Check for Free Movement
After completing the installation of the hoses and
cables, the free movement must be checked by moving
the fifth axis of the robot. The hoses and cables must be
able to move freely without stretching or scratching the
robot arm.
Flush SST Switch 3d Gun Before Using
The SST Switch 3D Gun was tested with lightweight
mineral oil, which is left in the fluid passages to protect
parts. To avoid contamination with oil, flush the SST
Switch 3D Gun with a fluid that is compatible with the
fluid being dispensed and the equipment wetted parts.
Leak Test and Priming for Use
After the SST Switch 3D Gun is completely installed on
the robot, the SST Switch 3D Gun can be tested for
leaks. This procedure also primes the SST Switch 3D
Gun for use.
a. Open the air supply. There must be no sound
from leaking air.
b. Check that the solenoid valves (518), shown on
Swivel Chamber page 32, are working properly
by opening and closing each valve from the
robot pendant and listen to the sound of the
piston in operation.
c. Apply material supply pressure and check for
leakage.
d. Position the SST Switch 3D Gun into a
grounded metal pail and purge all nozzles one
by one until the unit is completely filled with
material and all entrapped air is removed from
the supply system.
