Frequently Asked Questions - Pro 500 GLORIA

How to open the tank safely?

To open the tank, depressurize it by turning the pressure relief valve to the left until it stops. Let the air escape, then slowly turn the pump handle to the left to release remaining air and unscrew the pump.

What liquids can be used in the sprayer?

Only liquids with a pH between 5 and 9 can be used. Avoid highly corrosive, solvent-containing, or flammable liquids (flash point < 60 °C). Never mix different liquids.

How to pressurize the device?

After filling the tank, screw on the pump, unlock the handle lock, then pump until reaching 3 bar (the pressure relief valve lifts). Then lock the handle.

What to do if the nozzle is clogged?

Depressurize the tank. You can unclog the nozzle with a sharp object (e.g., pin). For the PRO 500 Jet model, disassemble the nozzle and filter, then rinse them with a suitable cleaning liquid.

How to clean the sprayer after use?

Depressurize and empty the tank. Clean the tank, hose, lance, and filters with a suitable cleaning liquid. Follow the cleaning instructions for the sprayed liquid.

How to maintain the seals?

Regularly grease the pump and quick-closing valve seals with a resin-free and acid-free silicone grease (ref. GLORIA 728781.1111). Replace worn seals if necessary.

What to do if the pump does not generate pressure?

This usually indicates worn pump seals. Replace the pump seals after depressurizing and opening the tank.

How to store the device?

Store the sprayer depressurized and empty, open to prevent mold. Protect it from frost and prolonged sun exposure. Keep out of reach of children.

What is the optimal spraying distance?

The optimal distance is 40 to 50 cm between the nozzle and the target. For continuous spraying, you can lock the lever on the quick-closing valve.

The pressure sprayer is designed for applying commercially available, low-viscosity and pure spraying agents and is suitable for private, professional and industrial applications.

Only spraying agents with a pH value between 5 and 9 may be used.

You may only operate the pressure sprayer within the operating temperature range (see Chapter "10 Technical data" on page 11).

2 Information for safe use

Read and observe the operating instructions and follow all safety instructions.

Keep the operating instructions in a safe place for later use. If you hand over the

pressure sprayer to someone else (for example, sell it), you must also include the operating instructions.

Spraying agents are mixtures of different substances whose composition is only known by the spraying agent manufacturer. Check the suitability of the spray-

ing agent before use. If you have any questions about the suitability of a spraying agent or you are unsure, please contact the spraying agent manufacturer or the Gloria Service department.

Do not fill the container with any spraying agents that contain solvents or are highly caustic. Do not mix different spraying agents. Unexpected, dangerous chemical reactions can occur.

When you use flammable, explosive spraying agents, the explosion protection guideline (Ex-RL) and the regulations for the use of flammable liquids (VbF) must be observed.

You may not use any flammable, explosive liquids in areas where there is a risk of explosion.

Do not spray any explosive, highly or easily flammable, combustible liquids with a flash point below 60 °C in areas where there is no risk of explosion.

Keep the pressure sprayer away from sources of ignition.

Observe the safety instructions of the spraying agent manufacturer. Always request a safety data sheet from the spraying agent manufacturer. Observe

the specified maximum concentration of the spraying agent. Some spraying agents require that you wear filter masks, protective goggles, protective gloves and a protective suit. Wear the required protection equipment. Do not try to clear blocked nozzles by blowing them out with your mouth.

If you come into contact with caustic or skin-irritating spraying agents, rinse the affected areas with plenty of clean water and consult a doctor.

Only eat, drink or smoke after removing your protective equipment and carefully cleaning your hands and face.

Do not modify or repair the pressure sprayer yourself. Do not modify or remove safety devices.

Faulty pressure sprayers may only be repaired by an authorised workshop.

Do not allow children to play with the pressure sprayer. Keep minors under the age of 16 away from the pressure sprayer. The pressure sprayer may be used by minors over the age of 16 and by persons with reduced physical, sensory or mental capabilities or a lack of experience and knowledge, but only if they are supervised or have been instructed in using the pressure sprayer safely and understand the risks involved. Cleaning and maintenance must not be undertaken by minors under the age of 16. Minors over the age of 16 must be supervised during cleaning and maintenance.

