- If the cartridge has a sealed inner membrane, use the integrated puncture tool (located at the front of the caulk gun) to pierce it.
Operating Instructions
1. Adjusting Dispensing Speed
The caulk gun features an adjustable speed dial to control the flow rate of the material. Rotate the dial to select the desired speed (1 for slowest, 6 for fastest). Start with a lower speed and increase as needed for your application and material viscosity.
