IMPORTANT

Before operating your Brillion machine, check all

hardware for tightness. Use the Tightening Torque Table

below as a guide. See Table 4-1.

After a few hours of use, check entire machine and

tighten any loose nuts or bolts. Daily or periodic checks

should be made thereafter.

When replacing bolts, be sure to use fasteners of equal

grade.

• Values are given in foot-pounds.

• Use GRADE B lock nuts with GRADE 2 and GRADE 5

bolts only.

• Use GRADE C lock nuts with GRADE 8 bolts only.
