operation. Accept direction from only one person. However,
obey a stop signal from anyone in the vicinity. All other non-
essential personnel should be cleared from the area.
Failure to position wood blocking directly under bolt hole
locations before removing the shipping/storage container
cover will cause unnecessary pressure on bolts and damage
