Maintenance
□ If the gun is not to be reloaded it must be cleaned as soon as possible after the cartridge has been removed to avoid hardening of the
foam inside the gun.
Care and Cleaning
□ Always ensure all foam is released from the gun before cleaning.
□ To clean the foam dispensing gun, unscrew the can of the Insulating Foam Sealant or Adhesive and attach a can of professional
Cleaner, making sure the threads are straight. Pull the trigger and dispense contents into a covered container lined with a disposable
bag, e.g., a trash can with a lid, and dispose per local, state/provincial and federal regulations. Dispense cleaner until there are no
signs of residual foam. This usually requires about half a can of Gun Cleaner. When detaching the cleaner, continue to pull trigger while
unscrewing the cleaner from the gun to help prevent spray back.
□ Leave the solvent in the gun for 2 minutes. Release the solvent by pressing the trigger and repeat this process until the solvent runs
clear and shows no trace of foam. Unscrew the ow control knob and remove the long nozzle, and clean the long nozzle with non-
abrasive cleaning solvent.
NOTE: hardened foam will damage the needle. Remove the front nozzle with a set screw wrench and
check the nozzle for hardened foam. Clean as necessary with an appropriate solvent.
□ Make sure the foam dispensing gun is thoroughly cleaned. If not, foam residue may build up and cause foam to stick inside the gun.
