41 00... Spray Gun For Cavity Sealant

Courtesy of BMW OF NORTH AMERICA, INC.

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 odours.
