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)

IMPORTANT: Before start-up, read Owner's Handbook and safety instructions.

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

NOTE: Unlike previous apparatus, it is possible here to alter the spray pattern with the air flow control screw (large knurled screw)!

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.
