BOLT TIGHTENING
Extreme care should
be taken to see that locking devices are properly installed and to see
that bolts are properly tightened. It is recommended that all in-tank
fastenings be rechecked for tightness after the first 1500 hours of
operation and subsequently at each scheduled shutdown. It is imperative
for proper bolt operation that all agitator shaft and impeller bolts
be torqued to values shown in the Torque Value Table, below:
