Re-attach the operator to the mounting brackets. Once
the operator is mounted and level, remove the vent
screw from the bottom of the rear flange. (See Figure 1)
Use the 3mm hex key on the end of the screwdriver
provided.
WARNING! Failure to remove the vent screw
may result in erratic operation of the operator or
blown seals.
Slowly move the gate open and close.
WARNING! The piston should not bottom out in
either direction. Doing so will seriously damage
the operator.
Be sure that the gate reaches the positive stop before
the piston bottoms out. Adjust the swivel joint if
necessary.
After checking the swing of the gate, secure all nuts and
bolts, including the jam nut on the swivel joint.
Once the operator is secure, attach the protective cover
to the front flange with the tie rods and end cap
provided.
Note : Lubricating the threads of the protective
cover tie rods can prevent them from freezing up
and breaking if operator is ever removed for
service.
Once the protective cover is installed, swing the gate to
ensure that it does not contact the cover at any point of
the swing.
Re-engage the operator by inserting the key in the
locking cap (see Figure 3) and turning it clockwise until
snug. Remove the key.
