. Carefully reassemble taking particular care to relocate the domed disc on which the adjusting screw acts.



Occasionally apply grease to the pressure regulator valve adjusting screw and locking ring.



Check all nuts, bolts and pipe unions are tight, particularly after the first days use.



Occasionally apply grease to the wheel bearings.



Check for perished and chafed hoses.



Rinse nozzles and filters in bucket of clean water after each use.



During times of frost and low temperatures, drain as much liquid as possible from the sprayer and either remove the pump and store in warm place, or add a small quantity of anti-freeze and water to sprayer.
