Flush Station Service

The flush station serves two purposes. It provides a holster to place the gun into when not
using and it sprays water into the gun to flush out debris between uses.

When placing the gun into the holster, the gun activates a lever connected to the timed valve.
Water spray will start, then turn off between 5-20 seconds, depending how the timer shock is
adjusted.

The timer shock is an oil filled dampener. The rate of dampening is controlled by the
adjustment knob. When the lever is pressed the whole shock moves towards the stem of the
water valve. The shock stem, having stiff movement, pushes in the water valve stem. After
some time, the water valve stem pushes the shock stem backwards enough that the water
turns off.
1) If spray time is too short or too long, turn adjustment knob a small amount and test. Loosen
the lock screw on the knob before moving the knob, lightly tighten lock screw after setting.
2) If removing valve assembly from stainless frame, keep track of the O-ring that is between the
two parts. Confirm that the O-ring is in the pocket of the valve block when reassembling.
3) If the timer shock is screwed into the slide block too far, the water may not stop. If the shock
is not far enough, that water may not start.
