Setup and Operation
Follow these steps for proper setup and operation of your Stanley PRO-FG2 Foam Gun:
- Prepare the Foam Can: Shake the foam can vigorously for at least 20 seconds before use to ensure proper mixing of contents.

- Apply Foam: Press the trigger to apply foam evenly. For optimal adhesion, slightly mist surfaces with water before application.
- Fill Gaps: When filling gaps, apply foam halfway as it will expand to fill the remaining space.
- Application Distance: Apply the insulation foam at a distance of approximately 40-45 cm (16 inches) from the surface for optimal coverage and expansion.

Maintenance and Cleaning
Proper cleaning and maintenance are crucial for the longevity and performance of your foam gun:
- Immediate Cleaning: Always clean the nozzle and gun immediately after each use with a dedicated foam cleaner. This prevents foam from curing inside the gun, which can cause blockages.
- Storage: Store the foam gun upright with a can attached, or ensure it is thoroughly cleaned and the valve is closed if storing without a can.
- Pro Tip: If you plan to reuse the gun soon, leaving a can of foam attached can help prevent the internal mechanism from drying out.
