WARNING: This page is about a different variant/trim than selected.
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.
