Damper Adjustment:
Due to large variations in ambient
temperature or wear hydraulic
damper adjustment may be required.
Example; In very cold temperatures
damping should to be reduced if the
rotor can not quickly return to rest
position following rotation. In warm
areas, if the rotor fails to stop
smoothly at the rest position and
bounces, then the damping should be
increased.
Before adjusting the damper, loosen
the dial stop screw with 1.2 mm. Allen
key taped on the mechanism.
5.5 Hydraulic Damper Adjustment (Manual Models)
Note:
Damping factor is
increased when dial is turned
clockwise.
Once the adjustment is done, tighten
the stop screw while holding the dial
steady with the other hand.
Caution! Dial is very sensitive. It
must be adjusted carefully in small
increments.
Caution!
To prevent damage due
to bottoming out of the damper
during operation, ensure that there
is approximately 3 mm. clearance
between the damper head and the
body when the damper arm is fully
pushed in. Use loctide on damper
mounting nuts to prevent loosening
by vibration when clearance
adjustment is performed.
