2-18 Installation
9. Position the slide over the complete sections and continue aligning the
remainder of the plates.
10. If the area where the magnet plates are to be installed does not allow you
to use a straight edge describes above, an alternate method of aligning
plates can be done. Space the plate by using a 0.020 plastic shim between
the magnet plates, tighten the bolts, and then remove the shim.
11. Once all the alignment is completed, torque all bolts to values listed in
the tables.When considering torque values for mounting hardware, take
into account the magnet plate, mounting surface and mounting
hardware. Per Table 2.N secure all assemblies in place using all
mounting holes.
ATTENTION
!
Remove alignment tool and make certain all magnet plate
mounting hardware is flush or below magnet surface to
prevent damage to the coil.
