1) If the boom fails to fall into a level position, adjust position A; if the boom fails to be lifted upright,
adjust position B. See Figure 3-2A.
2) If the boom shakes during falling or lifting, adjust position C. The shaking that occurs during lifting is
caused by the overlarge spring force. In this case, loosen the screws. If the boom shakes during
falling, tighten the screws. See Figure 3-2B.
3) Use the motor handle to lift the boom in the case of a power failure, See Figure 3-2C.
