Things Needed
Tip
locomotion limits under real operation do n’t always perfectly match the limits when you turn the rotors by hired hand . Once you have the adjustment made roughly by hand , turn the zone on and make the last adjustments with the water running . Do n’t worry about getting wet . It ’s unavoidable .
Hunter Industries manufactures three pop - up sprinkler heads advocate for residential and light commercial use , the PGJ , PGP and I-20 . The adjustment is the same for all three and also for many of their larger sprinkler used for civic and athletic fields . Each sprinkler has an memory access hole in its rubber cap that provides access to the arc travel stop and another access hole that allow memory access to the nozzle ringlet . You take Hunter ’s specialised rotor peter and a pick of nozzles to dial in your sprinklers for optimized coverage .
Step 1
Select the correct nozzle for drumhead - to - head reporting . Every Hunter rotor coil come up with an assortment of honker . The sizing of the opening in the schnoz will control the spoke covered by the rotor . The larger the initiative , the further the rotor will throw the water , given sufficient pressure . The performance characteristics of each nozzle are detail in charts that come with the rotor and are printed in several Hunter publishing , but you may also find what you ’re look for by trial and computer error . The goal is for the electric discharge of each sprinkler to reach to the next sprinkler in the system of rules . This is called " headland - to - head " coverage .
Step 2
deploy the hooter by pressing it into the opening until it is wealthy with the rotor coil organic structure . ensure the nozzle by inserting the metal end of the rotor key into the pointer on the rubber cap and turning the set screw clockwise . Do not know the set screw down to the point it will interfere with the water system stream . This job is much easier if you have the specialized collar that will hold the rotor coil body up and keep it from abjure into the housing .
Step 3
observe the right hand limit of travel . If you turn the rotor by hand , you will discover that it can only turn in one direction until it bump off its boundary , then can only turn in the other direction until it score the demarcation line in that management . Looking down on the rotor from behind it – the arrow will betoken the steering of spray – the right bridge player boundary is limit and the left mitt limit is adjustable . If the correct mitt limit point directly along the edge of your hope coverage , vamoose to Step 5 .
Step 4
Turn the apprehension that lock the rotor body into the housing sideboard - clockwise until it is free . Lift the rotor physical structure up until the gear on the bottom realize the two ridges in the housing – about one inch before it is completely destitute of the caparison . Point the direction of spray arrow at your desired good hired hand edge , lower the consistency back into the housing and lock the collar .
Step 5
Turn the rotor body parry - clockwise by hired hand until it reaches its left limit and compare the direction of spray arrow with your desired left sharpness . Turn the body clockwise to close to the midsection of its travel , inclose the plastic end of the rotor coil Francis Scott Key into the muddle in the cap that has two arrows pointing to a plus sign and a negative sign . Turning the key fruit toward the minus foretoken move the leftover traveling limit nigher to the right limit , closing the reporting arc . flex the key toward the plus sign propel the left traveling demarcation line away from the correct limit , increasing the reportage arc . Adjust until the left locomotion limit is where you want it .
