from the bottom up while checking the belt or chain for proper tension. Ensure the upright components are
square to each other and the base when completely tight.

The upper capstan chain should be adjusted every 6 months to a year depending on usage. Check for
excessive chain looseness by removing the capstans, removing the chain cover to expose the chain. Check the
chain by pressing on the chain. The chain should be tight with a small deflection of 1/32 of an inch with
moderate hand force. While the chain cover is off check the torque on the setscrews of the chain sprockets and
capstan drive pulleys.
7.9) Vertical drive belt adjustment
Remove the lower vertical belt cover. Adjust the lower capstan head upwards to obtain approximately 1/8 inch
deflection with a light hand force.
