CRACK PRO® HEATED HOSE MACHINE
OPERATING INSTRUCTIONS
APPLICATION OF MATERIAL
DO NOT MOVE THE HOSE UNTIL IT IS AT APPLICATION TEMPERATURE
8. Once the material in the tank is completely melted and the
desired application temperature is reached, it is time to fill
cracks.
9. Detach the hose from its storage holder, swing the boom into
position. Under no circumstances must the hose be bent or
kinked; this will destroy the hose.
10. Check to see that the pump switch located on the
temperature control box is in the forward position, place the
wand applicator head over the crack, and press the pump
activation switch on the wand. If no material comes out after 10
seconds, possibly the end of the applicator is plugged and may
need cleaning.
11. Depress the pump activation switch for as long as
necessary to keep the applicator full without overflowing it.
With some experience you will know how far the material in the
applicator head will go.
12. The speed of both the agitator and material pump motors
can be fine-tuned by adjusting the speed control knobs on the
electro-hydraulic solenoid valve block.
13. The oil temperature controller should be set for 475°F.
14. The material temperature controller should be set for
380°F a mid-range of the recommended pouring temperature on
your products container.
15. The hose temperature controller should be set for 350°F.
16. Keep the voltmeter at 90-100 volts while operating the
hose. This is achieved by the engine throttle, on the air unit
only.
17. On an extremely cold and or windy day, all of the
temperature settings may have to be increased to make up for
heat losses.
See the temperature control page for instructions on how to set the controllers.
