1.0 Scope of delivery 

• Owner's Handbook
• Pressure vessel gun (1) for cavity sealing
• Spray set, consisting of spray hoses: angle nozzle (2) and round spray nozzle (3)

2.0 Start-up 

• Open pressure vessel and introduce cavity sealant in form of a 1-litre can.

  Close pressure vessel.

• Connect spray hose to quick-connect coupling.
• Connect apparatus to compressed air supply.

  Working pressure 2-6 bar, max. 8 bar!

3.0 Mode of operation 

• Twisting the air flow control screw in decreases the air flow and thus reduces the material spray mist.

  This facilitates optimum working when preserving open components/surfaces. 

• Twisting the air flow control screw out increases the air flow and thus the material spray mist (for closed cavities).
• The trigger lever has two stages.

  Stage 1 - discharge of air only.

  Stage 2 - discharge of air and material.

• After finishing work, press the first stage to clean the spray hose with compressed air.
• When storing, remember to twist the air flow control screw closed to prevent the material from drying out.
• Clean the gun prior to extended periods of non-use (approx. 2 weeks and upwards).
• To ensure that the spray hoses function properly, do not store the hoses coiled up e.g. in the frame side member area!

  Store spray hoses stretched out.

4.0 Application examples 

• Use the matching spray hoses for the different cavities or surfaces.
• Example - doors and lids:

  Spray hose with angle nozzle. Reduce air flow to keep spray mist to a minimum.

• Example - frame side member:

  Long spray hose with round spray nozzle. Depending on the type, increase the air flow slightly.

• Always keep the spray mist to a minimum so as to avoid fouling and bad smells.

5.0 Safety instructions 

• Do not inhale spray mist.
• Use only in well ventilated rooms.
• Working pressure max. 8 bar.
