Tank
Draining Material
Pump material out of the melter.
CAUTION: Do not feed charred material through the applicator. Particles can
block the gun. Instead unscrew hose (Refer to section Installation).
Cleaning Tank by Hand
Cold material can usually be peeled off of the sides of the tank (Fig. 5‐12). If
necessary, first heat tank to material softening temperature
(approx. 70°C/158°F, depending on the material).
NOTE: The inside of the tank is release coated. Do not use metallic tools to
clean. Do not use wire brushes! This could damage the release coating.
Retightening Fixing Screws
Heating and cooling that occurs during daily operation can cause the fixing
screws to loosen. Retighten screws as indicated in the table.
NOTE: Retighten fixing screws only using a torque wrench and when the
melter is cold.
If the grid and reservoir are to be separated: When releasing the fixing
screws, note the position of the washer and the spring washers in relation to
one another and restore when reassembling.
