35. Continue to install cable into sub-duct. The operator wearing work gloves should hand
guide the cable into the blowing machine through a dry clean cloth to prevent any debris
on the cable entering the blowing machine and to ensure the cable enters the machine
inline with the tractor drive belt without and bending or deviation.
36. When approximately (650 ft.) 200 meters of cable
have been installed into the sub-duct or the hy-
draulic pressure begins to rise, “open” the air valve
slowly
to allow the compressed air to enter the air
chamber. This assists the installation of the cable
through the duct.
37. When the cable has reached its destination, the
worker stationed at the other end of the duct will
notify the operator to stop the machine by turning
the hydraulic valve to the off position.
38. Turn the speed control knob to the “MIN” (counter
clockwise) and press the reset button.
39. Turn the air valve to the “closed” position. Allow the
air pressure to exhaust. This may take several min-
utes as there may be a considerable amount of air
in the sub-duct. Do not open the air chamber until
the air pressure gauge reads Zero.
