Lubrication
To lubricate the elevating gear
apply a liberal amount of
silicone spray lubricant to the
elevating gear with the lift in
the down position, then run the
lift up and down a few times to
distribute lubricant over gears.
Lubricating Rotating Gear Housing
In the event that rotating the antenna becomes difficult,
lubricating the bearing surface between the rotating gear
housing and the base plate can restore normal operation.
Any spray type silicone lubricant may be used.
Elevate antenna and remove setscrew from rotating gear
housing as shown. Spray lubricant into hole and around
edges of gear housing. Rotate gear housing until lubricant
coats bearing surfaces and antenna rotates freely.
