Never weld structure with vibrator mounted and wired!
Welding may cause damage to motor windings and bearings.

Vibrators last longer and are more effective when bolted to a rigid mount.
Mounting plate must be totally flat!
Warped surface can cause body stress and possible cracks.
Take an amp reading to make sure that the unit is not drawing more than the specified amps.
In situations of high amp draw, reinforce the mounting area
or relocate it until rated amp draw is achieved
.

BOLTS
Use only new bolts of grade 5 (or 8)!
Old bolts can break and cause damage to vibrator or structure.

Always use compression washer(s)!
Locking nuts are also recommended.
Do not use split lock washers:damage to the vibrator could result.
Cross tighten mounting bolts! If not, the vibrator casting could be damaged
At startup re tighten after two hours of operation!
Periodically check bolts to ensure tightness.
