Selection and safe servicing

Match part number 102-4003 to the exact sprinkler body diagram before ordering. This is an electric valve assembly; it is not the normally-open hydraulic or Check-O-Matic valve assembly.

• Shut off the water supply and bleed all residual pressure before removing the riser or main valve.
• Toro specifies insertion tool 118-1843 for reinstalling the 1½-inch valve and snap ring.
• Never stand or lean over a sprinkler while the system is filling, operating or being serviced.
