Fill the container with adhesive without reaching the rim and close carefully. Operate the pump lever until the adhesive reaches the brush, then spread it with regular strokes in a thin, even layer on the surfaces to be bonded. Dispense only the quantity needed, without overusing the pump. To replace the bristles, unscrew or pull out the used brush and fit the new one according to the manufacturer's instructions, checking that it is firmly fixed. At the end of work, clean the brush and spout with the solvent indicated for the adhesive used, to prevent it drying and blocking the passage, and store the glue pot in a cool, dry place away from heat sources. Use in well-ventilated areas and keep away from naked flames.
