Instructions for removing the nozzle retention screw, pulling the riser, and installing a new nozzle.
The nozzle retention screw also acts as a break-up screw to adjust the spray distance.
Rotate the nozzle turret to the fixed right start position, holding it for adjustments.
Realignment of the right arc stop to prevent overspray onto unintended areas.
Increase arc by turning Key (A) clockwise in slot (L); decrease by turning counter-clockwise.
Thread sprinkler onto pipe, bury flush to grade, and avoid mixing zones with pop-up sprays.
Remove the sprinkler assembly from the housing can to access and clean the filter.
Use air below 30 PSI, introduce gradually, and limit run time to prevent internal damage.

The RPS® 50 Gear Driven Sprinkler is a robust irrigation device designed for efficient and adjustable watering. It comes pre-set with a 40° arc and a #1.5 nozzle, offering a good starting point for various landscape needs. The sprinkler's design emphasizes user-friendly adjustments for both nozzle changes and arc settings, ensuring precise water distribution.
The RPS® 50 is a gear-driven sprinkler that delivers water over a specified arc, which can be adjusted from 40° to 360°. Its gear-driven mechanism ensures smooth and consistent rotation, providing even water coverage. The sprinkler features a fixed right start and an adjustable left stop for arc customization. Water is propelled through interchangeable nozzles, allowing users to select the appropriate spray pattern and distance for their specific watering requirements. The internal components are designed for durability and ease of maintenance, with a removable filter to prevent clogging and ensure optimal performance. The device is intended for outdoor irrigation, delivering water efficiently to lawns, gardens, and other landscaped areas.
The process of changing a nozzle is straightforward. First, the nozzle retention screw (B) is removed using the provided key (A) by turning it counter-clockwise. Once the screw is out, the riser assembly needs to be pulled up. This is achieved by inserting the key (A) into the keyhole (C) on the nozzle turret (D) and turning it 1/4 turn to secure the key, then firmly pulling up the entire spring-loaded riser to expose the nozzle socket (E). With the riser held, the old nozzle can be removed. This can be done either by turning on the water (while wearing safety glasses) or by pulling outward on the nozzle wing (F) with needle-nose pliers. To install a new nozzle (G), it is pressed into the nozzle socket (E), ensuring the nozzle number is visible and the nozzle wing (F) is up. Finally, the nozzle retention screw (B) is re-installed. This screw also functions as a break-up screw, allowing for adjustment of the spray distance.
The RPS® 50 has a fixed right start and an adjustable left stop. To begin arc adjustment, the nozzle turret (D) must first be positioned to its "right start." This involves rotating the turret counter-clockwise to the left stop to complete any interrupted rotation cycle, then rotating it clockwise to the right start. This fixed right start position is crucial for all subsequent arc adjustments.
If the right side of the arc is not properly aligned, it can be realigned using two options. Option 1 involves repositioning the entire housing can (K) on the fitting by turning it left or right. This may require temporarily removing soil around the sprinkler to grip the can. Option 2, a more involved method, requires removing the internal riser assembly (J). The top is unscrewed counter-clockwise, and the internal sprinkler assembly (J) is removed from the can (K). With the nozzle turret (D) at its right start, the riser assembly is repositioned so that the nozzle arrow points to the desired start position. The riser assembly is then replaced in the can and the top is screwed back on. This realigns the right arc stop, allowing for left arc adjustments.
Adjusting the left (variable) side of the arc involves either increasing or decreasing the arc. To increase the arc, the key (A) is inserted into the arc set adjustment slot (L). While holding the nozzle turret (D) at the right start, the key is turned clockwise. Each full 360° turn of the key increases the arc by 90°. The arc can be adjusted between 40° and 360°. The key will stop turning, or a ratcheting noise will be heard, when the maximum arc of 360° is reached. To decrease the arc, the key (A) is inserted into the arc set adjustment slot (L). While holding the nozzle turret (D) at the right start, the key is turned counter-clockwise. Each full 360° turn of the key decreases the arc by 90°. The arc can be adjusted between 40° and 360°. The key will stop turning, or a ratcheting noise will be heard, when the minimum arc of 40° is reached.
When installing, pipe dope should not be used. The sprinkler is threaded onto the pipe and then buried flush to grade. It's important to note that gear-driven sprinklers and pop-up sprays should not be installed on the same watering zone to ensure optimal performance.
Regular inspection and cleaning of the filter are essential for maintaining the sprinkler's performance. To access the filter, the top is unscrewed, and the complete sprinkler assembly (J) is lifted out of the housing can (K). The filter is located at the bottom of the sprinkler assembly and can be easily pulled out, cleaned, and re-installed. This prevents debris from clogging the nozzle and ensures consistent water flow.
For areas subject to freezing temperatures, proper winterization is crucial. When using an air compressor to remove water from the system, several precautions must be observed. The air pressure should not exceed 30 PSI. Air must be introduced into the system gradually to avoid sudden air pressure surges, which can damage the sprinkler. Each zone should run for no longer than 1 minute on air. Sprinklers turn 10 to 12 times faster on air than on water, and over-spinning rotors on air can cause damage to the internal components. Adhering to these guidelines will help preserve the sprinkler's integrity and extend its lifespan.
