Pivoting The Outlet; Rotating The Waterway - Task Force Tips HEMISPHERE Instructions For Installation, Operation And Maintenance

5.5.2 PIVOTING THE OUTLET

The outlet is preceded by a double ball pivot that
incorporates a synchronizing mechanism. Each
pivot is capable of 40 degrees of rotation, resulting
in a total of 80 degrees of sweep Figure 5.5.2. The
80 degree sweep is centered 40 degrees from the
rotating monitor body waterway centerline, allowing
the outlet to point parallel to the monitor body
waterway centerline and up to 80 degrees away from
the centerline.
The synchronizing mechanism allows the pivot
nearest the outlet to be pointed off of the axis of the
pivot nearest the monitor body by taking up the part
of the reaction force that would tend to rotate the pivot
nearest the monitor body.
See Section 9.0.1 on page 26 for synchronizer
maintenance and wear pad repair/ replacement
information.
To lock the trajectory in position while flowing, hand
tighten the lock knob by turning it clockwise. Do not
use a wrench, tool, or cheater bar.

5.5.3 ROTATING THE WATERWAY

The waterway through the monitor body is attached to a double crank shaft by a worm gear and can be rotated a full 360 degrees.
The crank arms come in a standard configuration where the holes closest to the knobs attach to the shaft, and the two crank arms
are rotated 180 degrees to each other. The force required to rotate the crank can be reduced by removing the screws holding the
crank arm, and moving the crank shaft from the bore closest to the knob to the bore furthest from the knob. Either of the crank arms
can also be rotated 180 degrees to make both cranks aligned, if preferred.
