extent necessary to provide adequate working clearance.
All personnel must stand clear during lifting operations. A swinging or shifting load may cause injury or
death to personnel.
Use a chain hoist, jack, or other aid when lifting heavier components. Lifting device should be positioned and
attached to components to remove all strain from mounting hardware, before last hardware is removed.
Discard preformed packings, gaskets, seals, and similar material when removed. Be sure that all traces of
