Manufactured from durable, high-strength engineering plastic and
stainless-steel components, these sprinklers incorporate many
innovative and time-proven features for lasting, maintenance-free
operation.
Prior to installing the sprinkler, read through the recommended

Use Toro swing joints to connect the sprinklers to the lateral/main line pipe. Figure 1 Toro swing joints provide swivel joints that allow the sprinkler body to be easily positioned to finished grade and prevents pipe breakage by providing the flexibility to allow downward movement if the sprinkler is run over by heavy equipment. -

25' above controller elevation or 70' below controller elevation * - All hydraulic connections on Toro valves are 1/4" insert type. - Control line pressure must be equal to or greater than mainline pressure. - Control line pressure range is 40 to 150 PSI. - Page 5 Winterizing the irrigation system is required in freezing climates to prevent damage from water expansion when it freezes. Following are three key points for successfully winterizing the system, however, Toro provides a complete “Winterization and Pressurization Guide” (P/N 373-0849) that is available from your local Toro Distributor.

Pilot Valve Operation (Electric Models Only) The pilot valve controls the operation of the main valve located in the base of the sprinkler body. The main valve is operated by the release of water metered through the pilot valve when it is activated 100 PSI either manually at the sprinkler or by the irrigation system controller. -
Page 8: Servicing Procedures
Refer to the Troubleshooting Procedure in this manual in the event of a malfunction. Some special tools are required for disassembly and/or maintenance of the sprinkler and are available from your Toro dealer. - Page 9 Step 8 – Remove the cap screw (1) and cap (2). Note: During reassembly, ensure the cap is correctly installed with the Toro Logo positioned over the main nozzle (12) and the snap ring is correctly installed and fully seated in the sprinkler body.
- Page 10 Servicing Main Valve WARNING! If the valve snap ring is difficult to remove, residual water pressure may be remaining in the system. To prevent possible serious injury due to valve being ejected upward under pressure, confirm the following conditions exist prior to removing the snap ring and valve. A.
- Page 11 Step 10 – Thoroughly clean and inspect all parts. Replace damaged parts as necessary and reassemble in reverse order. Note: For service part numbers, refer to www.toro.com and click Parts. Select the “Irrigation” category and search for “Pilot Valves”. Flushing Sprinklers WARNING! Never stand or lean over the sprinkler while the irrigation system is being filled, during manual or automatic operation or when performing sprinkler service procedures.
