Never weld structure with vibrator mounted and wired.
Welding may cause damage to motor windings and bearings.
Use only new Grade 5 bolts and lock nuts to install vibrator.
Old fasteners can break and cause damage to vibrator or
structure.
Do not use split lock washers to install vibrator onto mount.
Damage to vibrator could result.
Tighten mounting bolts in sequence shown in Figure 3. If not
tightened in order, vibrator casting could be damaged.
4. Before installing vibrator onto mount, apply thread sealing compound to
all bolts.
5. Install vibrator onto mount with new lock nuts, compression washers, and
bolts according to Table I. Tighten bolts in order given in Figure 3 to avoid
damaging vibrator casting. (Contact fastener manufacturer for specific
