8.4 Pump Troubleshooting
Symptom: Material Does Not Dispense When the Pump is Activated 8.4.1
Step Possible Cause If . . .
1 Start Troubleshooting at the control box.
Is the Hose Temperature Display at or above
325°F?
• Yes, go to Step 2.
• No, continue to allow the machine
to heat. (Make sure the Hose dial
is set at the operating
temperature.)
2 Is the red "Pump" light "ON"? • Yes, go to Step 3.
• No, allow the hose to continue to heat.
3 With the wand in the shoebox, pull the wand
trigger and look at the material pump shaft chain
coupler.
Is it spinning clockwise? (Remove the chain
guard if necessary.)
• Yes, go to Step 5.
• No, adjust the material flow control to
increase the flow.
• No, go to Step 4.
4 Inside the control box and under the front panel,
find the relay cube for the pump. It is found near
the middle, left-hand side of the box. It is a clear
yellow cube with a green button facing the top of
the control box. When you press this button,
material should dispense from the wand, so be
careful.
Does the material pump shaft coupler turn when
you press the green button?
• Yes, this tells you that everything
from the cube relay to the hydraulic
manifold is working properly, your
issue is inside the hose and wand.

find the problem.
