DELIVERY PILE BOARD WILL NOT RAISE (cont). l WARNING HIGH VOLTAGE When working on high-voltage components, always have another person present, keep one hand away from equipment to reduce hazard of current flowing through vital organs of body. Remove all jewelry from fingers, wrists, and neck prior to working on electrical components. Failure to do so may result in death or serious burns. Step 1. Step 2. Step 3. Step 4. Check chain and sprocket drive for binding, wear, broken or damaged parts. Repair or replace (para. 2-64). Check for bound or frozen delivery pile motor. Replace motor (m5) (para. 2-64). Press pile down pushbutton (b23). If pile lowers, go to step 4. If pile does not lower, go to step 7. Using a multimeter set to ohms range, check for continuity at points 21 and 22 of pile up pushbutton (b22) and pile down pushbutton (b23) and points 13 and 14 of pile up pushbutton (b22) and pile down pushbutton (b23). If continuity is present, go to step 5. If no continuity is present, replace faulty pushbutton (para. 2-94). NOTE In step 5, perform continuity tests in sequence of listed components. Step 5. Using a multimeter set to ohms range, check for continuity between the points listed below for the following components. Limit switch (b209): Across switch terminals Limit switch (b39): Across switch terminals Relay (d59): Points 43 and Point 44, Point A1 and Point A2 (with relay button pressed) 2-44
