under what condition is this legal? - ANSWER- Manual operation must
be provided
Your helper wired the down direction and final limit switches, now the
car will only travel up, what is the issue? - ANSWER- The down
direction limit was wired incorrectly.

the chain is not. What is the problem? - ANSWER- Oil on the drive
chain
What is the effect when you change a sling angle from 60 degrees to 30
degrees? - ANSWER- More tension, less capacity. Any angle 30 or less
is dangerous
