Installation/Operation Precautions

• Always use (Metric) M8x16 bolts when mounting the rotor to the tower or roof  tripod mounting

plate.

• Take care not to scratch the surface of the rotator or its mounting hardware. If the protective

coating is scratched, the underlying metal may be subject to corrosion or rusting.

• During operation, do not suddenly reverse the rotation during operation, as this places a large load

on the internal components of the rotor. Let the antenna come to a complete stop before reversing
the direction of rotation.

• Do not engage the rotor for more than three minutes of continuous rotation. While this rotor can

operate for up to five minutes continuously, operation must thereafter be halted, and the motor
must be allowed to cool for 

at least

 15 minutes afterwards.

• This rotator is designed to provide centered rotation of a mast with an 

outside diameter

* of

between 48 mm and 50 mm (1.89” to 1.97” O.D.). If it is necessary to use a mast of diameter less
than 48 ~ 50 mm, nearly centered rotation can be achieved using the optional 

 “GL-33” 

 mast

adjustment plate, per the illustrations below.

• The use of a mast of outside diameter greater than 51 mm (2.01”) will result in off-center rotation.

The amount of offset increases with increasing mast diameter. A mast of 60 mm outside diameter
will result in rotation offset from the center by approximately 8 mm.

* Note that commonly-available steel “water pipe” is (A) usually specified in terms of inside

diameter, and (B) designed for holding in liquid under pressure; it is not  particularly designed to
resist bending. Consult with your dealer or a professional tower/antenna installer for assistance
in procuring a mast of specifications adequate for  your antenna system.

Center line

The rotation becomes off-centered for masts
with a diameter of less than 

f

48.

Mast adjustment plate (Option)

Use two plates for mast diameters between 

f

32 and 

f

38.

Use one plate for mast diameters between 

f

39 and 

f

47.

Do not use a plate for mast diameters between 

f

48 and 

f

50.

Insert the mast adjustment plate(s) between the mast and the clamps on the rotor.
