Introduction
The Orbit Brass Impact Sprinkler on Tri-point Step Spike is engineered for efficient watering of large areas. Its robust design ensures dependable performance with uninterrupted water flow, even when utilizing dirty or reclaimed water sources. This manual provides comprehensive instructions for setting up, operating, and maintaining your sprinkler to achieve optimal lawn care.
Product Overview
The Orbit 56946 Lawn Sprinkler is designed for durability and wide coverage. It features an all-metal construction, including a heavy-duty brass impact head and a zinc tri-point step spike for stable ground insertion. The sprinkler offers adjustable coverage from partial to full 360-degree watering, with customizable settings for spray distance and water droplet size.
Key Features
- Large-Area Coverage: Capable of spraying up to a 90 ft. diameter, covering approximately 6,360 sq. ft. when set to a full circle.
- Heavy-Duty Brass Construction: Built to withstand high water pressures and severe weather, resisting breaking, rusting, or failure.
- Adjustable Coverage: Easily transition spray coverage from a partial section to a full 360° watering pattern.
- Customizable Settings: Utilize the deflector shield and diffuser screw to modify the water stream and adjust the spray distance radius.
- Anti-Backsplash Arm: Enhances the sprinkler’s ability to maintain a consistent spray pattern and desired area coverage.
- Flow-Through Outlet: Allows for connecting multiple sprinklers in a series to expand your watering coverage based on available water pressure.
- Stable Design: The zinc, tri-point spike can be easily inserted into soil or turf, ensuring the sprinkler remains anchored during operation.
- Durable Construction: The step spike is made with quality zinc materials for long-lasting use across multiple seasons.
- Clog Resistance: Features a flow-through design that resists clogging, making it suitable for use with secondary water sources.
Setup Instructions
Follow these steps to set up your Orbit 56946 Lawn Sprinkler for immediate use.
- Attach Hose: Connect your garden hose to the sprinkler's inlet. Ensure a tight connection to prevent leaks.
- Position Sprinkler: Place the sprinkler in the desired watering area. Step firmly on the zinc tri-point spike to secure it into the ground.
- Adjust Coverage Arc: The sprinkler features two collars at its base. Adjust these collars to set the desired watering arc, from a partial circle to a full 360-degree rotation. The trip pin will hit these collars to reverse direction.
- Adjust Spray Distance/Pattern:
- Deflector Shield: Use the deflector shield at the top of the sprinkler to adjust the height and distance of the water stream.
- Diffuser Screw: A screw pin is located near the nozzle. Turning this screw in will disperse the water, creating a softer, more diffused spray suitable for new lawns or delicate plants. Turning it out will create a stronger, more focused stream for maximum distance.
- Full 360-Degree Operation (Low Pressure): If you have low water pressure and desire a continuous 360-degree spray without the sprinkler reversing, you can flip up the trip pin. This allows the sprinkler head to rotate freely without interruption.

Operating Guidelines
For optimal performance, consider the following guidelines during operation:
- Water Pressure: The sprinkler performs best with adequate water pressure. Low pressure may reduce spray distance and rotation speed.
- Connecting Multiple Units: Utilize the flow-through outlet to connect additional Orbit sprinklers in series. Ensure your water pressure is sufficient to support all connected units for effective coverage.
- Wind Conditions: In windy conditions, the spray pattern may be significantly affected. Consider watering during calmer periods to ensure even distribution.
Maintenance
Regular maintenance will extend the life and efficiency of your Orbit Lawn Sprinkler.
- Cleaning: Periodically check the nozzle for any debris or mineral buildup that might obstruct the water flow. Use a small brush or needle to clear any blockages.
- Inspection: Before each use, inspect the sprinkler head and spike for any signs of damage or wear. Ensure all moving parts operate smoothly.
- Winterization: Before freezing temperatures, disconnect the sprinkler from the hose and drain all water from the unit to prevent damage from ice expansion. Store in a dry, protected area.
Troubleshooting
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Sprinkler not rotating | Low water pressure, debris in head, trip pin stuck | Increase water pressure, clean nozzle, ensure trip pin moves freely. |
| Uneven water distribution | Nozzle partially clogged, diffuser screw misadjusted, wind interference | Clean nozzle, adjust diffuser screw, water during calm periods. |
| Limited spray distance | Low water pressure, diffuser screw too far in | Ensure adequate water pressure, adjust diffuser screw outwards. |
