General Safety Instructions

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 refer to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. Work area safety
2. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
3. 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.
4. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
5. Electrical Safety
6. Users should only use power tool plugs that match the outlet they are intending to use. The plug should not be modified in any way as it could lead to electrical hazards. It is also advised not to use any adapter plugs with earthed (grounded) power tools. Using unmodified plugs and matching outlets will help reduce the risk of electric shock. It is important to follow these instructions to ensure safe operation of power tools and to prevent electrical accidents.
7. 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.
8. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
9. 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.
10. When you use a power tool outside, make sure you choose an extension cord that can be used outdoors. This will help to lower the possibility of an electric shock. f) If you have to use a power tool in a damp area, be sure to use a power source that has residual current device (RCD) protection. This will help to lower the possibility of an electric shock.
11. Personal safety
12. When you use a power tool, you must pay attention to the operation and use common sense. Do not use power tools when you are tired or under the influence of drugs, alcohol, or medication, as a moment of carelessness can cause serious personal injury.
13. You should use personal protective equipment when using a power tool. Always wear eye protection. Using protective equipment such as a dust mask, non-slip safety shoes, hard hat, or ear protection in the appropriate environment can reduce personal injuries.
14. To avoid unintentional start-up, make sure the switch is in the off position before connecting to the power source and/or battery pack, or picking up or carrying the tool. Carrying power tools with your finger on the switch or starting a power tool with the switch on can lead to accidents.
15. Always remove any adjusting key or wrench before turning the power tool on. A wrench or key left attached to a rotating part of the power tool can cause personal injury.
16. Do not reach too far. Always keep your footing and balance. This will enable better control of the power tool in unexpected situations.
17. Dress properly. Do not wear loose clothing or jewelry, and keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can get caught in moving parts.
18. Do not lull yourself into a false sense of security and do not think yourself above the safety rules for electric tools, even if you are familiar with the electric tool following extensive practical experience. Careless use can lead to serious injuries in fractions of a second.
19. Power tool use and care
20. Do not force the power tool. Use correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
21. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
22. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
23. Store idle power tools out of reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
24. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
25. Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
26. Keep the handles and grip surfaces dry, clean and free of oil and grease. Slippery handles and grip surfaces hamper safe operation and control of the electric tool in unforeseen situations.
27. Service
28. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
29. If the supply cord is damaged, it must be replaced by the manufacturer or it’s service agent or a similarly qualified person in order to avoid a safety hazard.
30. Safety Instructions for Spray Guns
    Caution : Paint mist and solvent vapors can be harmful to your health. Always wear breathing equipment and work only in well-ventilated rooms or use supplementary ventilating equipment. It is advisable to also wear protective clothing, safety glasses, ear protection, and gloves.

• CAUTION: DANGER OF INJURY! Never point the spray stream towards human beings or animals.
• ****Sockets and plugs must be covered to prevent the risk of electric shock from sprayed material entering the socket.
• Attention: Do not operate the device if the nozzle seal is damaged or missing. If the nozzle seal is damaged or missing, liquids can enter the device and increase the risk of electric shock. Check the nozzle seal before each use and tighten the union nut.
• Do not use the spray gun to spray flammable substances.
• The spray guns are not to be cleaned with flammable solvents.
• Be cautious of the dangers that can arise from the sprayed substance, and follow the instructions and information on the containers or provided by the substance manufacturer.

Field of application

• This product is suitable for use with water- and solvent-based paints, finishes, primers, 2-component paints, clear finishes, automotive finishes, staining sealers, and wood sealer-preservatives. It is also compatible with all coating materials that bear the red Perfect Spray logo

Coating Materials Suitable for Use

• Interior wall paint (dispersions and latex paint)

Coating Materials Not Suitable for Use

• Materials that contain highly abrasive components, façade paint, caustic solutions and acidic coating substances. Flammable materials. 8. The following materials can only be processed with optional accessories: Water- and solvent-based paints, finishes, primers, 2-component paints, clear finishes, automotive finish, staining sealers and wood sealer-preservatives.

Preparation of the workplace

• Sockets and plugs must be masked. Risk of an electric shock as a consequence of sprayed material entering the socket!
• Mask all the areas and objects that are not to be spray painted, or remove them from the work area. No liability is assumed for damage due to overspray.
• Silicate paint corrodes glass and ceramic surfaces upon contact! All such surfaces must therefore be completely covered.
• When using adhesive tape, pay attention to the quality of the tape to ensure good adhesion without damaging the surfaces. Avoid using excessively strong adhesive tape on wallpaper and painted surfaces to prevent damage during removal. When removing the tape, do so slowly and evenly, avoiding jerky movements. Do not leave the tape on the surfaces any longer than necessary to minimize the risk of leaving residues when removing it. Be sure to follow the adhesive tape manufacturer’s instructions to ensure proper use and best results.

Preparation of the Coating Material

• For better spray results, use spray material at room temperature or diluted with warm water. Do not heat spray material above 40°C.
• Interior wall paints can be sprayed undiluted or slightly diluted with the spray attachment provided.

