Note: Adjustment can be made in (4) locations to
get desired closed position. Always start with
option “a”
a) Move the gate bracket to left or right of the 36
inch starting position.
b) Change length of connecting rod assembly.
c) Relocate control arm extension on control arm to
a different hole pattern then start position. See
figure #6.
d) Move connecting rod bolt in gate bracket to a
different hole. See figure #8.
7. Move control arm to its open position. See figure #9.
Note: Arm and connecting rod should almost double
over each other. This is important for smooth operation
and longevity of the operator.
Note:
Open position of gate may be adjusted slightly
with limit switch adjustment, but when finished, open
position on control arm assembly should be as close
as possible to that shown in Figure 9. If mechanical
adjustments are made to achieve desired open position
of gate, repeat steps 6 & 7, since this will affect the
closed position.

8. When the desired open and closed gate position have
been achieved, remove control arm extension from
control arm. See figure #6.
9. Remove control arm from operator drive shaft and insert
drive key. See figure #6.
10. Replace control arm on operator drive shaft with drive
key and secure with 3/8 inch bolt. See figure #6.
11. Replace control arm extension on control arm and
secure with hand knobs. See figure #6.
Note: If operator was ordered as a right or left hand
unit from the factory, the control arm position will be
somewhere in its normal travel segment and the limit
switches will be set at an approximate open and close
position. Final adjustments will be made later after
power is connected.
If the hand of the operator is to be changed in the field
as described in the following section than before the
control arm extension is replaced as in step #11,
proceed to step #12.
12. By turning the internal drive pulley by hand, move the
control arm to somewhere in its normal drive segment.
13. Control arm extension may now be attached to control
arm as in figure #6.
