NOZZLE INSTALLATION AND ADJUSTMENT OF RADIUS.

1. Up the turret to have access to the nozzle with the hand or insert the Hunter wrench in the hole, turning 90º and throwing upwards.

2. Relax the arc adjustment screw (distance in pic. 1). If the nozzle is already installed, you can remove it by throwing the nozzle by the "ears" with pliers or briefly turning on the water.

3. Slip the desired nozzle into the socket. Note that the socket is angled up 25º. The "ears" must be placed to make that the screw passes by the middle of them. Tight the attachment screw.  The arrow on the rubber cover of the head indicates the location of the nozzle and direction of the water flow.

4. To increase radius turn left the screw, to decrease it turn right.

5. If with the screw adjustment you cannot obtain the desired radius, you must use another nozzle: if you want a higher radius, install a bigger nozzle (you will increase too the precipitation rate); on the same way, for a lower radius, install a smaller nozzle, so the precipitation rate will be reduced.

ARC ADJUSTMENT

The arc adjustable heads are preset approximately 180º from factory. Even the heads can be adjusted when they are working, we recommend that the first adjusts be made before installation.

1. Using your hand (pic. 2), rotate the nozzle turret to the left till his stop, completing in this way the head rotation.

2. Now turn right to the stop. THIS IS THE FIXED SIDE OF THE ARC.
   Keep this position for any arc adjustment. The right stop does not change.

3. Insert the Hunter wrench by the key-end (or an Allen key of the same measure) into the arc adjustment socket (see pic.1/pic.3). While holding the nozzle turret at the right stop, turn right the wrench to increase the arc or turn left to decrease it. With every complete turn of the wrench, the arc will vary on 90º. When you reach the maximum or minimum arc of the nozzle, the wrench won't turn and you could hear an indicative sound.

ALIGNMENT OF THE RIGHT SIDE (FIXED) OF THE IRRIGATION SECTOR.

If the right side of the irrigation sector were not well aligned, we would have a zone wet and another dry. The adjustment can be made of two ways:

1. Turnings left or right the body of the sprinkler and the down accessories. This operation could require remove the land around the sprinkler to move his body.

2. Unscrewing the topside counterclockwise and removing the inside part of the sprinkler. Turn right the head of the nozzle, check the inside of the sprinkler aligning the nozzle over the right side of the zone you wish to irrigate (pic.4) and screw again the inside part keeping the chosen position. The right side is already aligned.