1. Thoroughly stir the material and dilute it in the container according to the recommended dilution, using an agitator if available
   Thinning recommendation

   Sprayed material|
   Interior wall paint (dispersions and latex paint)| dilute by 0-10 %

2. If the feed rate is too low even at the maximum flow setting, dilute the material in increments of 5-10% until the feed rate meets your requirements (while adhering to the maximum allowable dilution specified by the manufacturer).

Start-up

• Before connecting to the mains supply, be sure that the supply voltage is identical with the value given on the rating plate. • Attach the carrying strap to the unit. (Fig. 2) • Unscrew the container from the spray gun.
  • Align the suction tube (Fig. 3) If the suction tube is positioned correctly, the container contents can be sprayed without almost any residue. When spraying horizontal surfaces, turn suction tube forward. (Fig. 3 A) When spraying objects overhead, turn suction tube back. (Fig. 3 B)
  • Place the container on a paper base and pour in the prepared coating substance with using the included feed hopper included in the scope of supply (Fig. 1, 21 ) Screw the container tightly onto the spray gun.

Before use

• Checking viscosity
  • The product allows you to use spray material with a viscosity of maximum. 120DIN/sec.

Measure viscosity

•  Fill the measuring cup [right figure] with spray material
• Let the liquid flow out of the measuring cup [right figure].
• Measure the seconds until the spray material
• Put the paint filter on the container, and filter the measured spray liquid into it through the paint filter.

Notice:

• Stop flowing out of the measuring cup [right figure 1]. The measured result is the DIN/sec value Dilute the spray material gradually with a suitable diluent until you measure a value ≤ 120 DIN/ sec. Only use thinners that are suitable for the respective spray material. Using the wrong thinner can cause lumps to form and clog the product.

• Never mix synthetic resin paints with nitro thinner! Read the manufacturer’s instructions for the respective spray material to find out about the appropriate thinners. Do not spray materials containing granules or solid particles.

•  The table below shows recommended run-DIN-seconds for different types of material

• If the paint takes longer than the recommended time to empty, then further thinning is required. Mix a small quantity of the appropriate thinner into the paint and use the viscosity test until the desired viscosity is reached

  • Attach the front part to the rear part of the gun. (Fig. 5)

• If the paint takes longer than the recommended time to empty, then further thinning is required. Mix a small quantity of the appropriate thinner into the paint and use the viscosity test until the desired viscosity is reached.

• Attach the air hose (Fig. 5 a+b) by firmly inserting it into the connection of the unit and the gun handle The orientation of the hose does not matter. Place the machine only on a level and clean surface. Otherwise, the gun may suck in dust or debris. Put on the carrying strap and sling it over your shoulder. Press the ON/OFF switch on the device to turn it on

Selecting the Spray Setting (Fig. 6)

• WARNING! Danger of injury! Never pull the trigger guard while adjusting the air cap. 3 different spray jet shapes can be set by turning the air cap (fig. 6, 1)
• Tighten the union nut (Fig. 6, 2) fully so that no paint is able to penetrate the device. Check regularly whether the union nut has worked loose during operation.
• Fig. 7A: Vertical flat jet – for spraying on horizontal surfaces.
• Fig. 7B: Horizontal flat jet – for spraying on vertical surfaces.
• Fig. 7C: Circular jet – for spraying on corners, edges, and hard-to-reach surfaces.
• To change the spray jet shape and width, replace the air cap (1) with the desired one.
• 13.Adjusting the Material Volume (Fig. 8) “To adjust the material volume, turn the regulator on the trigger guard of the spray gun:
• Turn left to decrease the material volume. Turn right to increase the material volume. For most wall paints, the best results are achieved with an average flow setting. 14. Spray Technique
• Cover all surfaces that will not be sprayed.
• It is advisable to test the spray gun on cardboard or a similar surface to find the correct settings. Important: Start spraying from the edge of the area to be sprayed. Begin the spray movement first, and then press the trigger. Avoid stopping or interrupting the spray within the area being sprayed.
• The spray movement should come from the arm, not just from the wrist. This ensures that a uniform distance is maintained between the spray gun and the spray surface during the spray operation. Select a distance of 20-30 cm, depending on the desired spray jet width.
• Fig.9 a: CORRECT – Maintain an even distance 20-30 cm between the spray gun and the object.
• Fig.9 b : INCORRECT – Uneven distance will result in uneven paint application.
  • Move the spray gun evenly in a cross-wise or up-and-down motion, depending on the spray pattern setting.
  • Even movement of the spray gun results in a uniform surface quality.
  • If the nozzle and air cap are soiled, clean both parts with water and solvent.
• Use a ‘cross spray’ technique when using paint with poor covering capacity or if the surface is highly absorbent
• (Fig. 10). Interior wall paints in strong color shades should be applied at least twice, allowing the first paint coat to dry first. This will ensure good coverage.

Interruption of Work

• Turn the machine off.
• During longer breaks, vent the container by briefly opening and then closing it again.
• Clean nozzle openings after an interruption in operation.
