b. The Radial Arms should maintain their posi-
tion without drifting yet move freely around the hub.
Normally this adjustment is correct from the factory
and does not change. If the Radial Arms drift, the
most probable cause is an unlevel mounting plate.
NOTE
Recheck the mounting plate to make
sure it is absolutely level. In most cases
releveling the plate will solve any drift-
ing problem.
c. If releveling the mounting plate does not
correct the drift, or the Radial Arms are difficult to
move, the bearing preload must be adjusted. This
requires the use of special tools. Contact your
SKYTRON dealer for assistance.
