 Weight: 114 g
 Operation: manual trigger
 Compatible with standard cartridge-based sealants, adhesives and installation foam

How to use
Prepare the cartridge by cutting the nozzle to the required bead size and puncturing the cartridge seal if present. Insert the cartridge into the gun, ensuring it is seated securely, and engage the trigger mechanism. Apply steady pressure to the trigger while moving the gun along the joint at a consistent speed to achieve an even bead. Release the trigger to stop dispensing and wipe excess material from the nozzle. After use, clean any residual material from the gun according to the sealant or foam manufacturer's recommendations and store the tool in a dry place.
Usage recommendations
Use appropriate personal protective equipment such as gloves and safety glasses when dispensing installation foam or reactive sealants. For best results, choose a nozzle size that matches the gap width and maintain a consistent trigger speed for an even application. Store the caulking gun away from direct sunlight and extreme temperatures to preserve the tool condition.
