Breaks up the stream of water for more close-in watering. Shortens dis-
tance of the stream (throw) up to 25% of total throw. Screw clockwise
into the stream to produce misting and shorten throw. Turn counterclock-
wise until totally out of stream for maximum distance (unadjusted throw).
Reduces length of the stream and redistributes water. Tilt downward into
stream to deflect water. May be used in conjunction with diffuser screw
for maximum throw reduction.
Some plastic models have a dial on top marked for minimum and maxi-
mum distance. Turning the dial will cause modification of the stream of
water and distance of throw as indicated on the dial. This feature serves
the same purpose as the distance control flap found on other models.
Used to adjust degree of arc sprinkler will rotate. Position one arc ad-
juster for each side of the desired arc. Several types of arc adjusters are
available depending on the model of your sprinkler. Generally, plastic
models move by just a push of the thumb. To adjust the metal models,
pinch the ends of each metal adjuster together before sliding into posi-
tion.
Used to determine part or full circle operation. Flip or bend the trip pin
upward so it does not hit the trip collar for full circle operation. Pin should
be downward for part circle operation (then slide arc adjusters into posi-
tion to set degree of arc).

  • Page 2 IMPACT SPRINKLER TROUBLESHOOTING Through many years of experience, we have found that conditions which most often interfere with the proper operation of impact sprinklers are the use of any lubricants (other than water), low water pressure, foreign materials in the irrigation water, and excessive damage or wear to sprinkler parts. Any one or a combination of these factors can cause the sprinkler to stop rotating completely or ro- tate to one side and fail to return.
