Blue Boards with contactor were installed a few years ago. Batteries are good.
All functions of the lift work.
Problem: Each time the "Up" and "Any Speed" button are pressed for the man basket, the contactor pulls in, the pump motor starts and then the basket moves very quickly for a split second and bounces back. The initial impulse is hard enough to spill paint out of a bucket. Once the initial jerk is over, the basket moves as it should. If you stop after a short movement, it does the same thing if you start again. The other arms both work fine. The basket cylinder is single acting. The initial pulse from the pump extends the cylinder a 3 or 4 inches. The baskets swings out then returns and bounces a couple of times. It acts like there is air on the cap end of the cylinder that compresses easily and then it bounces. Help.....
