Inward swinging
: You should be able to push
the cylinder in about an inch.
Outward swinging
: You should be able to pull
the cylinder out about an inch.
If the worm screw was not at the full extent of its
travel when attached to front mounting bracket, then
with the operator detached from the front mounting
bracket, permanently attach (weld) the front mounting
bracket to the gate leaf (see Figure 10).
If the worm screw was at the full extent of its travel,
try moving the front mounting bracket toward the
