## Long description

The Proline Spray Gun Proline 8 Bar is a compact handheld tool designed for washing and oiling tasks at a maximum operating pressure of 8 bar. Intended for workshop and maintenance use, the spray gun accepts water-based cleaning agents and light lubricants to deliver targeted spray for vehicle care, machinery upkeep, and surface treatment. Its ergonomic form factor and simple trigger mechanism provide controlled application while minimising overspray and product waste.
Advantages
This spray gun combines a robust body with a compact design that is suitable for confined work areas. The device supports precise control of flow through a manual trigger, enabling accurate application of water-based cleaners and light oils. The operating pressure rating up to 8 bar ensures sufficient spray force for rinsing and degreasing while remaining within safe limits for routine maintenance tasks. Materials and construction are chosen to resist common workshop fluids and allow straightforward cleaning after use.
Suitable for
 Washing vehicle exteriors and undercarriages
 Applying water-based cleaning agents to machinery and equipment
 Light oiling and lubrication of moving parts

Key specifications

How to use
Connect the spray gun to a compatible compressed air or water source according to the workshop setup and ensure system pressure does not exceed 8 bar. Fill the connected reservoir or feed line with the appropriate water-based cleaner or light lubricant, then test-spray onto a safe surface to confirm spray pattern and flow. Hold the gun at the recommended working distance for the applied medium, squeeze the trigger smoothly to apply product, and release to stop flow. After use, flush the spray path with clean water or a suitable cleaning fluid to remove residue and prevent nozzle clogging.
Usage recommendations
Use only water-based cleaning solutions and light oils specified for spray application. Wear appropriate personal protective equipment when handling chemicals. Regularly inspect seals and fittings for wear and perform routine cleaning of the nozzle and passages to maintain consistent spray performance.
