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)
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.
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 turning the red knob
clockwise until snug. (see Figure 3)

DJUST THE OPERATOR PRESSURES
The 400 Operator has an anti-crushing safety device
(operator pressure) which limits the operator’s force if
an obstacle is encountered while the gate is moving.
To adjust the anti-crushing safety device do the
following procedures:
• Lift the key lock cover (figure 3) and insert the
manual release key.
• Turn the key 90° clockwise to open the locking cap
cover.
• Lift up the cover.
• Refer to figure 6 for the following procedures)
• Remove the screw (3) which secures the knob (4)
and then remove the knob.
• Locate the pressure adjustment (by-pass) screws (5
and 6)
