5.9 Dispensing the Material
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.
Important:
Some difficulty may be encountered when starting up on cold days.
Although the wand is designed to heat the material all the way down to the tip, on cold
days you can place the tip of the wand into the shoebox to facilitate material melting in
the valve. Insert the wand tip for only a short time before proceeding.
1
When the material and hose have 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, depress trigger on the wand and slowly increase
pump speed until the pump motor starts to turn.
4
Adjust the pump speed for the desired flow rate for the application. The rate of flow
may be varied while the pump is running.
CAUTION
Never open flow control more than 2 full turns when using an electric hose as this will
cause premature material pump wear.
Important:
It may be necessary to use the recirculation with the electric hose anytime
the machine is not going to be used for more than 5-10 minutes when the ambient
temperature is below 40°F or not being used for 20-30 minutes in warmer weather.
This is critical after material is up to operating temperature and burner is running
intermittently, the oven will cool and all material in the plumbing and pump will solidify.
To get the oven hot enough to start pumping again, add several blocks of sealant to
lower the material temperature enough to cause burner to ignite. This may not be an
option if the tank is already full.
