7.3 VERIFICATION OF SNAP RINGS
The universal bearings have two snap rings each which prevent the actual bearing
from popping out of its cage. Verify that the snap rings are lodged securely in their
respective grooves. If any appear to be loose, push them back in place using a
screw driver or other sharp object and check daily to make sure the problem does not
repeat. If the problem persists, contact your distributor or manufacturer for a
replacement part.
7.4 CHECKING WELD CONDITION
Visually check all the weld areas of the outer frame for signs of cracks or failure.
None is acceptable. If any problems are found, contact your distributor or the
manufacturer.
7.5 CHECKING THE ACTUATOR DRIVE BELT
