Operating Instructions 3-2 SG8 Manual
Leveling the Machine:
Before leveling the machine, loosen and remove the shipping brackets securing the air float Workhead.
(Figures 1 & 2). The air float clamp plate bolts may need to be loosened also. Access to these bolts is gained by tilting the
spindle assembly to the left and loosening the bolts on that side approximately 1 turn. Access to the right side
bolts is obtained by tilting the spindle to the right. Caution: Do not loosen more than necessary to allow the head to
float. Clamp assembly will not clamp tight if bolts are loosened too much. It is best to hold nylock locking nut secure on
top side and loosen bolt with wrench from underside of clamp plate.
Required machinist level. (Starret 98 or better).
Use the level on the upper float surface, level the machine as precisely as possible, front to back and side to
side. Level is obtained fastest when using a three point leveling method. To utilize a three point leveling method, use only
the front outside leveling bolts and the middle bolt in the rear. Use a socket wrench to turn the leveling bolts. After
the machine is leveled bring in the other leveling bolts. Be certain all leveling bolts are effectively supporting the
machine. Tighten jam nuts on leveling bolts and recheck level.
