Final Installation
1. Reinstall the fenders.
2. Test the hoist to make sure none of the cables at risk of being pinched, stretched or cut when it is raised and
lowered.
3. Test the hoist to make sure the scale reads positively with applied weight. If positive weight is not
displayed, it is possible that the load pins or a load pin are not in the correct position and reading
backwards. Pin position can be changed by rotating 180 degrees.
