Special Notes:
*1 Your gate will usually require more maintenance than the Hy-Security operator that is moving the
gate. Damaged or warped gate panels are signs that a vehicle may have hit the gate. Verify that the
actuator post is not also damaged.
*2 Normally, with correct operator speed, the actuator post should need very little attention. If your gate
panel is very heavy or in high wind area locations the six-month inspection should include a look into the
post itself. Check the mounting base inspection cover you should find it clean. If there is any sign that
the brass bushings have deteriorated or there is wear in the UHMW bearings at the top and bottom of the
square post (a gap of more than 3/8”around the inner tube) further inspection is appropriate.
*3 The anchor bolts at the base of the post should remain tight. If the bolts are loose, there may be an
issue where the supporting post has issues or may be out of plum or the gate may be have been forced.
*4 The support post is the most critical support structure. If there is a problem with the support post, the
gate panel will sag and the mounting base will be shouldering too much of the load. Correct this problem
immediately.
*5 During this inspection you will need to open the limit switch cover, and check that the limit switches
are clean, tight and that the lever arms moves freely without feeling gummy. (The open limit switch is on
the left, close limit on the right)
*6 The oil level should remain approximately one inch below the filler hole. See maintenance instructions
for oil filling. Loss of fluid is not normal and indicates a leak that must be located and repaired. Use
“Uniflow” fluid, part
H 004 1.0 , if additional fluid is required.
