Loosen the three screws which allow the row guide to move up or down.
Part the nap of the carpet to be trimmed with a row nder or separator.
Set the base of the Seam Cutter on the carpet with the extended row
guide dropping into the parted row. With some downward pressure on
the handle of the tool, press the row guide down to the bottom of the row.
Once the row guide depth is set, retighten the three screws.
NOTE: A properly adjusted row guide will ride on the bottom of the row
and the base will be at on the face of the carpet. The base should not
teeter back and forth on the row guide. If it does, shorten the depth of the
guide until there is no rocking, yet the row guide still contacts the bottom
of the row.

thickness of the carpet’s backing. Make test cuts, and then any necessary adjustments, before proceeding.
NOTE: If the carpet being installed has an attached backing, additional
blade depth is available by the following: insert the thumbscrew in the
middle hole COMPLETELY ABOVE the slotted razor blade. Adjust the
slotted razor blade to desired depth and tighten. WARNING: It is not advisable to extend the blade more than 3/4” beyond the base.
