STEP 2. Mount the control box as close to
the operator as possible (recommended
within 5 feet). Use mounting hardware ca-
pable of supporting the weight of the con-
trol box with the battery installed.
Do not mount the control box where
the person using the push button on
the side of the box can come in con-
tact with the gate.
Set the battery inside of the control box
with the terminals toward the front. (Do
not use batteries with side terminals.)

STEP 3: Weld the mounting
bracket on top of the mounting
post. The bracket should be
level and square to the post.
Tack welds may be made from
the top side of the bracket and
post. Bottom welds should be
made for permanent rigidity.

STEP 4: Lay the operator chassis on it’s side. The two ears on the primary arm should
point toward the direction the gate will close. Install the primary arm to the main drive
shaft using the 1/4” key stock and tighten both set screws. The collar on the primary arm
should be installed on the shaft as far as possible.
