Arc Adjustment Procedure ________________________________________________________
DUE TO THE HIGH OPERATING PRESSURE, NEVER STAND OR LEAN DIRECTLY OVER THE TOP OF THE
SPRINKLER OR COME IN CONTACT WITH THE SPRAY. FAILURE TO COMPLY MAY RESULT IN SERIOUS INJURY.
The DT35 and DT55 sprinkler models can be operated in full-circle or part circle operation. In part-circle operation, the sprinkler arc
can be adjusted from 40°– 330° (factory preset at 180°). The left side of the arc, located at the end of the counterclockwise rotation, is
non-adjustable (fixed). Therefore, all arc adjustments, whether increasing or decreasing, will change the right side of the arc, located
at the end of the clockwise rotation. When full-circle (360°) operation is selected, the sprinkler will rotate in a clockwise direction only.
1. Insert the multi-purpose tool (P/N 995-83) into the slot provided in the top of the cap. Pull the riser assembly up, then grasp the
assembly to hold it in the popped-up position. See Figure 3.
2. Find the sprinkler left stop by rotating the turret counter clockwise until it stops. The left stop indicates the fixed stop of the arc.
See Figure 4.
3. Find the sprinkler right stop by rotating the turret clockwise until it stops. See Figure 5.
Note: If the sprinkler is set at 360° (full-circle), there will be no stop when turning clockwise.
4. Adjust the arc while the turret is pointing at the right stop. Hold the sprinkler riser firmly while pressing the release on the
adjustment band. Rotate the turret counterclockwise or clockwise to the desired right stop. See Figure 6.
Figure 3
The adjustment band of the DT35 and DT55 have markers at predetermined arcs. By aligning the adjustment band indicators to the
turret arrow, you can set the sprinkler arc to 90°, 180°, 270° or 360°. See Figure 7.
