Never leave machine unattended while system power is
on or system is running.
System running is dened as: preheat cycle of the hose
heat, primary heaters, or any pump operation.
Machine operators must be familiar with the component
functions and operation of the machine.
Pre-Operation Check List
A. Check that all ttings are securely tight.
B. Check electrical hook-up (qualied electrician
recommended).
C. Main power switch on Control Box should be
switched to OFF position.
Do not place any part of the body in the path of the
material spray. Do not point the gun at or near other
personnel. Do not look into the Mixing Chamber orice
at any time. Because of the hazardous materials used in
this equipment, it is recommended that the operator use
an air mask, goggles, protective clothing, and other
safety equipment as prescribed by current regulations,
recommendations of the chemical suppliers, and the
laws in the area where the equipment is being used.
Initial Start-Up Procedure
With all material and air lines connected and power
cable attached, the system is now ready for start-up.
Filling The System
1. The system is now ready to be lled with material.
With transfer pumps in place, adjust regulators on
transfer pumps to 30-50 psi or until the pumps begin
cycling, once the pumps begin loading up (cycle rate
slows or stops) increase transfer pump air pressure
to to 100 psi. to ll the system.
If the transfer pumps can not move material adequately
enough to properly prime the system it may be
necessary to start the hydraulic power pack.
a. Ensure hydraulic pressure knob is turned com-
pletly counter clockwise.
Pressure
knob
b. Main air should be on to system manifold.
c. Turn on hydraulic power pack.
d. Flip retract switch to “run” position.
The pumps will begin cycling to completely prime the
system

2. Remove ISO & POLY side blocks from gun.
MAKE SURE VALVES ARE OFF!
3. Place separate clean containers under each indi-
vidual side block. Slowly open material valves
(black arrow forward) on each side block to allow
trapped air to escape the hose and material to ow
into the containers until all air is purged from the
material system.
Remember to dispense one to two gallons of material
to clear the system of grease and plasticizer that was
used during factory testing.
4. Close the manual material valves. Material pressure
gauges should now register approximately equal
pressure.
5. Dispose waste material properly and in accordance
with chemical suppliers instructions and local, state
and federal regulations.
Before re-assembling Side Blocks, lubrication can be
applied by dabbing a white lithium grease into holes in-
side of Gun Front Housing and wiping grease over Side-
Block Seals. Grease will purge itself when air valve is
turned on at Gun and Gun is triggered.
6. Clean and lubricate the side blocks and seals thoroughly
and re-assemble them to the gun. Make certain that the
side block screws are tightend securely.
7. Refer to material manufacturers operating instructions
for proper preparation of material, i.e, mixers, etc.
8. Turn main power Switch to ON position.
9. Turn on hose control:
a. Push in the green button.
b. Press either up or down arrow buttons on the
controller until desired temperature setting
is achieved.

b. Press either up or down arrow buttons on the
controller until desired temperature setting
is achieved.
10. Turn on the ISO & POLY Heaters.
Green Power Button
Turn transfer pump air regulator on slowly. Pumps
should cycle slowly until hoses are full of material.
Straighten hose out at, to avoid uneven heating and
damage to internal wiring of the hose assembly.
11. Turn on Hydraulic Power Pack
Allow enough time for hose to warm up (approx. 30
minutes). Remember that the heated hose does not
have a delta rating. The heated hose’s function is to
maintain the heat generated by the primary heaters
during system operation, and preheat material during
initial start-up. The hose should be set to maintain a
temperature close to the set point of the primary
heaters.
To see the actual temperature of the liquid in the hose,
push the blue button once and release. The actual
temperature will then be displayed for 10 seconds.
12. Adjust temperature to desired setting. ISO and POLY
controllers function exactly the same as the hose
controller.
Allow enough time for the material to be heated
(approximately 3-5 minutes).
13. Slowly adjust hydraulic pressure knob clockwise
on the system to desired pressure.

15. If one side registers considerably more pressure
than the other side, go to the high pressure side
and bleed off some pressure by slightly opening
the manual material valve on the side block over
the container. Bleed pressure until both sides are
approximately the same pressure.
Material will dispense at high pressure. follow all
safety precautions
16. Relieve any excess pressure by triggering the gun.
The Emergency Stop Switch is located on the top
right side of the Box Panel, when depressed, it will
shut down the power to the system. To reset, turn the
“red” push button.
17. The system is now ready for operation.

5. Turn main power switch off.
6. Refer to gun manual for proper Gun maintenance.
7. Reduce Hydraulic Pressure Knob setting to ZERO.
8. Visually inspect entire system for leaks.
9. Turn OFF System.
