Installation Instructions
Note:
The following installation instructions
assume you are fully capable of installing a gate
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 particular to the 750 Operator.
Preparing the Gate
Before you install the 750 Operator, you must insure
that the gate leaf meets the following criteria.
1. The gate leaf must not exceed the weight and
length constraints for 750 Operator that you
have.
2. The distance between the gate post and the
center of the gate hinge must be at least 2
3
/
8
in.
(6 cm).
3. Make sure the gate leaf has positive stops in both
the opening and closing directions (see Figure 3).
Note
: If you are installing the 750 Operator
with an extension arm, some of the constraints
about the gate leaf may not apply to you. See
the section "Installing an Extension Arm" for
more information on page 26.
Installing the 750 Operator
Installing the 750 Operator consists of the following
steps:
Setting the concrete forms
Installing the power unit
Installing the drive unit
Connecting the hydraulic lines
Synchronizing the hydraulic system
Installing the gate leaf shoe
Installing the gate leaf
Installing the control panel
Adjusting the hydraulic pressures for the operator
Checking the motor rotation
Bleeding the hydraulic system
Adjusting the bypass valves
Set the Concrete Forms
You need to lay out the concrete forms according to the
dimensions shown in Figures 4 and 5. (Your soil
conditions may also determine the size of the cement
footing.)
Note
: If the vertical distance between the finished grade
and the bottom of the gate leaf exceeds 1 1/4 in. (3.3
cm) as shown in Figure 5, you can install a shear-pin
assembly as shown in Figure 9 and as discussed in
“Installing the Gate Leaf Shoe.”
