5.8 Machine Start Up for Standard Hose
Step
Action
1
Fully open the exhaust stack.
2
Start the engine. (Refer to the manufacturer’s instructions for the engine).
3
Turn the “POWER” toggle switch in the control box to the “ON” position. The red light
marked “BURNER” will illuminate indicating that the material and hot oil temperatures are
below set point. When the red light goes off this indicates the material or oil temperatures
are up to the set point.
NOTE:
Just because this light is illuminated does not indicate the burner is actually
working.
4
Turn “HOSE SELECTOR” switch to “STANDARD”.
5
Set the heat transfer oil temperature at 450°F (232.2°C).
6
Set the material temperature to 350°F (176.7°C).
CAUTION
If the burner does not ignite the first time, turn the “POWER” toggle switch to the “OFF”
position. Turn the toggle switch to “ON” again; the burner should ignite. If the burner still
does not ignite, refer to
8.0.1 Symptoms: Burner will Not Ignite
malfunction.
Important:
The solid material in the tank melts first around the walls, bottom, and around
the center tower of the tank. The material temperature sensor is located by the wall,
therefore, it is possible that at the beginning of the melting process the indicated
temperature reaches operating value, but the material between the center tower and the
outside wall of the tank is still solid. This is normal, and when the heated hose is ready for
operation, most of the material in the tank will be melted and heated to the proper
application temperature.
7
Allow the heat transfer oil to continue to heat.
8
When the material reaches 275°F (135°C), the mixer light will illuminate which indicates
the mixer can be engaged by turning the toggle switch at the control panel to
“FORWARD” position. If the mixer does not move, allow the material to heat longer.
Note:
Mixer speed is preset at the factory and cannot be adjusted. The mixer cannot be
engaged until the material reaches 275°F (135°C).
CAUTION
Jamming the mixer can cause the hydraulic oil to overheat and damage the machine.
9
The pump light will come “ON” when the material temperature reaches 275°F (135°C)
indicating the temperature interlock will allow material pump operation.
NOTE:
Hose temperature display will not read an accurate pumping temperature until
sealant is being pumped through the hose.
Important:
The oven must be at 300°F (162.8°C) for 20 minutes before attempting to
pump. The oven temperature can be regulated by opening the slide gate to increase
temperature or close slide gate to decrease temperature. Slide gate is located on
passenger side.
