1.0 Delivery specification:
- Owner's Handbook
- Pressure reservoir spray gun (1) for cavity sealant
- Spray set, consisting of spray hoses: Angle nozzle (2) and round spray nozzle (3)
IMPORTANT: Prior to start-up read and familiarize yourself with the manufacturer's operating and safety instructions.
2.0 Start-up:
- Open the pressure reservoir and insert the cavity sealant in the form of a 1-liter can.
  Close the pressure reservoir.
- Connect the spray hose to the quick-release coupling.
- Connect the device to the compressed air supply.
  Operating pressure 2-6 bar, max. 8 bar!
3.0 Operating principle:
NOTE: Unlike previous devices you can alter the spray pattern on this device with the air volume regulating screw (large knurled screw).
- Twisting the air volume regulating screw in decreases the air volume and thus reduces the formation of material mist.
  This facilitates optimum working when preserving open components/surfaces .
- Twisting the air volume regulating screw out increases the air volume and thus increases the formation of material mist. (For closed cavities)
- The trigger has two settings.
  1st setting - air discharge only.
  
  2nd setting - air and material discharge.
- After finishing work, press the first setting to clean the spray hose with compressed air.
- Prior to storing, remember to twist the air volume regulating screw closed to reduce the risk of the material drying out.
- Prior to an extended period of non-use (2 weeks and more), clean the gun.
- To ensure that the spray hoses function properly, do not store them coiled up e.g. in the side member area!
  Store the spray hoses stretched out.
4.0 Application examples:
- Use the appropriate spray hoses for the different types of cavity and surface.
- Example - doors, lids and hatches:
  Spray hose with angle nozzle. Reduce air volume to keep the formation of mist low.
- Example - side members:
  Long spray hose with round spray nozzle. The air volume must be increased a little, depending on the type used.
- Basically, keep the formation of mist low to avoid fouling and unpleasant odors.
5.0 Safety instructions:
- Do not inhale spray mist.
- Use in well ventilated rooms only.
- Operating pressure max. 8 bar.
