FLOW CONTROL VALVE
DWG-M01328
(12915)
The fl ow control valve controls how fast the
gutter broom raises by restricting the fl ow of
oil from the base end port of the gutter broom
cylinder. Set broom retraction speed from 2.5 to
3.0 seconds. Faster speeds can cause torque
motor seal damage. The fl ow control valve has
an adjustable screw used to set the upward
speed for the gutter broom. Before the screw
can be adjusted, a jam nut must be released to
unlock the screw. To slow upward speed of the
gutter broom, turn the screw clockwise using
3/16 Allen wrench. Once the desired rate of
ascent is obtained, tighten jam nut and reinstall
cap.
