REACH AND TRAJECTORY

CAUTION
Notes on trajectory graphs:
• Graphs show approximate effective stream trajectory at 30 degrees elevation in no wind conditions. Distance to last water drops
approximately 10% farther.
• To estimate trajectories at elevations other than 30 degrees, refer to document LTT-135, available at tft.com.
• Trajectories shown are for water. The addition of foam is expected to decrease the reach by 10%.
• Tail or head winds of 20 MPH (30 KPH) may increase or decrease the range approximately 30%.

Dents or nicks in the nozzle tip can seriously affect the stream reach or pattern, which may increase
the risk of injury due to exposure. Care must be taken to avoid dents or nicks in the nozzle tip.
