SAFETY GUIDELINES - DEFINITIONS

It is important for you to read and understand this manual. The information it contains relates to protecting YOUR SAFETY and PREVENTING PROBLEMS. The symbols below are used to help you recognize this information.

3. General Power Tool Safety Warnings

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

3.1. Work area safety

  • Keep work area clean and well lit. Cluttered or dark areas invite accidents.
  • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

3.2. Electrical safety

  • Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
  • Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
  • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
  • Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
  • When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
  • If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

3.3. Personal Safety

  • Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
  • Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
  • Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
  • Remove any adjusting key (wrench, screwdriver...) before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
  • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
  • Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
  • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

7. Important Safety Instructions for Sprayers

DANGER!

WARNING!

7.1. Triple rinse of empty agrochemicals containers

NOTE: Even the containers considered empty contain chemical residues. Therefore, discarding the containers without washing out the residues is extremely dangerous to man, animals and environment. In the case of metal, plastic and glass chemical containers, each container must be rinsed three times to ensure the residues are completely removed. This manual describes how to make the triple rinse in a correct, safe and effective way.

  1. Immediately after emptying the container, you must keep it with the opening upside down over the sprayer tank opening or over the bucket that you are using to prepare the chemical mixture for at least 30 seconds, until no residue is left in the container, when the drops are falling in long intervals.
  2. Hold the container in the upright position and fill it with water up to 1/4.
  3. Install the container cap and tight it enough to avoid leakage during the agitation.
  4. Agitate the container strongly in all ways (horizontal and vertical), for approximately 30 seconds to remove the residues that are on the container internal walls.
  5. Take the container cap off and carefully pour the rinse water into the spray tank.
  6. Keep holding the container over the spray tank opening for approximately 30 seconds to the last drop.
  7. Repeat this operation twice more. This way, you complete the triple rinse.
  8. Make the plastic and metallic containers useless by piercing the container bottom with a pointed instrument. This way, their labels are not damaged for identification purposes.

8. Preparation for use

NOTE*: Nozzle has not reached working pressure (15 psi).

NOTE**: The values above may vary as to the wear, clogging and variation of the nozzles, the density and viscosity of the liquid to be applied, the temperature and relative humidity of the environment, the altitude and consequent atmospheric pressure of the site, the height of the lance spraying, etc.

NOTE***: The minimum working nozzle pressure should always be observed, so we do not recommend spraying at pressures below 15 psi for fan nozzles and below 45 to 60 psi for conical nozzles depending on the model. In addition, we do not recommend using ISO standard nozzles of brown color (05 gal/min at 3 bar pressure).

9.2. Calibration of battery powered knapsack sprayer

PROCEDURE

  1. USING CALIBRATOR BOTTLE (OPTIONAL)
    1. Hold the lance at the working height and spray to measure the application band width.
    2. Based on the band width, calculate the total walking distance required to spray the desired area. Use the chart as shown next.

Diagram showing the components of a calibrator bottle: Lance, Cover, Filter, Nozzle, Nozzle cap, Calibrator bottle.

Diagram showing two actions: "Record the time it takes to walk 25 m²" and "Simulate the spraying of 25 m²".

  1. Hold the lance at the normal working height and spray into the bottle while walking the distance required to spray an area corresponding to 25 m².
  2. Place the bottle on a level surface and observe the liquid level visible through the side of the bottle. Match the liquid level to the corresponding scale on the calibrator bottle.
  3. Empty the bottle and repeat this operation to determine the average of two or more readings.

NOTE: For the volume in liters per bushel (L / alk), simply multiply the value obtained in liters per hectare (L / ha) by 2.42.

9.4. Solution preparation and tank filling

  1. To dilute and premix the product, place 5 liters of water in a separate container;
  2. Mix to a homogeneous solution and pour into the sprayer tank during filling.

WARNING! Use the correct dose and volume of chemical according to the product label.

9.5. Shoulder strap adjust

11.1. Influence of climatic conditions

During application, some factors may determine the interruption of the spraying. Wind currents, for example, can drag drops to a greater or lesser distance in terms of its size or weight. The temperature and especially the relative humidity contribute to the rapid evaporation of the droplets.

The ideal conditions for spraying are:

  • Relative humidity: minimum 50%;
  • Wind speed: 3-10 km / h;
  • Temperature below 30 C.

These limits should be considered according to technology application that will be used, adopting the safest class droplets within the boundaries of each situation.

10. Maintenance and Storage

For extended product life, follow these important care instructions:

  • When filling up the tank, always use the strainer provided. This will reduce the chance of undesirable debris that could damage the pump.
  • Do not operate the sprayer without the pump suction filter. This can severely damage the pump. Periodically clean or replace this filter as follows:
    1. Empty the tank, make sure the sprayer is turned off and put it upside down;
    2. Remove screw A;
    3. Remove base cover B;
    4. Unscrew filter cover C;
    5. Clean or replace filtering element D.

WARNING! Use of individual protective clothing and safety equipment is required.

  • Only fill the tank with a water soluble agrochemical or an already mixed powder liquid form through the filling filter. Do not prepare mixtures directly in the sprayer tank;
  • This sprayer is an electronic tool and must be protected from severe environmental conditions. When not using, do not leave the sprayer in sun, rain or frost;
  • Do not submerge the sprayer completely or partially;
  • After finishing the application, clean and wash all equipment in an approved decontamination area;
  • Clean the sprayer before storage. Circulate fresh water through the tank, pump and hoses after each use. This will help remove chemical residues and extend life of sprayer parts;
  • The spray lance can be conveniently stored on the clips on the side of the tank;
  • Nozzles and filters must be periodically cleaned or replaced. Do not clean nozzles or filters with sharp hard objects, nor blow through them using the mouth;
  • Before storage the sprayer during periods of harsh winter, in temperatures less than 0° C, circulate fresh water through the tank, pump and hoses. Release the trigger valve to drain all the liquid inside the sprayer. Use antifreeze if necessary. Make sure there is no liquid inside the tank before you storage the sprayer in a safe place.

WARNING! Discard the liquid used to clean the sprayer in a proper and approved local for this purpose. Do not contaminate the environment.
