    Need help- our pat trap suddenly began windmilling, unable to adjust limit for enough to cure the problem. Full of fluid, any advise will be appreciated

    Look at the rubber brake on the back of the machine and its metal backing.

    i assume in cold weather, you have warmed it up, by letting pump run for 15-20 min? very cold maybe longer

    Marco Polo gave good advise. Check the metal spring behind the rubber on the brake. That's the rubber the throwing arm contacts at the end of the throw. I'll bet it is broken off even with the mounting.


    One of our Pat-Traps did the same thing. It was 60 degress outside and all of a sudden it started windmilling. Comparing the brake spring on one of our other traps confirmed the offending trap's spring was broken.


    A quick call to Rhodeside got us a new spring over night and we were back in business the next day at our registered shoot.


    That Pat-Trap is currently working every Saturday in central Indiana when the temperature is +10 degrees. We do let the hydralic warm up for 30 minutes first. No other heat source is supplied.

    As they said above. Cut on the motor and not the machine. Let it warm up and or keep a heat lamp on it with a timer when you want to use it. It has to warm up. Once it warms up its fine.

    I had a hand control go bad one time and it caused the same problem. Unplug it and try a different control if the brake is ok.

    Check the pull cord all the way to the control box on the rear of the machine for an intermitant short. If the #4 switch bracket is adjusted as far as the slot will allow toward the front of the machine, then the hydraulic valve may be the culprit. Assuming this is NOT a wobble machine, the bottom valve controls the throw arm. Unscrew the knurled caps from each end of the hydraulic valve and remove the spring and small piston/rod and swap the left side for the right side. No oil will leak out when doing this and should take no more than 5 minutes. If this solves the problem, then this fix will likely get you down the road for several months. Eventually you will need to replace the valve at about $150 cost. The valve and the speed it operates is critical to stop the arm on the brake. A slow operating valve will cause the arm to run past the brake. CHECK THE PULL CORD!!!

    This is a classic cold weather related problem with the Pat Trap. Solution: North Hollywood Sportsman's club solved the problem with car oil pan heaters. Golden West out of Sylmar, CA. sells the stick on pads for about $30+ each. Stick the small red pad on to the oil reservoir. I found that 5 inch hose clamps x 2 on each reservoir worked better than the self adhesive. Attach an appliance wire and plug and in 20 minutes of warm up the problem is solved. UNPLUG after warm. Nothing works better as the heat lamps take forwever. PS: Run the moter to circulate the oil. Fred
