Step Action
WARNING
Put on protective clothing, gloves, hard-soled shoes, and face shield or safety glasses
when operating or filling this machine. Read the entire manual before operating the
machine.
Never point the wand at any part of the body or at any other person. Hot material can
cause severe burns.
1 When the material has reached manufacturer’s application temperature, you are ready
to dispense material.
2 Turn the pump speed control to the lowest setting by turning the speed control knob
fully clockwise.
3 Insert the wand tip into the shoebox, open the ball valve on the wand and adjust the
control valve to get close to the desired material flow for the application.
4 Open recirculation valve to get the desired flow rate.
5 This method of operation will give maximum pump life. If the sealant does not flow
from the applicator wand, close hand wand valve and place hose and wand back into
the oven to allow the sealant to become more liquid, and then repeat procedure.
6 Once sealant is flowing freely, reverse pump and install desired sealing tip or disk and
you are ready to begin sealing. See Section
10.0 Tools and Accessories for other
sealing tips and disk.
CAUTION
Extreme care should be taken when changing or installing sealing tips. Always
engage pump reverse if sealant is hot. Hot sealant can cause severe skin burns.
5.10 Shutting Down and Cleaning Out the Machine
When shutting down the machine for the day, Crafco recommends leaving the melter about half full
with material. This will give a fairly rapid heat up rate in the morning, but allows enough material to
start dispensing right away when the material becomes molten.
