CHECKS AND OPERATIONS PRIOR TO THE INSTALLATION OF THE OPERATOR

3.0     CHECKING THE GATE

•   Before proceeding with the mounting, do a complete check on the gate leaves making sure that they are in good condition and 

not broken or damaged in any way.   

•    Ensure the motion of the gate leaves is uniform and the hinges have no play and do not rub.
Otherwise, hinges must be repaired so that the gate leaves can be moved easily by hand or, if repair is impossible, hinges must 
be replaced.
•   Check that the gate leaves are plumb (when perfectly still at any point in the swing) (

B1B

); when the gate leaves are completely closed, 

check that the closure is even throughout the whole height of the gate leaves.

•   Using a dynamometer, check that the opening and closing effort of the gate, to be measured from the end of the gate leaf, does 

not exceed 15 kg (147 N).

Before deciding on the fi nal position of the mountings, it is necessary to:
•   Choose the most suitable height on the gate leaf for the operator front mounting. If possible, it should be positioned halfway up the 

gate leaf. As a rule, the ideal point is always in the strongest area where the fi xing of the gate leaf has the least effect. If there is not a 
broad strip of steel in the gate framework, then a suitable support needs to be welded on in the area where the front mounting is to be 
positioned in order to spread the load over a wide zone  (

B1A

).

•    Check whether the chosen area needs reinforcing or strengthening in any way. Make the same check on the gate leaf support posts.

3.1     CHECKING THE OPERATOR COMPONENTS

Check that the model code displayed on the operator packaging 
corresponds to the code on the identifi cation plate on the operator 
itself (

B3

).

Also,before starting with the mounting procedure, check that the 
packaging contains all the components listed below (

B4

) and that 

none of them is damaged.
