These warning tags (Special Instruction, SEHS7332) are available from your Caterpillar dealer.Assemble certain components of the rake together prior to welding in order to align and install the blade rake.This procedure will require the installer to fit together and hold multiple, piece parts, to the blade simultaneously. This procedure will require the use of a suitable lifting device or devices to position the parts.
