To string line your screed, there are a few im-
portant steps that need to be followed.
• Place screed ends on a 2 x 6 or other wooden
type support.
• At approximately 1” out from the leading
edge of the screed blade, drive a nail into the
wooden support. NOTE: Nail should be on the
outside of the wooden support.
• Stretch a line as tight as possible from nail to
nail. Make sure that the nail is contacting each
support at the pint of blade contact.
• NOTE: The supports do not have to be on the
same level.
• Use a short, flat piece of metal or wood as a
gauge block to compare the string to the bot-
tom surface of the screed blade and bull-float
blade.
• The blades should be equal to each other at
each splice. If they are not even, loosen jam
nuts and tighten top pipe coupler as described
on page 33.
