The size of the toolbox and the bed may need to be modified to accommodate. Please clarify. / On Page 6 of specification, Add line 7 to read:
All top of deck tool box sizes are maximum.
Tool box size may be reduced to accommodate pulling module space requirements.

What should the GPM be set at / If it meets the lifting capacity of the crane, / On page 8 of the specifications under Section “I”, add the sentence “The flow should be set at a maximum of 2200 psi, and the GPM should be set at 6-7.”
7 / 7/12/12 / 7/23/12 / On page 10 of the specifications, under Section 8 – Is an 8mm wire rope acceptable in lieu of 7/16”? It seems that 8mm exceed specs. / Revise Page 10, Line 8 to read:
