How to use

To use the JOBIextra XT099, first press the release lever at the back of the gun to retract the plunger rod fully. Insert the sealant or adhesive cartridge into the frame, ensuring the nozzle is positioned through the front opening. Once the cartridge is secure, squeeze the trigger repeatedly to advance the plunger until it makes contact with the base of the cartridge. Cut the nozzle of the cartridge to the desired bead size and angle. Apply steady pressure to the trigger to dispense the material, moving the gun along the joint at a consistent speed. When finished, release the pressure by pressing the release lever again to prevent material from continuing to ooze.

What to consider before purchase

• Check the size of your sealant cartridges to ensure compatibility
• Consider the frequency of use to determine if a manual tool meets your needs
• Ensure the nozzle tip is cut correctly for your specific sealing task

Usage recommendations

Always clean the nozzle and the gun frame after use to prevent residual material from hardening and affecting future performance. Store the tool in a dry place to maintain the integrity of the mechanical components.