Residual risks: The pressure sprayer complies with the recognised rules of technology and the relevant

safety regulations. Nevertheless, some residual risks remain. Observe all safety instructions.

Limitation of liability: According to the Product Liability Act, the manufacturer is not responsible for damage caused by failure to comply with these operating instructions, by improper use or by unauthorised repairs.

3 Overview

Parts of the pressure sprayer

1 Hose line	9 Base ring
2 Lever	10 Container
3 Quick-acting valve	11 Filling level indicator
4 Lock	12 Shoulder strap
5 Spray lance	13 Union nut with kink protection
6 Nozzle
7 Overpressure valve	14 Filling funnel
8 Receptacle	15 Pump handle

4 Assembly

Assemble the pressure sprayer as shown in Figures A. Make sure that you fit the union nuts on straight. The union nuts must not be cross-threaded.

After assembly, check all screw connections are secure. In particular, make sure the overpressure valve is screwed tight.

5 Operation

Opening the container

Observe the following safety information:

- You may only open the container if it has been depressurised.

1. Release the pressure from the container by turning the overpressure valve left to the stop (see Figure B). Allow the pressurised air to escape completely.
2. Turn the pump handle slowly to the left. Allow any pressurised air remaining in the container to escape (see Figure C1).
3. Turn the pump handle further to the left to screw out the pump (see Figure C2).

Filling the tank

Observe the following safety instructions:

• Check that the overpressure valve moves freely before filling.
  ■ Do not hold the overpressure valve closed.

• Place the pressure sprayer on a flat and level surface.

• Release the pressure from the container and open the container.
• Pour the spray liquid into the container. Observe the maximum filling quantity (see Figure G).
• Insert the pump in the filling funnel.
• Screw the pump into the container using the pump handle.
• Release the catch on the pump handle (see Figure F1).
• Place both feet on the extended part of the base ring and hold the container securely between your legs.
• Press the pump handle until a pressure of 3 bar is reached (see Figures H). Observe the pressure indicator on the overpressure valve (see Figures D). As the pressure rises, the overpressure valve rises and you will hear the overpressure valve release air when the maximum pressure of 3 bar is exceeded.
• Lock the pump handle (see Figure F2).

Spraying

Observe the following safety instructions:

■ Before use, check that all screw connections are secure. Tighten any loose screw connections.
■ Before every use, check the pressure sprayer for any damage, leaks and proper working order. Do not use the pressure sprayer if it is faulty.
- Note the direction of the wind. Do not spray into the wind.
■ Never direct the spray jet at people or animals.
■ Do not spray flammable liquids onto hot surfaces.
- If possible, spray the whole contents of the container.

Direct the nozzles at the object being sprayed and operate the lever on the quick-acting valve. The ideal spraying distance is 40 to 50 cm.

To spray continuously, you can lock the lever on the quick-acting valve (see Figure E).

Press the pump handle if spraying pressure drops.

Emptying the container

1. Release the pressure from the container and open the container.
2. Pour the remaining spraying agent into a suitable vessel.
3. Dispose of the remaining spraying agent in accordance with applicable laws and regulations. Also, follow the disposal instructions on the spraying agent packaging.
4. Clean the pressure sprayer.

6 Cleaning and maintenance

Clean the pressure sprayer thoroughly after each time you use it.

1. Release the pressure from the container and open the container.
2. Empty the container.
3. Clean the container, the hose line, the spray lance and the filters with a suitable cleaning fluid (see Figure J). Also, follow any cleaning instructions on the spraying agent packaging.

Grease the seals on the pump and on the quick-acting valve on a regular basis, but at the latest when the pressure sprayer function is impaired (see Chapter "9 Troubleshooting" on page 10).

You may only use resin- and acid-free greases. You can obtain a suitable silicone grease from GLORIA (item number 728781.1111).
