g) When the products contained in the hoses have reached working temperature, press
the ISO and RESIN buttons located under the HEATERS/CALENTADORES display.
Both LEDs will light up.
WARNING!
To avoid excess pressure in the heating hoses, wait for the products
contained in the hoses to reach the required temperature before starting the hydraulic
system.
h) Press the MOTOR button. The LED will light up.
Once the above operations have been completed, you now have to check the direction of
rotation of the motor. Proceed as follows to make sure the motor is rotating in the clockwise
direction:
i) Rotate the hydraulic pressure regulator in the anticlockwise direction as far as it will go.
j) Rotate the power switch to the ON position. The upper pilot light goes on.
k) Press the CONTROL/POWER button.
l) Position yourself so that you can see the motor fan on the side of the unit. Press the
MOTOR button to start the motor, then press it again to stop the motor. Check that the
fan blades are turning in the clockwise direction.
m) Rotate the hydraulic pressure regulator in the anticlockwise direction as far as it will go.
n) Rotate the power switch to the ON position. The upper pilot light goes on.
o) Press the CONTROL/POWER button.
p) Press the NORMAL button. The LED will light up. One of the direction indicator lights
comes on and the proportioning pumps begin to operate.
q) If necessary, rotate the hydraulic pressure regulator to reach the required pressure, and
check the pressure of each proportioning pump on the respective pressure gauges at
the unit’s outlets.
The hydraulic circuit should be regulated to ensure that the
unit’s output pressure never exceeds the working pressure of
the product hoses fitted to the unit.
r) Allow the air and oil to escape from the recirculation tubes until there is no more
residual oil and the air has stopped gurgling.
s) Close the manual recirculation valves for each product.
t) Remove any product residue from the recirculation tubes and re-connect them to the
tanks.
u) Slowly increase the hydraulic pressure to check for any product leakage at any point in
the circuit.
v) Rotate the power switch to the OFF position. All displays will switch off.
w) Place the gun in the coupling block.
x) Rotate the power switch to the ON position. The upper pilot light goes on.
