(1) Magnetic Way Installation
The SGLFM magnetic way is packed with a cardboard sheet covering the magnetic surface, above which is a
thin, rectangular steel plate.
The steel plate is a dummy plate used to reduce the influence of magnetic force on the surrounding environment.
When removing the plate, make sure that fingers are kept clear and that the magnet and magnet protection cover
are not damaged.
Use the following procedure to install the SGLFM magnetic way.
1. Remove the dummy plate used to reduce magnetic force and the cardboard sheet from the magnetic way's
front panel.
2. Align the side of the magnetic way with standard marks (approx. 4-mm dia. indentations) with the stan-
dard surface of the machine base, keeping fingers clear to prevent being jammed.
3. While pressing the magnetic way down closely onto the machine's standard surface, secure with bolts.
Note: Use hexagonal socket head bolts (tensile strength Class 10.9)
