Block boom hoist cylinder with suitable bracing material to prevent boom hoist cylinder from
contacting rotary manifold. Failure to follow this caution may result in damage to equipment.
Use a lifting device to lift upperstructure (Figure 6, Item 4) to a height sufficient to clear rotary manifold
(Figure 6, Item 3) and electrical collector ring (Figure 6, Item 2). Lower onto frame. Use suitable bracing material
under boom hoist cylinder (Figure 6, Item 1) to protect electrical collector ring and rotary manifold.
Install eight capscrews (Figure 6, Item 6) and 16 washers (Figure 6, Item 5) on outside of upperstructure
(Figure 6, Item 4).
Weight of boom hoist cylinder is approximately 507 lb (230 kg). Use adequate lifting
equipment to lift and support boom hoist cylinder. DO NOT lift over personnel or let personnel
walk underneath suspended load. Failure to follow this warning may cause injury or death to
Use lifting device to raise boom hoist cylinder and hold it in a vertical position.
