depends on mast section 3, platform to base frame adjustment, this adjustment can affect sequence cable adjustment.
Also as cable stretches, more spring compression will be required. If mast section 3 is adjusted properly and sequence
cable cannot be adjusted to remove slack, the sequence cable will need to be replaced due to stretching.
