CHAIR LIFT
When working on a chair lift always disconnect the charge transformer from the mains and only reconnect when the chair lift is fully working. The board is sensitive to static charge. To avoid damage, touch a metal surface on the lift to discharge yourself of static charge but do not touch the IC chips. Please handle the board with care. Do make sure you double check the connections to the motor and battery before switching on. Power up delay.		chair lift chair lifts disabled mobility handicapped equipment
