Preventive Maintenance & Adjustment

Fasteners

Before operating your Brillion machine, check all
hardware for tightness. Use the Tightening Torque Table
reproduced below as a guide.

General Torque Specifications (rev. 4/97)

After a few hours of use, check entire machine and
tighten any loose nuts or bolts. Daily or periodic checks
should be made thereafter.

TORQUE SPECIFIED IN FOOT POUNDS

This chart provides tightening torques for general purpose applications when special torques are not specified on process or

drawing. Assembly torques apply to plated nuts and capscrews assembled without supplemental lubrication (as received condition).
They do not apply if special graphite moly-disulfide or other extreme pressure lubricants are used. When fasteners are dry (solvent
cleaned) add 33% to as received condition torque. Bolt head identification marks indicate grade and may vary from manufacturer to
manufacturer. Thick nuts must be used on grade 8 capscrews. Use value in [ ] if using prevailing torque nuts
