When two or more magnetic ways are used, first secure one of the magnetic ways only, and then install the
coil assembly in the available space. If using one magnetic way only with insufficient space to extend the
linear guide up to the position of the coil assembly, temporarily mount a dummy linear guide in line with the
magnetic way's.

2. Insert a thin nonmagnetic (preferably resin) sheet (approximately 0.5-mm thick) in the air gap between the
coil assembly and magnetic way, and move the coil assembly toward the magnetic way.
Make sure that hands or tools are not jammed due to the magnetic attraction from the magnetic way when
the coil assembly approaches the end of the magnetic way. When the air gap between the coil assembly and
the magnetic way is fixed, the nonmagnetic sheet is not required. (Refer to the table of dimensions in step
1.)
3. Move the coil assembly back and forth several times over the magnetic way from end to end, making sure
that the coil assembly is not touching the magnetic way and that no foreign objects (such as magnetic par-
ticles) are present. Use a nonmagnetic (brass or stainless steel) gap gauge to check that the air gap
between the coil assembly and the magnetic way is even.
