2. Insert the mounting bolts into one side of the magnetic way yoke and tighten lightly by hand. Next, while
firmly holding down the magnetic way yoke onto the positioning step, tighten the bolts firmly.
Note: The following conditions apply to these values.
• Machine material: Steel
• Hexagonal socket head bolts (tensile strength Class 10.9)
3. After removing the mounting spacer bolts on the side of the magnetic way yoke installed first, firmly hold
down the other magnetic way yoke onto the positioning step, while tightening the bolts firmly. Make sure
that the magnetic way yoke does not slip into the path of the coil assembly.
4. Fully remove the spacer used for transport. If the bolt holes used for mounting the magnetic way are in the
position where the mounting spacer was mounted, tighten the bolts at these locations.
5. 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, while pushing the second magnetic way against the first
magnetic way, secure with bolts. Keep fingers clear to prevent them being jammed between the magnetic
ways due to the magnetic attraction pulling the magnetic ways together.
Follow the same procedure as in steps 1 to 4 to install the second and subsequent magnetic ways.
