Lubrication
LUBRICATE ANY and ALL WORKING PARTS with light oil at the beginning of each work
day for best performance! It is especially important to lubricate the locking mechanism inside the
latch box (#1).
Instruction For Reversing Headgate Operation
TO REVERSE HEADGATE OPERATION FROM THE LEFT SIDE TO RIGHT SIDE, FOLLOW
THESE INSTRUCTIONS. (NOTE: ALL HEADGATES ARE SHIPPED FROM THE FACTORY WITH
THE CONTROLS ON THE LEFT SIDE.) Also, when referring to the left or right of the headgate,
consider how the animal stands in the headgate“their right or their left”.
1. Remove operator handle (#8) by removing two ½" bolts
and reattach handle to right side of
headgate.
2. Remove automatic selector lever (#9) by loosening and removing eyebolt from the lower end
of the 10" spring. Now pull selector lever out through the top of the gate. Reinstall on right
side by reversing this procedure. NOTE: You will need a screwdriver to stretch the 10"
spring in order to get the eyebolt into bottom bracket.
3. Disconnect the automatic slide rod (#4) from one end by removing the lynch pin and sliding
the rod out of the holes. Now slide t
he automatic slide tube with setting slots (#3) off the
automatic slide rod (#4). Now reverse the automatic slide tube with setting slots (#3), end-to-
end and slide it back onto the automatic slide rod. This process will have the automatic trip
control handle (#5) on the opposite side of the gate. The handle will be turned “up”. To
position it “down”, loosen the locking nut that holds it locked in that position. Now, rotate
the handle “down” and retighten the lock nut.

Gate is slow to close in automatic position, or
does not close and cow backs out.

in notch of operator handle.
2. Lubricate all moving parts.
3. If necessary, tighten spring at eye bolt
to desired tension.
