If you do not follow this method, the mandatory operation will cause damage to the glue gun or cause the seam sealant to burst.2.Please do not disassemble the glue gun by yourself.3.Please be careful not to leave any residue of seam sealer or stain on the pushing metal rod, and keep the pushing rod smooth, with appropriate lubricant for smooth construction.4.Please allow the slight color difference caused by the shooting light and 1-3 cm error due to manual measurement, and make sure you do not mind before ordering.
