    Having a slight problem with the BEOMAT 400 that is in one of our trap fields. The trap is a singles only with wobble capability and throws excellent targets. We bought it used and have never had a problem with it that prevented us from using it. However it does have one quirk that has been driving us nuts trying to track it down. At first it appeared that at random times the trap would shake. The first thought was that the drive belt was slipping or that the area around the belt and pulleys was full of bird pieces. Checking the belt tension and area around the belt and pulleys showed no problems but it allowed me to watch the action of the interrupter and note that the shakes came only when the interrupter micro switch was supposed to stop the movement. Not on every lobe and not always on the same lobe. Most times the movement stopped and started just like it was supposed but occasionally the jerks happened instead. The micro switch measures good and does not seem to have any intermittent spots and the arm is being fully operated on each lobe. My question is does the interrupter control the motor or does it control the clutch while the motor runs constantly. Secondly does anyone have an adjustment procedure for the clutch documented anywhere. THANKS

    The interruptor controls the clutch only, the shake that you are having comes fron the linkage from the machine to the pulley. So the shake will show up when there is a little slack in the angle adjusting rod. Ck to see how much movement you have back an forth when the machine is off. The ends of the rod have bearings that wear and get loose.

    That was one of the items we checked along with taking the angle rod off and checking the movement of the plate. But I will go back and look again. Different day different eyes can't hurt. THANKS
