The magnetic way's magnets exert strong magnetic attraction. Make sure that any steel bolts or wrenches being used are
kept away from the magnets. Always use bolts with a head height according to the dimensions shown in the following
table.
4. When joining magnetic ways together, place the second magnetic way temporarily in line with and at least
30 mm apart from the first magnetic way. Next, match the direction of the magnetic ways (standard mark:
Approx. 4-mm dia. indentation). (Refer to the diagrams in step 2.) Next, while holding the magnetic ways
down so that they are not raised, push the second magnetic way against the first magnetic way and secure
with bolts. Keep fingers clear to prevent them being jammed between the magnetic way due to the mag-
netic attraction pulling the magnetic ways together.
Before installing additional magnetic ways, install the coil assembly. For details, refer to (2) Coil Assembly Installation.
