Introduction
The FLX34 and FLX54 series full-circle rotary sprinklers are
designed specifically for golf course applications.
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
installation and start-up procedures. Please observe all Warnings
and Cautions when installing and operating this equipment.
Features
• Full circle (360°) arc coverage

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. -

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. Servicing Sprinkler Mechanism 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. - Page 9 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.
