How do you adjust orbit rotating sprinkler heads?

Turn the head all the way to the left and then all the way to the right. Make the adjustment with the head in this position. Insert the screwdriver or the plastic end of the key into the arc-adjustment hole and turn it clockwise to increase the arc width -- once again, a full turn adds 90 degrees.

Also to know is, how do you change the direction of an orbit sprinkler head?

Insert a flat-head screwdriver into the slot of the screw in the center of the nozzle and turn it clockwise to reduce the spray amount and distance. Turn it counterclockwise to increase them. Adjust the spray pattern on a gear-driven sprinkler using the screwdriver.

Likewise, how do you fix a sprinkler that won't rotate? How to Do It

Disassemble the sprinkler head.
Take off the filter at the bottom of the head.
Rinse the filter in a bucket filled with clean water to wash out debris.
If this doesn't work you'll need to have the sprinkler head replaced.
If it does work, make sure the head is properly adjusted when you re-install it.

Beside above, how do you adjust the water flow on a sprinkler head?

With a screwdriver, adjust the radius screw located on top of the sprinkler head. Turn the radius screw clockwise to lessen the water flow. Turning the radius screw of your sprinkler will introduce friction to your sprinkler nozzle and reduce the amount of water coming into your sprinkler system.

Why won't my sprinklers rotate?

When the water pressure is too low, an inadequate amount of water flows through the sprinkler head and it will not turn. Using a larger backflow preventer in the water line might increase the water pressure enough to cause the sprinkler head to rotate.
