Premature bearing failure could result.
WARNING
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury.

Weight of the installed segment will cause the wheel to
accelerate in rotation. Failure to maintain control of the
wheel rotation while installing all segments could cause
severe injury to fingers or hand caught between revolving
spokes and the bearing support beam. Handle of hammer,
or other stop, should be inserted through spokes and above
or below bearing support beams to limit rotation of unbal-
anced wheel. See Fig. 33.
