INSTALLATION INSTRUCTIONS
Installing the 402 Compact Operator involves preparing
the gate, installing the operator(s), installing the control
panel, and fine-tuning the pressure adjustments on the
operator(s).
Note: The following installation instructions
assume you are fully capable of installing an
operator. This manual does not instruct you in
designing a gate, installing a gate, or basic
electrical wiring. The installation tasks discussed in
this manual are tasks peculiar to the 402 Operator.
PREPARING THE GATE
Before installing the 402 Operator, you need to prepare
the gate itself for the operator. Be sure to do the
following things:
1. Make sure that the gate is plumb.
2. Make sure that the gate moves smoothly on its
hinges without excessive friction by swinging
it open and closed by hand. Lubricate all the
gates’ moving parts.
3. Provide positive stops for the gate leaves in
the fully open and fully closed positions (see
Figure 2).
MANUAL RELEASE MECHANISM
Insert the key and turn it counterclockwise one full turn to
disengage the operator’s hydraulic system (see Figure 3).
