CHAPTER 5 CLEANING THE UNIT
1. Cleaning Each Section
Dirty belts and paper path may cause trouble. Clean the machine once a day by removing glue or
paper chips using a cloth moistened with water or alcohol, or a vacuum cleaner. You also need to
change the hot melt glue in the glue tank when its color has changed.
● Make sure that you disconnect the power cord (mains lead) from the wall outlet (wall
socket).
● The inside and outside of the glue tank is very hot immediately after turning off the
power. Make sure that the glue tank is completely cool before you clean the machine.
● Before you use the machine after cleaning, make sure that its surface is completely
dry.
Do not use flammable sprays or solvent inside or near the unit (e.g.
when cleaning the unit).
Such flammable gas may ignite and cause a fire or combustion.
Take precautions against fire and ensure ventilation when using alcohol, and store the
alcohol in a safe place after use. Also note that use of other solvents can damage the
rubber rollers and resin inside the unit, resulting in malfunctions.

If paper chips accumulate on the suction belt, a cover may not be smoothly fed into the nipping
section or it may be damaged.
Suction belt Clean the suction belt while rotating
